Personal Area Network (PAN)
A PAN is the simplest and most basic sort of network, consisting of a
wireless modem, one or more computers, phones, printers, tablets, and
other devices that revolve around one person in one building. These
networks are commonly found in small offices or homes, and they are
controlled by a single person or organisation using a single device. The
range of PAN is 10 meters.
Local Area Network (LAN)
LANs are one of the most commonly used networks, as well as one of the
most prevalent, unique, and basic forms of networks. These networks allow
groups of computers and low-voltage devices to share information and
resources over a radius of up to 1 KM (inside a building or between two or
three buildings near each other). This type of network is generally maintained
by an organisation. Its speed ranges from 10 Mbps to 1 Gbps.
Metropolitan Area Network (MAN)
A MAN is larger than a LAN or we can say that it is a combination of multiple LANs. A single entity or a group of persons
or organisations may own a MAN. It is used to create connections within a city and can cover a radius of up to 50 KM.
By connecting several local area networks, a MAN makes resource sharing easier. One of the best examples of MAN is
a cable television network within a city.

Wide Area Network (WAN)
A WAN, which is slightly more complicated than a LAN, connects computers over longer physical distances. It enables
computers and low-voltage devices to communicate over a single huge network even when they are thousands of
kilometres distant. It establishes links within a country or continent by connecting several local and metropolitan area
networks. The Internet is the most fundamental type of WAN, as it connects millions of computers worldwide. A WAN
is often owned and maintained by many administrators or the general public because of its extensive reach.
