QUESTION 1
What is the primary function of the motherboard in a computer?
A) To store data permanently on the hard drive
B) To connect all computer components together and enable communication
between them
C) To provide cooling for internal components
D) To convert AC power to DC power for the system
E) To manage user input through peripherals only
✓ CORRECT ANSWER: B
EXPERT RATIONALE: The motherboard is the central circuit board that serves as
the main hub for all computer components. It contains the bus system that enables
communication between the CPU, RAM, storage drives, and all other connected
devices. While other options describe different computer functions, only the
motherboard acts as the primary connection point for all internal components.
QUESTION 2
,Which of the following best describes the function of RAM (Random Access
Memory)?
A) Permanent data storage on the computer
B) Temporary memory used to store data and programs currently being executed
C) A type of read-only memory used for BIOS
D) The cache memory on the CPU
E) Secondary storage for archived files
✓ CORRECT ANSWER: B
EXPERT RATIONALE: RAM is volatile memory that provides temporary storage for
data and instructions while programs are running. When the computer is powered
off, RAM is cleared. It enables fast access to data needed by the CPU during
execution, which is why it's called "random access" memory. Options A and E
describe permanent storage, option C describes ROM, and option D describes a
different memory type.
QUESTION 3
What does the CPU (Central Processing Unit) do?
A) Stores all permanent data
B) Executes instructions and performs calculations for all programs running on the
computer
C) Manages network connectivity
D) Controls the display output only
E) Provides cooling for other components
✓ CORRECT ANSWER: B
EXPERT RATIONALE: The CPU is the core processing unit that executes instructions
from programs and performs all necessary calculations. It controls the overall
operation of the computer by fetching, decoding, and executing instructions from
,RAM. The other options describe functions of different components like storage,
network interface, graphics card, and cooling systems.
QUESTION 4
Which of the following is an example of an input device?
A) Monitor
B) Printer
C) Keyboard
D) Speaker
E) Projector
✓ CORRECT ANSWER: C
EXPERT RATIONALE: A keyboard is a classic input device that allows users to send
data and commands to the computer. Input devices are hardware that facilitate
communication from the user to the computer. Monitors, projectors, and speakers
are output devices that display or produce information, while a printer is also an
output device. Only the keyboard allows user input.
QUESTION 5
What is the primary purpose of an operating system?
A) To manufacture computer hardware
B) To manage hardware resources and provide a platform for running applications
C) To create video games only
D) To store permanent data
E) To connect to the internet exclusively
✓ CORRECT ANSWER: B
, EXPERT RATIONALE: An operating system (OS) is system software that manages
computer hardware resources including the CPU, memory, and storage. It provides
an interface for users and applications to interact with hardware and coordinates
all system operations. The OS enables other programs to run by allocating
resources appropriately. The other options describe specific functions or
misunderstand the OS role.
QUESTION 6
Which of the following is NOT a common operating system?
A) Windows
B) macOS
C) Linux
D) Android
E) Photoshop
✓ CORRECT ANSWER: E
EXPERT RATIONALE: Photoshop is application software (an image editing
program), not an operating system. Windows, macOS, Linux, and Android are all
operating systems that manage hardware and provide platforms for running
applications. Operating systems run at the core level of a computer, while
applications run on top of the OS.
QUESTION 7
What does BIOS stand for?
A) Basic Internal Operating System
B) Basic Input/Output System
C) Built-in Internet Operating Software
D) Backup Input Output Service
