9. How do multi-core processors enhance system performance?

They increase the clock speed of a single processing core

They allow multiple cores to execute instructions simultaneously

They reduce power consumption without affecting speed

They eliminate the need for RAM in the system

10. What is cache memory on a CPU, and why is it important?

Temporary storage on the CPU for fast access to frequently used data

Permanent storage for the operating system

Backup memory activated when RAM fails

External memory used only during startup

11. What does CPU stand for, and what is its primary function in a computer?

Central Processing Unit; executes instructions and performs calculations

Computer Processing Utility; manages user interfaces

Central Peripheral Unit; controls input/output devices

12. What does the term 'bus' refer to in computer architecture?

The cooling system that circulates air through the case

A pathway for data transfer between internal components

The external connections for peripheral devices

The memory cache located on the processor

13. How does a graphics processing unit (GPU) differ functionally from a CPU?

GPU handles sequential tasks; CPU handles parallel graphics rendering

GPU performs parallel operations on many data; CPU executes sequential instructions

GPU manages RAM; CPU manages storage devices

GPU controls power distribution; CPU manages cooling systems

14. What is the function of a BIOS or UEFI firmware?

Initializes hardware and loads the operating system at startup

Permanently stores all user data and applications

Manages real-time CPU clock frequency adjustments

Encrypts all data on the hard drive for security

15. The northbridge and southbridge are chipset components. What do they control?

Northbridge: RAM/GPU; Southbridge: peripherals/storage

Northbridge: cooling fans; Southbridge: power distribution

Northbridge: input devices; Southbridge: output devices

Regulates clock speeds of the processor

Manages thermal dissipation from all components

17. SSDs differ from HDDs primarily in which aspect?

SSDs use mechanical spinning disks; HDDs use flash memory

SSDs use flash memory with no moving parts; HDDs use spinning platters

SSDs can only store temporary data; HDDs store permanent data

SSDs require constant power; HDDs retain data without power

18. What is the primary purpose of a heat sink and thermal paste?

Increase CPU clock speed for better performance

Transfer heat from the CPU to the surrounding air

Insulate the CPU from electrical interference

Reduce power consumption of the processor

19. Which of the following best describes the function of a motherboard?

Main circuit board connecting all internal components via buses

Stores all permanent data and programs

Converts DC power to AC power for peripherals

Cools the CPU through liquid circulation

20. RAM is volatile memory. What does this mean for data storage?

Data persists permanently even after power loss

Data is lost immediately when power is removed

Data can only be read, not written

Data transfers at extremely high speeds
