One nibble is equal to 4 bits.

What do you mean by one hex digit? 
Sundar said: (Feb 10, 2012)  
@ALL 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. Note: 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 A =1010 B=1011 C=1100 D=1101 E=1110 F=1111 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.
