Question: BCD is

Answer:

BCD stands for Binary Coded Decimal. BCD is a binary representation of decimal numbers, where each decimal digit is represented by a four-bit binary code.

In BCD, each decimal digit from 0 to 9 is represented by its corresponding four-bit binary value. For example:

0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001

BCD is often used in digital systems, particularly in applications that require precise decimal representation, such as digital clocks, calculators, and numerical displays. BCD representation allows for direct conversion between binary and decimal values and simplifies decimal arithmetic operations in digital circuits.
