Understanding Computer Systems

What are the four basic functions of a computer system?

• Input, Output, Analysis, Transmission

• Input, Processing, Output, Storage

• Input, Processing, Communication, Retrieval

• Input, Output, Networking, Display

Name three examples of input devices.

• Printer

• Keyboard, Mouse, Scanner

• Speaker

• Monitor

What is the role of the CPU in a computer system?

• The CPU processes instructions and manages data flow in a computer system.

• The CPU connects all peripheral devices to the computer.

• The CPU stores data permanently in memory.

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

List two output devices used to present processed data.

• Monitor, Printer

• Webcam

• Scanner

• Speaker

What is the purpose of storage devices in a computer system?

• To manage network connections in a computer system.

• The purpose of storage devices is to store data and programs in a computer system.

• To increase the processing speed of the CPU.

• To provide power to the computer components.

How does a scanner function as an input device?

• A scanner captures images or text from physical documents and converts them into digital data.

• A scanner only works with digital files.

• A scanner prints documents directly onto paper.

• A scanner is used to play audio recordings.

What type of output device is a printer classified as?

• Storage device

• Network device

• Input device

• Output device

Explain the difference between input and output devices.

• Input devices display information, while output devices capture data.

• Input devices are used for storage, while output devices are for processing.

• Input devices allow data entry, while output devices present data.

• Input devices are only for audio, while output devices are only for video.

Give an example of a processing task performed by a computer.

• Displaying images on a screen.

• Performing arithmetic calculations in a calculator application.

• Storing data in a database management system.

• Transmitting data over a network connection.

Why is it important to have storage devices in a computer system?

• Storage devices are unnecessary for modern computers.

• Storage devices are primarily for enhancing graphics performance.

• Storage devices are important for saving and retrieving data in a computer system.

• Storage devices are only used for running applications.
