 A

Absolute URL: The full Internet address of a page or other World Wide Web resource. The absolute URL includes a protocol, such as “http,” network location, and optional path and file name. Example, http://example.microsoft.com/ is an absolute URL.

Accessibility: The quality of a system incorporating hardware or software that makes it usable by people with one or more physical disabilities, such as restricted mobility, blindness, or deafness.

Active Data Objects (ADO): Components that enable client applications to access and manipulate data in a file-or server-based database through a provider.

Active hyperlink: A hyperlink that is currently selected in a Web browser. Some Web browsers indicate the active hyperlink by changing its color.

Active Server Page (ASP): A document that contains embedded server-side scripting. ASP-compatible Web servers can execute these scripts. On the client side, an ASP is a standard HTML web browser.

ActiveX: A set of technologies that enables software components to interact with one another in a networked environment, regardless of the language in which the components were created. ActiveX is used primarily to develop interactive content for the World Wide Web, although it can be used in desktop applications and other programs.

ActiveX Controls: Reusable software components that incorporate ActiveX technology. ActiveX controls can be embedded in Web pages to produce animations,  multimedia effects, interactive objects, and sophisticated applications. They can be written in a variety of programming languages, including C, C++, and Visual Basic.

Algorithms: Search algorithm is, in short, the incredibly complex mathematical formula that a search engine uses to "rank" web sites for keywords. Based on a huge number of variables and calculations, algorithms are among the most closely-guarded secrets on the internet. Why? Imagine if they were leaked - suddenly the less-than-honest would have a very specific guideline to follow in climbing to the top of search results in a less-than-organic way, ruining the quality of Google's search results and their entire competitive advantage with it.



Animated GIF: A file containing a series of GIF (Graphics Interchange Format) graphics that are displayed in rapid sequence in a Web browser, giving the appearance of a moving picture.

Anonymous FTP: The ability to access a remote computer system on which one does not have an account, via the Internet's File Transfer Protocol (FTP). Users have restricted access rights with anonymous FTP and usually can only list, view, or copy files to or from a public directory on the remote system. Many FTP sites do not permit anonymous FTP access in order to maintain security.


Article: A message or posting in a discussion group or an Internet newsgroup. An article can be a response to a previous article.

ASCII: (American Standard Code for Information Interchange) A coding scheme using 7 or 8 bits that assigns numeric values to up to 256 characters, including letters, numerals, punctuation marks, control characters, and other symbols.

 Bookmark: A named location on a Web page that can be the target of a hyperlink. A bookmark can be applied to a string of characters or exist on a page separately from any text. Bookmarks allow authors to link to a specific section of a target page. In a URL, a bookmark that is preceded by a pound sign (#). Also called an anchor.

Boolean: Advanced searching techniques, named after British mathematician George Boole.

Bot or Bots: See also crawlers

Breadcrumbs: Breadcrumbs show you where you are, like "You are here" indicators; however, breadcrumbs only trace the path you took from the Home page. See also navigation bars

 C

Cache: An internal storage area within the browser that saves web pages recently visited so they reload more quickly.




 Cascading Style Sheet (CSS): An HTML specification developed by the World Wide Web Consortium that allows authors of Web pages to attach style sheets to HTML documents. Style sheets can include typographical information on how the page should appear, such as the font of the text in the page. CSS also directs the way in which the style sheets of the HTML document and the user's style will blend.

Cell padding: The space between the contents and inside edges of a table cell.

Cell spacing: The amount of space between cells in a table. Cell spacing is the thickness, in pixels, of the walls surrounding each cell.

 CGI (Common Gateway Interface): A standard method of extending Web server functionality by executing programs or scripts on a Web server in response to Web browser requests. A common use of CGI is in form processing, where the Web browser sends form data to a CGI script on the server, the script integrates the data with a database, and sends back the results as a Web page. Use of CGI can make a Web page much more dynamic and add interactivity for the user.

Chat: Real time one-to-one or group conversation, with discussion in typed form.

 Crawlers: Googlebot, for example, is a search engine crawler. Googlebot periodically traverses the web in record time, indexing content, links - everything contained in page source code - and storing it in Google's search index. Then, when a user visits Google and enters a search phrase, the index, filtered by the algorithm, is what the user gets. Please note: there is some delay in this process since the results you're getting are from the index and not the live web.



 D

Database: A file containing records of information that are organized and presented to serve a specific purpose, such as the facilitation of searching, sorting, and recombination of data. Databases can be published on the World Wide Web to let site visitors look up information in records or add new information to the database.

