Networking: JAMB Computer Studies Questions, Answers & Notes

What Networking covers in the JAMB Computer Studies syllabus

A computer network is two or more computers connected together to share data and resources such as printers, files and internet access. By size, a LAN (local area network) covers a small area like one building, while a WAN (wide area network) covers a large area like a country — the internet is the biggest WAN. The way computers are arranged is the network topology (star, bus, ring), and a wireless local network is commonly called Wi-Fi. Network devices include the router (connects networks and directs data between them), the switch or hub (connects computers within a LAN), the server (a powerful computer that provides services) and the client (a computer that requests services). Networking's advantages include resource sharing, while its disadvantages include the risk of viruses spreading and security threats. The main point: networking connects computers to share resources; types include LAN and WAN, using devices like routers, switches and servers.

For Networking, JAMB expects you to be able to:

• Define a computer network and its purpose (sharing data and resources)
• Distinguish LAN (small area) from WAN (large area/internet); recall topology and Wi-Fi
• Recall network devices (router, switch/hub, server, client) and advantages/disadvantages

Key facts & revision notes: Networking

These are the recurring points our Networking questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• A computer network is two or more computers connected together to share data and resources.
• A LAN (local area network) covers a small area like one building or office.
• A WAN (wide area network) covers a large geographical area, like a country; the internet is the biggest WAN.
• A network lets computers share resources like printers, files and internet access.
• A router connects networks and directs data between them.
• A switch (or hub) is a central device that connects computers in a LAN.
• A server is a powerful computer that provides services and resources to other computers (clients) on a network.
• A client is a computer that requests services from a server.
• Network topology is the way computers are arranged and connected in a network (star, bus, ring, etc.).
• A wireless local network is commonly known as Wi-Fi.
• An advantage of networking is the sharing of resources (files, printers, internet).
• A disadvantage of networking is the risk of viruses spreading and security threats.
• A computer network is computers connected together.
• A network in one building is a LAN.
• A network covering a country is a WAN.
• A computer that provides services on a network is a server.
• A device that directs data between networks is a router.
• A wireless local network is Wi-Fi.
• An advantage of networking is resource sharing.
• The main point is that networking connects computers to share resources; types include LAN (small area) and WAN (large area), using devices like routers, switches and servers.

Worked examples

Three Networking questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Networking is tested in JAMB Computer Studies

Our Networking bank holds 20 questions (3 easy, 10 medium, 7 hard). JAMB Computer Studies typically returns to Networking year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer Networking questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on Networking. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Computer Studies item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at Networking is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Networking

The errors that cost marks on Networking are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise Networking actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.

Frequently asked questions

Is Networking part of the JAMB Computer Studies syllabus?

Yes. Networking is a recognised topic in the JAMB Computer Studies syllabus, covering define a computer network and its purpose (sharing data and resources). You should be able to recall its key facts and apply them to multiple-choice questions.

How many Networking questions can I practise on Belmadeng?
