What is TClientSocket and TServerSocket components

These are components used in the Delphi programming language for creating network applications. These components are part of the VCL (Visual Component Library) framework, which provides a set of pre-built components and controls for developing Windows applications.

TClientSocket: TClientSocket is a client-side socket component that allows Delphi applications to establish connections to remote servers. It uses various network protocols, such as TCP/IP or UDP. It provides methods and properties to connect to a server, send data, and receive data asynchronously. It also supports events to handle different socket events, such as connection established, data received, or errors.

With TClientSocket, you can create applications that communicate with remote servers, such as web servers, email servers, or custom server applications. It simplifies the process of establishing and managing network connections, making it easier to build client applications that interact with remote services.

TServerSocket: TServerSocket is a server-side socket component that allows Delphi applications to create server applications that listen for incoming network connections. It provides methods and properties to bind to a specific network port, listen for incoming connections, and manage multiple client connections simultaneously. Similar to TClientSocket, it supports events to handle various server events, such as a client connection established, data received, or errors.

With TServerSocket, you can create server applications that can accept incoming connections from multiple clients and perform actions based on the received data. It enables the development of various server-based applications, such as chat servers, game servers, or custom server applications.

Both TClientSocket and TServerSocket components are part of the networking capabilities provided by Delphi. These allowing developers to create powerful network applications with ease.
