📌 What is HTTP?

HTTP (HyperText Transfer Protocol) is a communication protocol used by browsers and servers to exchange information over the internet.

📌 What is HTTP GET Method?

The GET method requests data from a server. It sends parameters in the URL.

Example:

https://api.example.com/users?id=101

Features of GET:

  • Data visible in URL
  • Limited data size
  • Cacheable
  • Not secure for sensitive data

📌 What is HTTP POST Method?

The POST method sends data to the server inside the request body.

Features of POST:

  • Data hidden from URL
  • High data size allowed
  • More secure
  • Used for creating records
