What is input and output data

Question

hello im a 15 years that is trying to learn how to code^_^ im a newbie in this....hope that i can get an explanation

Answer 1

Input data is something which the system receives.
For example : A button or a text-box that requires the user to write something on it.

Output data is something which the system does.
For example : Opening an application when you click on a button Or Helping you to write out something upon clicking a button.

Both are closely linked as without input, there will be no output. The simplest form of input as simple as pressing the 'run' button on the system. The simplest form of output can be as simple as writing a "Hello world" on the Console itself.
