An evolutionary click

You power on the computer, a completely dark black screen welcomes you, a blinking grey box staring back, expecting you to type something.  No there is nothing wrong with your computer, just a quick trip down memory lane, if you remember this scenario as soon as you power on your computer, then you, like me, are probably over 30 and can probably better appreciate today’s operating systems which are light years ahead of the old systems.

Operating systems as we know them today, such as Windows or Apple’s iOS rely on a Graphic User Interface (GUI) system to interact with it’s human operators, using icons to represent files, compared to the old Command Line Interfaces (CLI) such as the Microsoft DOS which ran on most IBM compatibles and relied completely on specific typed-in commands to access files.
