A fat client (sometimes called a thick client) is a networked computer with most resources installed locally, rather than distributed over a network as is the case with a thin client. Most PCs, are fat clients because they have their own hard drive, DVD drives, software applications, etc.
A thin client is a computing device that’s connected to a network. Unlike a typical PC or “fat client,” that has the memory, storage and computing power to run applications and perform computing tasks on its own, a thin client functions as a virtual desktop, using the computing power residing on networked servers.
