What is the function of a router in a network?

a) To connect multiple devices within a local network

b) To store data permanently

c) To provide power to network devices

d) To perform calculations related to network traffic

The correct option is a).

a) To connect multiple devices within a local network (A router primarily connects different networks and forwards data packets between them. While option (a) is a simplified description, it is the most appropriate choice among the given options, as a router facilitates communication between devices across networks.)

SECTION B
INSTRUCTION: Attempt all questions

Que. 1:

a) What is the primary function of the motherboard in a computer?
The primary function of the motherboard in a computer is to act as the central communication backbone, connecting all the computer's components (such as the CPU, RAM, and storage devices) and allowing them to communicate with each other. It also distributes electrical power to these components.

b) List 4 components that are typically found on the motherboard.

• CPU (Central Processing Unit) socket
• RAM (Random Access Memory) slots
• Chipset (which manages data flow between components)
• Expansion slots (e.g., PCIe slots for graphics cards or other peripherals)

c) State 4 examples of pointing devices.

• Mouse
• Trackball
• Touchpad
• Joystick

Que. 2:

a) Differentiate between application software and system software, and provide 2 examples of each.
Application software is designed to perform specific tasks for the user, such as creating documents, browsing the internet, or playing games. Examples include Microsoft Word and Google Chrome.
System software, on the other hand, manages and controls the computer hardware and provides a platform for application software to run. Examples include an Operating System (e.g., Windows, macOS) and Device Drivers.

b) What is the function of an antivirus software?
The function of an antivirus software is to detect, prevent, and remove malicious software (malware) like viruses, worms, and Trojans from a computer system, thereby protecting data and maintaining system integrity.

c) State 2 examples of web browsers.

• Google Chrome
• Mozilla Firefox

Que. 3:

a) What is computer networking?
Computer networking is the practice of interconnecting two or more computing devices (such as computers, servers, or printers) to share data, resources, and services.

b) State 4 uses of the Internet.

• Communication (e.g., email, instant messaging, video calls)
• Information access (e.g., research, news, online encyclopedias)
• E-commerce (online shopping, banking, financial transactions)
• Entertainment (e.g., streaming videos, online gaming, social media)

c) State and explain the uses of 2 network devices.

• Router: A router connects multiple distinct networks (e.g., a local area network to the internet) and forwards data packets between them. It determines the most efficient path for data to travel to its destination.
• Switch: A switch connects multiple devices within a single local area network (LAN). It receives data from one device and intelligently forwards it only to the intended recipient device, improving network efficiency by reducing unnecessary traffic.

Que. 4:

a) State and explain the components of a computer system.
The components of a computer system can be broadly categorized into hardware and software.
Hardware refers to the physical, tangible parts of a computer that you can see and touch. This includes the CPU (Central Processing Unit, which performs calculations), RAM (Random Access Memory, for temporary data storage), storage devices (e.g., hard drive, SSD for permanent data storage), input devices (e.g., keyboard, mouse for user input), output devices (e.g., monitor, printer for displaying results), and the motherboard (which connects all components).
Software refers to the set of instructions, data, or programs used to operate computers and execute specific tasks. It includes system software (e.g., operating systems like Windows, macOS, which manage hardware and provide a platform for applications) and application software (e.g., word processors, web browsers, which perform specific user tasks).

b) Write the full meaning of the following abbreviations: ASCII, EBCDIC.

• ASCII: American Standard Code for Information Interchange
• EBCDIC: Extended Binary Coded Decimal Interchange Code
