Thin client uses stateless connections. For each request connection will be opened and after the response it will be closed	Thick client uses dedicated connections
Thin clients are slower in response • Connection needs to be opened explicitly for each request • Pages needs to be downloaded from presentation layer • Data needs to be retrieved from the DB • Business logic related processing will be happening in the middle wares or application servers	Thick clients are faster in response • most of the processing happens locally • Connections will be closed only explicit logouts
