There are many connecting devices used in local area networks:
• Repeater
• Hub
• Switch
• Router
• Access point
8.4.1 Repeater
The signal is susceptible to interference and distortion during the transmission
process, so a Repeater device is used to regenerate the transmitted signal across the
network, making it strong upon reception.
8.4.2 Hub
It serves as a central connecting point between
network devices by linking them together. However,
its drawback is that it rebroadcasts signals on all of
its ports, making it susceptible to collisions between
them .
8.4.3 Switch
It is the most commonly used to connect network
devices because it directs the message to the port
where the destination device is located, whereas a
hub broadcasts the message to all ports. Therefore,
the switch is faster in data transfer, reduces
collisions, and also has the capability to send and receive simultaneously.
