Types of networks

Personal Area Network (PAN)
A personal area network (PAN) is a computer network used for communication among computer devices close to one person. Some examples of devices that are used in a PAN are printers, fax machines, telephones, PDAs or scanners.

The reach of a PAN is typically within about 20-30 feet (approximately 6-9 metres).
Personal area networks may be wired with computer buses such as USB and FireWire.

A wireless personal area network (WPAN) can also be made possible with network technologies such as IrDA and Bluetooth..
