LANs & WANs
The main reason organisations connect their devices into a network is so that shared resources can be used by everyone, instead of buying and storing a copy for every machine. A device that joins the network can use resources held elsewhere on it, such as a printer in another room.
A small recording studio with three edit rooms shows the saving: one printer, one copy of the editing software on the server and one broadband connection are shared by all three rooms, which costs far less than three printers, three software licences and three broadband lines.
Communication covers email, messages and video calls between users. Collaboration goes further: several people edit the same shared document at once, or book a slot on a shared calendar, without swapping copies. Work carries on even when people are in different rooms or different buildings.
Because files and accounts sit on central machines, one technician can look after the whole network:
Central storage also means files can be opened from any connected device, so you can log on at a different workstation and carry on where you left off.
