Segmentation and Multiplexing


Let's say, a computer is sending a huge size of data across the network and will takes 1 hour to finish sending (see the green compuer above). If its message is not segmented, there is no way for other devices to share the link. Other devices will need to wait for the green computer to finish up send its data before they can use the link.


Network is normally shared by many end devices. The reason why we have to do segmentation is to be fair to all end devices in the network. During the segmentation process, data from each end devices are sent in small part called "chunks".

Multiplexing is the process whereby all different "chunks" of data from different end devices are combined together and transmitted in a link.
