Difference in Spatial and Temporal Sharing?

A network is completed when multiple devices connected through a channel or link. Link is basically create a channel between devices in order to communicate or transfer data to each other. Those In  these type of communication channel there could be any device like printer, laptop, thumb device, or any machine which is able to send and receive data. For visualization, suppose a link is a wire or line between two points.

For the purpose of communication two devices must be connected in order to communicate to each other. There are two types of connections which described below.
  1. Point-to-Point Connection
  2. Multipoint Connection

Point To Point Connection/Communication

Point to point connection is simple that two computer/PC are connected via wire. Only these two devices will use this channel-no sharing of channel and no probability to connect more devices with this channel. Simply means Two device and one communication channel. This type of communication is called point to point.

Example of Point-to-Point Line Configuration or communication can be seen below via picture.

Spatial 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.

Temporal sharing

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.
