Diagrams used to represent logical concepts have been around in one form or another for a very long time. For example, the Greek philosopher and scientist Aristotle (384 BC to 322 BC) was certainly familiar with the idea of using a stylized tree figure to represent the relationships between (and successive sub-divisions of) such things as different species. Diagrams of this type, which are known as the Tree of Porphyry, are often to be found in medieval pictures.

Intel introduces the Pentium chip. (in fact it's Intel's 586) An increase of 200% in power of the processor, as is announced by the manufacturers can not be realized. Tests showed that even a 20% increase is not possible with the standard (386/486 or 64020/30/40) available software. The Pentium is plagued with problems. For example a cooling is mandatory because of problems with over heating. The pentium is the first cpu for micro computers with a kind of parallel processing.
Quantum computers promised to solve some of the most difficult mathematical problems exponentially faster than a conventional computer
