Question 1

Platform as a Service is also known as a virtual desktop.

Accepted Answer

Platform as a Service (PaaS) is a cloud computing model where the provider offers a platform for developers to build, run, and manage applications. It is not the same as a virtual desktop, which is a technology that allows users to remotely access and control a desktop computer or operating system from another device.

Question 2

A heat sink is a small ceramic or metal component with fins on its surface that absorbs and disperses heat produced by electrical components such as a processor.

Accepted Answer

This is a correct definition of a heat sink.

Question 3

Registers are part of the memory.

Accepted Answer

Registers are small storage locations within the CPU, not part of the main memory, used for quick data access and processing.

Question 4

In the machine cycle, executing is the process of carrying out commands.

Accepted Answer

Executing is indeed the process of carrying out commands in the machine cycle.

Question 5

In the machine cycle, fetching refers to the process of translating instructions into signals the computer can execute.

Accepted Answer

Fetching refers to retrieving an instruction or data from memory, not translating it into executable signals.

Question 6

The speed of the system clock has a significant effect on peripheral devices such as a printer or disk drive.

Accepted Answer

Peripheral devices like printers or disk drives operate independently of the system clock speed, as they have their own processing and timing mechanisms.

Question 7

On a personal computer, the various functions performed by the processor extend over many separate chips and often multiple circuit boards.

Accepted Answer

On a personal computer, the various functions performed by the processor are integrated into a single chip known as the CPU (central processing unit). The CPU is usually located on the motherboard of the computer and does not require multiple circuit boards.

Question 8

The electronic components and circuitry of the system unit, such as the processor and memory, usually are part of or are connected to a circuit board called the fatherboard.

Accepted Answer

The correct term for the circuit board is "motherboard," not "fatherboard."

Question 9

In the machine cycle, decoding is the process of obtaining a program instruction or data item from memory.

Accepted Answer

Decoding is the process of interpreting the fetched instruction, not obtaining it from memory. Fetching is the step where the instruction or data is obtained from memory.

Question 10

Liquid cooling technology uses a continuous flow of fluid(s) in a process that transfers the heated fluid away from the processor to a radiator-type grill, which cools the liquid, and then returns the cooled fluid to the processor.

Accepted Answer

Liquid cooling technology is designed to transfer heat away from the processor using a flow of fluid that is continuously circulated through a loop. This process typically involves a radiator or heat exchanger that cools the liquid before it is recirculated through the loop, thereby helping to keep the processor and other components cool. Overall, liquid cooling can offer better cooling performance and reduced noise compared to traditional air-cooling solutions.

Question 11

Processors all use the same type of register.

Accepted Answer

Processors can use different types of registers depending on their architecture and design. For example, some processors may have specialized registers dedicated to specific tasks such as floating-point operations or memory management.

Question 12

Multi-core processor speed performance increases are especially noticeable when users are running multiple programs simultaneously.

Accepted Answer

Multi-core processors allow for better multitasking capabilities, as each core can handle a separate task. When users run multiple programs simultaneously, the workload is spread across the cores, resulting in faster overall performance.

Question 13

Together, the four basic operations on a processor (fetching, decoding, executing, and storing) comprise a pipeline cycle.

Accepted Answer

The answer of Together, the four basic operations on a...

Question 14

Custom-built computers often do not include recovery media to restore the computer in the event it fails.

Accepted Answer

This is often true, as custom-built computers are typically assembled by individual users or smaller computer shops, and may not come with the same pre-installed software and recovery options as larger manufacturers. It is important for users to create their own recovery media or backup their system to ensure they can restore it in the event of a failure.

Question 15

Data needed by programs and applications enters memory from either an input device or a storage device.

Accepted Answer

Programs and applications require data to be loaded into memory in order to be executed, which can come from an input device like a keyboard or mouse, or from a storage device like a hard drive or flash drive.

Question 16

The case of the system unit is made of metal or plastic and protects the internal electronic components from damage.

Accepted Answer

The case or chassis of the system unit is typically made of metal or plastic and serves as a protective enclosure for the internal electronic components, helping to prevent damage from dust, moisture, or physical impacts.

Question 17

Each processor core on a multi-core processor generally runs at a faster speed than a single-core processor.

Accepted Answer

Multi-core processors do not necessarily have faster individual cores compared to single-core processors; they are designed to handle multiple tasks simultaneously rather than increasing the speed of individual cores.

Question 18

A dual-core processor doubles the processing speed of a single-core processor.

Accepted Answer

A dual-core processor does not necessarily double the processing speed of a single-core processor. It can improve performance in certain applications that can take advantage of multiple processing cores, but the speed increase is not a direct doubling.

Question 19

The speed of the system clock is one of the factors that influences a computer's performance.

Accepted Answer

The speed of the system clock determines how fast the processor can execute instructions, which directly affects the overall performance of the computer. A higher clock speed means that the processor can complete more tasks per second, resulting in faster performance. However, it is not the only factor that influences a computer's performance. Other factors such as the number of cores, size of cache memory, and efficiency of instruction execution also play a significant role.

Question 20

A vendor of a custom-built computer will always offer the same service packages and warranty support as the vendor of a mass-produced computer.

Accepted Answer

This is false as custom-built computer vendors often provide more extensive service packages and warranty support compared to vendors of mass-produced computers. This is because they have more control over the components used and are often able to offer personalized support for each custom-built system.
