How many hexadecimal values does it take to represent a byte?
its home work and i cant find it in my book
A byte is normally 8 bits. A hexadecimal number has a value from 0 to 15, its base is 16 - hence the name 'hexadecimal'So a byte is represented by two hexadecimal numbers. For example, the hex number 0x23 is binary 0010 0011 and has a decimal value of 2x16 + 3 = 35.
One (if memory serves)16 bits or 2 bytes for the first place value...256 bits or 32 bytes for the second place value. and so on...
A byte will be represented by between 0 and 255 decimal or two hexadecimal digits. You can read on these representations on http://en.wikipedia.org/wiki/Hexadecimal.
