A)IEEE 1394
B)IEEE 802.1x
C)IEEE 1399
D)IEEE 1934

Accepted Answer

IEEE 1394 is the official name of the peripheral bus commonly known as FireWire or i.Link. The other options (B, C, D) are not correct names for this peripheral bus.

Question 3

____ CRT monitors draw a screen by making two passes.
A)Multipass
B)Multipath
C)Noninterlaced
D)Interlaced

Accepted Answer

Interlaced CRT monitors draw a screen by making two passes, first drawing all the odd numbered lines, then returning to draw the even numbered lines in between. This technique was used to reduce flicker on early CRT displays.

Question 4

SuperSpeed USB is about ten times faster than Hi-Speed USB and roughly five times faster than FireWire 800.

Accepted Answer

According to the USB-IF (USB Implementers Forum), SuperSpeed USB (USB 3.0) has a maximum transfer rate of 5 Gbps, which is about ten times faster than Hi-Speed USB (USB 2.0) with a maximum transfer rate of 480 Mbps. SuperSpeed USB is also roughly five times faster than FireWire 800, which has a maximum transfer rate of 800 Mbps.

Question 5

A)IEEE 1394
B)IEEE 802.9
C)IEEE 1394a
D)IEEE 1394.2

Accepted Answer

IEEE 1394a supports speeds up to 400 Mbps and is sometimes called FireWire 400.

Question 6

To protect the data on a USB storage device while removing it,double-click the ____ icon in the notification area before removing the device.
A)Format
B)Safely Eject Hardware
C)Eject
D)Safely Remove Hardware

Accepted Answer

The "Safely Remove Hardware" option is the best choice as it ensures that all write operations to the device have been completed and that the device can be safely removed without data loss or corruption. The other options may cause data loss or corruption if the device is not properly ejected.

Question 7

IEEE 1394 uses ____ data transfer,meaning that data is transferred continuously without breaks.
A)asynchronous
B)isolated
C)symmetric
D)isochronous

Accepted Answer

IEEE 1394 uses isochronous data transfer, which means that data is transferred continuously without breaks.

Question 8

Because USB devices are hot-swappable,it's never a problem to plug or unplug a device while it is turned on.

Accepted Answer

While USB devices are designed to be hot-swappable, meaning they can be connected or disconnected without shutting down the system, there can still be issues such as data corruption or hardware damage if the device is not properly ejected or if there is a power surge.

Question 9

BIOS manages ____ lines that are used by a device to hail the CPU asking for data to be processed.
A)DMA
B)ACK
C)IRQ
D)ARQ

Accepted Answer

BIOS manages IRQ (Interrupt Request) lines that are used by a device to interrupt the CPU and ask for data to be processed. DMA (Direct Memory Access) lines are used by devices to access system memory directly, ACK (Acknowledgment) lines are used to acknowledge receipt of data or signals, and ARQ (Automatic Repeat Request) lines are not related to system interrupts or device communication.

Question 10

____ can use cables up to 100 meters (328 feet),and uses a 9-pin rectangular connector.
A)1394a
B)1394b
C)1394
D)1394c

Accepted Answer

1394b, also known as FireWire 800, supports cable lengths up to 100 meters and uses a 9-pin connector.

Question 11

Problems with a device can sometimes be solved by updating the ____ or firmware.
A)device patches
B)device drivers
C)device scanners
D)device containers

Accepted Answer

Device drivers are software programs that allow the operating system to communicate with the hardware device. Updating the device drivers can solve compatibility issues, fix bugs, and improve performance. Sometimes, device manufacturers release new firmware that contains important fixes and enhancements, which can also solve device problems. However, options A, C, and D are not correct as they do not address the issue of updating software to solve device problems.

Question 12

Ports on the motherboard can be disabled or enabled in ____ setup.
A)RAM
B)firmware
C)Northbridge
D)BIOS

Accepted Answer

The BIOS (Basic Input/Output System) setup is where ports on the motherboard can be disabled or enabled. The BIOS is firmware that initializes and tests hardware components when a computer is first turned on, and it provides configuration information for the operating system.

Question 13

A serial port is provided by the motherboard or might be provided by an adapter card called a(n)____ card.
A)interrupt
B)storage
C)I/O controller
D)Southbridge

Accepted Answer

An I/O controller is responsible for managing the input/output operations of a computer system and can provide an interface for a serial port. While the Southbridge may handle some I/O functions, it is not specifically designed to provide a serial port. Interrupt and storage cards also do not typically provide serial port functionality.

Question 14

A ____ device is an input device that inputs biological data about a person,which can be input data to identify a person's fingerprints,handprints,face,voice,eye,and handwritten signature.
A)biometric
B)biomechanical
C)simulated biology
D)biostatic

Accepted Answer

A biometric device is specifically designed for inputting biological data about a person in order to identify them based on unique physical characteristics such as fingerprints, handprints, face, voice, eye, and handwritten signature. Biomechanical devices focus on measuring movement and position, while simulated biology devices may simulate biological processes but do not collect data about an individual's unique biological characteristics. Biostatic is not a commonly used term in the context of input devices.

Question 15

Newer computers do not allow you to boot without a keyboard.

Accepted Answer

This statement is false. Newer computers allow you to boot without a keyboard.

Question 16

____ systems and peripherals have the U.S.Green Star,indicating that they satisfy certain energy-conserving standards of the U.S.Environmental Protection Agency (EPA).
A)Energy Star
B)Energy Saving
C)Energy Wise
D)Green Energy

Accepted Answer

The U.S. Green Star certification is awarded to systems and peripherals that meet energy-conserving standards set by the U.S. Environmental Protection Agency (EPA). This certification is called Energy Star.

Question 17

An I/O device can be only be internal.

Accepted Answer

An I/O device can be both internal (e.g. hard drive, optical drive) or external (e.g. keyboard, mouse, printer, scanner).

Question 18

A(n)____ monitor (also called a progressive monitor)draws the entire screen in one pass.
A)multipass
B)multipath
C)noninterlaced
D)interlaced

Accepted Answer

A noninterlaced monitor, also known as a progressive monitor, draws the entire screen in one pass. This means the whole image is displayed at once, without the need for interlacing to display half the image at a time. The other options, multipass and multipath, do not refer to monitor technologies, and interlaced monitors draw half the screen at a time resulting in a flickering effect.

Question 19

Devices and their device drivers are managed using ____.
A)System Manager
B)Computer Manager
C)Device Manager
D)Control Panel

Accepted Answer

Device Manager is the tool used to manage devices and their drivers in Windows operating systems. System Manager and Computer Manager are not valid tools for managing devices and drivers. Control Panel may allow access to Device Manager, but it is not the primary tool used for this purpose.

Question 20

A ____ is an input device that uses a monitor or LCD panel as the backdrop for input options.
A)resistor
B)tablet
C)keyboard
D)touch screen

Accepted Answer

A touch screen is an input device that uses a monitor or LCD panel as the backdrop for input options. It allows users to select options and input information by touching the screen directly.
