In this digital world of electronics, the information is stored in the form of bits (Binary). Certain arithmetical operations like addition, subtraction, multiplication, and division are to be performed on these bits.  The combination of 'Arithmetic Operation' with certain 'logic' using binary numbers was established by Leibniz. Further, the electrical circuits of switching based on vacuum tubes were designed. The invention of relays replaced the 'vacuum tubes' in switching circuits. Finally, … [Read more...]
