- 3SwitchesA switch is a device in a computer network that electrically and logically connects together other devices. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received message only to the one or more devices for which the message was intended. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. This maximizes the security and efficiency of the network.
- 4CoaxialAdvantages:
Easy installation
Lowest cost of the three communication media.
Disadvantages:
Electrical signal communication through wires. This is not energy efficient.
High noise contamination.
Can be affected by external magnetic interference.
Low bandwidth meaning less data can be transferred during download and upload. - 5Twisted coaxialAdvantages
