REST stands for Representational State Transfer.
REST is an architectural style for designing interfaces for web based services.
A web client manipulates a resource’s state by sending a representation as part of an HTTP PUT or POST request, (DELETE operations don’t have a representation). In turn, the server manipulates client state by sending representations in response to client’s requests. This is where the term “Representational State Transfer” comes from.
