These resources could be HTML files, image files, query results, or anything else. A browser is works as an HTTP client because it sends requests to an HTTP server which is called Web server. The Web Server then sends responses back to the client. The standard and default port for HTTP servers to listen on is 80 but it can be changed to any other port like 8080 etc. There are three important things about HTTP of which you should be aware: HTTP is connectionless:  After a request is made, the client disconnects from the server and waits for a response.

The SGML is a programming language through which markup languages are developed and its HTML application is a markup of text which uses...
