🔘Wide Area Network
🔘A wide area network is formed by connecting a number of LANs through a router or a modem.
🔘It covers a much larger geographical area than a LAN.
🔘Private WANs can be set up by organisations to connect their LANs by the means of leasing telephone lines...
...or private fibre optic cable purely for their own use...
...these can be Virtual Private Networks (VPNs).
🔘The use of an existing telecommunications network causes data transmission rates to be slower in a WAN than a LAN.
