A collection of simple concepts explained with simple words to explain what happens under the hood when you click or tap on the screen of your home device: what your phone or computer asks for, how the information travels back and forth and what happens kilometers away before a picture of the cutest cat of the Internet is displayed on your screen.

The idea is to give a simple view that the general public can understand about how computer centres like ours work, how humans manage them and why they're necessary for their daily lives.
