3. These geniuses have been the most gifted people to the world
community who transformed the way we live and work today
4. Computer inventions that
date back to 2000 years
ago can't be compared with
the ones of this century,
but we simply can't neglect
the importance of even a
wooden Abacus machine
that laid the foundation of
future computers.
5. Charles Babbage: The Analytical Engine
invented an analytical engine in 1822.
"Father of the
Computer"
However, he couldn't actually build the
analytical engine, but was only able to
present it theoretically.
His unfinished work was completed
by scientists in 1930
His concept of analytical engine was
quite similar to the concepts of
modern-day computers that include
subroutines and input devices.
6. Alan Turing: The Turing
Machine
Although, he did not design any computer,
Alan Turing, an English mathematician
and computer scientist has been one of
the most influential personalities in the
field of computer science.
He provided a platform for formulating the
basic concept of algorithm and destined the
Turing machine, that was able to test the
intelligence of a machine.
In fact, he pioneered in the field of artificial
intelligence. Today's, CAPTCHA code test on
Internet and computers has evolved from
Turing's ideas.
7. Konrad Zuse: The Z Series
Computers
The German engineer, Konrad Zuse, in 1936,
invented the first electrical binary
programmable computer - the Z1, Z2, and Z3
were also introduced by Zuse in 1939 and 1941
respectively.
Unfortunately, Zuse's efforts were
destroyed during second world war.
8. John Vincent Atanasoff & Clifford
Berry: Atanasoff-Berry Computer (ABC)
Developed in the war phase of 1942,
Atanasoff-Berry Computer (ABC) was
the world's first fully electronic
digital computer.
Its inventors, John Vincent Atanasoff &
Clifford Berry shared the relationship
of a professor and a student.
John was an America
electronics engineer
while Clifford his
student.
9. The US Army: ENIAC
Financed by the US army and
developed by scientists John
Presper Eckert & John W. Mauchly,
in 1946, the Electronic Numerical
Integrator and Computer (ENIAC) is
considered to be the first
mainstream digital computer ever
made.
In fact ABC and ENIAC fought a legal
battle till 1973, when ABC was finally
declared to be the 1st digital
computer. ENIAC was mainly built for
US army research laboratory.
10. Gordon Bell and Ken Olson: PDP
(Programmed Data Processor)
They invented the PDP in the year
1960s. Gordon Bell designed the
i/o system of the PDP-1.
Gordon Bell Ken Olson
With time, there have been
several versions of this machine,
i.e., PDP-4, PDP-5, PDP-6,and
PDP-11.
As a part of the DEC (Digital
Equipment Corporation),
Gordon Bell later designed the
VAX, which is DEC's best
computer.
11. What followed in years after 1950 is an
amazing history of computer development.
Further developments in the computer field
led to the invention of transistor (by John
Bardeen, Walter Brattain & Wiliam Shockley
in 1956),
Their invention the transistor,
has been called the most
important invention of the 20th
Century.
12. Integrated circuits (1959) and the computer processors by the iconic Intel.
Then came the brilliant Bill Gates and the legendary Steve Jobs who changed
the computer history.
Bill Gates Who Is The Founder Of
Microsoft
Steve Jobs Who is The Founder of
Apple Inc.
13. Internet history is also an integral
part of the history of computer
development as both can only
coexist. Computer development
saga, in essence, is a magnificent
example of impressive
developments through re-invention,
research, and innovation.
