Why do computers use binary instead of decimal?

In binary numbers, instead of each number place is multiplied by ten, they are multiplied by two. This allows long strings of number to still be translated into standard numbers and letters. Eight binary number strings are the most useful and most used set of binary numbers. The eight-number sets allow the computer to process numbers from zero to 255. These eight numbers are also the smallest binary sets that give the right amount of number options to represent letters. This is similar to how the binary numbers are used to represent pictures. Pictures are made up of pixels, which are digital representations of the picture. The pixels coincide with binary codes, which tell the computer how much red, blue or green is needed to create the color on the screen. Each pixel is normally represented by up to three bytes or three of the eight digit binary codes.
