Essentials of Computer Science

What are the main components of computer hardware?

• CPU, RAM, storage devices, motherboard, power supply, input/output devices

• Operating system, software applications, network cables

• Monitor, keyboard, mouse pad

• Graphics card, sound card, cooling system

Define the term 'software' and its importance.

• Software is a type of hardware that stores data.

• Software is a collection of programs and data that instructs a computer on how to perform tasks, and it is essential for enabling functionality and user interaction with hardware.

• Software is irrelevant to computer functionality.

• Software is only the physical components of a computer.

What is the difference between system software and application software?

• System software is only for mobile devices.

• System software manages hardware; application software performs user-specific tasks.

• Application software is used to manage hardware resources.

• System software is designed for gaming purposes.

Explain the function of an operating system.

• The function of an operating system is to manage hardware and software resources, providing a user interface and enabling the execution of applications.

• An operating system is solely responsible for internet connectivity.

• Operating systems are only used for managing user accounts.

• The primary role of an operating system is to create hardware components.

What are the different types of data storage devices?

• Hard disk drive

• Cloud storage

• Magnetic storage, Solid-state storage, Optical storage, Flash storage

• Tape storage

Describe the purpose of RAM in a computer system.

• RAM helps in cooling the CPU during operations.

• RAM is responsible for managing network connections.

• RAM is used for long-term data storage.

• The purpose of RAM in a computer system is to provide fast, temporary storage for data and instructions that the CPU needs while performing tasks.

What is the role of a hard drive in data storage?

• The role of a hard drive in data storage is to provide persistent storage for digital information.

• A hard drive only stores temporary files during system boot.

• A hard drive is used for processing data in real-time.

• A hard drive is primarily responsible for running applications.

Explain the concept of networking in computers.

• Networking involves only wireless connections.

• Networking in computers is the practice of connecting devices to share resources and information.

• Networking is the process of installing software on computers.

• Networking is only about connecting to the internet.

What is the difference between LAN and WAN?

• WAN is used for local connections only.

• LAN is for local connections; WAN is for long-distance connections.

• LAN is a type of WAN.

• LAN and WAN are the same type of network.

Define IP address and its significance in networking.

• An IP address is a unique identifier for devices on a network, crucial for routing and communication.

• An IP address is a physical address of a device.

• An IP address is used only for local storage.

• An IP address is a type of computer virus.
