128-bit Encryption

128-bit encryption means that the data cryptographically encoded during an Secure Sockets Layer (SSL) session is at the highest level currently available, and nearly impossible to break. Compared to a 40-bit encrypted SSL certificate, a 128-bit is more than 300 septillion (300,000,000,000,000,000,000,000,000) times stronger. All certificates offered through LogicalPages.com are encrypted at 128 bits.

200
Is a browser code that signals that the website page was opened successfully.

301
Is a browser code that signals a directory was requested instead of a file. The server substituted an index.htm file

302
Is a browser code that signals a temporary redirection to another page/location.

400 Bad Request - The Apache Web server allows site managers to override the standard error page that is served for specific errors by number. This error, 400 bad request, means that a request for a URL has been made but the server is not configured or capable of responding to it. This might be the case for URLs that are handed-off to a servlet engine where no default document or servlet is configured, or the HTTP request method is not implemented.

401 Unauthorized -Your IP address or the username/password you entered were not correct. Your request was denied as you have no permission to access the data.

402 PaymentRequired - The data is not accessible at the time. The owner of the space has not yet payed their service provider.

403
Is a browser code that means the browser understands what to do, but can't do it for some reason.

404
Is a browser code that means the requested web address cannot be found.

405 Method Not Allowed - Your IP address or the username/password you entered were not correct. Your request was denied as you have no permission to access the data.

OR The server was unable to serve the data that was requested.

406 Not Acceptable - The document that has been requested either no longer exists, or has never existed on the server.

407 Proxy Authentication Required - The browser has not been authenticated on the required proxy server to access the data. This error is probably most commonly returned by content filters/parental controls.

408 Request Timeout - The browser has not been authenticated on the required proxy server to access the data. This error is probably most commonly returned by content filters/parental controls.

409 Conflict - Too many requests for the same file at one time.

OR

There is a conflict with an established software rule. (ie: you are trying to copy over a file with an older version, or you do not have permissions to delete a file)

OR

This could be caused by a DNS issue.

410 Gone - This is like a 404 error in that the document requested is not on the server, however this differs in that the server 'knows' that the file used to be there and 'believes' that the file may be back, so it returns 410 rather 404.

411- Length Required: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) should include a 'Content-Length' specification. This is typically used only for HTTP methods that result in the placement of data on the Web server, not the retrieval of data from it.

412- Precondition Failed: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) included a 'Precondition' specification which the server detected was not met.

413- Request Entity Too Large: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was simply too large i.e. too many bytes. What constitutes 'too many bytes' depends partly upon the operation being attempted. For example a request to upload a very large file (via the HTTP PUT method) may encounter a ceiling on upload file size set by the Web server.

414- Request- URI Too Long: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) contains a URL that is simply too large i.e. too many bytes.

Typically Web servers set fairly generous limits on length for genuine URLs e.g. up to 2048 or 4096 characters. If your URL is particularly long, you can usually try shorter variations to see roughly where the limit is. If your long URL is indeed valid, then the Web server may need to be reconfigured to allow your URLs through. Understand that Web servers have to set some reasonable limit here, because they have to deal with badly programmed clients trying to give them huge garbage URLs.

415- Unsupported Media Type: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) identifies a URL resource whose actual media type 1) does not agree with the media type specified on the request or 2) is incompatible with the current data for the resource or 3) is incompatible with the HTTP method specified on the request.Detecting exactly what is causing this problem can be difficult, because there a number of possible reasons. Often the request involves transfer of data from the client to the Web server (e.g. a file upload via the PUT method), in which case you need to confirm with your ISP which media types are acceptable for upload.

500
Is a browser code that means there was an error in displaying a webpage.

501- Not implemented: Your Web server does not understand or does not support the HTTP method it finds in the HTTP data stream sent to it by the client (e.g. a Web browser or our CheckUpDown robot).

502- Bad Gateway: A server (not necessarily a Web server) is acting as a gateway or proxy to fulfill the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server received an invalid response from an upstream server it accessed to fulfill the request.This usually does not mean that the upstream server is down (no response to the gateway/proxy), but rather that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, it often means that one or both machines have been incorrectly or incompletely programmed.

503- Service Unavailable: Your Web server is currently unable to handle the HTTP request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. Some servers in this state may also simply refuse the socket connection, in which case a different error may be generated because the socket creation timed out.

504- Gateway Timeout: A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.This usually means that the upstream server is down (no response to the gateway/proxy rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.

