Hi!
The mouse and the keyboard are <em>input devices. </em>By using them, we can input data which will give us a (hopefully) desired output!
For example...
Just by using my keyboard to type, I'm inputting data in the form of ASCII characters and symbols.
By using my mouse to click on an area so I can move this sentence on a new line, I had to input a request to do such!
Hopefully, this helps! =)
