Understanding Computer Systems and Logic

What are the main components of a computer system?

• Graphics card, motherboard, power supply, and software

• Network cables, printers, speakers, and monitors

• Operating system, antivirus software, web browser, and email client

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

Define hardware and software in the context of a computer.

• Hardware is the software that runs on a computer.

• Hardware and software are interchangeable terms for computer components.

• Software refers to the physical parts of a computer.

• Hardware is the physical components of a computer; software is the programs that run on the hardware.

List three examples of input devices.

• Printer

• Monitor

• Projector

• Keyboard, Mouse, Scanner

What is the function of an output device?

• To store data for future use.

• To process data and perform calculations.

• To connect different computer systems.

• To present data from a computer to the user.

Explain the role of the CPU in a computer system.

• The CPU executes instructions, performs calculations, and manages data flow in a computer system.

• The CPU primarily handles network connections and internet access.

• The CPU is responsible for managing the power supply of the computer.

• The CPU stores all data permanently in memory.

Differentiate between primary memory and secondary memory.

• Primary memory is non-volatile and permanent, while secondary memory is volatile and temporary.

• Primary memory is used for long-term storage, while secondary memory is used for short-term tasks.

• Primary memory is volatile and temporary, while secondary memory is non-volatile and permanent.

• Primary memory has a larger capacity than secondary memory.

What is cache memory and why is it important?

• Cache memory is used for long-term data storage.

• Cache memory decreases the speed of data access for the CPU.

• Cache memory is only relevant for graphics processing units (GPUs).

• Cache memory is important because it significantly increases the speed of data access for the CPU, leading to faster processing and improved system efficiency.

Convert 1024 bytes into kilobytes (KB).

• 512 KB

• 2 MB

• 1 KB

• 2048 bytes

What is the difference between a compiler and an interpreter?

• A compiler translates the whole program at once, while an interpreter translates it line-by-line.

• A compiler is used for scripting languages, while an interpreter is used for compiled languages.

• A compiler translates code into machine language, while an interpreter translates it into assembly language.

• A compiler executes the program while an interpreter does not.

Name two types of system software.

• Utility Program

• Application Software

• Operating System, Device Driver

• Firmware
