PPT-Logic Gates

What are logic gates In the binary lesson we discussed the switches inside a computer Logic gates are the switches that turn ON or OFF depending on what the user is doing They are the building blocks for how computers work.

Boolean Algebra defined with a set of elements, a set of operators and a number of . axioms . or postulates.. A set if a collection of objects having a common property. Elements. We already know that the language of the machine is . binary. – that is, sequences of 1’s and 0’s. But why is this? . At the hardware level, computers are streams of signals. These signals only have two states of interest, high voltage and low voltage. . Logic Gates. NOT (Inverter) Gate. AND Gate. OR Gate. NAND Gate. NOR Gate. XOR Gate. Digital Signals. Digital signals 0 (false) or 1 (true). Digital signal 1 is represented by a small voltage.. Digital signal 0 is represented by no voltage.. . to Logic Gates and Logic Circuits.
