A computer network refers to the hardware (computers, cables etc)
and software (operating systems etc) which are inter-connected (handshaking)
to communicate and share data. At the most basic level, a computer
network can be comprised of just a single device to send data and
a single remote device to receive the data. Because of the geographical
difference in the scope of computer networks, there has been a process
to classify these differences. Provided below is a list of the most
common types of geographical computer network.
BAN - Body Area Network - Comprises communication between
sensors placed on the human body.
CAN - Campus Area Network - Refers to a number of LAN's
connected together at governmental and educational buildings such
as college's and universities.
HAN - Home Area Network - As the name would suggest, a HAN
is the connection of network enabled devices in a domestic home.
LAN - Local Area Network - The scope of a LAN is larger
than that of a HAN and smaller than that of a CAN. A LAN is typically
the network of computers placed in a school or a small office.
MAN - Metropolitan Area Network - Larger than a CAN, a MAN
covers a wide metropolitan area - such as city centre - and incorporates
high capacity (backbone) networking hardware.
PAN - Personal Area Network - Refers to communication from
and between small handheld devices - such as mobile phones, smartphones,
WAN - Wide Area Network - The largest of the geographical
computer networks listed on this page. WAN's connect regional and
national computer networks together.
