The session layer allows for communication between two applications. It is responsible for establishing a connection between the two applications, maintaining it during the transfer of data, and controlling the release of these connections. The session layer protocol can enable communication between the two applications by three different modes 1) Simple is communication that takes place in one direction. 2) Half-duplex allows communication to take place in both directions, but only one application can send information at one time. 3) Full-duplex allows communication to take place in both directions and both applications can send information at the same time.
