Binary system employs 2 as the base, So requiring only two different symbols for its digits, 0 and 1.
Also called as "base 2" numbers. The digits have a value specified which is equal to base number (2)^0,1,2,3,4,5,6.........n from right to left.
One binary digit is called bit. It is the smallest unit of binary system.
The lowest order bit is called Least Significant Bit and the highest order bit is called Most Significant Bit.
How to convert binary to decimal?

Binary System in Computer Based Devices?
Binary numbers are used in digital electronics circuits in computer based devices where the logic gates can either turn on or off ( 0 = Off and 1 = On).
Bit is the smallest unit of data on a computer, each bit has a single value of either 0 ( low or off ) or 1 ( high or on).
