1CP2-P-6.8 Networks checkpoint

Part 8 of 8 · 1CP2-P-6 · Networks

The checkpoint for the whole networks series, sampling LAN and WAN, the internet, performance, media and topologies.

Students will:

  • explain two differences between a LAN and a WAN
  • describe how DNS, IP addresses and routers deliver a request
  • construct a transmission-time expression with correct conversions
  • explain fibre transmission and one advantage over copper
  • give one advantage and one disadvantage of replacing wired with wireless

Inside: 2 explanation cells, 1 multiple-choice question and 9 written answers. 20 marks, about 45 minutes.

Series: 1CP2-P-6 · Networks, part 8 of 8.

1CP2-P-6 networks checkpoint

This checkpoint assesses the Y10-6 principles series. It introduces no new content. Read units and scenarios carefully, and develop explanations through a mechanism and consequence.

Written answer1 mark

State one reason why an organisation connects devices in a network.

Give one specific purpose.

Students type their answer here.

Written answer2 marks

Explain two differences between a LAN and a WAN.

Use geographical coverage and infrastructure or what is connected.

Students type their answer here.

Multiple choice1 mark

Which unit is appropriate for wireless range?

  • AMbit/s
  • Bbytes
  • Cmilliseconds
  • Dmetres
Written answer2 marks

Describe how DNS, IP addresses and routers help a browser request reach a web server on another network.

Give the stages in order.

Students type their answer here.

Written answer2 marks

A file must be downloaded from a server. Name a suitable protocol and explain why protocols are needed for network communication.

Give the file-transfer protocol and the purpose of agreed rules.

Students type their answer here.

Written answer4 marks

Construct an expression for the time needed to transmit a 1.4 GiB file at 25 Mbit/s. Use 1 GiB = 1024³ bytes. You do not need to evaluate it.

Show file-unit, byte-to-bit and rate conversions.

Students type their answer here.

Written answer2 marks

Explain how data is transmitted through fibre-optic cable and give one performance advantage over copper.

Name the signal and link the advantage to a use.

Students type their answer here.

Written answer2 marks

A school replaces wired connections to classroom laptops with Wi-Fi. Explain one advantage and one disadvantage.

Link each point to mobile classroom use or network performance.

Students type their answer here.

Written answer2 marks

Explain one disadvantage of a bus topology.

Name the shared backbone and give a linked consequence.

Students type their answer here.

Written answer2 marks

A medical centre needs alternative communication routes if one link fails, but cannot afford a direct link between every pair of devices. Recommend a topology and justify it.

Balance reliability and cost.

Check before submitting

Make sure comparisons describe both sides, calculations show compatible units, and explanations identify a mechanism and its consequence. Your teacher will review the checkpoint responses.
