A Web server is a program that, using the client or server model and the World Wide Web’s Hypertext Transfer Protocol (HTTP), serves the files that form Web pages to Web. Every computer on the Internet that contains a Web site must have a Web server program. Other Web servers include Novell’s Web Server for users of its NetWare operating system and IBM’s family of Lotus Domino servers, primarily for IBM’s OS/390 and AS/400 customers.
Web servers have a vital role on the Internet. The Server machine hosts the web site while the server program helps deliver the web pages and their associated files like images and flash movies. Web servers often come as part of a larger package of Internet.
The process of loading a web site. The server software now takes up and hunts for the requested web page on the hard disk. The job of a web server ends once it processes the request from a browser and sends the required information.
Though the request and response might seem time consuming, it actually happens very fast have you ever waited more than a minute for a web site to load. And it’s all because of the HyperText Transfer Protocol (HTTP) which is a set of rules developed by the “big lads” to facilitate the transfer of data over the internet.
