How many bytes in a hex value

WebA byte is a group of 8 bits. A bit is the most basic unit and can be either 1 or 0. A byte is not just 8 values between 0 and 1, but 256 (2 8) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111. Thus, one byte can represent a decimal number between 0 (00) and 255. Puzzled? There is some standardization of using spaces (rather than commas or another punctuation mark) to separate hex values in a long list. For instance, in the following hex dump, each 8-bit byte is a 2-digit hex number, with spaces between them, while the 32-bit offset at the start is an 8-digit hex number.
