Question 1

COGNITIVE ASSESSMENT What is unique about a multi-core processor?

Accepted Answer

A multi-core processor is unique because it is a single chip that contains two or more separate processor cores, allowing for parallel processing and improved performance.

Question 2

Which of the following is an alternate term for an adapter card?

Accepted Answer

An expansion card is a hardware component which is added to a computer system to increase its capabilities. It is also referred to as an adapter card because it adapts a certain hardware component such as a graphics card, sound card or network card to the computer's motherboard. The other options, router and register are not synonyms for adapter card. A bus card is not a commonly used term.

Question 3

COGNITIVE ASSESSMENT When your friend opened the case containing the electronic components of his computer, he saw the main circuit board for the computer. What is this circuit board called?

Accepted Answer

The main circuit board in a computer is commonly known as the "motherboard." It is the central hub that connects all the components of the computer, allowing them to communicate with each other.

Question 4

Which of the following is the International Electronics Commission working to make the universal connector standard for charging mobile devices?

Accepted Answer

The International Electronics Commission has already made micro USB the universal connector standard for charging mobile devices.

Question 5

COGNITIVE ASSESSMENT What are three names for the electronic component that interprets and carries out the basic instructions that operate a computer?

Accepted Answer

The CPU, processor, and central processing unit are all names for the electronic component that interprets and carries out the basic instructions that operate a computer.

Question 6

COGNITIVE ASSESSMENT When a user runs an application, what transfers from a storage device to memory?

Accepted Answer

Instructions are transferred from a storage device to memory when a user runs an application, as they are needed for the CPU to execute the program.

Question 7

Which of the following adapter cards connects to musical instruments?

Accepted Answer

MIDI (Musical Instrument Digital Interface) is a protocol used for connecting electronic musical instruments to computers and other devices. USB, serial, and parallel are not specific to musical instruments and have a variety of uses.

Question 8

Which of the following is the component of the system unit that converts the wall outlet AC power into the DC power a computer requires?

Accepted Answer

The power supply is responsible for converting AC power from the wall outlet into DC power that the computer can use. The other options are not components of the power supply.

Question 9

COGNITIVE ASSESSMENT What are the roles of the control unit and the ALU?

Accepted Answer

The control unit directs the operations of the ALU by fetching instructions from memory, decoding them, and then directing the ALU to perform the necessary arithmetic or logical operations.

Question 10

COGNITIVE ASSESSMENT If a dog is identified by scanning the shoulder or neck of the animal, what provides the information about the dog?

Accepted Answer

A microchip implanted in the dog provides information when scanned, typically located in the shoulder or neck area.

Question 11

On which of the following does battery life depend?

Accepted Answer

Battery life depends on usage, as the more a device is used, the more energy it will consume and the quicker the battery will run out. Indices and dimensionality are not relevant factors and resolution may have a minor impact on battery life, but not as much as usage.

Question 12

Within the circuitry of a computer, each channel along which bits transfer allows the various devices both inside and attached to the system unit to communicate with each other. What are these channels, shown in the accompanying figure, called?

Accepted Answer

The answer of  Within the circuitry of a computer,...

Question 13

COGNITIVE ASSESSMENT In your engineering class, you are required to calculate the approximate size of a series of chips. Which of the following is true?

Accepted Answer

Most chips are no bigger than one-half-inch square.

Question 14

Which of the following determines the number of bits that the computer can transmit at one time?

Accepted Answer

The bus width determines the number of bits that the computer can transmit at one time.

Question 15

What is the unit of measurement for the clock speed for the channel shown in the accompanying figure?

Accepted Answer

The answer of  What is the unit of measurement...

Question 16

COGNITIVE ASSESSMENT Which of the following is NOT true of the new multi-core processor you have just purchased?

Accepted Answer

Each processor core on a multi-core processor does not necessarily run at a faster speed than a single-core processor; the advantage lies in handling multiple tasks simultaneously, not in individual core speed.

Question 17

How many fans are typically in a desktop case?

Accepted Answer

A typical desktop case will have at least three fans for proper ventilation and cooling- one at the front, one at the back, and one on the power supply. Some cases may have additional fans on the side, top, or bottom for better airflow. A single fan or even two may not provide enough cooling for the components inside the case, leading to overheating and potentially damaging the hardware. Six fans may be excessive for a typical desktop case and not necessary for efficient cooling.

Question 18

COGNITIVE ASSESSMENT You are going to purchase a mass-produced computer from your local computer store. Which of the following is likely a component you can customize?

Accepted Answer

The answer of COGNITIVE ASSESSMENT You are going to purchase...

Question 19

Which of the following allows the processor to communicate with peripheral devices?

Accepted Answer

The expansion bus allows the processor to communicate with peripheral devices such as graphics cards, sound cards, and network adapters. The other options (index bus, interpolated bus, and power bus) are not commonly used components in computer architecture.

Question 20

COGNITIVE ASSESSMENT When you examine a computer chip under a microscope, what will you see?

Accepted Answer

Integrated circuits are what you would see when examining a computer chip under a microscope, as they are the essential components that make up the chip.
