HUBS• It is a hardware device that

is used to connect several computers together.

• It is also known as a central connection for all the computers and Ethernet-based.

• This is beneficial to firms which require lots of data transfer as the information transferred to the hub can be accessed by all connected computers.

BRIDGES• A hardware device which

connects one Local Area Network (LAN) to another LAN, which uses the same protocol.

• Data can be transferred easily to and from the interlinked networks.

• The device is similar to what a router is, but it does not analyze the data, therefore making transitions faster.

SWITCHES• A switch is used to set-up

several computers together, due to their ports.•These ports can be connected to computers, cables, modems etc.•Switches are able to control the amount of data transfer between the ports, enabling each connected device to have a ample amount of bandwidth.

ON-LINE• Online is when a device is

turned on, and able to join other connected devices.

• Devices are also said to be online when they are functioning and connected to a computer system.

OFF-LINE• Offline is a complete

contrast to the definition of online.

• When a device is not connected to any computer system, so there cannot be any data transferred between the devices.
