Question 1

A UPS (uninterruptible power supply) is a device that not only provides surge protection, but also furnishes your computer with battery backup power during a power outage.

Accepted Answer

This is correct, a UPS provides both surge protection and battery backup power during a power outage.

Question 2

A microprocessor's clock speed is equal to the number of instructions it can execute in one second.

Accepted Answer

A microprocessor's clock speed is measured in Hertz (Hz) and represents the number of clock cycles per second, not the number of instructions executed. The number of instructions executed per second depends on several factors such as clock speed, instruction set architecture, pipeline depth, and more.

Question 3

A RISC processor has a complex instruction set, each requiring several clock cycles for execution.

Accepted Answer

RISC (Reduced Instruction Set Computing) processors have a simplified instruction set architecture, with each instruction typically executing in one clock cycle or less. This is in contrast to Complex Instruction Set Computing (CISC) processors, which have a larger and more complex instruction set that may require multiple clock cycles to execute.

Question 4

A keyboard is an example of a pointing device.

Accepted Answer

A keyboard is not a pointing device, it is an input device that allows users to input alphanumeric characters and other commands into a computer. Examples of pointing devices include a mouse, touchpad, or trackball which allow users to control the movement of the cursor on a screen.

Question 5

Most processors in today's personal computers use RISC technology.

Accepted Answer

The answer of Most processors in today's personal computers use...

Question 6

You can easily identify the microprocessor when looking inside a computer, as it is the only chip on the motherboard.

Accepted Answer

While the microprocessor is an important chip on the motherboard, it is not the only chip. There are also other important chips such as the chipset, memory chips, and potentially other specialized chips for certain functions.

Question 7

A card reader is a storage device that is used to read from and write to solid state storage cards, like SecureDigital (SD) and CompactFlash cards.

Accepted Answer

This statement is true. A card reader is a device specifically designed to read and write data from solid state storage cards such as SD and CompactFlash cards.

Question 8

The term form factor refers to the size and dimensions of a component, such as a system board.

Accepted Answer

The term form factor refers specifically to the size, shape, and layout of a component, particularly a system board or other internal hardware components. It is an important consideration when choosing components for a computer system or upgrading an existing system.

Question 9

A flash drive, like the one in the accompanying figure, is a portable storage device featuring a built-in connector that plugs directly into a computer s USB port.

Accepted Answer

The statement is true.

Question 10

The speed of CD, DVD and Blu-ray drives are all measured on the same scale, based upon the original 1.2 megabits per second data transfer rate of the first CD drives.

Accepted Answer

The speed of CD, DVD, and Blu-ray drives are measured on different scales, as each format has a different base data transfer rate. CD drives are based on 1.2 Mbps, DVD drives on 11.08 Mbps, and Blu-ray drives on 36 Mbps.

Question 11

A touch screen, also known as a touch-sensitive screen, can serve as both an input and output device.

Accepted Answer

A touch screen allows users to input data by touching different areas of the screen and also displays the output of that input. This makes it both an input and output device.

Question 12

An ink jet printer has a nozzle-like print head that sprays ink onto paper to form characters and graphics.

Accepted Answer

This statement is true.

Question 13

The system unit is the case that holds the main circuit boards, microprocessor, memory, power supply, and storage devices of a personal computer system.

Accepted Answer

The system unit is the primary component of a personal computer (PC) which holds many of the crucial components of the system, while other elements like the keyboard, mouse, and monitor connect to it.

Question 14

Processors with a smaller word size can process more data during each processor cycle.

Accepted Answer

Processors with a larger word size can process more data during each processor cycle.

Question 15

Currently, hard drive capacity is measured in gigabytes (GB) or terabytes (TB).

Accepted Answer

This statement is true. Hard drive capacity is currently measured in units of gigabytes (GB) or terabytes (TB).

Question 16

Currently, there are three personal computer platforms: PC, Mac, and Linux.

Accepted Answer

There are indeed three main personal computer platforms: PC, Mac, and Linux.

Question 17

RAM is volatile, which means it must constantly receive electric power to hold data.

Accepted Answer

RAM (Random Access Memory) is a type of computer memory that stores data temporarily while the computer is running. However, it is volatile, which means it requires a constant supply of electricity in order to retain the data. Once the power is turned off, the data is lost.

Question 18

A fast front side bus moves data quickly and allows the processor to work at full capacity.

Accepted Answer

A fast front side bus enables faster communication between the CPU and the rest of the system, allowing the processor to work more efficiently and at full capacity.

Question 19

DVD-RW technology allows you to write data to a disc, and then later change that data.

Accepted Answer

DVD-RW stands for "DVD-rewritable", meaning that data can be written, erased, and rewritten on the disc multiple times.

Question 20

All other things being equal, a computer with a 933 MHz processor is faster than a computer with a 2.6 GHz processor.

Accepted Answer

The computer with the 2.6 GHz processor is faster than the computer with the 933 MHz processor. This is because clock speed (measured in GHz) is one of several factors that determine a computer's overall speed. Other important factors include the number of cores, cache size, and the efficiency of the processor's architecture.
