signals reducing the noise component of the signals. It is used at places where
amplification of input signal is necessary.
ROUTER

using the same IP. It works on the network layer. In other words, it is
used to connect and facilitate the transfer of information between two
networks.
NETWORKING CABLE

allows to transport information from one place to another place. There are
various types of networking cables such as coaxial cable, twisted-pair cable,

MODEM
A modem is a device that is used to transmit data over a network. It is
attached to computers that can convert digital signals (to be transmitted over
telephone lines) to analog (continuous electrical waves) and convert analog
signals to digital signals at the receiving end.
Modem is the short form of Modulator-Demodulator where the modulator can convert digital
signals to analog and the demodulator does the opposite.
GATEWAY
A gateway is a network device that allows 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.
