Computer Maintenance: JAMB Computer Studies Questions, Answers & Notes

What Computer Maintenance covers in the JAMB Computer Studies syllabus

Computer maintenance means keeping a computer in good working condition. It can be preventive (cleaning, dusting and checking parts to stop faults before they happen) or corrective (repairing a fault after it has occurred), and it covers both hardware (the physical parts) and software (updating and cleaning programs). Good practices include removing dust to prevent overheating, installing and updating anti-virus software, doing disk clean-up to free space, running defragmentation to make a hard disk faster, and using a voltage stabiliser or UPS to protect against power surges and outages. Keeping the computer in a cool, dust-free place also helps. Regular maintenance prolongs (extends) the life of a computer. The main point: computer maintenance (preventive and corrective, hardware and software) keeps a computer working and prolongs its life.

For Computer Maintenance, JAMB expects you to be able to:

• Define computer maintenance and distinguish preventive vs corrective, hardware vs software
• Recall practices (dusting/cleaning, anti-virus, disk clean-up, defragmentation, stabiliser/UPS)
• Explain that good maintenance and environment prolong a computer's life

Key facts & revision notes: Computer Maintenance

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

• Computer maintenance means keeping a computer in good working condition.
• Preventive maintenance (cleaning, dusting, checking) is done to stop faults before they happen.
• Corrective maintenance is repairing a fault after it has happened.
• Hardware maintenance deals with the physical parts of the computer.
• Software maintenance deals with updating and cleaning programs.
• Removing dust prevents overheating and keeps parts working well.
• Installing and updating anti-virus software is part of software maintenance.
• Disk clean-up deletes unwanted files to free storage space.
• Defragmentation rearranges fragmented files so a hard disk works faster.
• A voltage stabiliser or UPS protects a computer from sudden power surges and outages.
• Keeping the computer in a cool, dust-free place helps it last longer.
• Regular maintenance prolongs (extends) the life of a computer.
• Computer maintenance is keeping it in good working condition.
• Cleaning to prevent faults is preventive maintenance.
• Repairing after a fault is corrective maintenance.
• Removing dust prevents overheating.
• Anti-virus is part of software maintenance.
• Protecting against power surges uses a stabiliser/UPS.

• The main point is that computer maintenance (preventive and corrective, hardware and software) keeps a computer working and prolongs its life.

Worked examples

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

How Computer Maintenance is tested in JAMB Computer Studies

Our Computer Maintenance bank holds 20 questions (3 easy, 12 medium, 5 hard). JAMB Computer Studies typically returns to Computer Maintenance 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 Computer Maintenance 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 Computer Maintenance. 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 Computer Maintenance is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Computer Maintenance

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