Difference in Spatial and Temporal Sharing?

Difference between spatial and temporal sharing with figure and solid examples

A communication channel (link) can be used in two ways between devices

Two device-one communication channel –only these two devices will use this channel-no sharing of channel capacity other than these 2 devices. This type of communication is called point to point.

Spatial sharing

Temporal sharing

In spatial sharing many devices -one communication channel - several devices want to communicate at one time

In this situation channel capacity is distributed (shared) between devices. There are many ways of sharing channel capacity like Frequency division (details will come in upcoming lectures).

Example: internet communication, Telephony communication.

In temporal sharing many devices-one communications channel-several devices want to communicate

In this situation all devices are given a time spam in which they can utilize that single link. At that time other device will not send their data on link.it mean at a time only one device will send data on link.

Example: Mainframe computer working environment-workstations send data to this mainframe computer.
