9. Network range and speed: Talking about network capabilities. Network terminology. Business matters Depending on the network type, devices can be as simple as computers or smartphones that connect into a network. Larger networks use devices like routers and switches to create the underlying network infrastructure.
Not all networks are the same. There are several types of networks, each existing to support the devices, size and location of the system. Networks also have differing levels of access and forms of connectivity.
Below are seven common types of networks, along with their benefits and use cases.
1. Personal area network
A personal area network (PAN) is the smallest and simplest type of network. PANs connect devices within the range of an individual and are no larger than about 10 meters (m). Because PANs operate in such limited areas of space, most are wireless and provide short-range connectivity with infrared technology.
An example of a wireless PAN is when users connect Bluetooth devices, like wireless headsets, to a smartphone or laptop. Although most PANs are wireless, wired PAN options exist, including USB.
PAN benefits
Portability. Most devices that connect in a PAN are small and can be easily transported.
Affordability. The ability to form a connection between two devices in a PAN without additional wiring is generally less expensive compared to a wired network.
Reliability. PANs guarantee stable connectivity between devices, provided that the devices remain within the 10 m range.
Security. PANs don't directly connect to larger networks, but rather to other devices connected to larger networks. The security of a device in a PAN is contingent upon how secure the intermediary device is within the larger overall network.
PAN use cases
PANs are configured so individual users can connect their devices within their personal vicinity. A literal example of this is a body area network, in which a user physically wears connected devices.
