- Cascading Style Sheets ( CSS )
-
Cascading Style Sheets (CSS) is a language related to HTML that the browser can read to impart visual styles to HTML pages. In web development, you might hear that best practice is to separate content from visual presentation. This allows your page to be very flexible in how it appears. You can have the same information that is presented for a web browser on a computer, a cellular telephone, a kiosk, an Internet-equipped television, or who knows what. The only thing that would have to change is the style sheet that tells the device how to show the same information differently (suited to each medium). 158 -

A web protocol much like HTTP (Hypertext Transfer Protocol) that moves information around the Web. The difference between the two is that HTTP opens a connection between the server and the browser, downloads the information (like a web page), and then closes the connection so that other browsers can access the server. FTP creates a connection and then leaves that connection open for a time to allow files to move to and from the server. This forces the server to focus on fewer dedicated connections at one time than an HTTP server. 222 -
