LSUS MHA 705 – PPs Module 2 Exam Questions and
Answers| Updated| Pass Guaranteed
1. A computer system is best defined as:
A. Only the physical box and monitor
B. An integrated combination of hardware, software, data, procedures,
and people that accepts input, processes it, and produces output
C. Only the programs installed on a device
D. Only the internet connection
Answer: B. An integrated combination of hardware, software, data,
procedures, and people that accepts input, processes it, and
produces output
Rationale: A computer system includes more than the machine itself.
Hardware, software, data, procedures, and users work together to
accomplish tasks.
2. Which of the following is an example of computer hardware?
A. Keyboard
B. Operating system
C. Word processor
D. Database management system
Answer: A. Keyboard
Rationale: Hardware refers to the physical components of a computer.
Operating systems, word processors, and database systems are software.

,3. The central processing unit (CPU) is responsible for:
A. Permanently storing all files
B. Displaying output to users
C. Connecting to the internet only
D. Executing instructions and performing calculations and logical
operations
Answer: D. Executing instructions and performing calculations and
logical operations
Rationale: The CPU is the 'brain' of the computer. It fetches, decodes, and
executes instructions, and includes the control unit and arithmetic logic unit
(ALU).
4. Which components make up the CPU's core functions?
A. Keyboard and mouse
B. Monitor and printer
C. Arithmetic logic unit (ALU) and control unit
D. Hard drive and flash drive
Answer: C. Arithmetic logic unit (ALU) and control unit
Rationale: The ALU performs arithmetic and logical operations, while the
control unit directs the flow of instructions and data within the computer.
5. Random access memory (RAM) is best described as:
A. Permanent storage that retains data when power is off
B. Volatile, temporary memory that holds data and programs currently
in use
C. A type of input device
D. A network protocol
Answer: B. Volatile, temporary memory that holds data and programs
currently in use
Rationale: RAM is fast working memory. Its contents are lost when the
computer is powered off, so work must be saved to storage.

, 6. Read-only memory (ROM) differs from RAM in that ROM:
A. Is non-volatile and typically holds permanent startup instructions
such as firmware
B. Is erased when power is off
C. Is used only for graphics
D. Is always larger than RAM
Answer: A. Is non-volatile and typically holds permanent startup
instructions such as firmware
Rationale: ROM retains its contents without power and typically contains
boot instructions that start the computer.
7. Which statement correctly compares a hard disk drive (HDD) and a
solid-state drive (SSD)?
A. An HDD is always faster than an SSD
B. An SSD uses spinning platters
C. They are both volatile memory
D. An SSD has no moving parts and is generally faster, while an HDD
uses spinning platters and is typically cheaper per unit of storage
Answer: D. An SSD has no moving parts and is generally faster, while
an HDD uses spinning platters and is typically cheaper per unit of
storage
Rationale: SSDs use flash memory and provide faster access, durability,
and lower power use. HDDs are mechanical and often provide larger
capacity at lower cost.
8. Which of the following is an INPUT device?
A. Printer
B. Monitor
C. Scanner
D. Speaker
Answer: C. Scanner
Rationale: Input devices, such as keyboards, mice, scanners, barcode
readers, and microphones, send data into the computer. Output devices
present results.
