Example 4

hard
Describe three different input devices and three different output devices a computer program might use. For each, give an example of a program that uses it.

Solution

  1. 1
    Step 1: Input devices: keyboard (word processor), mouse (drawing app), microphone (voice assistant). These capture data from the user or environment.
  2. 2
    Step 2: Output devices: monitor (web browser), speaker (music player), printer (document editor). These present results to the user.
  3. 3
    Step 3: Some devices are both input and output, like a touchscreen (smartphone app).

Answer

Input: keyboard, mouse, microphone. Output: monitor, speaker, printer. Programs use combinations of these for user interaction.
Understanding physical input and output devices connects software concepts to hardware. Modern programs often use multiple input and output channels simultaneously.

About Input/Output

The mechanisms by which a program receives data from the outside world (input) and sends results back (output). Input can come from keyboards, files, sensors, or network connections; output can go to screens, files, printers, or other devices.
