HOW TO USE A COMPUTER

Thanks very much whoever came up with this ,,,,Really I have learnt many things just in one module

Firstly ,I thought that to power off a PC , I should not waste time i just need to press the power button,, not knowing that i was doing a wrong thing.

And i didnot know that you can be much faster while using a keyboard through its shortcuts than using a mouse ,,,,,, i really appreciate
