B The device can sit anywhere in the school

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1Ethernet cable		ANetwork cables have length limits, so a cable that is far too long will not carry data well. The computer must be closer to the router or switch.
2Ethernet port		BThe socket on a computer, switch or router where a network cable plugs in
3A cable connects a computer to a switch so the computer can send data to the network		Ccable length: 100 m max
4A cable can only be so long, so a wired device must sit within cable reach of the switch or router		DA network cable only fits a network port, such as an Ethernet port. It does not go in a headphone socket, so no data would travel.
5Plug the network cable into the headphone socket		EA network cable that plugs into an Ethernet port to carry data between a device and the network
6A 500 m cable runs from the classroom computer to the router		Fcomputer --cable--> switch

Answer Key

Network cable

Section A: Quick Questions

A — It carries data between a device and the network

A — An Ethernet port

B — Plug one end into the computer and the other into a switch or router

B — Data

A — The device has to sit fairly close to the switch or router

Section B: Match the Pairs

Ethernet cable → A network cable that plugs into an Ethernet port to carry data between a device and the network

Ethernet port → The socket on a computer, switch or router where a network cable plugs in

A cable connects a computer to a switch so the computer can send data to the network → computer --cable--> switch

A cable can only be so long, so a wired device must sit within cable reach of the switch or router → cable length: 100 m max

Plug the network cable into the headphone socket → A network cable only fits a network port, such as an Ethernet port. It does not go in a headphone socket, so no data would travel.

A 500 m cable runs from the classroom computer to the router → Network cables have length limits, so a cable that is far too long will not carry data well. The computer must be closer to the router or switch.

Section C: Definitions

network cable — A wire that carries data between a device and the network. It plugs into a network port, like an Ethernet port, on a computer, switch or router.

Section D: Fill in the Blanks

A network cable carries data to the network.

A cable plugs into an Ethernet port.

computer -> cable -> switch

A short cable limits where a device can sit.

connect(computer, cable, router)

Section E: Spot the Error

C — A network cable carries data between a device and the network, not just power. Line 1 should say: A cable carries data.

C — With a network cable, data travels along the wire. Travelling through the air is wireless. It should be: data travels along the cable.

A — A power cord brings electricity. A network cable that carries data is an Ethernet cable. Line 1 should be: cable = Ethernet.

C — The desk is only 20 m from the switch and the limit is 100 m, so the cable is long enough. It should be: cable is long enough.

D — The cable carries data from the device to the network, so the data does not stay inside it. It should be: data reaches the network.
