Question 1

Processors all use the same type of register.

Accepted Answer

Different processors can have different types and sizes of registers.

Question 2

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

Accepted Answer

Multi-core processors have the ability to run multiple programs simultaneously, which results in faster performance compared to single-core processors. This is because each core can handle a different task, allowing for more efficient processing power.

Question 3

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 does indeed use a continuous flow of fluid to transfer heat away from the processor and cool it before returning the cooled fluid to the processor.

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

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 run, which can come from input devices such as a keyboard or mouse, or from storage devices such as a hard drive or flash drive. This data then enters the computer's memory for processing.

Question 6

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

Accepted Answer

Platform as a Service (PaaS) is a cloud computing model that provides a platform for developers to build, run and manage applications without the need for infrastructure maintenance. It is not the same as a virtual desktop.

Question 7

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

Accepted Answer

A dual-core processor can handle multiple tasks simultaneously but it does not necessarily double the processing speed of a single-core processor. The actual improvement in processing speed depends on several factors such as the type of tasks being performed and the overall system configuration.

Question 8

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 translating a program instruction into signals that the computer can execute, not obtaining it from memory. Obtaining the instruction from memory is typically referred to as the "fetch" step.

Question 9

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

A vendor of a custom-built computer may offer different service packages and warranty support compared to a vendor of a mass-produced computer as the custom-built computer vendor may have different policies and resources.

Question 10

Registers are part of the memory.

Accepted Answer

The answer of Registers are part of the memory....

Question 11

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

Accepted Answer

The speed of the system clock primarily affects the CPU and memory operations, not peripheral devices like printers or disk drives, which rely on their own controllers and interfaces for speed regulation.

Question 12

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

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

Question 13

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

Accepted Answer

Custom-built computers are assembled from individual components, and the manufacturer of each component provides their own warranty and recovery options. Therefore, it is up to the user to create their own recovery media or purchase it separately.

Question 14

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, measured in gigahertz (GHz), determines the rate at which the computer can process instructions and affects overall performance. A faster clock speed can result in faster processing times and improved performance.

Question 15

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

Accepted Answer

The four basic operations (fetching, decoding, executing, and storing) describe the steps of the instruction cycle or execution cycle, not a pipeline cycle. Pipelining is a technique where multiple instruction cycles are overlapped in execution, but it is not itself comprised of these four steps.

Question 16

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

Accepted Answer

Fetching in the machine cycle refers to the process of retrieving an instruction from program memory.

Question 17

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 the "motherboard," not "fatherboard."

Question 18

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 onto a single chip known as the Central Processing Unit (CPU). The CPU is often accompanied by other chips on the same circuit board, such as memory and graphics processing units.

Question 19

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

Accepted Answer

Multi-core processors allow for parallel processing, which can improve overall performance, but each individual core does not necessarily run faster than a single-core processor; the speed of a core is determined by its architecture and clock speed, not the number of cores.

Question 20

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

Accepted Answer

The case of the system unit is indeed made of metal or plastic and serves as a protective covering for the internal electronic components.
