4. What is HTTP protocol? Define HTTP Request and Response.[2+3]

5 marks | Asked in 2076(new)

HTTP is a TCP/IP based communication protocol, that is used to deliver data (HTML files, image files, query results, etc.) on the World Wide Web. The default port is TCP 80, but other ports can be used as well. It provides a standardized way for computers to communicate with each other. HTTP specification specifies how clients' request data will be constructed and sent to the server, and how the servers respond to these requests.

HTTP Architecture

HTTP works as a request-response protocol between a client and server. For example: A client (browser) sends an HTTP request to the server; then the server returns a response to the client. The response contains status information about the request and may also contain the requested content.



  • HTTP Request: HTTP client sends an HTTP Request to the HTTP Server according to the HTTP standard, specifying the information the client like to retrieve from the Hypertext Transfer Protocol (HTTP) Server.
  • HTTP Response: Once the HTTP Request arrived at the HTTP server, it will process the request and creates an HTTP Response message. The HTTP response message may contain the resource the HTTP Client requested or information why the HTTP request failed.
