What is the purpose of defragmenting a hard drive?

• To defragment the operating system

• To increase the risk of data loss

• To reduce the lifespan of the hard drive

• To optimize storage space and improve system performance.

Explain the difference between RAM and ROM.

• RAM and ROM are interchangeable

• RAM is used for permanent storage and ROM is used for temporary storage

• RAM is non-volatile and ROM is volatile

• RAM is volatile and used for temporary storage, while ROM is non-volatile and used for permanent storage.

What is BIOS and what is its function in a computer system?

• BIOS is a software application that enhances graphics performance in a computer system.

• BIOS is firmware that initializes hardware components during the boot process and provides the computer with basic operational functions.

• BIOS is a type of computer virus that corrupts system files.

• BIOS is a physical component that stores user data in a computer system.

How can you troubleshoot a computer that is not powering on?

• Troubleshoot by checking power connections, testing power supply, inspecting motherboard, and booting with minimal components.

• Hit the computer to see if it starts

• Shout at the computer to motivate it to turn on

• Pour water on the computer to cool it down

What is the role of a CPU in a computer system?

• Provides power to a computer system.

• Manages the operating system of a computer system.

• Stores data in a computer system.

• Executes instructions and performs calculations in a computer system.

Describe the steps involved in cleaning a computer's internal components.

• Pouring water on the components

• Cleaning with a corrosive liquid

• Using a vacuum cleaner directly on the parts

• The steps involved in cleaning a computer's internal components include shutting down the computer, opening the case, using compressed air, cleaning with a brush or cotton swabs, removing components if needed, reassembling, and checking for performance improvements.

What is the importance of updating device drivers?

• Updating device drivers is crucial for system compatibility, stability, security, and performance.

• Updating device drivers is unnecessary and can cause system issues

• Security is not a concern when it comes to updating device drivers

• Device drivers do not impact system performance

Explain the concept of thermal paste and its use in computer systems.

• Thermal paste is only necessary for laptops, not desktops

• Thermal paste is used in computer systems to improve heat transfer between the CPU/GPU and the heat sink by filling in microscopic gaps and air pockets.

• Thermal paste is applied on the outside of the CPU/GPU

• Thermal paste is used to increase the speed of the computer system

What are the common signs of a failing hard drive?

• Strange noises, frequent crashes or error messages, slow performance, disappearing files, bad sectors

• Blue screen of death, overheating, loud fan noises

How can you prevent overheating in a computer system?

• Ensure proper ventilation, clean dust, use cooling pad, avoid blocking air vents, monitor temperature.

• Place the computer on a soft surface

• Increase the room temperature

• Cover the computer with a blanket
