Question 1

Accessing data from the hard drive to send to the CPU is faster than accessing data from RAM.

Accepted Answer

Accessing data from RAM is much faster than accessing data from the hard drive due to the physical proximity of RAM to the CPU and the much faster transfer rates between RAM and the CPU.

Question 2

Dolby Digital 7.1 requires a total of eight speakers.

Accepted Answer

Dolby Digital 7.1 requires eight discrete speaker channels: front left, center, front right, surround right, surround left, back surround right, back surround left, and low-frequency effects (LFE).

Question 3

Cache memory is a form of ROM.

Accepted Answer

Cache memory is a form of volatile memory, unlike ROM which is non-volatile.

Question 4

3D sound is different from surround-sound.

Accepted Answer

3D sound refers to sound that is more immersive and can be perceived as coming from all directions, including above and below, whereas surround-sound typically refers to sound that is coming from specific speakers arranged around the listener.

Question 5

RAM prices tend to be very stable.

Accepted Answer

RAM prices can be subject to fluctuations and can increase or decrease depending on factors such as demand, supply, and production costs.

Question 6

When using multiple monitors, you must have multiple video cards.

Accepted Answer

You can also use a single video card with multiple outputs to use multiple monitors. Alternatively, some laptops have the ability to connect to multiple external monitors without needing a separate video card.

Question 7

RAID 0 automatically duplicates your data and saves it on two identical drives.

Accepted Answer

RAID 0 does not duplicate data, instead it splits data evenly across two or more drives for improved performance.

Question 8

If you reformat the hard drive on a computer, it erases all personal information from your computer and makes it safe to donate.

Accepted Answer

Reformatting a hard drive does not securely erase all personal information; data can still be recovered with special software. To safely donate, use a tool designed to securely wipe the drive.

Question 9

Level 1 cache usually contains the least amount of storage of the cache memory levels.

Accepted Answer

This is true. Level 1 cache typically has the smallest storage capacity among the cache memory levels, but it is also the fastest in terms of speed as it is directly integrated into the processor.

Question 10

Optical discs store data using tiny pits and grooves burned by a laser.

Accepted Answer

This statement is true. Optical discs, such as CDs, DVDs, and Blu-ray discs, use a laser to burn tiny pits and grooves onto the disc's surface, which can be read by a laser to retrieve the stored data.

Question 11

Video cards are designed with their own RAM storage.

Accepted Answer

Video cards come with dedicated RAM storage to process and render complex graphical data. This dedicated RAM is also known as VRAM (Video RAM) or GDDR (Graphics Double Data Rate) memory.

Question 12

The heads of a mechanical hard disk drive touch the surface of the platter to read or write the data.

Accepted Answer

The heads of a mechanical hard disk drive float just above the surface of the platter on a cushion of air created by the spinning of the platters, and do not physically touch the surface to read or write data.

Question 13

The use of multiple cores on one CPU chip allows the execution of two or more sets of instructions at the same time.

Accepted Answer

The use of multiple cores on one CPU chip allows for parallel processing, which allows for multiple sets of instructions to be executed simultaneously. Each core can handle a separate thread or process, improving overall system performance.
