The microprocessor has changed a lot over the years, says (Michael W.
Davidson,http://micro.magnet.fsu.edu/chipshot.html) Microprocessor
technology is progressing so rapidly that even experts in the field are
having trouble keeping up with current advances. As more competition
develops in this $150 billion a year business, power and speed of the
microprocessor is expanding at an almost explosive rate. The changes
have been most evident over the last decade. The microprocessor has
changed the way computers work by making them faster. The
microprocessor is often called the brain of the C.P.U.(or the central
processing unit)and without the microprocessor the computer is more or
less useless. Motorola and Intel have invented most of the
microprocessors over the last decade. Over the years their has been a
constant battle over cutting edge technology. In the 80's Motorola won
the battle, but now in the 90's it looks as Intel has won the war.

Macintosh IIxIt
was invented by Motorola in the early 80's. The 68000 also had two very
distinct qualities like 24-bit physical addressing and a 16-bit data
bus. The original Apple Macintosh ,released in 1984, had the 8-MHz
found at the core of it. It was also found in the Macintosh Plus, the
original Macintosh SE, the Apple Laser-Writer IISC, and the Hewlett-
Packard's LaserJet printer family. The 68000 was very efficient for its
time for example it could address 16 megabytes of memory, that is 16
more times the memory than the Intel 8088 which was found in the IBM PC
. Also the 68000 has a linear addressing architecture which was better
than the 8088's segmented memory architecture because it made making
large applications more straightforward.
The 68020 was invented by Motorola in the mid-80's(Encarta 95). The
68020 is about two times as...
