Hub
A device that transmits data packets from one computer to all connected computers.
1 of 12
Switch
A device that intelligently routes data packets to their destination, rather than broadcasting to every device.
2 of 12
Explain the difference between a network hub and a switch.
A hub transmits data packets to all connected devices. A switch transmits only to the destination.
3 of 12
Router
A device that intelligently determines the most efficient path for a data packet to travel.
4 of 12
What information is used by the router to determine the path taken by a data packet?
The list of all networks the router is connected to (routing table). The destination address of the data packet. The congestion of each of the paths.

Wireless Acess Point (WAP)
A device that converts wireless data packets to be wired, and back again.
6 of 12
How can data be transferred between a wireless device and a wired network?
Packets to a nearby WAP. They are converted into wired data packets and transmitted to the hub/switch, which passes them to the destination. The process is also carried out in reverse.

Network Interface Card (NIC)
A chip or card that converts data from a device into a format compatible, and vice versa.

MAC address
Media Access Control. A unique identifier for a device connecting to a network.

Data Packet
A chunk of data with a destination address.
