Abstract

As we mentioned on page 32, all instructions, texts and data we pass on to the computer have to be converted into zeros and ones in accordance with a specific coding system, before the CPU (see page 13) can do anything with them. Such a system consisting of no more than two values is called a binary system. In the binary system, the numeral 2 is represented by 10, 3 by 11, 4 by 100, 5 by 101, 6 by 110, 7 by 111, 8 by 1000, 9 by 1001, 10 by 1010, etc.
