Question 2

IEEE 1394 interfaces are targeted towards comparatively slow peripherals such as keyboards and mice.

Accepted Answer

IEEE 1394 (also known as FireWire) interfaces are actually targeted towards high-speed peripherals such as external hard drives and video cameras, making them suitable for applications such as video editing and real-time data transfer. They are not typically used for slow peripherals such as keyboards and mice, which can be connected via less expensive interfaces such as USB.

Question 3

You recently purchased a new digital camera and now you want to print some of the photos you have been taking. Which type of printer are you most likely to use to print your photos?
A)inkjet
B)line
C)plotter
D)dot-matrix

Accepted Answer

Inkjet printers are widely used for printing high-quality photos as they can produce sharp and vivid images with a wide range of colors. They use liquid ink that is sprayed onto the paper in small droplets to create the image, which results in a better resolution and color accuracy than other printer types.

Question 4

A user complains that his new mouse doesn't work right. He has an old system at home and when he has had this problem, he cleaned the ball on the underside of the mouse to fix it, but this mouse doesn't have a ball on the underside. What can you tell him about his mouse?
A)the ball must have fallen out
B)the ball is hidden under an access panel on new mice
C)the mouse is an optical mouse
D)the mouse uses sonar to detect movement

Accepted Answer

The fact that the mouse doesn't have a ball on the underside indicates that it is likely an optical mouse, which uses a laser or LED to detect movement instead of a rolling ball.

Which of the following is a good practice when you are installing a new device?
A)reinitialize the kernel
B)check for a new driver
C)recompile the installed driver
D)always use the driver supplied by the OS

Accepted Answer

Checking for a new driver ensures that the device is using the most up-to-date and compatible software for optimal performance. Reinitializing the kernel and recompiling the installed driver are unnecessary steps for basic device installation. It is not always necessary to use the driver supplied by the OS, as sometimes there are better options available from the manufacturer or through updates.

Question 12

Which of the following is a common format for distributing driver files?
A)zip
B)txt
C)drv
D)ini

Accepted Answer

ZIP is a common format for distributing driver files as it allows for easy compression and organization of multiple files into one package. TXT is a text file format and is not typically used for distributing driver files. DRV is a file extension for driver files but is not a distribution format. INI is a configuration file format and is not typically used for distributing driver files.

Question 13

The office manager of your company has instructed you to find a solution for a problem. A new employee is being hired and her desk will be located where there is a table that is occupied by an older model fax machine and scanner. There is no room to put the table anywhere else and the table that holds the inkjet printer is too small for the other two devices. There is money in the budget if funds are necessary. What do you recommend?
A)put the fax and scanner on the floor and tell the new employee to step around them
B)buy a new plotter that performs scanning and faxing functions
C)replace the inkjet printer with a multifunction printer
D)each day, put the fax and scanner on the desk of an absent employee

Accepted Answer

Replacing the inkjet printer with a multifunction printer is the most practical solution as it solves the problem of lack of space and also provides all necessary functions in one device. Investing in a new plotter or putting the fax and scanner on the floor can be expensive and inconvenient, while moving the devices to an absent employee's desk would not provide a permanent solution.

Question 14

Which of the following is NOT a typical step in the process for installing new hardware on a Mac OS X system?
A)shut down the system
B)attach new hardware
C)configure dip switches
D)insert DVD/CD-ROM

Accepted Answer

Configuring dip switches is not a typical step in the process for installing new hardware on a Mac OS X system. Dip switches are more commonly found on older hardware and are used to configure settings such as IRQ and DMA channels. Mac OS X systems are more likely to automatically detect and configure new hardware without the need for manual dip switch configuration. The other three steps listed (shutting down the system, attaching new hardware, and inserting a DVD/CD-ROM) are all common steps in the hardware installation process for a Mac OS X system.

Question 15

You manage several hundred Windows 10 computers for your company. In the past, your support staff has spent a lot of time troubleshooting issues related to incompatible or faulty device drivers. You want to reduce the amount of troubleshooting your staff is doing. What is one step you can take that will help?
A)configure driver signing to disallow unsigned drivers
B)change all desktop computers to a Windows server OS
C)configure Windows Update to always download the latest drivers
D)disallow the use of hardware devices on the company computers

Accepted Answer

By configuring driver signing to disallow unsigned drivers, you ensure that only drivers that are digitally signed by a trusted publisher are installed on company computers. This can greatly reduce the risk of installing incompatible or faulty drivers, which leads to fewer troubleshooting issues for support staff.

Question 16

Device drivers perform the actual communication between physical devices and the operating system.

Accepted Answer

Device drivers are software programs that act as intermediaries between the hardware devices and the operating system, allowing the operating system to communicate with the hardware. Therefore, device drivers perform the actual communication between physical devices and the operating system.

Question 17

A user calls the help line and ask for some help installing a new keyboard. He isn't sure how to plug the keyboard into the computer because it doesn't have a cable connected to it. What advice are you likely to give him?
A)unscrew the cover from the keyboard, pull out the cable, and put the cover back on
B)connect a patch cable from the computer to the keyboard
C)return the keyboard; it must be faulty
D)plug the USB receiver into a USB port on the computer

Accepted Answer

The keyboard without a cable is likely a wireless keyboard that uses a USB receiver to connect to the computer. The user should plug the USB receiver into a USB port on the computer to establish the connection between the keyboard and the computer. Option A would not be feasible as most keyboards are not designed to be unscrewed by users. Option B is also incorrect as a patch cable is not needed for a wireless keyboard. Option C is not necessary as the keyboard is not faulty, it just needs to be properly connected using the USB receiver.

Question 18

Mouse and keyboard drivers are standard and are usually included with the OS.

Accepted Answer

Mouse and keyboard drivers are typically included with the operating system, so users do not typically need to download or install additional drivers for these peripherals.

Question 19

The management software for your sound card has just downloaded and installed the latest driver for your sound card. After a reboot your computer shows signs of instability and the sound skips. What feature should you use to resolve the problem that will cause the least disruption?
A)Windows update
B)Plug and Play
C)driver roll back
D)system restore

Accepted Answer

Driver roll back is the best choice as it allows you to revert to the previous working driver without affecting any other system settings or configurations. Windows update, Plug and Play, and system restore are more disruptive as they can potentially affect other system components and configurations.

Question 20

You have a hardcopy of a report that you found some errors on that must be corrected. The report is three pages long and you have about 20 minutes before a meeting you must attend to present the report. Unfortunately, the report was created on your laptop at home and you have no way of getting to it quickly. What is your best option?
A)retype the report on your work computer
B)scan the report and use OCR; fix the errors and re-print the report
C)use white out and a typewriter to fix the errors
D)cross out the errors with a pen and hand write the corrections

Accepted Answer

Scanning the report and using OCR (optical character recognition) technology can quickly convert the hardcopy into a digital version that can be edited on a computer. Fix the errors and re-print the report in time for the meeting. This option saves time compared to retyping the entire report, and it produces a more professional-looking document than Option C or D.
