We will use ’ ⋅’ to designate the AND operation. AND - a binary operator the result is 1 if and only if both operands are 1 otherwise the result is 0.Resulting value of the Boolean operation(s) for each variable combination is shown on the respectiveĮlementary algebra has four operations, addition, subtraction, multiplication, and division, but Boolean A truth table lists all possible combinations of the variables in the problem. Since there are only two values, a truth table is a very useful tool for working withīoolean algebra. There are only two values, 0 and 1, unlike elementary algebra that deals with an infinity of values, the For a more theoretical approach, including discussions of more generalīoolean algebra concepts, search the internet, or take a look at books like, ,, or Pragmatic approach of starting with the basic properties of Boolean algebra, then explore the Mathematical tools needed for working with switching circuits from them. Some authors start with the postulates of Boolean algebra and develop the There are many approaches to learning aboutīoolean algebra. Learn another algebra system - Boolean algebra. In order to understand how the components are combined to build a computer, you need to The hardware devices that implement the logical operations are called
Limit the discussion to electronic computers, which use transistors to switch between two different voltages. This chapter provides an overview of the hardware components that are used to build a computer.
