I’m an IT guy and love everything about computers, as long as they’re made by a company that uses a piece of fruit as their logo. I thought I could expand the knowledge of cachers by presenting information about units of measure for computers. The megabyte is a multiple of the unit byte for digital information. The unit symbol for the megabyte is MB. The prefix mega indicates multiplication by the second power of 1000 and therefore one megabyte is one million bytes of information.
