Accepted Answer

Digital whiteboards connect to computers and allow for the projection of computer output. They also come with a special pen that can be used to control the computer. Active display areas and flat-panel monitors are types of displays and do not necessarily have the ability to connect to a computer or be controlled with a special pen. E-book readers are devices used for reading books and do not have the functionality to connect to a computer or project output.

Question 7

Which of the following have sensors that collect data about your hand movements?

Accepted Answer

VR controllers typically have sensors that track your hand movements, allowing for more immersive interaction with virtual environments. The other options listed do not typically involve hand movement tracking.

Question 8

________ printers use a technology similar to that used in a photocopying machine.

Accepted Answer

Laser printers use a technology where toner (powdered ink) is fused onto paper using heat and pressure, similar to how a photocopying machine works.

Question 9

Supermarkets use ________ to scan codes printed on product containers.

Accepted Answer

Supermarkets use bar code readers to scan the codes printed on product containers. Bar codes are a series of vertical lines of varying width and spacing that represent a specific product and manufacturer. The bar code reader uses photoelectric cells to detect the bars and spaces of the code and translates it into information about the product. OCR readers are used to recognize and read characters in text, not bar codes, and RFID microchips are a type of wireless identification technology that uses radio frequency to communicate information, but not all product containers have RFID microchips. Therefore, the best choice is B, bar code readers.

Question 10

Two categories of laser printers are ________.

Accepted Answer

The two categories of laser printers are typically classified as personal and shared. Personal laser printers are designed for individual use, while shared laser printers are designed for use by multiple users or in an office setting. The other options (A, C, and D) do not accurately classify types of laser printers.

Question 11

Flatbed,document,and portable are types of ________ that accept documents and convert them into machine-readable form.

Accepted Answer

Optical scanners are devices that accept documents and convert them into machine-readable form. The flatbed, document, and portable are all types of optical scanners. Recognition devices may refer to a broader category of devices that include optical scanners, but it is not specific enough to be the correct answer. Coprocessors and RFID readers are not related to optical scanners.

Question 12

________ printers are widely used with ATMs.

Accepted Answer

Thermal printers are commonly used with ATMs because they are fast, reliable, and have low operating costs. They also produce high-quality prints that are easy to read and require minimal maintenance. Dot-matrix printers were previously used with ATMs, but they have largely been replaced by thermal printers because they are slower and produce lower quality prints. Cloud and laser printers are not commonly used with ATMs.

Question 13

Which of the following statements is incorrect?

Accepted Answer

Printer speed is typically measured in pages per minute (ppm) or images per minute (ipm), not in the number of words printed per minute.

Question 14

Which of the following printer features enables you to print on both sides of a sheet of paper?

Accepted Answer

Duplex printing allows you to print on both sides of a sheet of paper. Simplex printing only prints on one side, resolution refers to the quality of the printed image, and dual matrix is not a printer feature.

Question 15

The most widely used audio-output devices.

Accepted Answer

Speakers and headphones are the most widely used audio-output devices as they allow individuals to listen to music, watch videos, and communicate through various digital platforms. Microphones are input devices that capture sound, while cloud printers and faxes are output devices for printing and sending documents, respectively.

Question 16

The most common card reader is the ________ card reader which reads encoded information stored on a thin magnetic strip located on the back of the card.

Accepted Answer

Magnetic card readers are the most common type of card reader that are used to read information encoded on the magnetic strip located on the back of the card. Bar code readers are used to scan bar codes, QR code readers are used to scan QR codes, and OCR readers are used to recognize and convert printed or written text into digital text.

Question 17

________ recognition is often used to score standardized multiple-choice tests.

Accepted Answer

Optical-mark recognition (OMR) is a technology that detects marks on standardized forms such as multiple-choice test answer sheets. OMR can quickly and accurately read the marks made by students and score the tests accordingly. Magnetic ink character recognition (MICR) is used to read checks and other financial documents, radio frequency identification (RFID) is used for tracking inventory and assets, and optical-character recognition (OCR) is used to read printed text from scanned documents.

Question 18

Printers connected to the Internet that provide printing services to others on the Internet are called ________.

Accepted Answer

Cloud printers are printers that are connected to the internet and can provide printing services to other devices on the internet. This allows users to print from anywhere, as long as they have an internet connection.
