I'm really getting annoyed at people using a lowercase b to refer to byte. It's a capital B, get it right people. It's especially annoying when self-proclaimed computer experts can't even get it right, what's even worse is when they write a big piece using them and get them all wrong, and then just claim they made 70 typos!

50Kb/s is not equal to 50KB/s.

What are bits and what are bytes.
