The servers are located around the world, and they store information that is organized into pages. The client connects to the server via a modem or an ethernet connection. The client software, or the browser, sends a request to the server and the server responds by downloading the information to your computer. Each time you click on a hypertext link, you are sending a request to a server. The Web allows people all over the world to use standard methods for storing, finding and transferring information.
Web documents are accessible using software called a browser.
Each browser recognizes the standard Web formats. This makes the Web an easily accessible form of communication regardless of the platform you use. It is the browser's job to interpret the code. Each browser interprets this code in its own way, causing the same web page to display differently through different browsers. Netscape Navigator and Internet Explorer are currently the most popular browsers with the most capabilities for viewing graphics and movies and hearing sounds.
