Hardware and Software are two basic concepts in the computer world.
TL; DR
Hardware is what you can throw kicks at.
Software is what you can only get angry with.
The Hardware
The hardware is basically the physical computer itself and the devices it make use of.
People also refert to it with hw.
It's the device you interact with, or the thing you can plug in the computer.
Like the monitor you're reading this from, or your computer's keyboard (the one you can touch).
The software
The software is represented by code instructions, that can instruct the computer's processor on how to do.
It can also found to be written as sw.
An example of software is the browser you are using right now (Chrome, Firefox, Safari, Opera, Vivaldi, etc...).
Another example of software is also the virtual keyboard on your smartphone or tablet you type on. Being virtual, it is considered software.
Also, a more complex software is the Operating System.
