At times, a computer is designed to use multiple protocols. At the receiving end a device called Demultiplexer. Switching could be done without multiplexing, but since the point of switching is to share a network with fewer links than the fully-connected network, it is quite likely these few links will be fat and multiplexing will be used. It sets out to provide students, researchers and nonspecialists alike with a sur. Time Division Multiplexing (TDM) In case of time division multiplexing (TDM), the complete channel bandwidth is allotted to one user for a fixed time slot. There may be several running processes that want to send data and only one transport layer connection available, then transport layer protocols may perform multiplexing.
