Question 01
Which hardware component performs most of the calculations for a computer?
a) Hard drive
b) Random Access Memory (RAM)
c) Central Processing Unit (CPU)
d) Network Interface Card (NIC)
Correct Answer: c) Central Processing Unit (CPU)
Explanation: The CPU, often referred to as the "brain" of the computer, is responsible for executing instructions and performing calculations. The hard drive stores data, RAM temporarily holds data for quick access, and the NIC manages network communications. The CPU processes most of the tasks required by software.
Question 02
In which topology does each network node connect to two other nodes forming a closed loop?
a) Star
b) Bus
c) Ring
d) Mesh
Correct Answer: c) Ring
Explanation: In a ring topology, each computer is connected to two other computers, forming a ring. The network sends data in one direction around the ring. Star topology connects each node to a central hub, while bus uses a single backbone.
Question 03
Which type of software enables a user to compose, edit, and print documents?
a) Database Management System (DBMS)
b) Word Processor
c) Operating System
d) Presentation Software
Correct Answer: b) Word Processor
Explanation: Word processing software, like Microsoft Word, allows users to create and edit documents. DBMS manages databases, operating systems run the computer, and presentation software is for creating slideshows.
Question 04
Which of the following is an advantage of the client-server network architecture?
a) All clients must have the same IP address
b) Centralized management of resources
c) Easier file sharing without security concerns
d) Each device acts as both a server and a client
Correct Answer: b) Centralized management of resources
Explanation: In a client-server network, resources are managed centrally from the server, which simplifies management and increases control. The statement that all clients need the same IP address is false and would cause conflicts in communication.
Question 05
What is the most common function of Random Access Memory (RAM)?
a) Storing the operating system permanently
b) Holding data temporarily for quick access by the CPU
c) Acting as permanent storage for programs
d) Managing network protocols
Correct Answer: b) Holding data temporarily for quick access by the CPU
Explanation: RAM temporarily stores data that the CPU needs to access quickly. Unlike a hard drive, it is not used for permanent storage.
Question 06
What does Moore’s Law predict about the advancement of computing power?
a) Computing power decreases by 18 months
b) Computing power triples every 10 years
c) Computing power doubles every 18 months
d) Computing power remains static over time
Correct Answer: c) Computing power doubles every 18 months
Explanation: Moore's Law predicts that the number of transistors on a microchip will double approximately every 18 months, leading to a proportional increase in processing power.
Question 07
Which of the following is NOT a peripheral device?
a) Printer
b) Web camera
c) Central Processing Unit (CPU)
d) External Hard Drive
Correct Answer: c) Central Processing Unit (CPU)
Explanation: Peripheral devices are external devices connected to the computer, such as printers and external hard drives. The CPU is an internal component that performs calculations.
Question 08
Which protocol is responsible for defining how messages are formatted and transmitted on the internet?
a) HTML
b) HTTP
c) TCP/IP
d) FTP
Correct Answer: b) HTTP
Explanation: HTTP (Hypertext Transfer Protocol) defines the rules for transmitting web pages over the internet. TCP/IP governs the overall communication protocols for networking.
Question 09
What is the defining characteristic of system software?
a) It performs a specific task for the user
b) It manages hardware and software on a computer
c) It helps users create and edit presentations
d) It provides tools for designing web pages
Correct Answer: b) It manages hardware and software on a computer
Explanation: System software, like operating systems, manages the hardware and software, ensuring everything functions properly.
Question 10
Which network topology connects each node directly to a central hub?
a) Mesh
b) Star
c) Bus
d) Ring
Correct Answer: b) Star
Explanation: In a star topology, each node connects directly to a central hub. This makes the hub a central point for all communications.
Question 11
Which type of computer is the least powerful in terms of processing capabilities?
a) Midrange computer
b) Microcomputer
c) Mainframe computer
d) Supercomputer
Correct Answer: b) Microcomputer
Explanation: Microcomputers, such as desktops and laptops, are the least powerful in terms of processing compared to midrange computers, mainframes, and supercomputers, which handle more complex processing tasks.
Question 12
Which storage device uses integrated circuits and flash memory to store data persistently?
a) Optical disk
b) Solid State Drive (SSD)
c) Hard Disk Drive (HDD)
d) RAM
Correct Answer: b) Solid State Drive (SSD)
Explanation: SSDs use flash memory to store data persistently, providing faster access and more durability compared to traditional mechanical hard drives (HDDs).
Question 13
Which of the following is a computer network that covers a large geographical area and connects LANs, CANs, and MANs together?
a) Local Area Network (LAN)
b) Wide Area Network (WAN)
c) Campus Area Network (CAN)
d) Metropolitan Area Network (MAN)
Correct Answer: b) Wide Area Network (WAN)
Explanation: A WAN connects multiple local networks (LANs) across large geographical areas, such as cities or even countries, making it suitable for large organizations.
Question 14
Which component allows network devices to communicate by forwarding data to the correct location?
a) Router
b) Firewall
c) Switch
d) Hub
Correct Answer: c) Switch
Explanation: A switch filters and forwards data to the appropriate destination within a local network, unlike a hub, which sends the data to all devices on the network.
Question 15
Which of the following defines a file system that stores data in tables connected by relationships?
a) Flat-file database
b) Network database
c) Relational database
d) Hierarchical database
Correct Answer: c) Relational database
Explanation: Relational databases organize data into tables that are connected via relationships. This allows for efficient querying and data management.
Question 16
What is the purpose of a firewall in network security?
a) To speed up network traffic
b) To prevent unauthorized access to a network
c) To establish virtual private networks (VPNs)
d) To allocate network bandwidth
Correct Answer: b) To prevent unauthorized access to a network
Explanation: Firewalls are designed to block unauthorized access to or from a network, thus protecting the internal systems from external threats.
Question 17
Which memory component provides temporary storage that allows data to be accessed in any order without physical movement of media?
a) Cache memory
b) Solid State Drive (SSD)
c) Random Access Memory (RAM)
d) Registers
Correct Answer: c) Random Access Memory (RAM)
Explanation: RAM provides temporary storage that can be accessed randomly without physical movement, making it suitable for fast data access.
Question 18
Which of the following network topologies creates a physical layout in the shape of a star?
a) Ring topology

d) Mesh topology
Correct Answer: c) Star topology
Explanation: In a star topology, each network device is connected to a central hub, forming a shape similar to a star.
Question 19
Which of the following is responsible for managing the operations of the CPU and all other hardware components?
a) Application software
b) Network software
c) Operating System (OS)
d) Database software
Correct Answer: c) Operating System (OS)