Default settings: Settings or instructions that a software application assumes unless the user changes the preferences.
Demo software: Sample software with a temporary usage time period programmed in, so that if you don't pay for a license it will cease to function.

Digital versatile discs (DVD): Discs that offer the ability to play full-length feature films on the computer. DVDs have approximately 26 times the capacity of a CD.

 Directories: Listings of web sites selected and classified into “subject tree” hierarchies by human editors. When webmasters realized just how much power inbound links have in determining search rankings they quickly set out to do two things: 1) get inbound links and 2) set up web sites where other webmasters could achieve inbound links (meaning big traffíc revenues for the site). Hence the directory farms you'll find. Link building has been a priority on the líst of any SEO-savvy webmaster for years, and as a result "quick fix" directories that allow streamlined listing submissions get a ton of traffíc.


Discussion group: Visitors submit topics or responses by entering and then submitting text in a form. Visitors can search the group using a search form, or access articles using a table of contents.

Distance learning: Educational programs conducted without the student and teacher being in the same space at the same time.

Form field: A data-entry field on a page. A site visitor supplies information in a field either by typing text or by selecting a field.

Form handler: A program on a server that is executed when a site visitor submits a form.



 Frame: An area of a Web browser window defined by a frames page. A frame appears in a Web browser as one of a number of different areas in which pages can be displayed. A frame may be scrollable and resizable, and may have a border. You display a page in a frame by creating a hyperlink to the page and specifying the frame as part of the hyperlink.

Frameset : A page that divides a Web browser's window into different areas called frames that can independently display several Web pages.From an SEO standpoint the use of frames for your layout is not recommended. Since frames do not use links in the same way, and since links may point to one frame from another, they may cause serious problems for crawlers. See also frame.

Host name: See networks.

Hotspot: A graphically defined area in a graphic or picture containing a hyperlink. A graphic with hotspots is called an image map. Hotspots are invisible in Web browsers. Site visitors can tell that a hotspot is present because the mouse pointer changes appearance when the mouse is moved over the graphic. See also image map.

Hover Button: An animated button in the navigation bar on a Web page that is activated when the mouse pointer is moved over the button or when the button is clicked. See also navigation bar.

 Hypertext markup language (HTML): The standard markup language used for documents on the World Wide Web. The coding system that is used to make web pages. Every web page contains HTML tags that tell browsers where and how to present the text, graphics, links, and other components. Most Web browsers, notably Microsoft Internet Explorer, Netscape Navigator, Firefox and Opera, recognize HTML tags beyond those included in the present standard.

Hypertext transfer protocol: HTTP appears at the beginning of most Internet addresses. It is the set of rules and procedures that allows web sites to work for any visitor, regardless of their type of computer or network. The Internet protocol that enables Web browsers to retrieve information from World Wide Web servers.

Hyperlink: A pointer from text, from a picture or a graphic, or from an image map to a page or file on the World Wide Web. On the World Wide Web, hyperlinks are the primary way to navigate between pages and among Web sites. Also called link.

Hypertext: Originally, any textual information on a computer containing jumps to other information. The hypertext jumps are called hyperlinks. On the World Wide Web, hypertext is the primary way to navigate between pages and among Web sites. Hypertext on Web pages has been expanded to include hyperlinks from text, from a picture or a graphic, and from image maps.




 I

 Image map: A graphic containing one or more invisible regions, called hotspots, which are associated hyperlinks. Typically, an image map gives site visitors visual cues abont the information made available by clicking each part of a picture or graphic.

Currently, the Internet offers a range of services to users, such as e-mail, the World Wide Web, FTP, Usenet newsgroups, Gopher, IRC, telnet, and others.

 Internet service providers (ISP): ISPs provide individuals and businesses with access to the Internet through dial-up connections, as well as, DHL and broadband services.

Intranet: A network designed for information processing within a company or organization. Its uses include such services as document and software distribution, access to databases, and training. An intranet is so called because it usually employs applications associated with the Internet, such as Web pages, Web browsers, FTP sites, email, newsgroups, and mailing lists, accessible only to those within the organization.

IP (Internet Protocol): Internet software that divides data into packets for transmission over the Internet. Computers must run IP to communicate across the Internet. See also TCP

IP address (Internet Protocol address): The standard way of identifying a computer that is connected to the Internet, much the way a telephone number identifies a telephone on a telephone network.