505- HTTP Version Not Supported: Your Web server does not support, or refuses to support, the HTTP protocol version specified by the client (e.g. your Web browser or our CheckUpDown robot) in the HTTP request data stream sent to the server.The HTTP protocol has various versions identified as major.minor e.g. version 0.9, 1.0 or 1.1. Your server is indicating that it is unable or unwilling to complete the request using the major version provided by the client - other than with this error message.Assuming that your request identifies a valid major.minor version number (the request is not fundamentally corrupt), then this error should mostly only occur if you are trying to use version 1.0 or 1.1, but your

Web server only supports the older 0.9 version.


506
Is a browser code that signals ASP is not enabled for the domain name.

507
Is a browser code that means there is likely an error with the coding of a ASP page.

A

A Record

All servers connected to the Internet are assigned a unique IP address. An "A record" associates a name to the server's IP address. This allows people to utilize easy-to-remember domain names instead of hard-to-remember IP addresses to connect to a Web site. For example, you could type in 65.99.213.19 into your Web browser to get to the LogicalPages Web site, or you could simply type in www.logicalpages.com.

ACK (Acknowledge)

An acknowledgement (approval) from an authorized point of contact for a domain name record, contact record, or host record that a requested modification should be completed. When a modification request is received from a source that is not an authorized contact, the request will be rejected and a message will be sent to the listed contacts asking them to ACK (approve) or NACK (disapprove) the modification.

Administrative Contact

The Administrative Contact is an individual authorized to interact with LogicalPages.com on behalf of the domain name Registrant, and who has full authority to make updates to the domain name, including contact information and name server information. The Administrative Contact should be able to answer non-technical questions about the domain name's registration and the domain name Registrant.

Backup - A saved copy of the files for your website. It can be used to restore your site if anything happens to the original files.

Bandwidth

Bandwidth is the amount of data that can be transmitted in a time period over a communications channel, often expressed in kilobits or gigabytes per second. When people visit your site, data is sent from our servers to their computer. This data can be composed of web pages or anything else on your site that can be viewed or downloaded by visitors. It also include email received and downloaded to your PC. Every month this requested data is added up, to give your total data transfer. All of LogicalPages' hosting packages come equipped with more then enough bandwidth to keep your system running at full capacity.

Billing Contact

Bounce - An email message that is returned to the sender because it was undeliverable.

Broadband - High-speed internet access.

C


ccTLD

A ccTLD is a Country Code Top-Level Domain. Each ccTLD belongs to a particular recognized country, and each country gets to decide how the Registry for domains within that ccTLD should be run. Some countries run their registries themselves; others delegate this job to ISPs or other networking companies.


CGI(Common Gateway Interface)

CGI is the most common way for web servers to interact dynamically with users. It works by passing data from a server to a CGI program, designed to receive and return data. CGI is a popular interface used to create server-based web applications with languages such as Perl or C.

Cgi-bin

A directory on the web server where CGI scripts reside. Websites must have a cgi-bin in order to run CGI programs.

Change Of Registrar Request (CRR)

If you have domain names registered with another registrar, you can transfer them to LogicalPages.com and consolidate them with your already existing registrations. This is known as a Change of Registrar Request – a request to transfer a registered domain name from one registrar to another registrar.

Contact

For domain registrations, contacts are individuals or groups who represent the Registrant on matters related to the Registrant's domain name. There are three types of contacts: Administrative, Technical, and Billing. The entity listed as the Administrative, Technical, or Billing contact should be the entity best able to answer questions about that particular aspect of the domain name's registration.

Contact Handle

The unique identifying code for a registrant linked to a file in the registry, which contains contact information. Registrants are assigned a contact handle at the time of their first domain name registration.

CNAME Record

The CNAME Record, short for "Canonical Name", allows you to create alias names to existing Internet host records. CNAME records are helpful when pointing multiple domain names to the same host. Be careful using CNAME records. Only persons highly familiar with DNS should attempt to use CNAMES, or you could create routing problems for all of your DNS information including your Web site and e-mail.

cPanel

cPanel is a popular website management tool. The software is designed for the web space end users and provides them with full control of their web space. LogicalPages offers cPanel to our customers on all our hosting packages. http://www.LogicalPages.com/cpanel.html/

LogicalPages offers CubeCart to our customers who choose cPanel as their control panel of choice. http://www.cubecart.com/

D


Deactivation

When a Web address is deactivated, it can no longer be translated into the numerical addresses used by the network. When deactivated, a web address ceases to function as an Internet address. When a domain name is deactivated, the Domain Name System (DNS) will no longer have the information needed to resolve the domain name to its corresponding Internet Protocol (IP) number(s), effectively disabling the domain name as a tool for locating the related computers or organizations. 

