The World wide Web is a network of information resources. A resource can be practically anything you like: an HTML page, a picture, a video clip, a sound file, a program……. Every resource on the web has an address know as a Universal Resource Location (URL). A URL consists of:
For example: http://www.ann.com/page.html This simply means that there is a file called homepage.html that is sitting on the machine www.ann.com which you can look at via the http protocol. The http scheme is the most common URL scheme and you use it to locate documents that sit somewhere on a web server. HTTP stands for Hypertext Transfer Protocol and it is designed to transfer hypertext documents over the Internet. In this example, www.ann.com is the domain name. The domain name simple translates the IP address of the machine into a more friendly format. You’re not going to remember some thing like 172.19.72.95 all that easily are you? The final part homepage.html is the name of the document. You’ll probably find that name of the document includes a path. |
