A network is a group of 2 or more computer systems linked together to exchange data and share resources, including expensive peripherals such as high-performance laser-printers.
Network types are local area networks, home networks, wireless LAN, personal area networks, metropolitan area networks, and wide area networks.
Computer networks fall into 2 categories: local area network (LAN) and wide area network (WAN).
LAN uses cables, radio waves, or infrared signals to link computers or peripherals e.g. printers, within a small geographic area, e.g. building or group of buildings.
WAN uses long-distance transmission media to link computers separated by few miles or even thousands of miles. The Internet is the largest WAN as it connects millions of LANs all over the globe.

Advantages of Networking
- Reduced hardware costs.
- Application sharing.
- Sharing information resources.
- Centralised data management.
- Connecting people.
- Loss of autonomy.
- Lack of privacy.
- Security threats.
- Loss of productivity.
That's all for networks!
