Take a look at what is being prepared here.
Lemon Water Sugar Lemonade
It’s Lemonade! The things that we put inside the glass are inputs and the lemonade
that we got is the output.
So, lemon, sugar and water are the inputs and the lemonade that we get is the
output.
Therefore, the action that takes place with the inputs is known as processing. The
results that we get after processing is known as output.

Similarly, we give instructions to the computer, the computer then works on the
instructions and gives us the result. The instructions that we give to the computer
are called input. The working of the computer is called processing and the result we
get is called output.
