BCD

BCD stands for Binary Coded Decimal and is a form of coding in which each decimal digit is represented by a group of 4 bits. Unlike other binary coding forms, such as the binary number system, which directly uses binary numbers for each decimal digit, BCD allows decimal numbers to be represented directly in binary form.

In BCD, each decimal digit from 0 to 9 is represented by a corresponding 4-bit binary number. For example, the decimal digit “5” is encoded as “0101” and the decimal digit “9” as “1001”. This enables simple conversion between decimal and binary representations of numbers without complex calculations.

BCD is used in various applications, especially in digital data processing and in electronic systems that work with decimal numbers. A common example is the use of BCD in digital displays, such as digital clocks or calculators, where decimal numbers need to be represented directly in binary form.

Another area where BCD is used is the storage of decimal numbers in digital systems. By using BCD, decimal numbers can be stored and processed precisely and efficiently without the need for conversions between different number systems.

Overall, BCD is an important form of coding in digital data processing that enables decimal numbers to be represented directly in binary form. Its applications range from simple digital displays to complex electronic systems where precise and efficient processing of decimal numbers is required.
