Atom - In web syndication, Atom is a standard XML format. Blogger will automatically create and publish an Atom Feed for you if you so choose.

Blogger, a coined word created by Pyra Labs, is a service that provides Web-based tools used by individuals to publish to the Web.  It is now also a word generally used to refer to someone who blogs. You may use Blogger to become a blogger.

The tool Blogger is a service to make weblog publishing easier. The user does not have to write any code or to worry about installing server software or scripts. But nevertheless the user can influence the design of his blog freely.

Blogger allows for the hosting of the blogs on its own Blogspot or on the server of the blogger's choosing (via FTP or SFTP). While most of the web browsers are supported, Mozilla Firefox is used internally for all Blogger staffs.  Blogger advises its users, especially AOL users, to switch to Mozilla Firefox in order to have the best possible experience using Blogger.

Blogosphere - (alternate: blogsphere) is the collective term encompassing all weblogs. Weblogs are heavily interconnected; bloggers read other blogs, link to them, and reference them in their own writing. Because of this, the interconnected blogs have grown their own culture. Sites such as Technorati, Blog Street and Truth Laid Bear track the interconnections between them.

Feed - Feed also refers to RSS or Atom feeds used by news aggregators.

Firefox! - Mozilla Firefox (originally known as Phoenix and briefly as Mozilla Firebird) is a free cross-platform web browser developed by the Mozilla Foundation and hundreds of volunteers. Before its 1.0 release on November 9, 2004, Firefox had already garnered a great deal of acclaim from numerous media outlets, including Forbes and the Wall Street Journal. With over 5 million downloads in the first 12 days of its release and over 22 million in 12 weeks, Firefox 1.0 is one of the most-used free and open source applications, especially among home users.

With Firefox, the Mozilla Foundation aims to develop a small, fast, simple, and highly extensible web browser (separate from the larger Mozilla Suite). Firefox has become the main focus of Mozilla development along with the Mozilla Thunderbird e-mail client, and it has replaced the Mozilla Suite as the official browser release of the Mozilla Foundation.

Host - In informatics, host is synonymous with server. A host or server is where the code and content of a web site physically live.
The word host can also be used to describe the ISP or company that provides the hardware and connectivity to a website.

HTTP - HTTP (for HyperText Transfer Protocol) is the primary method used to convey information on the World Wide Web. The original purpose was to provide a way to publish and receive HTML pages.

Hyperlink (link) - A hyperlink, or simply a link, is a reference in a hypertext document to another document or other resource. As such it would be similar to a citation in literature. However, combined with a data network and suitable access protocol, it can be used to fetch the resource referenced. This can then be saved, viewed, or displayed as part of the referencing document.

RSS- Really Simple Syndication, a family of XML based web-content distribution and republication (Web syndication) protocols primarily used by news sites and weblogs (blogs).

• the Rich Site Summary is also known as RSS 0.91, 0.92 and RSS 2.x (although many weblog feeds are full-text, not summaries)
• the RDF Site Summary is based on Netscape's short-lived RSS 0.90, which used the W3C Resource Description Framework Standard; this is also known as RSS 1.x
• Sometimes, by casual (though incorrect) use, alternative syndication protocols, such as Atom.

Server - The term is now also used to mean the physical computer on which the software runs. Originally server software would be located on a mainframe computer or minicomputer. These have largely been replaced by computers built using a more robust version of the microprocessor technology than is used in personal computers, and the term "server" was adopted to describe microprocessor-based machines designed for this purpose.  If you are not a technical person, a server is just like your computer, but designed to handle more traffic. A server will have more memory, more processors and software designed specifically for the business of "serving" on the Internet or within a network.

URL - A Uniform Resource Locator, URL (either pronounced as "earl" or spelled out), or Web address, is a standardized address for some resource (such as a document or image) on the Internet (or elsewhere). First created by Tim Berners-Lee for use on the World Wide Web, the currently used forms are detailed by IETF standard RFC 2396.

The URL was a fundamental innovation in the history of the Internet. The syntax is designed to be generic, extensible, and able to express addresses in any character set using a limited subset of ASCII characters (for instance, whitespace is never used in a URL). URLs are classified by the "scheme" which typically identifies the network protocol used to retrieve the resource over a computer network.

W3C - The World Wide Web Consortium (W3C) is a consortium that produces standards-"recommendations," as they call them-for the World Wide Web. The Consortium is headed by Tim Berners-Lee, the original creator of URL (Uniform Resource Locator), HTTP (HyperText Transfer Protocol) and HTML (HyperText Markup Language), the principal technologies that form the basis of the Web.

Web Site- A website, Web site or WWW site (often shortened to just site) is a collection of webpages, that is, HTML/XHTML documents accessible via HTTP on the Internet; all publicly accessible websites in existence comprise the World Wide Web. The pages of a website will be accessed from a common root URL, the homepage, and usually reside on the same physical server. The URLs of the pages organize them into a hierarchy, although the hyperlinks between them control how the reader perceives the overall structure and how the traffic flows between the different parts of the site.

Web Syndication - In web syndication, web feeds make a portion of a web site available to other sites.

WWW - The World Wide Web "WWW", or simply "Web"  is an information space in which the items of interest, referred to as resources, are identified by global identifiers called Uniform Resource Identifiers (URI).

XML - The Extensible Markup Language (XML) is a W3C recommendation for creating special-purpose markup languages. It is a simplified subset of SGML, capable of describing many different kinds of data. Its primary purpose is to facilitate the sharing of structured text and information across the Internet. Languages based on XML (for example, RDF, RSS, MathML, XSIL and SVG) are themselves described in a formal way, allowing programs to modify and validate documents in these languages without prior knowledge of their form.

Portions of these definitions come from the Wikipedia, a free on-line encyclopedia that anyone can edit. (Within reason, if you write trash, your trash will be taken out!)   The parts that seem less technical and easier to read were added by the author.
