A gateway is a network device that allows the data to flow between two
different networks which may use different protocols. It collects data
that is to be sent from one computer, converts it into small packets
and then sends them to another computer.

TYPES OF NETWORKS
Different types of networks can be classified on the basis of geographical area they cover. There are
five types of networks as follows:
LAN (Local Area Network)
LAN stands for Local Area Network. It is a digital communication system that interconnects a large
number of computers and other peripheral devices within a radius of less than 1 km. This type of
network is usually preferred for a smaller area such as a residence, school, laboratory, university
campus or office building. By using the LAN network, users can exchange data and messages in the
easy and fast way. Cables and communication devices are used to connect computers to the LAN.

Local Area Network
Imagine, computer networks as highways in the sky. What vehicles would travel on
these highways and what destinations would they reach?
MAN (Metropolitan Area Network)
This network consists of two or more local area networks or campus area networks together and
usually spans several buildings in the same city or town.
