UPDATE ALREADY GRADED A+ ASSURED PASS
QUESTION 1 Which component of the CPU is responsible for
performing mathematical calculations and logical operations?
• A. Control Unit
• B. Arithmetic Logic Unit (ALU)
• C. Register
• D. Cache
• Correct Answer: B. Arithmetic Logic Unit (ALU)
• Detailed Rationale: The ALU is the part of the processor that
handles all arithmetic (addition, subtraction) and logical (AND, OR,
NOT) operations.
QUESTION 2 Which type of memory is volatile and loses its contents
when the power is turned off?
• A. ROM
• B. Hard Drive
• C. RAM
• D. Flash Drive
• Correct Answer: C. RAM
, • Detailed Rationale: RAM (Random Access Memory) is volatile,
meaning it requires power to maintain the stored information.
ROM, HDDs, and Flash memory are non-volatile.
QUESTION 3 What is the primary function of an Operating System (OS)?
• A. To perform complex mathematical calculations for the user
• B. To manage computer hardware and software resources
• C. To write application code for developers
• D. To provide a physical connection to the internet
• Correct Answer: B. To manage computer hardware and software
resources
• Detailed Rationale: An OS acts as an intermediary between the
user/applications and the hardware, managing memory,
processors, and devices.
QUESTION 4 Which type of software is designed to perform specific
tasks for the user, such as word processing or spreadsheets?
• A. System Software
• B. Utility Software
• C. Application Software
• D. Firmware
• Correct Answer: C. Application Software
• Detailed Rationale: Application software is end-user software
used to accomplish specific tasks, whereas system software (like
the OS) supports the computer's operation.
,QUESTION 5 In the OSI model, which layer is responsible for logical
addressing and routing?
• A. Data Link Layer
• B. Network Layer
• C. Transport Layer
• D. Physical Layer
• Correct Answer: B. Network Layer
• Detailed Rationale: The Network Layer (Layer 3) handles packet
forwarding, including logical addressing (IP addresses) and
routing.
QUESTION 6 What does a firewall primarily do?
• A. Automatically updates the operating system
• B. Monitors and controls incoming and outgoing network traffic
based on security rules
• C. Increases the internet connection speed
• D. Backs up user files to the cloud
• Correct Answer: B. Monitors and controls incoming and outgoing
network traffic based on security rules
• Detailed Rationale: Firewalls act as a security barrier, blocking or
allowing traffic based on predefined security criteria to prevent
unauthorized access.
QUESTION 7 Which cloud computing model provides virtualized
computing resources over the internet, such as servers and storage?
, • A. Software as a Service (SaaS)
• B. Platform as a Service (PaaS)
• C. Infrastructure as a Service (IaaS)
• D. Desktop as a Service (DaaS)
• Correct Answer: C. Infrastructure as a Service (IaaS)
• Detailed Rationale: IaaS provides the fundamental building
blocks—servers, storage, and networking—allowing the user to
manage the OS and applications.
QUESTION 8 What is the main difference between a LAN and a WAN?
• A. LANs use fiber optics, while WANs use copper wire
• B. LANs cover a small geographical area, while WANs cover large
geographical areas
• C. LANs are always wireless, while WANs are always wired
• D. LANs are for public use, while WANs are for private use
• Correct Answer: B. LANs cover a small geographical area, while
WANs cover large geographical areas
• Detailed Rationale: LAN (Local Area Network) covers a room or
building. WAN (Wide Area Network) connects LANs over larger
distances (cities, countries, global).
QUESTION 9 What does DHCP stand for in networking?
• A. Digital Host Connection Protocol
• B. Dynamic Host Configuration Protocol
• C. Data Hyperlink Connection Protocol
