POE can be used for a quantity of applications, like digital cameras, safety systems, and intelligent sensors.

Inspection of internal or restricted information, or the monitoring of messages (like electronic mail), when there is reasonable lead to to suspect improper use of the computer or network sources can be authorized by the College’s Chief Details Officer or other senior staff. If the file server breaks down the files on the file server grow to be inaccessible. E mail might nevertheless perform if it is on a separate server. The computers can still be utilised but are isolated.Uses Of Computer Networks

These are applications that run on stand alone computers (computer systems not connected to any other). In order to extend their activity, they are rebuild to run on network environments e.g. word processors, spreadsheets, database management systems, presentations graphics, project management and so on. They function even when the laptop is offline.
