Question:

What is abstraction in computing? Give an example of how it works.

Amir F.
Answer:

Abstraction is when functionality of some parts of a system are hidden from other parts of the system. For example, when a driver starts his car - he does not need to know about the inner workings of a combustion engine, he simply turns his key and the ignition starts. In this example the engines functionality is hidden from the driver.
