Logic Gates
Many people might not know what all these diagrams are or what their purpose is. These diagrams are know as logic gates and they play a key role. Their role is convert digital data in to analog data. Logic gates can be used to construct logic circuits. All logic gates have an input, which is represented by A and B and an output which is represented by F in the pictures on the left side. Logic gates are the simple building blocks of a computer. In fact there many logic gates in the most complex computer circuit. Computer microprocessor may contain more then a 100 million logic gates! All circuits have some kind of gate inside depending on how the circuit is built. In class we also made circuit and we also used logic gates to make the two LED s light up. We made different logic gates to make different LED s light up some logic gates we used include the AND gate, the NOR gate and the OR gate. By physically performing the experiment allowed me to fully understand the concepts of logic gates.
