A network is basically a set of two or more articles that are linked so the computers can share resources, such as printers, software, and internet connections. Networked computers can also share files without having to transfer data using a disk or data key. And users of networked computers can also communicate electronically without use of the internet. Computers within a network can be linkedseveral ways: though cables, telephone lines, radio waves, satellites, or infrared beams. There are also three basic types of networks: Local Area Networks (LANs), Metropolitan Area Networks (MANs), and Wide Area Networks (WANs).