Deletion

The process of removing a domain name and its corresponding record from the Domain Name System (DNS) and the LogicalPages domain name database. A deleted domain name cannot be used to locate computers on the Internet and will be made available for other parties to register on a first-come, first-served basis. A domain name may be deleted at the request of the domain name Registrant, as a result of non-payment of fees, or due to circumstances particular to individual cases.

Disk Space

Disk Space is the amount of pysical storage space given to a web site. The more disk space you have the more pictures, HTML files, videos, programs and email you will be able to store on our server. All of LogicalPages's hosting packages come equipped with more then enough disk space to keep your system running at full capacity.

Distribution Partner

Providers who buy domain names for a significant discount to resell to and provide real-time domain name registrations directly to customers from their Web sites.

Domain

A subset of the total domain name space. A domain represents a level of the hierarchy in the Domain Name Space, and is represented by a domain name. For example, the domain name logicalpages.com represents the second level domain "logicalpages" which is a subset, or sub-domain, of the top-level domain .com. .com is in turn a larger subset of the total Domain Name Space. If you think of the Domain Name Space as a tree, a domain would be analogous to a limb and would encompass all of the branches off of that limb.

Domain Name

A unique, meaningful and easy-to-remember name for an Internet address (such as LogicalPages.com), that corresponds to a series of numbers (internet protocol numbers), which locates an organization or other entity on the Internet. It must be different than all other domain names, workgroup names, and computer names on the network and have two or more parts separated by dots. Once registered, the domain name belongs to the registrar for as long as they continue to pay and follow the terms of use. An example of a Domain Name is www.LogicalPages.com.

Domain Name Disputes

Disputes that arise over conflicting positions as to who has the right to register a specific domain name. Disputes often occur when a domain name that is the same, or similar to, a valid registered trademark is registered by a party that is not the owner of the registered trademark. A central factor in domain name disputes is the fact that domain names at the same level of the hierarchy must be unique. See our Domain Name Dispute Resolution Policy.

Domain Name Dispute Resolution Policy

The policy became effective January 1, 2000. Under this policy, neutral and accredited dispute resolution service providers will resolve disputes. Here's how the current policy differs from the previous policy:

Domain Name Registrar

See Registrar

Domain Name Server

Domain Name Server is a program running on a server which automatically translates domain names (http://www.LogicalPages.com/) into their correct TCP/IP addresses (72.21.39.84). Whenever you request a web page the web browser must consult the domain name server to find out what the numeric translation of the URL is. This is necessary because computers only understand the numeric IP address, whereas we humans prefer to use meaningful and more memorable text.

Domain Name System (DNS)

Domain Name System is the system that translates internet domain names into IP numbers. It provides a physical location (IP address) for each hostname, and lists the mail exchange servers accepting email for each domain.


Domain Protect

Domain Protect adds an extra layer of protection to your domain name registration, guarding it against unauthorized domain name transfers. Every domain name registration with LogicalPages comes with the free Domain Protect feature. When turned on, Domain Protect helps to block the transfer of your domain name to another registrar. It provides protection from "domain hijackers," or others who may attempt to authorize a transfer of your domain name registration. With Domain Protect turned on you can still renew and modify domain names, including performing legal name changes. To transfer a domain name to another registrar, you must first turn off Domain Protect.

E


Ecommerce

Ecommerce is business that is conducted over the internet using different types of applications. It includes consumers using the internet to purchase goods and services online; as well as businesses selling and communicating with other businesses through the internet. This is usually done with a 'shopping cart' on the page, and the buyer can purchase with their credit card. LogicalPages offers a variety of Ecommerce programs with your control panel on all hosting packages.

Email Address

This refers to an electronic mailing address to which email may be sent and received.

Email Aliases

An Email Alias is an address that forwards all email it receives to another email account. Email aliases are often used to create replacements for long or difficult-to-remember email addresses. They can also be used to create generic email addresses such as sales@yourcompany.com and info@yourcompany.com. LogicalPages provides our customers with unlimited email aliases on all hosting packages.

Email Forwarding

Email Forwarding is a service that automatically forwards your email to an existing email account. This is extremely helpful if you have more then one email account. With email forwarding you send and receive email in the same way that you always have while looking far more professional. LogicalPages provides our customers with unlimited email forwarding on all hosting packages.

