This is a frequently asked question in web developer interview questions for freshers. The essential HTTP request types in REST are as follows: GET - The GET method is used to retrieve data or resources from the server and allows read-only access to the data. POST - The POST method is used for creating a new resource. It is often used while uploading a file or submitting a completed web form. PUT - PUT is similar to POST, but it is used to update an existing resource by replacing its contents entirely.   PATCH - PATCH is also used to update an existing resource but unlike PUT, it modifies the existing resource.   DELETE - The DELETE request is used to delete the resource from the server.
