1. A small healthcare organization is replacing several aging desktop
computers used by administrative employees who primarily work with
electronic documents, spreadsheets, web-based applications, email, and
video-conferencing software. The organization wants the new computers
to process several applications simultaneously without significant
slowdown while also ensuring that employees can store temporary
working data efficiently. Which computer component has the greatest
direct effect on the system's ability to hold and quickly access the
programs and data that are actively being used?
A. Solid-state drive
B. Random access memory (RAM)
C. Graphics processing unit (GPU)
D. Power supply unit (PSU)
Answer: B. Random access memory (RAM)
2. A university student is purchasing a computer for coursework that
involves word processing, spreadsheets, internet research, presentations,
programming assignments, and frequent multitasking between several
applications. The student does not intend to perform professional video
editing or advanced 3D rendering but wants the computer to remain
responsive when many browser tabs and applications are open
simultaneously. Which upgrade would most directly improve the
computer's ability to manage multiple active applications?
A. Increasing RAM capacity
B. Increasing monitor resolution
,2
C. Replacing the keyboard
D. Increasing printer memory
Answer: A. Increasing RAM capacity
3. An organization needs to replace traditional magnetic hard disk drives
in employee laptops because the computers take too long to start
applications and boot the operating system. The organization wants a
storage technology that has no moving mechanical components and
generally provides substantially faster access to stored information.
Which technology best meets these requirements?
A. Optical disc
B. Magnetic tape
C. Solid-state drive
D. Floppy disk
Answer: C. Solid-state drive
4. A computer technician is troubleshooting a workstation that suddenly
shuts down whenever the employee attempts to run computationally
demanding software. The technician determines that the processor,
RAM, and storage devices are functioning normally but discovers that
the computer is not receiving sufficient electrical power under heavy
load. Which hardware component should the technician investigate most
closely?
A. Network interface card
B. Power supply unit
C. Sound card
D. Optical drive
Answer: B. Power supply unit
,3
5. A company purchases computers with processors that contain
multiple processing cores. Employees frequently run a web browser,
spreadsheet application, communication software, and other programs
simultaneously, and the organization wants the processor to handle
multiple computational tasks efficiently. What is the primary advantage
associated with having multiple CPU cores?
A. Increased physical storage capacity
B. Ability to process multiple instruction streams more efficiently
C. Elimination of the need for RAM
D. Automatic conversion of analog signals to digital signals
Answer: B. Ability to process multiple instruction streams more
efficiently
6. A user is comparing two computer displays for office work and
notices that one display has a resolution of 1920 × 1080 while another
has a resolution of 3840 × 2160. Assuming the screens are otherwise
comparable, what does the higher resolution primarily indicate?
A. The display contains more pixels
B. The computer contains more RAM
C. The processor operates at a higher clock speed
D. The display consumes less electricity
Answer: A. The display contains more pixels
7. A company is purchasing laptops for employees who frequently travel
between offices and need to connect to wireless networks, Bluetooth
peripherals, cloud applications, and corporate resources. The IT
department wants employees to have convenient wireless connectivity
, 4
without requiring physical network cables for routine internet access.
Which technology provides the primary wireless local-area network
connectivity needed for this purpose?
A. Wi-Fi
B. HDMI
C. SATA
D. USB
Answer: A. Wi-Fi
8. A graphic designer is working with high-resolution images, animation
software, and three-dimensional models that require substantial parallel
processing for graphical calculations. The organization wants to upgrade
a component specifically designed to accelerate graphics rendering and
visual computations. Which component would be the most appropriate
choice?
A. GPU
B. PSU
C. NIC
D. HDD
Answer: A. GPU
9. A company wants to ensure that employees can connect external
storage devices, keyboards, mice, cameras, and other peripherals to their
computers through a widely supported interface. The organization also
wants the interface to support data transfer and, depending on the
implementation, power delivery. Which interface is most appropriate?
A. USB
B. VGA
