Hey there, so I'm studying computer systems management in College and have a paper ready to hand in except for one question on it. Any Ideas?:confused:


Outline 3 applications of the following numbering: binary, octal and hexadecimal systems to real life situations.
 
For hexadecimal what about web development and colour palettes?

For octals you could use UTF-8 encoding tables.

I hope you are joking, UTF-8 is base 256, octal Ives you the 8 numerical digits 0 through 7, which makes for a pretty useless character set!

This is a bit stupid because all convention computers are binary and. Thus octal and hex are encoded as base2 internally, so any answer to the others applies too binary.

Putti that aside, binary has some uses in things like gray encoding. Say you have a set of M variables that can be in 2 different states, then you can encode this as a m-length bit string where the the N-1 digit represents variable N's state. Natively you would really want this represented as a32/64bit word etc. This is an easy linear encoding system that has some uses in machine learning, optimization etc. E.g. In a neural network that is trying to categories images of animals and there are 15 different animals then the training set can include vectors of length 15 where each digit is 0 except for the animal the image represent etc. This can make the math simpler.


For hex, it is the smallest base that can represent all 10 numerical digits. It has some nice properties, e.g. A pair of them is a byte. If a byte has to be represent in ASCII, e.g. in html, then 2 hex characters represent the full 256 values compared to an RGB encoding where you need 3 characters


With octal I've never really see a Good real world use in my career.
 
arinc 429 labels use octal. Hex is a lot easier when being explicit for binary values >8 bit. And binary well all digital electronics.
