COMPUTER TERMS PART 5

SEO "Search Engine Optimization." Just about every Webmaster wants his or her site to appear in the top listings of all the major search engines. Say, for example, that John runs an online shoe store. He wants his site to show up in the top few listings when someone searches for “basketball shoes." Then he gets more leads from search engines, which means more traffic, more sales, and more money. The problem is that there are thousands of other shoe sites, whose Webmasters are hoping for the same thing. That's where search engine optimization, or SEO, comes in.

SOCIAL MEDIA Social media is a collection of Internet-based communities that allow users to interact with each other online. This includes web forums, wikis, and user-generated content websites. However, the term is most often used to describe popular social networking websites, which include the following:

STREAMING Data streaming, commonly seen in the forms of audio and video streaming, is when a multimedia file can be played back without being completely downloaded first. Most files, like shareware and software updates that you download off the Internet, are not streaming data. However, certain audio and video files like Real Audio and QuickTime documents can be streaming files, meaning you can watch a video or listen to a sound file while it's being downloaded to your computer. With a fast Internet connection, you can actually stream live audio or video to your computer.

TROLL "Internet trolls" are real and cause real problems. In computing, the term "troll" refers to a person who posts offensive, incendiary, or off topic comments online. These comments may appear in Web forums, on Facebook walls, after news articles or blog entries, or in online chat rooms. Trolls stir up emotions from other commenters, creating unnecessary arguments for the sake of amusement.

WAN "Wide Area Network." It is similar to a Local Area Network (LAN), but it's a lot bigger. Unlike LANs, WANs are not limited to a single location. Many wide area networks span long distances through telephone lines, fiber-optic cables, or satellite links. They can also be composed of smaller LANs that are interconnected. The Internet could be described as the biggest WAN in the world.

WEB 2.0 Web 2.0 is term that was introduced in 2004 and refers to the second generation of the World Wide Web. Like software, the new generation of the Web includes new features that were not available in the past. However, Web 2.0 does not refer to a specific version of the Web, but rather a series of technological improvements. Some examples of features considered to be part of Web 2.0 are listed below: Blogs - also known as Web logs, these allow users to post thoughts and updates about their life on the Web. Wikis - sites like Wikipedia and others enable users from around the world to add and update online content. Social networking - sites like Facebook and MySpace allow users to build and customize their own profile. Web applications - new applications make it possible to run programs directly in a Web browser.

WEB DESIGN Web design is the process of creating websites. It encompasses several different aspects, including webpage layout, content production, and graphic design. While the terms web design and web development are often used interchangeably, web design is technically a subset of the broader category of web development. Websites are created using a markup language called HTML. Web designers build webpages using HTML tags that define the content and metadata of each page. The layout and appearance of the elements within a webpage are typically defined using CSS, or cascading style sheets. Therefore, most websites include a combination of HTML and CSS that defines how each page will appear in a browser.

CSS "Cascading Style Sheet" Cascading style sheets are used to format the layout of Web pages. They can be used to define text styles, table sizes, and other aspects of Web pages that previously could only be defined in a page's HTML. CSS helps Web developers create a uniform look across several pages of a Web site. Instead of defining the style of each table and each block of text within a page's HTML, commonly used styles need to be defined only once in a CSS document.

WEBMASTER The webmaster is the person in charge of maintaining a Web site. The jobs of a webmaster include writing HTML for Web pages, organizing the Web site's structure, responding to s about the Web site, and keeping the site up-to-date.

WIKI A wiki is a Web site that allows users to add and update content on the site using their own Web browser. This is made possible by Wiki software that runs on the Web server. Wikis end up being created mainly by a collaborative effort of the site visitors. A great example of a large wiki is the Wikipedia, a free encyclopedia in many languages that anyone can edit. The term "wiki" comes from the Hawaiian phrase, "wiki wiki," which means "super fast." I guess if you have thousands of users adding content to a Web site on a regular basis, the site could grow "super fast."

WORDPRESS WordPress is a free software used to build websites. Its ease of use and unique blogging features have helped it become the most popular blogging tool on the web. WordPress provides a web-based user interface for designing, publishing, and updating websites. Instead of writing HTML, you can simply choose one of many different website templates or "themes" that has a design you like. You can then modify the layout and build a custom navigation bar. Once the site layout is complete, you can use WordPress' online interface to create individual pages. Each page may include formatted text, links, images, and other media. You can publish completed webpages or blogs by simply clicking the Publish button.
