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.

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.
State one reason why an organisation connects devices in a network.
Give one specific purpose.
Students type their answer here.
Explain two differences between a LAN and a WAN.
Use geographical coverage and infrastructure or what is connected.
Students type their answer here.
Which unit is appropriate for wireless range?
- AMbit/s
- Bbytes
- Cmilliseconds
- Dmetres
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.
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.
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.
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.
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.
Explain one disadvantage of a bus topology.
Name the shared backbone and give a linked consequence.
Students type their answer here.
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.
Students type their answer here.
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.
