Answer:
Wide Area Network (WAN)
A Wide Area Network is a network that extends over a large area.
A WAN is often created by joining several LANs together, such as when a business that has offices in different countries links the office LANs together.
Because WANs are often geographically spread over large areas and links between computers are over long distances, they often use quite exotic connections technologies: optical fibre (glass) cables, satellite radio links, microwave radio links, etc.

The Internet is an example of a global WAN .In fact it is the world’s largest WAN.
Computers on the International Space Station are linked to the Internet, so the you could say the the Internet is now the first off-planet WAN!
Bluetooth (Personal Area Network)
Bluetooth is a wireless networking technology designed for very short-range connections (typically just a few metres).
The idea of Bluetooth is to get rid of the need for all of those cables (e.g. USB cables) that connect our computer to peripheral devices such as printers, mice, keyboards, etc.
Bluetooth devices contain small, low-power radio transmitters and receivers. When devices are in range of other Bluetooth devices, they detect each other and can be 'paired' (connected)
