Binary              : 1011   0111   1100   0101
Decimal(4digts): 11 7 12 5 (For Manual use)
Hexadecimal : B 7 C 5

Binary (1011011111000101) = Hexadecimal (B7C5)

Here I converted binary to hexadecimal easily. Try to decimal.

Binary : 1 011 011 111 000 101

Decimal(3digts) : 1 3 3 7 0 5

Octal : 1 3 3 7 0 5


Binary (1011011111000101) = Octal (133705)

Here I converted binary to Octal easily. Am I right or wrong ?

Question is stereotype. Convesion to octal is more easy for human but not more common for programmers

Hello Ranjith you are right but binary to hexa-decimal is conversion is easy when comparing octal.

Because it calculation by 4 digits. For the same example

(1011 0111 1100 0101)2 = (B7C5)16.

I feel this is more of a mathematical question than a programming question. Since this is a 32 bit number, there is no need to convert at all. I feel the question is quite vague where answer could be true depending on the context in which the person who answers perceives the question

Niziak you follow the two steps first u convert into decimal and then to octal do u think this one is easy.......

Is this explanation correct "Hexadecimal system is better, because each 4-digit binary represents one Hexadecimal digit. ".

Because, even I can say that each 3-digit binary number represents one octal digit.

I can't understand how the hexadecimal is easy?why octal is hard?

Can anyone can explain it?

In hexadecimal only four letters required to represent, hence it is easy. Note, in octal it is represented with six digits ?
