|What do you mean by one hex digit?|
|Sundar said: (Feb 10, 2012)|
0xAF Here A is a hex digit and F is a hex digit.
A represents 10 in decimal or 1010 in Binary.
F represents 15 in decimal or 1111 in Binary.
AF combination represents 175 in decimal or 10101111 in Binary (1 byte of information).
Here each hex digit represents 4 bits, nibble is consist of 4 bits.
Hence the answer.
int a = 175;
int a = 0xFA;
Here both of the above statements are same.

|The digits from A to F can be represented by 4 bits. So
Any hex digits take 4 bits.

|1 hex = 16.
Nibble = group of 4 bits.
Then how One hex digit is sometimes referred to as a (n) : Nibble.

|All hexadecimal number starting from 0=0000, 1=0001, 2=0010, 3=0011 & soon till A=1010, B=1011, C=1100, D=1101, E=1110, F=1111 i.e upto F.
All digits of hexadecimal number system can be represented in 4 digits not more than that needed,
& 1 nibble = 4 bits,
Hence 1 hex digit sometimes referred to as nibble here in the Qus as a(n).

|Binary number system has 2 characters.
Decimal number system has 9 characters.
Octal number system has 8 characters.
Hexa Decimal number system has 16 characters.
Bit = 0 or 1;
Nibble = 0000 to 1111 ; (any 4 bits btw these).
Byte = 0000 0000 to 1111 1111 (any 8 bit btw those limits).
Similarly, Word = any 16 bit.
So the maximum value of hexadecimal number system is F.
And the equivalent value of F in binary is 1111.
Which is the maximum value for a nibble. And so a hex can be referred as a nibble.
