Exploring Computer Systems

What is the main function of a computer's hardware?

• The main function of a computer's hardware is to execute instructions and process data.

• To provide user interface design

• To connect to the internet

• To store data permanently

Define software in the context of computer systems.

• Software is the physical hardware of a computer system.

• Software refers to the electrical components of a computer.

• Software is a type of computer virus that disrupts operations.

• Software is a set of instructions and data that enables a computer to perform specific tasks.

What are the primary components of computer hardware?

• Monitor, keyboard, mouse pad

• Operating system, software applications, network cables

• Graphics card, sound card, cooling system

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

Explain the difference between input and output devices.

• Input devices send data to a computer; output devices present data from a computer.

• Input devices are only keyboards; output devices are only monitors.

• Input devices display information; output devices receive data.

• Input devices are used for storage; output devices are for processing.

Give two examples of input devices.

• Projector

• Scanner

• Keyboard, Mouse

• Printer

What is an output device? Provide an example.

• Printer

• Speaker

• Monitor

• Projector

What role does storage play in a computer system?

• Storage has no impact on system performance.

• Storage is only used for temporary files.

• Storage is crucial for data retention and program accessibility in a computer system.

• Storage is primarily for hardware maintenance.

Name three types of storage devices.

• floppy disk

• CD-ROM

• magnetic tape

• hard disk drive, solid-state drive, USB flash drive

What is RAM and why is it important?

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

• RAM is a type of permanent memory that stores data indefinitely.

• RAM is a type of hardware that enhances internet speed.

• RAM is a type of volatile memory that temporarily stores data for quick access, and it is important for system performance and multitasking.

Describe the function of a CPU in a computer.

• The CPU functions as the brain of the computer, executing instructions and processing data.

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

• The CPU primarily handles network connections and internet access.

• The CPU stores all the data permanently.
