Which components are considered input and output devices?

Which components are considered input and output devices?

• A. A device that outputs graphics to a monitor
• B. Keyboard, mouse, printer, etc.
• C. RAM
• D. CPU

Answer: (B)

The main idea is identifying items that serve as both ways we interact with a computer: input devices send data to the computer, while output devices present results from the computer. A keyboard and mouse are classic input devices that convert our keystrokes and movements into digital signals the computer can process. A printer is an output device that takes digital data and produces a physical copy. The option that lists keyboard, mouse, printer, etc., includes examples of both input and output, showing a mix of ways we interact with a computer. The other options point to internal components (RAM, CPU) or describe only one type of device, not a combination of input and output capabilities.
