What’s Up With The On/Off Symbol On Your PC?

Have a look at the control buttons located below your monitor screen and you’ll see a symbol comprising a vertical line partially breaking through the upper part of the circle, and that, as you know, is the On/Off symbol. But, why a symbol so complicated? Why not something simple? No matter how meaningless the symbol may seem to you, it is there for a reason.

History-On/Off SymbolHere is a bit of a history on how the symbol came into existence. In case you didn’t know, computer understands the language of 0s and 1s. Every command you input is converted into 0s & 1s. The conversion is physically not visible, as all of this happens behind the scenes. These 0s & 1s are then converted again into manually interpreted language and are then displayed on your screen. Was this too much to handle? Well, don’t you worry!! This was just to inform you on how a computer talks to humans.

Let’s be a bit more precise. In technical terms, 1 means the circuit is active, in easy words, it it turned ‘ON’. 0 on the other hand is just the opposite – the circuit is turned ‘OFF’. So, the line and the circle in the On/Off symbol is basically a 0 and a 1.

Browse the internet for a while and you might probably come across a few weird (or call them dumb) interpretations of the same. They are the most funniest you would ever come across. Have a read, and you’ll realize there is something wrong. So, make sure you stick to the 0s and 1s theory and that is all you need to know.
