Question 1

When bytes are used to represent a finite set of data such as the 52 cards in a deck, a table can be used to associate each unit of data with a unique bit pattern.

Accepted Answer

A table can map each card to a unique bit pattern, allowing bytes to represent each card in the finite set.

Question 2

Computer programmers can assign bytes to represent anything by designing a look-up table.

Accepted Answer

Programmers can create a look-up table to map byte values to specific meanings or representations, allowing them to assign bytes to represent anything they choose.

Question 3

The decimal number system, also called base 10, was adopted by humans because of its ease of use for our 10-fingered species.

Accepted Answer

The decimal system likely became prevalent because humans have ten fingers, making it intuitive to count in tens.

Question 4

Digitized information is valueless without the ability to process it into useful forms.

Accepted Answer

Digitized information needs to be processed and analyzed to extract meaningful insights and make informed decisions, otherwise it remains just raw data.

Question 5

Any object having at least one distinct state can be used as a digital switch.

Accepted Answer

The answer of Any object having at least one distinct...

Question 6

When electricity is flowing through a transistor it represents a 0; when it is not flowing it represents a 1.

Accepted Answer

In digital electronics, a flowing current typically represents a binary 1, while no current represents a binary 0.

Question 7

Intel, AMD, and other manufacturers are manufacturing dual-core processors and quad-core processors that use two and four CPUs on one chip that work together to provide twice and four times the speed of traditional single-core chips.

Accepted Answer

Dual-core and quad-core processors use multiple CPUs on a single chip to provide increased speed compared to traditional single-core chips.

Question 8

Data flows back and forth between the CPU and RAM across the rear side bus.

Accepted Answer

The data flows between the CPU and RAM across the front side bus (FSB), not the rear side bus.

Question 9

Typically the FSB connects to a chipset that ties together several bus systems sending and receiving bytes from memory, input and output devices, storage, networks, and other motherboard components.

Accepted Answer

The Front Side Bus (FSB) is a critical component in a computer's architecture, connecting the CPU to the main memory and other components via the chipset, facilitating communication between them.

Question 10

Faster clock speeds do not mean that a device will generate more heat and require a larger cooling system.

Accepted Answer

Higher clock speeds typically result in increased power consumption and heat generation, necessitating more robust cooling solutions to maintain optimal operating temperatures.

Question 11

A processor with a 32-bit wordlength has the capacity to be twice as fast as a processor with an 8-bit wordlength.

Accepted Answer

The speed of a processor is not solely determined by its word length; it also depends on other factors such as clock speed, architecture, and efficiency.

Question 12

The truest measure of a processor's performance is how well it integrates with the computer's memory.

Accepted Answer

Processor performance is typically measured by factors like clock speed, core count, and instructions per cycle, not just memory integration.

Question 13

ROM is sometimes called memory or primary storage.

Accepted Answer

ROM (Read-Only Memory) is a type of non-volatile storage that is used to store firmware or software that is rarely changed, and it is not considered primary storage, which typically refers to RAM (Random Access Memory).

Question 14

On notebook systems, the graphics hardware is typically in the form of a separate graphics card that you can remove or upgrade.

Accepted Answer

Most notebook systems have integrated graphics hardware that is built into the motherboard or CPU, making it non-removable and not easily upgradeable.

Question 15

Because both the processor and RAM require electricity to store data, both contain only minimal data when a computer is initially powered up.

Accepted Answer

The answer of Because both the processor and RAM require...

Question 16

CMOS is the reason that a PC is able to maintain the correct time and date even when it is powered down.

Accepted Answer

The CMOS (Complementary Metal-Oxide-Semiconductor) chip stores the system's time and date settings, and it is powered by a small battery, allowing it to keep track of time even when the computer is turned off.

Question 17

Two types of media use magnetic storage: disks and tapes.

Accepted Answer

Magnetic storage is used in both hard disk drives (HDDs) and magnetic tape drives, which store data by magnetizing a medium.

Question 18

Just like the ROM on your motherboard, once data has been recorded on a CD-ROM, it cannot be modified-the disc is read-only.

Accepted Answer

CD-ROM stands for Compact Disc Read-Only Memory, meaning data written on it cannot be altered or erased, similar to the ROM on a motherboard.

Question 19

Besides their use in performing mathematical calculations, base ten numbers are the key ingredient for digitizing sound, music, photographs, drawings, paintings, animation, and movies. _________________________

Accepted Answer

binary

Question 20

On the road, digital convergence takes the form of smart phones and other multipurpose handheld devices that merge cell phone, PDA, MP3 player, digital video player, and digital camera functionality into a single portable device. _________________________

Accepted Answer

Digital convergence refers to the merging of previously distinct technologies into a single device, and smartphones exemplify this by combining multiple functionalities such as communication, media playback, and photography.
