Hello!
Think of a machine. You put something in. This is the input. The conversion process is whatever goes on inside the machine. Let's say that the machine will spray paint a vase you put into it. The vase is the input. The spray painting is the conversion process. What comes out of the machine, or the result, is the output. In our example it would be the painted vase.
The conversion process changes the input into the output.
For example, think of a function, or a table. Let's say that we have the rule, +1. Let's say our input is 1. The conversion process is +1. This makes 1 become the output of two.
I hope this helps!
