When we want a front-end to communicate with backend, we need to establish connection between them.

2. Client will have to create a socket in its own process.

3. Client using its socket has to submit a request to server socket.

4. Sever socket should receive the request on existing client and shift’s the client to another new socket which has to be created freshly. This is done so that server main socket is free to receive request from another client(s).