Extensions

LogicalPages offers a variety of domain name extensions. Protecting brand identity has become very important, so often customers will register multiple extensions and variations of their domain names.

Expiration Date

The expiration or anniversary date for your domain name is directly related to the length of service you requested during your registration or renewal transaction. To find the expiration date for your domain name, check out your WHOIS record . Your expiration date is shown at the bottom

I

The Internet Corporation for Assigned Names and Numbers (ICANN)

The nonprofit body responsible for oversight of the domain name system and for accrediting domain name registrars. 

Internet Protocol (IP) Numbers (IP addresses)

A unique, numeric identifier used to specify hosts and networks. Internet Protocol (IP) numbers are part of a global, standardized scheme for identifying machines that are connected to the Internet. The IP Address is the numeric address that refers to a specific machine or resource on the Internet. Every server on the internet has at least one IP address that uniquely identifies it from all other computers on the Internet.

Technically speaking, IP numbers are 32 bit addresses that consist of four octets, and they are expressed as four numbers between 0 and 255, separated by periods, for example: 65.99.213.19.  

J


Java

Java is a scripting language which enables web designers to add dynamic, interactive elements to a web site through special programs called applets.

Modification

The process of updating an existing domain name record, contact record, or host (name server) record to reflect changes in existing information. Modifications include: changing information on an existing contact record; replacing an existing contact on a domain name record with a new contact; changing information on an existing host record; changing the name servers listed on an existing domain name record; changing information about the organization who registered a domain name (there are some cases when changes in the organization's name may require a new, separate registration). There is no additional charge to modify an existing domain, contact, or host record. Keeping these records up to date is critical to the smooth operation of the Domain Name System (DNS), and it is the responsibility of the registrant to ensure that domain name record(s) are kept up to date.

Mozilla - The organization that produces the Mozilla suite of applications as well as Firefox (a browser) and Thunderbird (an email client).

MX Record (Mail Exchange Record)

MX ("Mail eXchange") records are used to determine the delivery route for your E-mail. For example, if you want to host your own mail server for the domain in your account, you will need to specify the mail server names as MX records.

In addition, you can specify multiple mail servers and rank them by priority in the event the primary mail server is not responding. If you give the same rank to different mail servers, the traffic load to those servers will be shared. Mail will be delivered to the server with the lowest priority number.

Perl scripts are not embedded within HTML pages and do not download to the web browser but reside on the server. It is widely used to write web server programs for such tasks as automatically updating user accounts and newsgroup postings, processing removal requests, synchronizing databases and generating reports. LogicalPages offers PERL pre-bundled with either cPanel or Plesk control panel. http://www.perl.com/

Permissions - a set of permissions associated with every file and directory that determine who can read it, write to it, or execute it. Only the owner of the file (or the super-user) can change these permissions.


PHP(Hypertext Preprocessor)

PHP is an open source server-side, HTML embedded scripting language used to create dynamic web pages and interact with databases. Because PHP is executed on the server, the viewer cannot see the code. PHP is basically used for developing web based software applications. LogicalPages offers PHP pre-bundled with either cPanel or Plesk control panel. Currently we have PHP 4.4.4 installed on all accounts. http://www.php.net/

PHPBB(Discussion boards)

PHPBB is a popular free and open source forum system using the PHP scripting language and supporting a variety of database management systems including MySQL, PostgreSQL, MSSQL, Microsoft Access and, with modification, Oracle. LogicalPages offers PHPBB to our customers on both Cpanel and Plesk control panels. http://www.phpbb.com/

PhpMyAdmin

PhpMyAdmin is an open source, powerful web-based interface for administering MySQL databases. It is written in the PHP scripting language and makes it easy to create database driven sites with almost no knowledge of SQL code. LogicalPages offers PhpMyAdmin pre-bundled with either cPanel or Plesk control panel. http://www.phpmyadmin.net

Picture Gallery (Photo Gallery)

Picture gallery is a display of pictures in one given area. Pictures are used on web sites to make them more visually appealing to visitors and also for displaying your personal collection. LogicalPages offers a variety of picture gallery programs with your control panel on all hosting packages such as Coppermine Photo Gallery (cPanel & Plesk), Gallery (cPanel & Plesk) and 4images Gallery (cPanel).

