What is the fundamental difference between Backend and Frontend?

Frontend is the interface part that the user sees and interacts with (HTML, CSS, JS). Backend is the logical part that runs on the server side, where data is processed and database operations are performed (PHP, Python, SQL).

Which hosting package is better for Backend performance?

For intensive backend operations, Virtual Server (VPS/VDS) or Cloud Hosting packages with dedicated CPU and RAM resources are recommended.

What does Full Stack Developer mean?

                //Security and authorization control
                if (!Auth::check()) {
                  return response()->json(['error' => 'Unauthorized'], 401);
                }
