Understanding Input and Output Devices

What is an input device?

• A component that displays output from a computer.

• An input device is a hardware component used to input data into a computer.

• A software program that processes input.

• A device that stores data permanently.

Give two examples of input devices.

• Keyboard, Mouse

• Projector

• Scanner

• Printer

What is an output device?

• A hardware component that inputs data into a computer.

• A software program that manages computer resources.

• A device that stores data permanently.

• An output device is a hardware component that displays or produces data from a computer.

Name two common output devices.

• Webcam

• Speaker

• Monitor, Printer

• Scanner

What is the difference between data and information?

• Data and information are the same thing.

• Data is processed information; information is raw facts.

• Data is raw facts; information is processed data with meaning.

• Data is always accurate; information can be misleading.

How is data transmitted from one device to another?

• Data is transmitted solely via visual signals like smoke signals.

• Data is transmitted using encoding, communication mediums, and protocols.

• Data is transmitted through random noise and interference.

• Data is transmitted using physical mail and packages.

What role do input devices play in a computer system?

• Input devices are responsible for processing data.

• Input devices are used solely for data storage.

• Input devices play a crucial role in enabling user interaction with a computer system.

• Input devices only display information to the user.

Can you list three types of data?

• Quantitative data, Qualitative data, Categorical data

• Statistical data

• Descriptive data

• Numerical data

What is the purpose of an output device?

• To input commands into the computer

• The purpose of an output device is to display or produce the results of computer processing.

• To store data permanently

• To connect to the internet

How does information transmission occur in a network?

• Information is transmitted through physical cables only.

• Routing is unnecessary for local network communication.

• Data is sent in a continuous stream without packets.

• Information transmission occurs through data encoding, packet switching, and routing to the destination.