POP3/IMAP4

POP3 is the method of delivering email from the mail server to the client machine. IMAP is used for accessing email on a remote server from a local client. IMAP and POP3 are the two most prevalent Internet standard protocols for email retrieval.

PostgreSQL

PostgreSQL is an open source software object relational database management system that allows you to store and retrieve data according to various parameters given in a query. PostgreSQL is an alternative to MySQL. LogicalPages offers PostgreSQL pre-bundled with either cPanel or Plesk control panel. http://www.postgresql.org/

Pretty Good Privacy (PGP)

A program used to encrypt and decrypt e-mail over the Internet. It can also be used to send an encrypted digital signature that lets the receiver verify the sender's identity and know that the message was not changed en route.

Primary Server

The host name and Internet Protocol (IP) number of the name server contains authoritative information for the domain name and is used to resolve that domain name to its corresponding IP number(s). The designation of "primary" means that this name server is first and relied upon before any of the other name servers that may be listed on the domain name registration.

Private Key

An encryption/decryption key known only to the party or parties that exchange secret messages.

Public Key

A public key is a value provided by some designated authority as a key that, combined with a private key derived from the public key, can be used to effectively encrypt messages and digital signatures. In a public key system, each user has a publicly known encryption key and a private key known only to that user. Messages are encrypted using the receiver's public key. When they receive it, they decrypt it using their private key.

Python

Python is an interactive programming language often compared to PERL or Java. It combines remarkable power with very clear syntax and has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. LogicalPages offers Python pre-bundled with the cPanel control panel. http://www.python.org/

R


Registrant

The individual or organization that registers a specific domain name. This individual or organization holds the right to use that specific domain name for a specified period of time, provided certain conditions are met and the registration fees are paid. This person or organization is the "legal entity" bound by the terms of the Service Agreement.

Registrar

(or "Domain Name Registrar") An organization or individual that acts on behalf of a registrant to register a domain name and manage updates and changes to that name record thereafter.

Registry

The Internet Registry manages the Internet's domain name system, the formal recording of a domain name, and its authorized contact DNS server information. 

Registrant Name Change Agreement

The method by which a domain name Registrant changes its name as it appears in LogicalPages records. Specifically, the Registrant Name Change Agreement must be used if the Registrant wishes to:

To make these types of changes, complete the Registrant Name Change Agreement.

Registration

The process through which individuals and organizations obtain a domain name. Registration of a domain name enables the individual or organization to use that particular domain name for a specified period of time, provided certain conditions are met and payment for services is made.

Renewal

The process of reinitiating a domain name's registration for a specified period of time and paying the renewal fee. 

Resolve

The term used to describe the process by which domain names are matched with corresponding Internet Protocol (IP) numbers, making the web site accessible on the Internet. "Resolution" is accomplished by a combination of computers and software, referred to as name servers, which use the data in the Domain Name System to determine which IP numbers correspond to a particular domain name.

Router - A network device that forwards packets from one network to another. Based on internal routing tables, routers read each incoming packet and decide how to forward it. To which interface on the router outgoing packets are sent may be determined by any combination of source and destination address as well as current traffic conditions (load, line costs, bad lines, etc.).

RSS -(Really Simple Syndication) A syndication format that was developed by Netscape in 1999 and became very popular for aggregating updates to blogs and the latest news from Web sites. RSS has also stood for "Rich Site Summary" and "RDF Site Summary."

S

Scalability - How much a system can be expanded.

Script

A script is a type of program that consists of a set of instructions for another application or utility to use.

Search engine - Software that searches for data based on some criteria. Although search engines have been around for decades, they were brought to the forefront after the Web exploded onto the scene. Every Web search engine site uses a search engine that it has either developed itself or has purchased from a third party. Search engines can differ dramatically in the way they find and index the material on the Web, and the way they search the indexes from the user's query.

Second Level Domain (SLD)

The next highest level of hierarchy underneath the Top Level Domain (TLD). The portion of the domain name that comes before the "." Identifies the specific and unique administrative owner associated with an Internet Protocol address (IP address).

Secure Sockets Layer (SSL)

SSL is a commonly used protocol for managing the security of message transmissions in a network. SSL works by using a private key to encrypt important data, such as credit card numbers, that's transferred over the SSL connection.

Secure Sockets Layer (SSL) Certificate

SSL stands for Secure Sockets Layer, which is the standard security technology for creating an encrypted link between a Web server and a browser. This link ensures that all data passed between the Web server and browser remains private and secure. Your site visitors will know they have created an SSL link with your Web server when they see the "https://" at the beginning of the URL as well as the padlock icon in the lower right-hand frame in their Web browser.

