Stateless systems or protocols do NOT maintain state and prior knowledge (data) does NOT affect the processing of the current data.

Stateless protocol does not require the server to retain sessionData or status about each communications partner for the duration of multiple requests.

In contrast, to a stateful protocol or system.

Stateless systems are not dependent on any single instance of the server. This implies a loss of a server has no effect as long as there are more than one instances available.

Stateless systems may not have any Cache or data Store
