Can you give examples of responses that a server might send after processing a request?

After processing a request, the server may send different types of responses depending on the result and protocol. Here are some examples:

• 200 OK — the request was successfully processed, and the server returns data (e.g., JSON with information).
• 201 Created — the resource was successfully created (e.g., after a POST request).
• 400 Bad Request — client error, such as an invalid request format.
• 401 Unauthorized — authentication is required.
• 404 Not Found — the requested resource was not found.
• 500 Internal Server Error — an error on the server side.

Example of a JSON response for a successful request:

{
  "status": "success",
  "data": {
    "id": 123,
    "name": "Example"
  }
}

Such responses help the client understand the result of the operation and handle the data correctly.
