Your computer had a problem. You restarted it, checked the cables, and fixed a small software or hardware issue. Now it works again. Is the job done? Not yet. This topic is about what comes after the fix.
The steps you take after a problem is solved have a name.
These extra steps help the computer keep working well. They also stop the same problem from coming back. The goal of this whole chapter is a computer that is stable, secure, efficient and reliable.
Importance of Continuous Maintenance
Fixing a problem once is not enough. A computer needs care again and again. If nobody looks after it, the old problem can return, or a new one can start.
When you look after the computer regularly, three good things happen:
- it performs better,
- it lasts longer,
- it gets interrupted less while you use it.
Impact of Poor Maintenance
What happens when a computer is not looked after? The book lists five common problems. Each one has a clear cause.
| Problem | What causes it |
|---|---|
| Slow Performance | Temporary files, unused programs and background processes pile up and are not managed. |
| System Failures | Important system updates are not installed, so the computer may freeze, crash or not start. |
| Security Risks | The system or apps are not updated, so viruses and other harmful software get in more easily. |
| Data Loss | There are no backups, so important files can disappear in a crash or a hardware failure. |
| Hardware Damage | Dust and too much heat harm the parts when the computer is not cleaned or does not get enough air. |
Notice a pattern: two of the five problems come from skipping updates. That is why updates matter so much.
Introduction to System Health Monitoring
A doctor checks your heartbeat to catch problems early. A computer can be checked in a similar way.
Modern operating systems, such as Microsoft Windows, come with their own tools for this. The book says these tools let you:
- Check how much memory and processing power are being used
- Monitor background applications and services
- View system warnings and error messages
- Identify programs that may slow down the computer
Why bother? When you check often, you catch small problems while they are still small. Then you can act in time, keep the computer fast, and avoid bigger trouble later.

Short questions
1.What is post-troubleshooting maintenance?2 marks
Answer
After troubleshooting fixes a common computer problem, the next step is to learn what actions to take once the issue is resolved. This process is called post-troubleshooting maintenance. It includes additional steps that help the computer continue to work properly and avoid the same problems in the future.
2.Why is continuous maintenance important even after a problem is solved?3 marks
Answer
Solving a computer problem is only the first step. The system still needs regular care to continue working properly. Without maintenance, the same issue can happen again, or new problems may appear. Regular maintenance keeps the system stable and prevents future problems. It ensures better performance, longer life, and fewer disruptions in computer usage.
3.Give the book's example that shows why a one-time fix is not enough.2 marks
Answer
If the computer becomes slow due to full storage, deleting a few files may improve its speed for a short time. However, if unnecessary files are not removed regularly or the system is not updated, the same issue may occur again.
4.List five common problems that result from a lack of regular maintenance.3 marks
Answer
- Slow Performance
- System Failures
- Security Risks
- Data Loss
- Hardware Damage
5.How can poor maintenance cause slow performance and system failures?4 marks
Answer
Slow Performance: Temporary files, unused programs, and background processes can build up over time. If these are not managed, the computer may become slow and unresponsive. System Failures: If important system updates are not installed, the computer may stop working properly. It can freeze, crash, or fail to start.
6.Explain security risks, data loss and hardware damage as results of poor maintenance.4 marks
Answer
Security Risks: When the system or apps are not updated, harmful software like viruses can enter the computer more easily. Data Loss: Without backups, important files can be lost during crashes or hardware failure. Hardware Damage: Dust and overheating can damage the hardware components if the system is not cleaned or properly ventilated.
7.Define system health monitoring.2 marks
Answer
For the smooth running of a system, it is important to check its performance regularly. This process is known as system health monitoring. Modern operating systems, such as Microsoft Windows, include built-in tools that help monitor system activity.
8.What do built-in system monitoring tools allow you to do, and how does regular monitoring help?4 marks
Answer
These tools allow you to check how much memory and processing power are being used, monitor background applications and services, view system warnings and error messages, and identify programs that may slow down the computer. Regular monitoring helps detect small issues before they become serious.
Long questions
1.Explain the impact of poor maintenance on a computer system. Describe the five common problems that result from a lack of regular maintenance.8 marks
Answer
Start with the book's lead-in, then cover all five problems in the book's words:
- Lead-in (verbatim): "If a computer is not maintained regularly, it may face several problems that affect its performance and reliability."
- Slow Performance: "Temporary files, unused programs, and background processes can build up over time. If these are not managed, the computer may become slow and unresponsive."
- System Failures: "If important system updates are not installed, the computer may stop working properly. It can freeze, crash, or fail to start."
- Security Risks: "When the system or apps are not updated, harmful software like viruses can enter the computer more easily."
- Data Loss: "Without backups, important files can be lost during crashes or hardware failure."
- Hardware Damage: "Dust and overheating can damage the hardware components if the system is not cleaned or properly ventilated."
Aim for 200-300 words.
2.What is post-troubleshooting maintenance? Explain the importance of continuous maintenance with the help of the book's example.6 marks
Answer
Cover three parts:
- Post-troubleshooting maintenance (verbatim): after troubleshooting, "The next step is to learn what actions to take once the issue is resolved. This process is called post-troubleshooting maintenance. It includes additional steps that help the computer continue to work properly and avoid the same problems in the future." Its aim: keep the system "stable, secure, efficient and reliable".
- Importance of continuous maintenance (verbatim): "Solving a computer problem is only the first step. The system still needs regular care to continue working properly. Without maintenance, the same issue can happen again, or new problems may appear. Regular maintenance keeps the system stable and prevents future problems. It ensures better performance, longer life, and fewer disruptions in computer usage."
- Book example (verbatim): "If the computer becomes slow due to full storage, deleting a few files may improve its speed for a short time. However, if unnecessary files are not removed regularly or the system is not updated, the same issue may occur again."
Aim for 150-250 words.
3.What is system health monitoring? Write what built-in monitoring tools allow you to do and how regular monitoring helps users.5 marks
Answer
Cover three parts:
- Definition (verbatim): "For the smooth running of a system, it is important to check its performance regularly. This process is known as system health monitoring." Modern operating systems, such as Microsoft Windows, include built-in tools that help monitor system activity.
- The four things the tools allow (verbatim list):
- Check how much memory and processing power are being used
- Monitor background applications and services
- View system warnings and error messages
- Identify programs that may slow down the computer
- Benefit (verbatim): "Regular monitoring helps detect small issues before they become serious. By using these tools, users can take timely actions to improve performance and avoid future problems."
Aim for 120-180 words.
