Here are the answers to the questions: Question 40: What does LAN stand for in networking? a) Local Access Network b) Large Area Network c) Local Area Network d) Longitudinal Area Network The correct option is c). c) Local Area Network Que. 1: a) The primary function of the motherboard in a computer is to act as the central communication backbone, connecting all the computer's components and allowing them to communicate with each other. It also distributes power to the components. b) 4 components typically found on the motherboard: • CPU (Central Processing Unit) socket • RAM (Random Access Memory) slots • Chipset (Northbridge and Southbridge, or a single PCH) • Expansion slots (e.g., PCIe slots for graphics cards, network cards) • BIOS/UEFI chip • SATA ports (for connecting storage devices) • USB headers c) 4 examples of pointing devices: • Mouse • Trackball • Touchpad • Joystick • Stylus/Light pen • Touchscreen Que. 2: a) Application software is designed to perform specific tasks for the user, such as word processing or web browsing. System software, on the other hand, manages and controls the computer hardware and provides a platform for application software to run. Examples of application software: Microsoft Word, Google Chrome. Examples of system software: Operating System (e.g., Windows, macOS), Device Drivers. b) The function of an antivirus software is to detect, prevent, and remove malicious software (malware) like viruses, worms, and Trojans from a computer system, protecting data and system integrity. c) 2 examples of web browsers: • Google Chrome • Mozilla Firefox • Microsoft Edge • Safari Que. 3: a) Computer networking is the practice of interconnecting two or more computing devices to share data, resources, and services. b) 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) • Entertainment (e.g., streaming videos, online gaming, social media) • Education (online courses, tutorials) c) State and explain the uses of 2 network devices: • Router: A router connects multiple networks and forwards data packets between them. It determines the best path for data to travel to its destination, enabling communication between different local networks and the internet. • Switch: A switch connects multiple devices within a single local area network (LAN). It receives data from one device and forwards it only to the intended recipient device, improving network efficiency by reducing unnecessary traffic. • Hub: A hub connects multiple devices in a network and broadcasts all incoming data to all connected devices. It operates at the physical layer and is less efficient than a switch. • Modem: A modem (modulator-demodulator) converts digital signals from a computer into analog signals for transmission over telephone lines, cable, or fiber, and vice versa, allowing computers to connect to the internet. Que. 4: a) 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 (performs calculations), RAM (stores data temporarily), 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 motherboard (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) Full meaning of the following abbreviations: • ASCII: American Standard Code for Information Interchange • EBCDIC: Extended Binary Coded Decimal Interchange Code
