Question 1 · 1 mark · Difficulty 1/3

A home user wants to connect their laptop to the internet using a wireless connection. The user's internet service provider (ISP) has installed a device that directs data packets between the home network and the wider internet. Which device performs this function?

  1. Switch
  2. Hub
  3. Router
  4. Network interface card
Show answer & explanation
✓ Answer: C — Router
Award 1 mark for Router. A router directs data packets between different networks — in this case, between the home LAN and the internet — using IP addresses to determine the best path. A (Network interface card) is incorrect because a NIC is a component that enables a single device to connect to a network, not a device that routes traffic between networks. B (Hub) is incorrect because a hub simply rebroadcasts data to all connected devices within a single network and cannot route between networks. D (Switch) confuses switching within a LAN with routing between networks; a switch does not direct traffic to external networks.
Question 2 · 1 mark · Difficulty 1/3

Which of the following correctly describes the function of a Network Interface Card (NIC)?

  1. It broadcasts incoming data to all devices connected to the local area network
  2. It allows a device to connect to a network by providing a physical or wireless interface
  3. It routes data packets between different networks using IP addresses
  4. It converts digital signals to analogue signals for transmission over telephone lines
Show answer & explanation
✓ Answer: B — It allows a device to connect to a network by providing a physical or wireless interface
Award 1 mark for B. A NIC is a hardware component installed in or built into a device that provides the interface needed to connect to a network, either via an Ethernet port (wired) or via a wireless antenna (Wi-Fi). A describes the function of a router, not a NIC. C describes the function of a hub, which broadcasts to all connected ports. D describes the function of a modem, which performs signal conversion for transmission over analogue telephone lines.

CIE IGCSE Computer Science: The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections FAQ

How many CIE IGCSE Computer Science questions on The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections for CIE IGCSE Computer Science, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Computer Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections practice with other Computer Science topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections questions aligned to the official CIE IGCSE Computer Science syllabus?
Every question is written against the published CIE IGCSE Computer Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections typically tested on CIE IGCSE Computer Science papers?
The internet and networking: hardware used in networks (router, switch, hub, NIC, WAP) and wired/wireless connections appears across multiple question types on real CIE IGCSE Computer Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
