A network technician notices that when one computer in the network sends a large file to another computer on the same LAN, all other computers experience a significant slowdown in their network performance. Which network device is most likely responsible for this behaviour?

Q: How do I try a free CIE Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A network technician notices that when one computer in the network sends a large file to another computer on the same LAN, all other computers experience a significant slowdown in their network performance. Which network device is most likely responsible for this behaviour?

Accepted Answer

Hub — Award 1 mark for Hub. A hub broadcasts all incoming data to every connected device, regardless of the intended recipient. When a large file is transmitted, the entire bandwidth of the hub is consumed and all devices receive the data simultaneously, causing a collision-prone environment and significant performance degradation for all users. A (Switch) is incorrect because a switch forwards data only to the intended recipient's port, meaning other devices are unaffected during large file transfers. B (Router) is incorrect because a router operates between networks and would not cause this behaviour within a single LAN. D (Wireless access point) is incorrect as it provides wireless access rather than this type of broadcast behaviour on a wired LAN.
