Program Plan Intro

HTTP Protocol:

  • Hypertext Transfer Protocol (HTTP) is one of the high-level protocols of the World Wide Web for transmitting documents.
    •  High-level protocol defines the format of message for communication between the devices.
  • It is an application-level protocol used for communication between the client and server in various formats such as text, images, and videos.
  • Client sends an http request to the server, and the server performs the function and returns the response to the client.
  • Server does not remember the previous request, so HTTP is a stateless protocol.
    •  Stateless protocol means each request is independent of the previous request and requires a separate TCP connection.
  • To open a web page, enter “http://” before the web address to make the browser to communicate over HTTP.
    •  For example, to open a browser, enter “http://www.google.com” .
