Examination Bank with correct
answers and rationales
Module 1: Hardware, Software, and Data
Infrastructure
Which component functions as a computer's working memory, providing
temporary storage for data and instructions currently in use by the central
processing unit?[1]
A. Central processing unit (CPU)
B. Read-only memory (ROM)
C. Random access memory (RAM)
D. Solid state drive (SSD)
Rationale: RAM volatilely stores active data and application instructions for
immediate processing by the CPU.
What type of secondary storage medium utilizes magnetic recording tracks
on plastic ribbons to archive sequential data backups cost-effectively?[1]
A. Read-only memory
B. Cache
C. Magnetic tape
D. Random access memory
Rationale: Magnetic tape is standard for long-term, high-capacity sequential
data archiving and disaster recovery backups.
,Which specific data set consumes disk space that is directly proportional to
the incremental change in the data since it was last captured?[1]
A. Static
B. Snapshot
C. Dynamic
D. Big
Rationale: A snapshot captures the state of a data system at a specific
point, occupying space only as modified blocks accumulate.
Which multiuser operating system originally developed at AT&T's Bell
Laboratories serves as the foundational architecture for many modern
enterprise Unix-like systems?[1]
A. OS X
B. Android
C. Unix
D. Linux
Rationale: Unix was developed at Bell Labs in the late 1960s and early
1970s, establishing multi-user multitasking paradigms.
Which software classification calculates revenue, pipeline progression, and
interactions segmented by client geography?[1]
A. Personnel management
B. Inventory management
C. Customer relationship management (CRM)
D. Human resources management (HRM)
Rationale: CRM applications track client interactions, sales pipelines, and
regional distribution metrics.
Which tool enables corporate employees to communicate internally in real-
time text streams across organizational networks?[1]
A. Word processor
B. Instant messaging
, C. Spreadsheet
D. Email
Rationale: Instant messaging applications offer instantaneous synchronous
text-based communication channels.
Which category of software is specifically designed to manage organizational
personnel records, payroll, and benefits administration?[1]
A. Human resources management (HRM)
B. Customer relationship management
C. Supply chain management
D. Enterprise resource planning
Rationale: HRM systems automate employee data handling, payroll
administration, and benefits tracking.
What is the primary characteristic that distinguishes an SSD from a
traditional Hard Disk Drive (HDD)?[1]
A. Mechanical platter rotation
B. Flash memory storage without moving parts
C. Higher magnetic interference vulnerability
D. Slower sequential read speeds
Rationale: SSDs use solid-state flash memory chips, eliminating mechanical
read/write heads and improving speed and durability.
What term describes high-speed volatile memory integrated directly into or
close to the CPU core to accelerate data retrieval?[1]
A. Cache memory
B. Virtual memory
C. CMOS memory
D. Flash memory
Rationale: Cache memory stores frequently used instructions close to the
processor execution units.
