Convert Hexadecimal To ASCII or ASCII to Hexadecimal:

Bits, Bytes, Binary, and Hexadecimal - Basic Storage Data

Binary Numbers are all zeros (0) and ones (1).
In binary, each digit position represents a power of 2.

Binary integers are stored in multiples of 8 bits (8, 16, 32, 48, 64)

8 bits == 1 byte
16 bits == 2 bytes
32 bits == 4 bytes
48 bits == 6 bytes
64 bits == 8 bytes

One binary digit --> 0 == 1 bit
Two binary digits --> 00 == 2 bits
Four binary digits --> 0000 == 4 bits
Eight binary digits --> 0000 0000 == 8 bits
Sixteen binary digits --> 0000 0000 0000 0000 == 16 bits

Hexadecimal Numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F):
In hexadecimal, each digit position represents a power of 16.

Each hexadecimal digit represents 4 binary bits.
Remember: 1 byte == 8 bits, therefore...

One hexadecimal digit represents 4 binary bits, which is equal to half a byte.
Two hexadecimal digits together represent 1 byte, which is equal to 8 bits.
Four hexadecimal digits together represent 2 bytes, which is equal to 16 bits.
Eight hexadecimal digits together represent 4 bytes, which is equal to 32 bits.
Twelve hexadecimal digits together represent 6 bytes, which is equal to 48 bits.
Sixteen hexadecimal digits together represent 8 bytes, which is equal to 64 bits.

Possible numbers and digits for the four systems

		 System			 Base		Digits

		 Binary			 2		0,1
		 Octal			 8		0,1,2,3,4,5,6,7
		 Decimal		 10		0,1,2,3,4,5,6,7,8,9
		 Hexadecimal		 16		0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