Security - The protection of data, networks and computing power. The protection of data (information security) is the most important. The protection of networks is important to prevent loss of server resources as well as to protect the network from being used for illegal purposes. The protection of computing power is relevant only to expensive machines such as large supercomputers.

SEO (search engine optimization) - Designing a Web site so that search engines easily find the pages and index them. The goal is to have your page be in the top 10 results of a search. Optimization includes the choice of words used in the text paragraphs and the placement of those words on the page, both visible and hidden inside meta tags. Search engines use different criteria for indexing, and those criteria may change. Thus, it becomes increasingly difficult to satisfy every one equally. Yahoo! and other directory-oriented search sites manually index a Web site, which may provide the best results for the user.

Servers - A computer system in a network that is shared by multiple users. Servers come in all sizes from x86-based PCs to IBM mainframes. A server may have a keyboard, monitor and mouse directly attached, or one keyboard, monitor and mouse may connect to any number of servers via a KVM switch. Servers may be also be accessed only through a network connection as well.

Shared Hosting

Shared Hosting is a hosting option whereby several client websites are housed on and share the resources of a web server. LogicalPages offers four powerful Shared Hosting packages to choose from. Please click here to view our available plans: http://www.LogicalPages.com/features.html

Shared Registry System (SRS)

LogicalPages offers a variety of Sitebuilder tools with your control panel on all hosting packages such as Soholaunch Pro Edition and Templates Express.

SMS - Short Message Service. A service that permits the exchange of text messages via mobile phones.


SMTP (Simple Mail Transfer Protocol)

SMTP is the primary protocol used for sending email messages between servers. Most email systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an email client using either POP or IMAP.

Spam – Unsolicited bulk email. Unsolicited means that the Recipient has not granted verifiable permission for the message to be sent. Bulk messages are messages that are sent massively and contain identical content.


Spam Assassin

SpamAssassin is a computer program used for email spam filtering based on content-matching rules, which also supports DNS-based, checksum-based and statistical filtering, supported by external programs and online databases. Spam Assassin is known as one of the most effective spam filters, especially when used in combination with spam databases. LogicalPages offers Spam Assassin to our customers through the cPanel control panel.

Spider – A program that surfs webpages to get the links and pass the caught links to another program to be processed. It is usually used by search engines.

Spoofing – Email address spoofing is an activity of illegally using other’s legitimate email address to send messages.

Spyware – A program that is installed without user’s consent and running secretly on computer to collect user’s information and pass it to other parties. Spyware is installed as a result clicking on unreliable popup windows or drive-by download (automatic download without user’s consent and knowledge).



SSI (Server Side Includes)

SSI is commands that can be embedded in web pages that are processed by the web server when a user requests a file. The most common usage of SSI is the inclusion of common menus, headers and footer elements for a page. LogicalPages offers SSI pre-bundled with either cPanel or Plesk control panel.

SSL (Secured Sockets Layer)

See Secured Sockets Layer

Storage – Space in hard disk to store data such as webpages, databases and configuration files. Each user account is assigned a storage quota on the server.

Streaming – To transmit data over a network. Video and Audio streaming mean to upload, download or play Video and Audio file.

Sub Domain (Subdomain)

A sub domain is a subdivision of a larger domain. Usually the subdomain is a descriptive name placed before the main domain. For example, "support.LogicalPages.com" is a subdomain of "LogicalPages.com." Another example would be mail.domain.com, where domain.com's mail users would check their mail. All of LogicalPages's hosting packages come with unlimited subdomains.

Swish – A program that is used to create Flash animations without using Macromedia's Flash product.

T


Table - A set of data elements that has a horizontal dimension (rows) and a vertical dimension (columns) in a relational database system. A table has a specified number of columns but can have any number of rows. A table is often called a relation. Rows stored in a table are structurally equivalent to records from flat files in that they must not contain repeating fields. In webpage’s it can be as simple as a spreadsheet of rows and columns, or as complex as a set of data within a database.

tcp - (Transmission Control Protocol) one of the main protocols in TCP /IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

Technical Contact

The Technical Contact is the person or organization who maintains the primary domain name server. The Technical Contact should be able to answer technical questions about the domain name's primary name server and work with technically-oriented people to solve technical problems that affect the domain name. The contact that has the authority to update name server information but not the authority to transfer ownership or administrative rights.

