What's the difference between a "bit" and "octet"?
python-3.x
Solution
A bit is a single binary digit.
An octet is a collection 8 bits, sometimes called a "byte". There is no formal definition of a byte as 8 bits (though it is the generally accepted standard). The term octet is used when it is necessary to unambiguously specify that there are only 8 bits in the collection.
Problem
What's the difference between a "bit" and "octet"? Some python books, depending on the author, seem to use the terms interchangeably. I asked a PHD level guy and he said there was a difference but didn't explain what the difference was.
