Understanding and Coding a TCP Client

Coding a TCP Client

Creating a TCP (Transmission Control Protocol) Client is often the first step for many developers who are looking to build networking applications. Creating a client involves two parts: creating a socket and then sending requests through the socket.

Creating a Socket

The first step in coding a TCP Client is creating a socket. A socket is an endpoint for communication between two machines. To create a socket, the server side binds to a specific port number that both sides of the connection can agree upon. The client must then connect to the server using the same port number.

Sending Requests

Once the socket is created, the client application can send requests to the server. These requests can be anything from a simple ping request to complex requests such as downloading a file or streaming media. The client application will receive a response from the server based on the request sent. The client application can then interpret the response and act accordingly.

Conclusion

Writing code for a TCP Client involves two parts: creating a socket that connects to the server, and then sending requests through the socket. The response from the server can then be interpreted by the client application and the appropriate action can be taken accordingly.
