Originally known as just a ‘client’ or ‘thick client’, the name is contrasted to thin client, which describes a computer heavily dependent on a server’s applications.
A fat client still requires at least periodic connection to a network or central server, but is often characterized by the ability to perform many functions without that connection. In contrast, a thin client generally does as little processing as possible and relies on accessing the server each time input data needs to be processed or validated.
