The answer of  In the accompanying figure, the microprocessor...

Question 2

Sequential access is the ability of a device to "jump" directly to requested data.

Accepted Answer

Sequential access refers to accessing data in a linear, sequential manner. It does not allow for direct jumping to specific requested data like random access does.

Question 3

The term ____ designates equipment that might be added to a computer system to enhance its functionality.
A) digital device
B) system add-on
C) disk pack
D) peripheral device

Accepted Answer

Peripheral devices are external components added to a computer system to enhance its functionality. Digital devices are a broad category that includes both internal and external computer components, while system add-ons may refer to software or firmware updates. Disk packs specifically refer to a type of storage device.

Question 4

Access time is the amount of data a storage device can move each second from the storage medium to the computer.

Accepted Answer

Access time refers to the time it takes for the storage device to locate and retrieve data from the storage medium. It is measured in milliseconds (ms) or microseconds (μs), not in the amount of data per second. The amount of data that can be transferred per second is referred to as data transfer rate.

Question 5

The main component of a typical desktop computer is the ____, which houses the processor, memory, some storage devices, and display and sound circuitry.
A) kiosk
B) system unit
C) form factor
D) platform

Accepted Answer

The system unit is the primary component of a desktop computer and contains the main processing unit (CPU), memory, and storage devices, as well as display and sound circuitry. The other options - kiosk, form factor, and platform - are not the primary component of a desktop computer.

Question 6

The number of horizontal and vertical pixels that a device displays on a screen is referred to as its resolution .

Accepted Answer

The definition of resolution refers to the number of horizontal and vertical pixels that a device displays on a screen. Therefore, the statement is true.

Question 7

Storage mass is the maximum amount of data that can be stored on a storage medium.

Accepted Answer

The answer of Storage mass is the maximum amount of...

Question 8

The more data and programs that can fit into EEPROM , the less time your computer will spend moving data to and from virtual memory.

Accepted Answer

The answer of The more data and programs that can...

Question 9

CDs and DVDs are examples of magnetic storage media.

Accepted Answer

CDs and DVDs are actually examples of optical storage media, which use lasers to read and write data. Magnetic storage media includes devices such as hard drives and floppy disks.

Question 10

On a display device the refresh rate is the distance in millimeters between like-colored pixels, and is a measure of image clarity.

Accepted Answer

The refresh rate on a display device refers to the number of times per second the image is refreshed, not the distance between like-colored pixels. The distance between like-colored pixels is called the pixel pitch or pixel density.

Question 11

Internal drive bays can easily detach from the system unit.

Accepted Answer

Internal drive bays are built into the system unit and cannot be easily detached.

Question 12

The term ____ refers to the size and dimensions of a computer component.
A) form factor
B) system specification
C) disk header
D) peripheral metric

Accepted Answer

The term "form factor" specifically refers to the size and dimensions of a computer component, such as a motherboard or power supply. The other options are not directly related to size and dimensions.

Question 13

In the accompanying figure, expansions slots are shown in picture D .

Accepted Answer

The accompanying figure shows a picture labeled as D, in which we can see expansion slots. Hence, the statement is true.

Question 14

In the accompanying figure, the connection between pictures A and B represents the expansion bus.

Accepted Answer

The answer of  In the accompanying figure, the connection...

Question 15

A ____ computer is a small, lightweight personal computer with screen, keyboard, storage, and processing components integrated into a single unit.
A) tower
B) tablet
C) desktop
D) portable

Accepted Answer

A portable computer is a small, lightweight personal computer with integrated components, designed for easy transport and use in various locations.

Question 16

The microprocessor is the most important component of a computer, and usually the most expensive single component.

Accepted Answer

The microprocessor is indeed the most important component of a computer as it performs most of the calculations and controls the overall functioning. It is also usually the most expensive component.

Question 17

____ are the form factor of choice for computer owners who might want to upgrade components in the future because it is easy to get inside the case and swap out parts.
A) Cube units
B) Base units
C) Tower units
D) Minicases

Accepted Answer

Tower units are usually larger and have more internal space compared to other form factors, making it easier for users to access the internal components and upgrade them. Cube and minicases are smaller and cramped, while base units may not be designed with upgradeability in mind.

Question 18

RAM circuitry holds "hard-wired" instructions that are a permanent part of the circuitry.

Accepted Answer

RAM circuitry stores data temporarily and is not designed to hold permanent instructions. Instead, read-only memory (ROM) is used to hold hard-wired instructions.

Question 19

EIDE, Ultra ATA, SCSI and DMA refer to the different types of controllers used by a hard disk drives.

Accepted Answer

These are indeed the different types of controllers used by hard disk drives.

Question 20

RAM speed is often expressed in nanoseconds (ns) or megahertz (MHz).

Accepted Answer

RAM speed can be measured in terms of latency (nanoseconds) or frequency (megahertz), indicating how quickly it can access data and how many cycles per second it can perform, respectively.
