Number Systems and Codes - Technical MCQs

Q1:

What is the difference between binary coding and binary coded decimal?

A Binary coding is pure binary.

B BCD is pure binary.

C Binary coding has a decimal format.

D BCD has no decimal format.

ANS:A - Binary coding is pure binary.

Binary coding involves methods to code the numbers from decimal system into pure binary system. Whereas binary coded decimal system also has the 1s and 0s but only using specific weights assigned to the 4 bit-system used in it. In binary coded decimal we use the weights 8,4,2,1 to find out the bcd(binary coded decimal)of any digit. BCD system has only 0 to 9 as valid digits.
