Octet (ConceptClass, 5)
From Compile Worlds
An octet is, as you might have imagined, a sequence of eight bits. Affectionally called a byte, it's overrated and yet another of those silly standards that's come into place just accidentally and stayed forever since. Luckily, there are still quite a few systems which are independent of the word size and do not have any concept of octets, such as networking.
File sizes are most commonly expressed in terms of octets instead of bits, leaving comparisons between file size and Internet speeds (which are measured in bits) very confusing to most.
