Question 1

Input includes program instructions that the CPU receives after commands are issued by the user.

Accepted Answer

Input includes commands that are issued by the user, and those commands are processed by the CPU as program instructions.

Question 2

A keyboard changes letters,numbers,and other characters into electrical signals so the computer's processor can understand them.

Accepted Answer

This statement is true. A keyboard converts physical inputs into electrical signals, which are then processed by the computer's CPU.

Question 3

Which of the following is NOT an example of ergonomic design innovations?

Accepted Answer

Mouse pads are not typically considered an ergonomic design innovation, as they primarily serve to improve the accuracy and ease of mouse movements rather than reducing strain or discomfort for the user. Hinged keyboards, tilted screens, and wrist pads are all examples of ergonomic design features that can help to prevent or alleviate repetitive strain injuries and other ergonomic issues.

Question 4

The only data format that computers can "read" consists of binary 0s and 1s.

Accepted Answer

Computers operate in binary language, which means that they only understand and process data in the form of binary digits (0s and 1s).

Question 5

Computer-processed information consists of 0s and 1s,which need to be translated into words,numbers,sounds,and pictures.

Accepted Answer

This is correct. Computer information is stored and processed in binary code, which is represented using 0s and 1s. However, this code is translated by the computer into various forms that people can understand, such as words, numbers, sounds, and pictures.

Question 6

"Output" refers to the results of processing.

Accepted Answer

Output refers to the results of processing, such as the information displayed on a screen or printed on paper, or the sound produced by speakers.

Question 7

The mouse is a source data-entry device.

Accepted Answer

The answer of The mouse is a source data-entry device....

Question 8

An intelligent terminal has its own memory and processor,as well as a display screen and a keyboard.

Accepted Answer

An intelligent terminal has its own memory and processor, as well as a display screen and a keyboard, which allows it to perform some processing tasks independent from the host computer.

Question 9

Tactile keyboards are also called virtual keyboards.

Accepted Answer

Tactile keyboards are physical keyboards that have tactile feedback, while virtual keyboards are digital or touch screen keyboards that do not have tactile feedback.

Question 10

(p.249 [art])
A webcam is an example of an input device.

Accepted Answer

A webcam is a device that captures video and audio inputs, making it an input device.

Question 11

Which of the following is NOT a type of nonimpact printer?

Accepted Answer

Ink-jet, laser, and thermal printers are all types of nonimpact printers. Dot-matrix printers are impact printers because they use a print head that strikes an ink ribbon to create text or images.

Question 12

A terminal that consists of a display screen and a keyboard and that has the ability to input and output but does not have the ability to process data is called a dead terminal.

Accepted Answer

A dead terminal is a terminal that does not have the ability to input or output data. A terminal that can input and output data but cannot process it is called a dumb terminal.

Question 13

People who use keyboards a lot may suffer from which physical problem?

Accepted Answer

People who use keyboards a lot may suffer from carpal tunnel syndrome, which is caused by repetitive motions and pressure on the median nerve in the wrist. Computer vision syndrome is caused by too much screen time, ergonomic syndrome is not a recognized medical condition, and electromagnetic syndrome is a controversial condition with no scientific evidence to support it.

Question 14

Using a computer screen with poor resolution or glare problems could cause which problem?

Accepted Answer

Poor resolution or glare problems on a computer screen can cause computer vision syndrome, which includes symptoms such as eye strain, headaches, blurred vision, and dry eyes. Carpal tunnel syndrome and repetitive stress injuries are typically caused by poor ergonomics or overuse of the hands and wrists on a keyboard or mouse. Electromagnetic syndrome is not a recognized medical condition.

Question 15

Which device prints large,three-dimensional high-quality color graphics?

Accepted Answer

A plotter is used to print large, three-dimensional high-quality color graphics, often used for architectural designs, engineering drawings, and other similar applications. A spooler manages the queue of print jobs, but does not print anything itself. Thermal and laser printers are not typically used for large, three-dimensional graphics.

Question 16

The concept of creating safer and more efficient equipment is called __________.

Accepted Answer

The concept of creating safer and more efficient equipment is called ergonomics, which focuses on designing equipment and workspaces to fit the needs and capabilities of people. Prudent avoidance refers to avoiding exposure to potential hazards, while product design and workplace design are more general terms that can encompass a variety of considerations beyond just safety and efficiency.

Question 17

Most keyboards are Dvorak keyboards.

Accepted Answer

Most keyboards are QWERTY keyboards, not Dvorak keyboards, which are a less commonly used alternative keyboard layout.

Question 18

Input refers to information sent to the screen or the printer or to be stored on disk.

Accepted Answer

Input refers to data or signals that are sent to a computer for processing, not the information sent to output devices like screens or printers or for storage.

Question 19

Devices that translate data into a form the computer can process are called output hardware.

Accepted Answer

Devices that translate data into a form that humans can perceive are called output hardware. Examples of output hardware include monitors, speakers, and printers.

Question 20

Laser printers use a particular type of software to lay out pages and control how pages look; this software is called __________.

Accepted Answer

Laser printers use page description languages (PDLs) to lay out pages and control how pages look. Examples of PDLs include PostScript and PCL (Printer Command Language). Page resolution refers to the number of dots per inch (dpi) that a printer can produce, feathering refers to the softening of image edges, and PDF is a type of file format commonly used for digital documents.
