TCP-Socket-Client-Server

This project involves the development of a TCP (Transmission Control Protocol) communication system using Java, consisting of two primary components: a TCP Server and a TCP Client. The system is designed for encoding and transmitting messages between a server and a client over a network.

TCP Server:

The TCP Server is the backbone of this system, responsible for several key functions:

• Listening for Incoming Connections: The server continuously monitors for incoming client connections, ready to receive messages.
• Message Encoding: Upon receiving a message from a client, the server encodes it by shifting each character by one position in the ASCII table. This simple encoding mechanism transforms the message before it is sent back.
• Response to Client: After encoding the message, the server sends it back to the client. This two-way communication demonstrates the server's ability to both receive and transmit data.

TCP Client:

The TCP Client interacts with the TCP Server, performing the following operations:

• Connecting to the Server: The client establishes a connection with the server using the same port number, ensuring a successful link for communication.
• User Input Transmission: The client allows users to input a message. This message is sent to the server when the user presses ‘enter’.
• Receiving Encoded Message: After sending the message, the client receives the encoded version from the server. This demonstrates the complete cycle of sending, encoding, and receiving.
• Session Termination: Once the encoded message is received, the client session ends. To send another message, the client needs to be restarted.

Overall, this project demonstrates the fundamental principles of network communication using TCP sockets in Java. It showcases how a server can handle multiple client connections, process data (in this case, encoding text), and communicate back to the clients. The client-server architecture employed here is a foundational concept in networked applications, illustrating basic yet crucial aspects of distributed systems and network programming.
