As we know BCD(binary coded decimal) numbers representation are used in computers.
With the 4-bits space you can able to address 16 numbers.But in BCD number system you only addressed 10(0-9) numbers.
Can any one tell me what about the other 6 addresses...?
Is it loosed....?
Why don't we use hexadecimal number system for representation ?

    Well..as far I know the processor uses BCD system only for representaion & not for actual calculations & addressing.That happens in HEX format.
    As for BCD after adding 6 it becomes readily available ofr addition-subtraction, also the same in hex is quite complicated so BCD is better for represenational purposes.
