Question

1.Give one example of an input

2.Give one example of an output
3. Why are those examples inputs and outputs?

Answer 1

An input is raw material such as timber, while an output is a finished product like a chair. These examples illustrate the transformation process within a system where an input of energy, such as electricity, is used to operate machinery.

Step-by-step explanation:

An example of an input is raw material, such as timber for a furniture manufacturing process. An example of an output is the finished product, like a chair that has been made from the timber. These examples represent inputs and outputs because they show the transformation process within a system. In every process, there is usually an input of energy; for instance, the energy required to operate machinery cutting the timber comes from electricity which is the source of the energy input into the system. The interaction between the system and its environment is shown by the electricity being conducted through machines to perform work on the raw materials.

Answer 2

Input: Keyboard, mouse, microphone

Output: monitor, loudspeakers

Input & Output: Network devices, Hard disks, USB drives, touch screen

Step-by-step explanation:

Input devices are anything which provides information for a computer to act upon. The most common examples for a computer are the keyboard and mouse/trackball.
