Which HTTP method is primarily used to access and retrieve data from a server?

The HTTP method primarily used to access and retrieve data from a server is the GET method. It is designed specifically for this purpose, allowing clients to send requests to a server to fetch data without altering any state on the server.

When a GET request is made, it retrieves information from the server, which can then be displayed to the user or used in further processing. GET requests are safe and idempotent, meaning they do not change server state and can be repeated without causing any additional effects.

In contrast, POST is used for creating resources on the server, PUT is intended for updating existing resources, and DELETE is specifically for removing resources. Each of these methods serves a distinct purpose in the RESTful architecture, making GET the only suitable choice when the goal is to access and retrieve data.
