In operation of binary number from 1 digit to 2, 4 and 8 digits cause the new
variables as follows :
(1) bit : It is binary number one digit or call binary digit. There are 2 numbers
as 0 and 1.
(2) byte : It is 8 binary digits or bits.
(3) LSB : Least Significant Bit : It is last right digit of binary number. The digit
weight is lowest as 20. If this bit as “1”, the value is equal 1 x 20 = 1 x 1 = 1. If as "0", the
value is equal 0 x 20 = 0 x 1= 0
(4) Digit or Bit assignment : The last right digit is assigned to Bit 0 (b0) or LSB.
Next bit is assigned to Bit 1 (b1) and count to left order until complete.The 8-bit assignment
is b7 b6 b5 b4 b3 b2 b1 b0
(5) MSB : Most Significant Bit : It is last left digit of binary number. In 8-bit
number, the MSB is bit 7. The digit weight is 27 or 128. The digit weight would be change
following the number of digit.
