Cables and Connectors: JAMB Computer Studies Questions, Answers & Notes

What Cables and Connectors covers in the JAMB Computer Studies syllabus

Cables are used to connect computer devices together and carry signals or power; a connector is the plug (end piece) of a cable that fits into a matching port (a socket on the computer). Common cables include the USB (Universal Serial Bus) cable for peripherals like flash drives, printers, keyboards and mice; the HDMI cable, which carries high-quality video and audio to a monitor or TV; the Ethernet (network) cable, used to connect computers in a wired network (with an RJ45 connector); the older VGA cable, which carries only video; and the fibre optic cable, made of glass, which carries data as pulses of light faster and over longer distances than ordinary copper cables. Cables and connectors must match the ports they plug into. The main point: cables (USB, HDMI, Ethernet, fibre optic) and their connectors join devices by plugging into matching ports.

For Cables and Connectors, JAMB expects you to be able to:

• Define cables/connectors/ports and their role (connect devices, carry signals/power)
• Identify common cables (USB, HDMI, Ethernet/network, VGA, fibre optic) and their uses
• Recall connectors (RJ45), that cables must match ports, and fibre optic's speed advantage

Worked examples

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

How Cables and Connectors is tested in JAMB Computer Studies

Our Cables and Connectors bank holds 20 questions (2 easy, 12 medium, 6 hard). JAMB Computer Studies typically returns to Cables and Connectors 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 Cables and Connectors 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 Cables and Connectors. 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 Cables and Connectors is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Cables and Connectors

The errors that cost marks on Cables and Connectors 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 Cables and Connectors actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
