A student is asked to explain why a wireless network connection may be less secure than a wired connection. Which of the following is the most appropriate reason?

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 student is asked to explain why a wireless network connection may be less secure than a wired connection. Which of the following is the most appropriate reason?

Accepted Answer

Wireless signals can be intercepted by any device within range without needing physical access to the network — Award 1 mark for B. Because wireless networks transmit data as radio waves through open air, any device equipped with a wireless NIC and within range can potentially detect and capture the transmitted signals. This makes wireless networks inherently more vulnerable to eavesdropping than wired networks, where an attacker would require physical access to the cable to intercept data. A is incorrect because the relative ease of forging MAC vs IP addresses is not the primary security concern distinguishing wireless from wired connections. C is incorrect because wireless networks can and do use encryption (e.g. WPA2), and wired networks do not always encrypt data automatically. D is incorrect because WAPs can support many more than ten devices simultaneously.

Answer

Wireless access points cannot support more than ten devices at the same time

Answer

Wireless networks do not use encryption, whereas wired networks always encrypt data

Answer

Wireless signals can be intercepted by any device within range without needing physical access to the network

Answer

Wireless connections use MAC addresses which are easier to forge than IP addresses
