Representing data

All data inside a computer is transmitted as a series of electrical signals that are either on or off. Therefore, in order for a computer to be able to process any kind of data, including text, images and sound, they must be converted into binary form. If the data is not converted into binary – a series of 1s and 0s – the computer will simply not understand it or be able to process it.

Before a computer can understand any information, it must first be converted into binary. Audio, video, images or written text must be converted from their original formats into binary code.

Representing text

When any key on a keyboard is pressed, it needs to be converted into a binary number so that it can be processed by the computer and the typed character can appear on the screen.

The letter "A" on a keyboard converts to 01000001 in binary

A