Telnet - A terminal emulation program for TCP /IP networks such as the Internet. The Telnet program runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password. Telnet is a common way to remotely control Web servers.

Template - A set of pre-designed formats for text and graphics on which new pages and webs can be based. After a page or web is created using a template, you can customize the page or web.

Temporary URL - Lunarpages will create a temporary url for a customer if they request it while their own domain name is being registered and propagated. This is typically done when advanced web hosting functions such as php, jsp, asp, etc are needed immediately or for a testing purpose. The temp url is made into the form of subdomain.lunarpages.net where the customer can choose their subdomain name.


Third Level Domain

In the Domain Name System (DNS), the next highest level of the hierarchy underneath the second level domains. In a domain name, that portion of the domain name that appears two segments to the left of the top-level domain. For example, the reston in reston.va.us. Third level domains are not the portion of an email address that appears in front of the @ symbol - for example, the webmaster in webmaster@logicalpages.com is not a third level domain.

Title - The title bar - the very top of the browser - displays the title of the page. The title of a web page is also displayed in search engine result pages; in minimized window titles at the bottom of the screen; and in lists of bookmarks or favorites.


Top-level Domain (TLD)

In the Domain Name System (DNS), the highest level of the hierarchy after the root. In a domain name, that portion of the domain name that appears furthest to the right. For example, the "com" in logicalpages.com.

tracert - a TCP /IP utility which allows the user to determine the route packets take to reach a particular host. Trace route works by increasing the "time to live" value of each successive packet sent. The first packet has a TTL value of one, the second two, and so on. When a packet passes through a host, the host decrements the TTL value by one and forwards the packet to the next host. When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded. Customers are sometimes asked to perform this function to determine if there is a break in communications between themselves and a remote server such as Lunarpages' servers.

Transfer (Domain Names)

The process of changing the party who is listed as the domain name Registrant.  The term transfer is often defined differently by Internet Service Providers (ISPs), registrars, and customers. The most frequent types of transfers are: 1) Transferring your domain name registration to LogicalPages. 2) Transferring your LogicalPages registered domain name to another provider. 3) The process of transferring the domain name from one Registrant to another Registrant – also known as a Registrant Name Change Agreement. The party taking over the domain name is responsible for paying a new registration fee.

Traffic - the amount of activity over a communication system during a given period of time; "heavy traffic overloaded the trunk lines"; "traffic on the internet is lightest during the night"

Trojan (Trojan horse) - An apparently useful and innocent program containing additional hidden code which allows the unauthorized collection, exploitation, falsification, or destruction of data. Most commonly associated with viruses.



U

Upload - Transferring a file or files from the user's computer to a remote computer.

Uptime - strangely enough, the opposite of downtime. It is defined as being the time that an item of equipment is in service and operating.

URI - Uniform Resource Identifier - URIs have been known by many names: WWW addresses, Universal Document Identifiers, Universal Resource Identifiers, and finally the combination of Uniform Resource Locators (URL) and Names (URN). As far as HTTP is concerned, Uniform Resource Identifiers are simply formatted strings that identify - via name, location, or any other characteristic - a resource.


Universal Resource Locator (URL)

The global address of documents and other resources on the World Wide Web.

Uniform Resource Locator; an address that specifies the location of a file on the Internet (eg, http://www.fsu.edu/library).
Usability - Usability is the measure of how easy it is to use a website. A site would be considered usable if it meets certain criteria, which can include: having logical navigation, adherence to established conventions for the web, and providing an easy to use help section. Many other factors can come into play.

V


validation/validator - An automated tool to check that coding used to create web pages is valid. It is important that coding is valid as this can impact on the accessibility of pages. Assistive technology used by disabled users such as screen readers may have problems if coding is invalid. Search engines may also have difficulty indexing pages. Most web editing packages include HTML validators or checkers, alongside spell checkers. Online validators are also available, eg W3C HTML validator and Style Sheet Validator.

Virtual host - A computer which can be forced to respond to multiple IP addresses and provide various services (typically different Web services) on each. Each of these IP addresess (which usually each have their own hostname) operate as if they were separate hosts on separate machines, although they are really all the same host. Therefore, they are called "virtual" hosts. An example of virtual hosting is when an Internet Service Provider "hosts" World-Wide Web and other services for several customers on the same computer but gives the appearence that each of these services use separate servers.

Virus - A virus is a type of program that can replicate itself by making (possibly modified) copies of itself. The main criterion for classifying a piece of executable code as a virus is that it spreads itself by means of 'hosts'. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable disk. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with worms. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms.

