In this video, I discuss HTTP protocol.
HTTP is an application protocol used for communication on world wide web
HTTP is a request-response protocol to access web resource like HTML files.
Client and server exchange hypertext message to communicate.
User use web browser to request a page from server. Web browser are the client applications.
Web Server runs as a background service and responds to the request made by the client.

HTTP originally developed to publish and retrieve HTML pages then it has been used for distributive and collaborative information system.
User typed URL having three components in it.
(1)The protocol or scheme
(2)The Server Name
(3)The requested File
It defines message types used by: the client to send request and the server to respond

The most widely used message types are:

GET: used by client to request
POST: used to upload data on server
PUT: used to upload data on server

HTTP Characteristics:
HTTP is a stateless protocol means the server does not save state or session information
HTTP mostly uses TCP protocol at transport layer which is connection-oriented
HTTP sends message in plain text, therefore it is not secure
HTTPS is the secure protocol as it uses Authentication and encryption
