REPEATER
The Repeater regenerates the input signals and amplifies only the desired
signals reducing the noise component of the signals. It is used at places where
the amplification of the input signal is necessary.
ROUTER
A router is used when multiple devices need to connect to the Internet
using the same IP. It works on the network layer. In other words, it
is used to connect and facilitate transfer of information between two
networks.
NETWORKING CABLE
Networking cable also known as Ethernet cable is a transmission medium
that allows transporting of information from one place to another. There are
various types of networking cables such as coaxial cable, twisted pair cable,
and optical fibre cable.
MODEM
Modem is a device which 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 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.
