referrer - A referrer is the URL of the page from which a user accesses another page. For example, if you have two pages,example.com/page1.html and example.com/page2.html, and someone accesses example.com/page2.html from a link on example.com/page1.html, the referrer would be
example.com/page1.html. The referrer URL is sent by most browsers as part of a request for a
page. If a user makes a direct request for a page (for example, typing example.com/page2.html into the address bar), there will be no referrer information sent.
Registrar - A registrar is a company that handles domain name registrations. They sell domains and allow their customers to manage domains they have purchased.

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."

Script - A program written in a general-purpose programming language. Such languages are typically interpreted and less comprehensive than full-blown compiled languages.

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.

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.

Sendmail - An SMTP-based message transfer agent ( MTA ) that runs under Unix. Developed at the University of California at Berkeley by Eric Allman in 1981, sendmail stores and forwards more mail than any other MTA on the Internet. In 1998, Allman commercialized the product by forming Sendmail, Inc. (www.sendmail.com), which offers a GUI interface for modifying the configuration file instead of dealing directly with more than a thousand lines of text. Sendmail, Inc. also offers a Windows NT/2000 version that includes the POP mail server and message store. Examples of mail clients developed for sendmail in the Unix world are elm, pine, mush and mailx.

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.

Squirrel Mail is written in PHP4 and it includes built-in pure PHP support for the IMAP and SMTP protocols. All pages render in pure HTML

SSI – Server Side Includes are directives that are placed in HTML pages, and evaluated on the server while the pages are being served. They let you add dynamically generated content to an existing HTML page, without having to serve the entire page via a CGI program, or other dynamic technology. SSI page can be identified by .shtml file extension.
