What is Rich Client?

A rich client (also known as a fat client or thick client) is a type of client-server architecture where the client-side application performs the majority of data processing operations. It contrasts with a thin client, where the server handles most processing. Rich clients are often characterized by their ability to operate independently of the server, perform complex tasks locally, and provide a rich user experience with advanced graphical interfaces. They are commonly used for applications that require high performance, offline functionality, or sophisticated UI features, such as desktop applications, games, and some business applications.
