What is segmentation and what are its two primary benefits?
Segmentation breaks a message into smaller units; this increases speed (no single transfer ties up the link) and efficiency (only lost segments are resent, not the whole stream).
* Breaking a large message into segments, and the two benefits it buys. *
Segmentation is the process of breaking up messages into smaller units.
Two primary benefits:
-
Increases speed - Large amounts of data can be sent over the network without tying up a communications link (allows interleaving of conversations)
-
Increases efficiency - Only segments that fail to reach the destination need to be retransmitted, not the entire data stream
Multiplexing is the process of taking multiple streams of segmented data and interleaving them together for transmission.
Go deeper:
Packet segmentation — why and where data is broken into smaller transmittable units.- Multiplexing — the interleaving of multiple streams that segmentation enables.
