Understanding Computer Systems

What are the main components of a computer system?

• Network cables and routers

• Operating system and software applications

• The main components of a computer system are CPU, memory (RAM), storage, and input/output devices.

• Motherboard, power supply, and graphics card

What is the primary function of the CPU?

• The primary function of the CPU is to execute instructions and process data.

• To provide power to the computer

• To store data permanently

• To manage network connections

How does RAM affect a computer's performance?

• RAM only stores data temporarily and has no impact on performance.

• More RAM always means a faster computer regardless of other components.

• RAM affects a computer's performance by enabling faster data access and improving multitasking capabilities.

• RAM is primarily used for long-term data storage in a computer.

What is an operating system and what are its functions?

• An operating system is a type of hardware that enhances computer performance.

• An operating system is system software that manages computer hardware and software resources, providing services for computer programs.

• An operating system is a programming language used for software development.

• An operating system is a database management system that stores user data.

Name two types of hardware components in a computer.

• Hard Drive, Monitor

• Printer, Scanner

• Keyboard, Mouse

• CPU, RAM

What is the difference between hardware and software?

• Hardware is the physical part of a computer; software is the programs that run on it.

• Hardware and software are the same thing.

• Software refers to the physical components of a computer.

• Hardware is the software that runs on a computer.

What role does the motherboard play in a computer system?

• The motherboard stores all the data in a computer system.

• The motherboard acts as a cooling system for the CPU.

• The motherboard is responsible for powering the computer.

• The motherboard connects and allows communication between all components of a computer system.

How does the operating system manage memory?

• The operating system does not track memory usage and relies on user input for memory allocation.

• The operating system uses memory only for running applications without any management.

• Memory is managed by the hardware directly without any involvement from the operating system.

• The operating system manages memory by allocating, tracking, and optimizing memory usage through techniques like virtual memory, paging, and segmentation.

What is the purpose of input and output devices?

• Input devices are used for printing; output devices are used for scanning.

• Input devices capture user data; output devices display or output information.

• Input devices are for audio only; output devices are for video only.

• Input devices only store data; output devices do not process information.

Can you list examples of system software?

• Office productivity software (e.g., Microsoft Office)

• Examples of system software include operating systems (e.g., Windows, Linux), device drivers, and firmware.

• Web browsers (e.g., Chrome, Firefox)

• Antivirus programs (e.g., Norton, McAfee)
