What are the functions of the session layer (Layer 5)?
Give some examples. The session layer is responsible for creating, managing, and ending communication sessions between presentation layer entities. These sessions consist of service requests and responses that develop between applications located on different network devices. Some examples include SQL, RPC, NFS, X Window System, ZIP, NetBIOS names, and AppleTalk ASP. What is the transport layer (Layer 4) responsible for? Give some examples of transport layer implementations. The transport layer segments and reassembles data from upper-layer applications into data streams. It provides reliable data transmission to upper layers. End-to-end communications, flow control, multiplexing, error detection and correction, and virtual circuit management are typical transport layer functions. Some examples include TCP, UDP*, and SPX. Note: watch out for end-to-end on communications on the exam! Transport layer. * Error correction does not apply to UDP – connection-less – unreliable….. What is fl
