HTTP stands for Hypertext Transfer Protocol. HTTP defines a set of request methods to indicate the desired action to be performed for a given resource.

HTTP Methods:

1. GET:
The GET method requests a representation of the specified resource. Requests using GET should only retrieve data.

2. HEAD:
The HEAD method asks for a response identical to that of a GET request, but without the response body.

3. POST:
The POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

4. PUT:

The PUT method replaces all current representations of the target resource with the request payload.

5. DELETE:
The DELETE method deletes the specified resource.

6. OPTIONS:
The OPTIONS method is used to describe the communication options for the target resource.
