Switches
Switch is a networking device that groups all the devices over the
network to transfer the data to another device. A switch is better than
Hub as it does not broadcast the message over the network, i.e., it
sends the message to the device for which it belongs to. Therefore, we
can say that switch sends the message directly from source to the
destination.
Cables and connectors
Cable is a transmission media that transmits the communication signals.
There are three types of cables:
- Twisted pair cable: It is a high-speed cable that transmits the data over 1Gbps or more.
- Coaxial cable: Coaxial cable resembles like a TV
installation cable. Coaxial cable is more expensive than twisted pair
cable, but it provides the high data transmission speed.
- Fibre optic cable: Fibre optic cable is a
high-speed cable that transmits the data using light beams. It provides
high data transmission speed as compared to other cables. It is more
expensive as compared to other cables, so it is installed at the
government level.
