(b) A client requires to send a message to a server and the server will echo the message that been received back to the client, where both are connected through Ethernet network via TCP Socket as shown in Figure Q.4. Client Port 8888 Port 8888 Server Host: 192.168.12.1 Host: 192.168.12.6 Figure Q.4: Client and server connection using TCP Your program should have the following features: a) Socket connection between client and server with specific host address and port number b) Client is able to send messages c) Server will echo to the client d) Client will display the result e) Close the socket connection when server received message "Exit" f) Able to detect and display the errors (Note: Marks will be given based on working codes and coding style) (1) Write a coding for client site to implement the task. (8 marks) (ii) Write a coding for server site to implement the task. (8 marks) (ii) Assuming client and server are in different devicelentity. If the client is not able to send messages to the server, explain what might happen to the network. (4 marks)