Viruses can infect different types of hosts. The most common targets are executable files that contain application software or parts of the operating system. Viruses have also infected the executable boot sectors of floppy disks, script files of application programs, and documents that can contain macro scripts. Additionally, viruses can infect files in other ways than simply inserting a copy of their code into the code of the host program. For example, a virus can overwrite its host with the virus code, or it can use a trick to ensure that the virus program is executed when the user wants to execute the (unmodified) host program. Viruses have existed for many different operating systems, including MS-DOS, AmigaOS, and Mac OS; today, the majority of viruses run on Microsoft Windows.A legitimate application program that can copy itself as a side-effect of its normal function (e.g. backup software) is not considered a virus. Some programs that were apparently intended as viruses cannot reliably self-replicate, because the infection routine contain bugs. For example, a buggy virus can insert copies of itself into host programs, but these copies never get executed and are thus unable to spread the virus. Self-replicating programs that have very limited spreading capabilities because of bugs should not be considered legitimate viruses.

Visits - a complete session of accesses to a certain web server conducted by one person. A visit is concluded when the customer hasn't viewed any page for a certain period of time (60 seconds in most cases).

VOIP - (Voice over Internet Protocol) The technology used to transmit voice conversations over a data network using the Internet Protocol. Such data network may be the Internet or a corporate Intranet.

VPN - (virtual private network) A private network constructed across a public network such as the Internet. A VPN can be made secure, even though it is using existing Internet connections to carry data communication. Security measures involve encrypting data before sending it across the Internet and decrypting the data at the other end. An additional level of security can be added by encrypting the originating and receiving network address.
W3C - The W3C (short for World Wide Web Consortium) is the body that defines standards for many web related languages and technologies. They oversee development of standards for languages such as HTML and CSS . Their site can be found here: http://www.w3.org/

W


WAP - (Wireless Application Protocol) An open, global specification that empowers mobile users with wireless devices to easily access and interact with information and services instantly.

Web Server

Web server is a computer that stores web pages and delivers them on request to the web browsers of client computers.

Web space - An amount of data storage space used to host websites and files on the Internet, usually measured in Megabytes (MB).

WHOIS

WHOIS is a directory of domain name information. When you register a domain name, your postal address, email address and phone number are automatically published in the public WHOIS database. The Internet Corporation for Assigned Names and Numbers (ICANN), the nonprofit body responsible for accrediting domain name registrars, requires that this personal information be accurate and available for anybody to view on the Internet.

whois - Whois is a term referring to a domain name search or look-up feature for a database - typically for Top-Level Domain name registries. Information such as name availability can be found through a query or search using a whois protocol (standard). Most Top-Level Domain registries maintain their own whois database containing domain name contact information.


World Wide Web (WWW)

Think of the Web as a worldwide collection of text and multimedia files and other network services interconnected via a system of hypertext documents. Http (Hypertext Transfer Protocol) was created as a means for sharing data internationally, instantly, and inexpensively. With hypertext, a word or phrase can contain a link to other text. To achieve this, CERN developed a programming language called HTML, which allows you to easily link to other pages or network services on the Web.

WYSIWYG - (What You See Is What You Get) A graphical interface to a process which shows how the end-result will look as it is being produced, eg a WYSIWYG HTML editor generates HTML markup but displays the document as if viewed with a Web browser.

X

XFORMS - XForms is an XML format for the specification of user interfaces, specifically web forms. XForms was designed to be the next generation of HTML / XHTML forms, but is generic enough that it can also be used in a standalone manner to describe any user interface, and even perform simple and common data manipulation tasks.

XHTML - The next generation of HTML and is a hybrid between HTML and XML. XML was designed to describe data. HTML was designed to display data. XHTML is much stricter than HTML. Not all browers support XML so XHTML provides an intermediary soluton and can be interpreted by XML and HTML browsers. For further information see: http://www.w3c.org/MarkUp/

XML - Extensible Markup Language, a specification developed by the W3C. XML is a pared-down version of SGML, designed especially for Web documents. It allows designers to create their own customized tags, enabling the definition, transmission, validation, and interpretation of data between applications and between organizations.

XSLT - (eXtensible Stylesheet Language Transformations) A language used to transform XML documents into other documents. In Second Site, XSLT is used to transform XML documents into HTML tags. The XSLT standard is administered by the World Wide Web Consortium (W3C).
