REPEATER
A repeater regenerates and retransmits signals in a communication network.
It takes a weakened or corrupted signal and restores it to its original strength
or quality before sending it onward. Repeaters are used to extend the distance
over which data can be transmitted by eliminating signal degradation caused
by distance, noise, or interference.
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 or
more networks.
NETWORKING CABLE
Networking cable, also known as Ethernet cable, is a transmission medium
that allows the transfer of data between devices. 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 converts digital signals
to analog and the demodulator converts analog signals back into digital.
GATEWAY
A gateway is a network device that allows the data to flow between two different
networks that may use different protocols. It collects data that is to be sent from
one device, converts it into small packets and then sends them to another device.
