Question 7

____ is the most widely used language for communication between computers and printers.
A) Linux
B) PostScript
C) PCL
D) USB

Accepted Answer

PCL (Printer Control Language) is a language developed by Hewlett-Packard for communication between computers and printers. It is the most widely used language for this purpose, with support from many printer manufacturers. While Linux, PostScript, and USB are all important in the world of computing and printing, none of them are specifically designed for communication between computers and printers in the same way that PCL is.

Accepted Answer

Dot pitch is the distance between pixels, which are the smallest units of an image. Picas, points, and icons are not related to dot pitch.

Question 10

In the accompanying figure, the item marked A is a(n) ____.
A) USB port
B) mouse port
C) printer port
D) modem port

Accepted Answer

The item marked A in the figure is a USB port. The rectangular shape with a symbol indicating a trident shape is a common representation of a USB port. Mouse ports and printer ports are usually round, while modem ports vary in shape but typically have a phone symbol or an Ethernet symbol next to them.

Question 11

A ____ is a sudden increase or spike in electrical energy, affecting the current that flows to electrical outlets.
A) brownout
B) UPS
C) power surge
D) battery blast

Accepted Answer

A power surge is a sudden increase in electrical energy that can overload and damage electrical devices. Brownouts refer to a drop in electrical voltage, UPS (Uninterruptible Power Supply) is a device that provides backup power in case of an outage, and battery blast is not a term commonly used in the context of electrical energy.

Question 12

The number of colors a monitor can display is referred to as ____.
A) resolution
B) color depth
C) veracity
D) GPU

Accepted Answer

Color depth refers to the number of colors that a monitor can display. It is usually measured in bits and determines the total number of colors that can be displayed. A higher color depth means that more colors can be displayed, resulting in better image quality. Resolution refers to the number of pixels on the screen, and GPU is the graphics processing unit that drives the display. Veracity refers to the truthfulness or accuracy of information, and is not related to monitor display capabilities.

Question 13

In the accompanying figure, the item marked C is a(n) ____.
A) USB port
B) serial port
C) parallel port
D) keyboard port

Accepted Answer

The item marked C is a parallel port, which is used for transmitting multiple bits of data simultaneously. USB ports and keyboard ports look different, while serial ports typically have fewer pins than parallel ports.

Question 14

It takes 800 pounds of force to remove a ____ plate, which contains a unique ID number, a warning message, and an 800 number to report a stolen computer.
A) power
B) STOP
C) StealthSignal
D) Computrace

Accepted Answer

The answer is B, STOP plate. "STOP" plates are visible deterrents that are placed on devices to thwart potential thieves. They contain a warning message, a unique ID number, and an 800 number to report a stolen computer. They are designed to be difficult to remove, requiring about 800 pounds of force, to make it harder for thieves to steal and resell the device.

Question 15

The ____ is a security mechanism that is factory-installed on many personal computers.
A) STOP plate
B) EPA
C) Kensington Security Slot
D) slate tablet

Accepted Answer

The Kensington Security Slot is a common security mechanism found on many personal computers. It allows a user to lock their device to a stationary object using a cable and lock. The other options (STOP plate, EPA, slate tablet) are not related to computer security mechanisms.