 Java applet: A Java class that is loaded and run by an already-running Java application such as a Web browser. Java applets can be downloaded and executed by a Web browser capable of interpreting Java, such as Microsoft Internet Explorer or Netscape Navigator. Java applets are frequently used to add multimedia effects and interactivity to Web pages, such as video displays, animations, calculators, real-time clocks, and interactive games. Applets can be activated automatically when the page containing them is displayed in a Web browser, or they may require some action on the part of the site visitor, such as clicking an element on the page.

 JavaScript: A scripting language developed by Netscape Communications and Sun Microsystems, Inc. Compared to Java, JavaScript is limited in performance because it is not compiled before execution. Basic online applications and functions can be added to Web pages with JavaScript, but
the number and complexity of available application programming interface functions are fewer than those available with Java. JavaScript code, which is included in a Web page along with the HTML code, is generally considered easier to write than Java, especially for novice programmers. A JavaScript-compliant Web browser, such as Microsoft Internet Explorer or Netscape Navigator, is required to interpret JavaScript code.

JPEG (Joint Photographic Experts Groups): A format for the storage and display of photographs and images created outside the computer environment and then digitized. JPEG graphics apply a user-specified compression scheme that can significantly reduce the large file sizes usually associated with photo-realistic color graphics.

RAS: The raster graphics file format developed by Sun Microsystems.

Real time: A way of describing synchronous communication, or technologies that enable people to be in direct contact, as opposed to asynchronous methods, such as e-mail.

Registration Form Handler: a form handler allows site visitors to automatically register themselves for access to a service implemented as a Web site. The Registration form handler adds the site visitor to an authentication database, then gathers optional information from the form and stores it in one of many supported formats.

Relative URL: The Internet address of a page or other World Wide Web resource relative to the Internet address of the current page. A relative URL gives the path from the current page to the destination page or resource. A relative URL can include a protocol.

Resample: The changing of the pixel dimensions (and therefore physical file size) of a picture or a graphic. Graphics can be resampled down (the number of pixels is decreased) or resampled up (the number of pixels is increased). When you resample a graphic down, pixel information is deleted from the graphic. When you resample a graphic up, new pixel information is created based on matching color values of the existing pixels. Resampling a graphic down and then resampling it up to its original resolution will cause the quality of the graphic to deteriorate considerably

Rich Site Summary (RSS): RSS, which stands for Really Simple Syndication, is a file format that acilitates the sharing and syndication of web site content. Nearly every major news operation, blog, and high -traffic specialty site offers its frequently updated content as a feed.

RTF (Rich Text Format): A method of encoding text formatting and document structure using the ASCII character set. By convention, RTF files have an .rtf file name extension.






 S

 Save Results form handler: A form handler that gathers information from a form and stores it in one of a number of formats or sends the information to an e-mail address. When a site visitor submits the form, the Save results form handler appends the form information to a file on the server in the format you specify.

Script: A type of computer code that can be directly executed by a program that understands the language in which the script is written.

Scrolling text box: A labeled, multiple-line form field in which site visitors can type one or more lines of text.

 Search engine: An automated system that uses “spiders” to automatically search the web, copying information into huge databases and then enabling users to find relevant web content by entering keyword queries.

 Search Engine Optimization (SEO): This one is open to interpretation. It is quite often used to encapsulate a huge amount of different tactics. On-site optimization, off-site optimization (link building, etc) and many other techniques all feasibly fall under the SEO blanket. However, there is an obvious difference between optimizing a page's code to be clean and search friendly and writing link bait that will be popular and get linked to.

 Secure sockets layer (SSL): SSL is the technical name for the secure encryption method most often provided on the web, enabling transmission of private information such as credit card numbers in a secure environment.

 Server: A computer that offers services on a network. On the World Wide Web, a server is a computer that runs the Web server software that responds to HTTP protocol requests. See also host.

Software: Electronic programming instructions for operating systems, and applications such as word processing and spreadsheets.

Sp@mming: Basically, any unnatural effort to bring a page higher in search results. What constitutes sp@m is open to some interpretation, but the only interpretation you need to worry about is that of the major search engines. If Google, for example, considers a technique "spammy" you'd be wise to cease at once.


Streaming: A technique for transferring data as a continuous stream, enabling transmission of multimedia content.

Structured Query Language (SQL): A database query and programming language widely used for accessing, querying, updating, and managing data in relational database systems.
