Answer 2

hey, hex editor lets you see the contents of any file, that is its bytes, in hexadecimal format as opposed to decimal format to which we are normally used to. Each byte (a byte consists of variation of 8 bits and a bit is just 2 values (yes/no or 0/1 or whatever)) is simply a number that you can write in different formats. For example the number 160 (decimal format) can be written as A0 or 0xA0 in hex. The letters are just numbers written in one character. It goes like this: 0, 1, ... 8, 9, A (10), B (11) ... F (15). In order to convert hex to decimal you go from right to left and raise the power of 16, so A5 = Pow(16,0)*5 + Pow(16,1)*A(=10) => 165. To write any byte, you don't need more than two places long hex. Highest two placed hex is FF (255) and lowest is 00 (0).
