How do you represent images in binary

All data is encoded in binary––1 (status of on) and 0 (off status).  Color images are composed of group of color, with different amounts of red, green, and blue (ranging from zero to 255). Different values of these colors make up a single pixel. Thus, Image files contain millions of these color combinations. Each color channel is represented by eight bits. Eight bits = 1 byte.   One color channel, red, green, or blue is represented by 8 bits or one byte.  For example, blue is 01100110.  

Data in computers is stored and transmitted as a series of ones and zeros (also known as Binary). To store an image on a computer, the image is broken down into tiny elements called pixels. A pixel (short for picture element) represents one colour.
