How it Works

Step 1:  In any Client/Server Application, we need to run the server before the client, because the server keeps waiting for the client to be connected.
Step 2: Server keeps listening for the client on an assigned IP & Port
Step 3: For establishing connection client must know the IP & Port of the server.
Step 4: 

 

When we start Client Application, It creates a connection to the server.

Step 5: After the Successful connection Client & Server Applications can send & receive messages.
