accept() function in C for network programming

Why does accept() function call initialize a new socket instead of using the same socket we made using socket() function call. I am working on TCP client-server program.

int welcomeSocket, newSocket;
welcomeSocket = socket(PF_INET, SOCK_STREAM, 0); //socket initialized..

// initializing different structure values..

bind(welcomeSocket, (struct sockaddr *) &serverAddr, sizeof(serverAddr));
listen(welcomeSocket,5);

/*---- Accept call creates a new socket for the incoming connection ----*/
addr_size = sizeof serverStorage;
newSocket = accept(welcomeSocket, (struct sockaddr *) &serverStorage,&addr_size);
send();

// why accept makes a new socket?????

Because the original socket you created needs to stay around, so you can accept multiple simultaneous connections.

The socket returned by accept is not your "listening socket", it is a socket that on the other end has a communicating peer connected.
