A.) IBM invented the floppy disk drive
B.) There is a switch on the disk which controls the write protection
C.) Magnets can cause you to lose data on the floppy disk
D.) Floppy disk drive is more reliable than flash storage

2. Question

2.) Which fact about overclocking is NOT correct?

A.) Overclocking can reduce the lifespan of the component
B.) Overclocking can reduce the system's stability
C.) Overclocking can increase the system's temperature
D.) Overclocking is guaranteed to double the systems performance

3. Question

3.) What is the benefit of thermal compound paste?

A.) It stops the heat sink from falling off the processor
B.) It prevents the processor from burning up
C.) It creates better contact between the chip and surface area of the heat sink
D.) It helps only if you have a copper plated heat sink

4. Question

4.) Thomas has installed a heat sink on his processor but has forgotten to apply thermal compound paste. What will likely happen when he powers his computer on?

A.)The computer will overheat and stop working posing and poses a high risk to other components.
B.) The computer will not start up without the compound paste.
C.) The processor temperature would be only slightly higher, but the system would still work as intended.
D.) You risk the computer catching on fire

5. Question

5.) Which of the follow interfaces allows both video and audio data to be sent through a single cable?

A.) DVI
B.) HDMI
C.) VGA
D.) S-video

6. Question

6.) John’s temperature monitor in the bios indicates that his CPU is overheating. Which fan is likely to contain the fault?

A.) 80mm rear fan, behind the CPU
B.) 80mm side fan, adjacent to the CPU
C.) 120mm front fan, below the chassis
D.) 80mm heat sink and fan, on top of the CPU

7. Question

7.) Sandy is thinking of upgrading his CPU from a single core to a quad core. What are the disadvantages of this upgrade?

A.) Supported application performance will increase
B.) Quad core processors tend to operate at a higher temperature at load, thus increasing the temperature within the chassis and other components within
C.) The quad core processor might be too fast for the applications used
D.) There are no disadvantages because quad core is simply better than single core in all respects.

8. Question

8.) What is the advantage to sticking with a single core opposed to a quad core?

A.) Quad cores are four times more expensive than a single core processor
B.) Quad core is a gimmick and are not that much faster than single core
C.) You need a single core processor to run other applications and games
D.) The power consumption is lower, lower temperatures, lower electricity bill

9. Question

9.) What is the purpose of the processors cache?

A.) The CPU cache reduces the amount of time the processor has to fetch data from the main memory
B.) The CPU cache reduces the amount of time the processor has to fetch data from the Hard Disk Drive
C.) The CPU cache is designed to replace the main memory completely.
D.) The CPU cache and main memory serve the same purpose, they just happen to be located in difference places.

10. Question

10.) The AMD Phenom processor has three levels of independent cache. Which cache type is the fastest?

A.) L1 cache
B.) L2 cache
C.) L3 cache
D.) A and B
