Chapter 2 Quiz: Input & Output Devices

Is a keyboard an input or output device?

• Input device

• Output device

• Both input and output device

• Neither input nor output device

What is the difference between an input device and an output device?

• Input devices display data, output devices enter data

• Input devices store data, output devices process data

• Input devices are used to enter data and instructions, output devices display or produce results of processed data

• Input devices are only used for gaming, output devices are used for printing

What is the purpose of an output device, and what are two common examples?

• To store data; examples are keyboard and mouse

• To display visual output; examples are monitor and printer

• To process data; examples are CPU and RAM

• To input commands; examples are scanner and microphone

What are some input and output devices you can use at home?

• Input: Keyboard, Mouse; Output: Monitor, Printer

• Input: Monitor, Printer; Output: Keyboard, Mouse

• Input: CPU, RAM; Output: Hard disk, SSD

• Input: Speaker, Microphone; Output: Scanner, Webcam

Which device is considered an output device?

• Mouse

• Printer

• Touchpad

• Keyboard

What is the function of an input device?

• To display results

• To provide data and control signals to a computer

• To print documents

• To store information

What is the main purpose of an output device?

• To receive data from the user

• To display, print, or transmit the results

• To store files

• To process information

What is the difference between input and output devices? Provide two examples of each.

• Input devices allow users to input data into a computer (e.g., Keyboard, Mouse), while output devices communicate results to the user (e.g., Monitor, Printer).

• Input devices store data (e.g., Hard drive, SSD), while output devices process data (e.g., CPU, RAM).

• Input devices print documents (e.g., Printer, Scanner), while output devices display images (e.g., Monitor, Projector).

• Input devices connect to the internet (e.g., Router, Modem), while output devices save files (e.g., USB drive, CD).

The function of the CPU in relation to input and output operations is to:

• Process input data from input devices and send output data to output devices, controlling overall input/output operations.

• Only store data and not interact with input or output devices.

• Display images on the monitor.

• Print documents directly from the computer.

What is the difference between analog and digital signals in the context of input and output devices?

• Analog signals are continuous and vary smoothly, while digital signals use binary values (0s and 1s).

• Analog signals use binary values, while digital signals are continuous.

• Both analog and digital signals use binary values.

• Analog signals are only used in printers, while digital signals are used in microphones.
