In order to perform its function of fetching and executing instructions, the processor uses complex logic circuits. These are also called digital circuits because they work by processing binary digits. In this section, we study why computers use binary digits and we look at how basic components of the digital circuit, logic gates, are used to process this data.
Why use Binary?
A binary number system means that only two digits can be used. These two digits are 0 and 1.
Using only 0 and 1 makes it easier to design the electronic circuits that the computers will use. This is because, if the…
