Types of Clients

There are primarily two types of clients:

• Thin client
• Thick client (sometimes also called the Fat client)

Thin client#

A thin client is a client that holds just the user interface of the application. It contains no business logic of any sort. For every action, the client sends a request to the backend server, just like in a three-tier application.

Thick client#

On the contrary, the thick client holds all or some part of the business logic. These are the two-tier applications. We’ve already been through them.

The typical examples of fat clients are utility apps, online games, and so on.
