Binary System

Binary System:

A computer does not use the decimal system to display numbers. Instead it calculates in the binary system.

In the decimal system a position can take a value between 0 and 9. In the binary system a position can only

take 0 or 1. A computer relies on the binary system because its elementary electronic components can only

accept two statuses.

Bit:

A computer's electronic components work like little switches which can be either in the "ON" or "OFF"

position. This means that one of these components can represent a single-digit binary number and the two

possible switch positions then correspond to the values 0 and 1. A single binary figure, which can contain the

value 0 or 1, is known as a bit.

A computer requires a binary number with more than one digit to display more than two values. It can display

four different values, for example the numerals 0 to 3, using a two-digit binary number. Using a three-digit

binary number, the computer can display numerals 0 to 7, for example. In order to display every numeral in

the decimal system, i.e. 0 to 9, the computer needs a four-digit binary number.

Byte:

8 bits, that cover 256 different values, are united to an independent order. That is why a separate name was

introduced for 8-bit values, the byte. Just as you can simply say "a pound" instead of "16 ounces" you can

also simply say "a byte" instead of "8 bits".

A byte is used in digital image processing to represent grey scales or the shades in the color channel such as

red, green or blue. For example the transition from black to white can be represented in a total of 256 stages.

You can also use the term 8-bit color depth. This shading is so fine that the human eye no longer perceives

the individual shades and it therefore gives the illusion of a smooth transition. A picture in a shade of grey

needs 1 byte of memory space per pixel so that each pixel can be assigned one of the 256 gray scales.

A color image in the RGB color space needs 3 bytes of memory space for each pixel - a byte for each shade

of the colors red, green and blue. As a color tone is represented with 3 bytes, i.e. 3 times 8 bit, the term 24-bit

color depth is used.
