BCD is

  • A.Binary Coded Decimal
  • B.Bit Coded Decimal
  • C.Binary Coded Digit
  • D.Bit Coded Digit

Answer: A

Correct answer: Binary Coded Decimal

BCD encodes each decimal digit separately in four bits, so 59 is stored as 0101 1001 rather than as the binary 111011. It wastes space, since six of the sixteen combinations are unused, but it converts to and from decimal without rounding - which is why it survives in financial and display applications.
