A student investigates the differences between wired and wireless network connections. She notes that one type of connection transmits data using radio waves and does not require a physical cable between the device and the network. Which of the following is a disadvantage of this type of connection compared to a wired connection?

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 investigates the differences between wired and wireless network connections. She notes that one type of connection transmits data using radio waves and does not require a physical cable between the device and the network. Which of the following is a disadvantage of this type of connection compared to a wired connection?

Accepted Answer

It is more susceptible to interference from other devices — Award 1 mark for B. Wireless connections transmit data using radio waves, which can be disrupted by other devices operating on the same or nearby frequencies, physical barriers such as walls, and other sources of electromagnetic interference, reducing reliability compared to wired connections. A is incorrect because wireless network cards (Wi-Fi NICs) are required for wireless connections, but NICs are also required for wired connections, so this is not a disadvantage unique to wireless. C is incorrect because wireless access points can support multiple devices simultaneously. D is incorrect because wired connections — not wireless — typically use a switch for LAN connectivity.
