The software has the ability to manipulate text and
graphics.
7. What two functions does a UPS provide that a surge
protector does not? (Choose two.)
It protects the computer from voltage surges.
It provides backup power from an internal battery.
It protects the computer from sudden voltage spikes.
It gives the user time to phone the electrical company.
It gives the user time to safely shut down the computer if
the power fails.
It provides backup power through a generator provided by
the wall outlet.
8. Because of the potentially dangerous voltage levels,
which two devices should you not open unless you have been specifically trained
to work on them? (Choose two.)
mouse
printer
monitor
keyboard
hard drive
power supply
9. A user reports that a peripheral device that was
installed correctly last week has not been functioning since the PC was booted
today. All other PC functions are working properly. What are three things a
service technician should do to solve the problem? (Choose three.)
Use the testing functionality on the peripheral itself, if
available.
Verify that all cables are connected properly.
Disconnect all cables connected to the computer except
those connected to the peripheral.
Ensure that the peripheral is powered on.
Disconnect the peripheral and verify that the computer is
operating normally.
Reload the computer operating system.
10. Applications can be grouped into general use software
or industry specific software. What are two examples of industry specific
software? (Choose two.)
an educational tool
presentation
spreadsheet
word processing
medical practice management software
database management
11. Which computer component is considered the nerve center
of the computer system and is responsible for processing all of the data within
the machine?
RAM
CPU
video card
sound card
operating system
12. What are two advantages of purchasing a preassembled
computer? (Choose two.)
usually a lower cost
exact components may be specified
extended waiting period for assembly
adequate for performing most general applications
suited for customers with special needs
13. Which two steps should be performed when installing a
peripheral device? (Choose two.)
Download and install the most current driver.
Connect the peripheral using any cable and any available
port on the computer.
Connect the peripheral using an appropriate cable or
wireless connection.
Test the peripheral on another machine before installing it
on the one where it will be used.
Check the computer documentation to see if the peripheral
vendor is compatible with the PC vendor.
14. Which adapter enables a computer system to exchange
information with other systems on a local network?
video card
sound card
modem card
network interface card
15. How many unique values are possible using a single
binary digit?
1
2
4
8
9
16
16. What can be used to prevent electrostatic discharge
(ESD)?

carpeted floor
grounding strap
uncluttered work space
17. Which three terms describe different types of
computers? (Choose three.)
operating system
network
laptop
desktop
Windows
mainframe
18. A user plans to run multiple applications
simultaneously on a computer. Which computer component is essential to accomplish
this?
RAM
NIC
video card
sound card
storage device
19. In newer operating systems, how are system resources
assigned by default when components are installed?
manually assigned by the operating system
manually assigned by the administrator
statically assigned by the component to a preset resource
dynamically assigned between the component and the
operating system
20. Why do servers often contain duplicate or redundant
parts?
Servers require more power and thus require more
components.
Servers should be accessible at all times.
Servers can be designed as standalone towers or rack
mounted.
Servers are required by networking standards to have
duplicate parts.
21. What are two benefits of connecting a laptop computer
to a docking station? (Choose two.)
Mobility is increased.
Less power is required.
An external monitor can be used.
More wireless security options are available.
Alternate connectivity options may be available.
