Bandwidth is generally in bits per second (bps) or Bytes per second (Bps), Kilobytes per second
(Kbps) and Megabytes per second (Mbps). There can be various types of bandwidths, which are
network bandwidth, data bandwidth, or digital bandwidth.
TYPES OF NETWORKS
Networks can be classified based on their size, complexity and the geographical area covered by
them. Let us understand these categories in detail.
PERSONAL AREA NETWORK (PAN)
PAN refers to the privately owned network. Pan is used to
establish communication amongst the computers within the
range of 20 to 30 feet. This type of network can be wired or
wireless.
LOCAL AREA NETWORK (LAN)

number of computers and other peripheral devices within a radius of
less than 1 km. This type of network is useful when you want to connect
two different departments in a building (e.g. an office, a building or
a factory). The hardware, as well as software resources, are shared
through LANs. Your school lab is an example of LAN.
CAMPUS AREA NETWORK (CAN)
CAN connects two or more LANs that are limited to Campus
specific geographical areas. For example, college Network
Area
campus, office building, etc. A campus area network is
larger than LAN since it may span in multiple buildings
within a specified area.
METROPOLITAN AREA NETWORK (MAN)
LAN LAN MAN consists of two or more local area networks or campus
area networks together that usually spans several buildings
in the same city or town. It covers an area ranging from 10
to 100 km. For example, the Internet services provided to
users in a city or the ATM network of any area falls under
LAN
MAN.
