Hex is used in mathematics and information technologies as a more friendly way to represent binary numbers. Each hex digit represents four binary digits; therefore, hex is a language to write binary in an abbreviated form.
Four binary digits also called nibbles make up half a byte. This means one byte can carry binary values from to In hex, these can be represented in a friendlier fashion, ranging from 00 to FF. In html programming, colors can be represented by a 6-digit hexadecimal number: FFFFFF represents white whereas represents black.
Originally developed from telegraphic codes, ASCII is now widely used in electronic communication for conveying text. As computers can only understand numbers, the ASCII code represents text characters with different numbers. These are the 26 letters of the English alphabet both in lower and upper cases ; numbers from 0 to 9; and various punctuation marks.
The string for a given hex number will depend on the programming language of the string. Theoretically you can invent your own alphabet and language, encode it and produce strings. In ASCII, which is one of the most common encoding systems, a few conversion examples are as follows:. That make sense. You're welcome. Perhaps there are terminal control characters that may need to be preserved. In addition, strings likely doesn't preserve strings with utf-8 characters.
David C. Rankin David C. Rankin If you've used python, for a character like a newline str b [] converts a bytes object that looks like b'abcd' to abcd. The b and ' s are not important for output and so are truncated. Additional bash usage notes You are probably getting an extra newline in your output when sending to xxd.
