Algorithm Steps:

Server:

Step 1: Start the program

Step 2: Create a socket with address family AF_INET type SOCK_STREAM and default protocol.

Step 3: Initialize a socket and set its attributes.

Step 4: Bind the server to the socket using bind function.

Step 5: wait for the client request, on request establish a connection using accept function.

Step 6: fork a child process, perform step 7-10 for each process.

Step 7: Read the message from the client thro the connection.

Step 8: Display the client I message.

Step 9: send an acknowledgement message to the client .

Step 10: Exit the child process.

Step 11: close the connection and go to step 5.

Client:

Step 1: start.

Step 2: create a socket with address family.

Step 3: Initialize the socket and set its attributes set the required port no.

Step 4: Type AF_INET socket with default protocol.

Step 5: Connect to server using connect function to initiate the request.

Step 6: Receive the acknowledgement from the server.

Step 7: stop.
