Today digital circuits and modern computers play a very important role in our day to day life. Boolean logic or digital logic is the foundation of these modern digital computers. Boolean algebra is used to analyze and simplify these digital circuits. Boolean Algebra was developed by George Boole in the mid 1800's.
Boolean algebra use's the binary number system i.e 1's and 0's. Variables used in boolean algebra can have only two values, binary 1 for (HIGH or TRUE) and binary 0 for (LOW or FALSE). In boolean algebra everything is in terms of 0's and 1's only.
Example : 1 for the switch is on & 0 for the switch is off , 1 for current is 20 mA & 0 for the current is 2 mA. The rules of boolean algebra are different from those used in our conventional algebra. There are no negative numbers, fractions, square root, logarithm, squares etc. Arithmetic operations like addition, subtraction, multiplications etc. are not performed in boolean algebra.
