Q1:

Binary numbers need more places for counting because

A They are always big numbers

B Any no. of 0's can be added in front of them

C Binary base is small

D 0's and l's have to be properly spaced apart

E None of the above

ANS:C - Binary base is small

Lets take an example.

50 in BINARY corresponds to "110010" ( i.e 6 bits/digits).
50 in HEXADECIMAL corresponds to "32" ( i.e 2 bits/digits).

So if base is small the number is big(say lengthy) and vice-versa.

Similarly we can calculate for octal and decimal.
