Can you name the main categories of response codes used in communication protocols?

The main categories of response codes used in communication protocols (e.g., HTTP) are divided into five classes:

• 1xx (Informational) — indicate that the request has been received and the process is continuing.
• 2xx (Success) — the request was successfully processed (e.g., 200 OK).
• 3xx (Redirection) — further action is needed to complete the request (e.g., 301 Moved Permanently).
• 4xx (Client Error) — there was an error on the client side (e.g., 404 Not Found).
• 5xx (Server Error) — there was an error on the server side (e.g., 500 Internal Server Error).

These categories help understand the result of the request processing and determine further actions.
