Binary-Coded Decimal

Binary-Coded Decimal (BCD) is a method of representing decimal numbers (0-9) in a binary format, which computers use for processing. In BCD, each decimal digit is stored as a separate group of four binary bits. For example, the decimal number 25 would be represented in BCD as 0010 0101, where 0010 represents the digit '2' and 0101 represents the digit '5'. This approach simplifies calculations and displays because it maintains the decimal structure, making it easier for humans to read and interact with numerical data while allowing computers to perform operations using binary.
