What is the use of Boolean Algebra in Computer and how it works?

Question

Please Explain me clearly and easily

Answer 1

If you work with low level programs or plc programming you should know them otherwise it is not use in simple apps and programs.

In boolean algebra values are just 0 and 1

0+0=0
0+1=1
1+1=10

As you can see they are all in base 2

As you know our base 10 numbers are 0-9

In base 2 they are 0-1
