Identify the correct order in which a server process must invoke the function…

Correct order: bind, listen, accept, recv

• bind: Associate the socket with a local address and port so the server has an endpoint to accept connections on.

• listen: Mark the bound socket as passive and specify a backlog; this tells the OS to queue incoming connection requests.

• accept: Remove the next pending connection from the queue and return a new connected socket specific to that client.

• recv: Read data from the connected socket returned by accept (not from the listening socket).

Key warning: accept requires a listening socket, and recv requires a connected socket. Calling these functions in the wrong order will cause errors or incorrect behavior.
