Binary Coded Decimal (BCD) is a system that encodes each decimal digit individually into its binary equivalent using a four-bit pattern. For example, the decimal number 64 is represented in BCD as 0110 for 6 and 0100 for 4. This method allows for the straightforward representation of decimal numbers in binary form.

1. What is Binary Coded Decimal
Solution
Binary Coded Decimal is a system for coding a number in which each digit of a decimal number
is represented individually by its binary equivalent.BCD takes advantage of the fact that any one
decimal numeral can be represented by a four bit pattern
For e.g. to represent 64 decimal in BCD form each digit of number will be seperately represented
in binary as
6=0110
4=0100
64=0110 0100
