Although Bill Gates denies making this statement, it does show how significant the breakthrough from 64K to 640K of computing memory felt to those in the computing industry at the time (the early 1980s). In the event, within five years of the arrival of 640K this level of memory was considered far too small and memory has expanded almost exponentially since then. One of today’s mobile phones has more memory than the computers that filled whole rooms in the 1970s.
