TCP Client: Definition, Applications, and Programming

A TCP client is a program or application that establishes a connection with a TCP server. The client initiates the connection by sending a request to the server, and then waits for a response. Once the connection is established, the client and server can exchange data in a reliable, ordered, and error-checked manner. TCP clients are used in a wide variety of applications, including web browsing, email, file transfer, and online gaming. They are typically built using programming languages such as Java, C++, Python, or Ruby.
