Explanation: Server Code: Setup: Creates a socket using socket(). Configures server address serverAddr with AF_INET (IPv4), INADDR_ANY (binds to all available interfaces), and PORT. Binds the socket to the address using bind(). Listens for incoming connections with listen(). Handling Clients: Uses accept() to accept incoming client connections. Spawns a …
