What is the purpose of a GET request in HTTP?

• A. To signal a need to retrieve information from the server
• B. To create a new resource on the server
• C. To update an existing resource on the server
• D. To delete a resource from the server

Answer: (A)

The purpose of a GET request in HTTP is primarily to signal a need to retrieve information from the server. When a client (such as a web browser) sends a GET request, it is asking the server to send back specific data or content, such as web pages, images, or other types of files. The GET request is one of the most common methods used in HTTP and is typically used to obtain data without modifying the resource on the server. GET requests are designed to be safe and idempotent, meaning they can be made multiple times without affecting the server's state – they simply retrieve the current state of the resource. This allows clients to request data as needed without causing any changes to the underlying information stored on the server. In contrast, other methods like POST, PUT, and DELETE are intended for creating, updating, or removing resources from the server, respectively. Hence, they do not apply to the purpose of retrieving data, which is the sole function of the GET request.
