Question 1: A company is upgrading its IT infrastructure and needs a processor for
office and analytics workloads. Which hardware component executes instructions
and processes data?
A) Random Access Memory (RAM)
B) Central Processing Unit (CPU)
C) Solid State Drive (SSD)
D) Power Supply Unit (PSU)
Correct Answer: B) Central Processing Unit (CPU)
The CPU is the primary component responsible for executing instructions, acting as
the brain of the computer. RAM provides temporary working memory, SSDs provide
persistent storage, and the PSU supplies power. The CPU's clock speed and core
count determine processing capability.
Question 2: An IT manager needs fast read/write storage for a database server.
Which storage uses flash memory for faster access than HDDs?
A) Magnetic tape
B) Hard Disk Drive (HDD)
C) Solid State Drive (SSD)
D) Optical disc
Correct Answer: C) Solid State Drive (SSD)
SSDs use NAND flash memory providing significantly faster read/write speeds, lower
latency, and better reliability than HDDs because they have no moving parts.
Magnetic tape is for archival storage, and optical discs are for media distribution.
Question 3: A business analyst explains system software vs. application software to
stakeholders. Which is the BEST example of system software?
A) Microsoft Excel
B) Adobe Photoshop

C) Operating System (OS)
D) CRM application
Correct Answer: C) Operating System (OS)
System software manages hardware and provides a platform for applications. The
OS is the most fundamental system software, managing memory, processes, and
hardware. Excel, Photoshop, and CRM are application software designed for specific
user tasks.
Question 4: A company needs its OS to manage multiple processes simultaneously.
Which OS function manages CPU time allocation among processes?
A) Memory management
B) Process scheduling
C) File system management
D) Device driver management
Correct Answer: B) Process scheduling
Process scheduling determines which process gets CPU access and for how long.
Memory management controls RAM, file system management organizes storage,
and device driver management enables hardware communication. Scheduling is
critical for multitasking efficiency.
Question 5: An IT technician installs a new peripheral. Which software component
acts as intermediary between the OS and a hardware device?
A) Application programming interface (API)
B) Firmware
C) Device driver
D) Utility software
Correct Answer: C) Device driver
A device driver allows the OS to communicate with hardware devices. APIs enable
software-to-software communication, firmware is embedded on hardware, and

utilities perform maintenance tasks. Without proper drivers, hardware cannot
function.
Question 6: Which BEST describes the primary function of the motherboard in a
computer system?
A) It provides temporary data storage for running programs
B) It is the main circuit board connecting and enabling communication between all
components
C) It converts AC to DC for component power needs
D) It manages network traffic and packet routing
Correct Answer: B) It is the main circuit board connecting and enabling
communication between all components
The motherboard is the main PCB housing the CPU, RAM, and connectors, serving
as the central communication backbone for all hardware components. RAM provides
temporary storage, the PSU converts power, and network cards manage traffic.
Question 7: Which is a key advantage of Linux as a server OS compared to
Windows Server?
A) Linux requires mandatory license fees
B) Linux is open-source with flexibility, no licensing costs, and strong community
support
C) Linux has limited networking protocol support
D) Linux cannot be customized for specific roles
Correct Answer: B) Linux is open-source with flexibility, no licensing costs,
and strong community support
Linux is open-source with zero licensing costs, source code access, strong
community support, and proven stability in enterprise environments. Windows Server
requires licensing and is less customizable at the kernel level.
