TOPIC 5 COMPUTER SYSTEM HANDLING AND CARE
CONCEPT OF COMPUTER SYSTEM HANDLING AND CARE
Computer system handling and care is the practice of using computer hardware and software correctly and safely to prevent damage and ensure reliable performance. It involves following correct procedures, maintaining cleanliness, and observing safety rules.
Examples include shutting down computers properly, handling devices carefully, and keeping the computer environment clean and well ventilated.
Practical Activity
Observe how computers are handled in a school computer laboratory and list correct handling practices observed.
Scenario Activity
Explain what may happen if computers are handled carelessly in a computer laboratory.
A. HARDWARE CARE
Hardware care involves protecting the physical components of a computer system from damage caused by dust, heat, moisture, electricity, and poor handling. Proper hardware care increases the lifespan and efficiency of computer equipment.
Hardware care includes the following practices.
i. Cleaning hardware regularly.
This helps remove dust that can block ventilation and cause overheating.
ii. Protecting hardware from liquids.
Liquids can cause short circuits and permanent damage to components.
iii. Using power protection devices.
Devices such as UPS protect computers from power failure and voltage fluctuations.
iv. Handling devices gently.
Rough handling can damage internal and external components.
v. Proper placement of hardware.
Computers should be placed on stable surfaces with good ventilation.
Practical Activity
Identify and describe hardware care practices used in your school computer laboratory.
Scenario Activity
Describe the effects of dust and heat on computer hardware.
B. SOFTWARE CARE
Software care refers to the proper use, maintenance, and protection of computer programs and data to ensure smooth operation and security. Proper software care prevents system crashes, data loss, and security threats.
Software care includes the following practices.
i. Installing genuine software.
Genuine software reduces risks of malware and system instability.
ii. Updating software regularly.
Updates improve performance and fix security weaknesses.
iii. Using antivirus software.
Antivirus programs protect computers from viruses and malicious software.
iv. Backing up data.
Backups prevent data loss in case of system failure.
v. Avoiding unauthorized software
Untrusted software may introduce viruses and security risks.
Practical Activity
Check a computer and identify the antivirus software installed and whether it is updated.
Scenario Activity
Explain problems that may arise from using pirated or unauthorized software.
C. SAFE HANDLING AND PRACTICES
Safe handling and practices involve observing safety rules that protect both users and computer systems. These practices reduce accidents, injuries, and equipment damage.
Safe handling and practices include the following.
i. Electrical safety.
Users should avoid wet hands and switch off power before cleaning computers.
ii. Ergonomic safety.
Proper sitting posture and correct monitor height prevent health problems.
iii. Environmental safety.
Good lighting, ventilation, and cable arrangement reduce risks and discomfort.
iv. Proper shutdown procedures.
Correct shutdown prevents data loss and system damage. v. Keeping food and drinks away. This prevents spills that may damage hardware.
Practical Activity
Arrange a computer workstation following correct safety and ergonomic guidelines. Scenario Activity
Explain health problems that may result from poor computer handling and unsafe practices.
