Question $2$:

$[/8]$

In the scenario described, there are two TCP clients that communicate with a TCP server using TCP sockets. The figure illustrates the Python code used to create a single listening socket on the server $($the listening socket itself is not depicted graphically$).$ Additionally, the code for the client sockets is also provided. The three sockets shown on the server were created because the server accepted connection requests through the listening socket$-$one connection from the client on the left and two connections from the client on the right.
