1. The Abacus 3000 B.C. – The abacus is probable
considered the original mechanical counting device (it
has been traced back 5000 year). It is still used in
education to demonstrate the principles of counting
and arithmetic and in business for speedy calculation.

The Honeywell 400 and the Second Generation of
Computers – The invention of the transistor signaled
the start of the second generation of computers (1959
– 1964). Honeywell established itself as a major
player in the second generation of computers.
12.
The Third Generation of Computers – The third
generation was characterized by computers built around
integrated circuits.
13.

The Apple II – Not until 1975 and the
introduction of the Altair 8800 personal computer was
computing made available to individuals and very small
companies. This event has forever changed how society
perceives computers. One prominent entrepreneurial
venture during the early years of personal computers

was the Apple II computer (shown here). Two young
computer enthusiasts, Steven Jobs and Steve Wozniak
(then 21 and 26 years of age, respectively),
collaborated to create and build their Apple II
computer on a makeshift production line in Jobs’
garage.
15.
Bill Gates Microsoft 1975 – In 1968, seventh
grader Bill Gates and ninth grader Paul Allen were
teaching the computer to play monopoly and commanding
it to play millions of games to discover gaming
strategies. Seven years later, in 1975, they were to
set a course which would revolutionize the computer
industry. While Harvard, Gates and Allen developed a
BASIC programming language for the first commercially
available microcomputer, the MITS Altair. After
successful completion of the project, the two formed
Microsoft Corporation, now the largest and most
influential software company in the world. Microsoft
was given an enormous boost when its operating system
software, MS-DOS, was select for use by IBM PC.
