First and Second Grade

1. Computer History

2. The ABACO
Would Be 5000
years old.
It is the first tool
to calculate known

3. Blaise Pascal (1623-1662)
French mathematician.
Built the first machine of Sums in 1642

4. Howard Aiken
American physicist and
mathematician applied.
Built the Harvard Mark I in
collaboration with IBM in
1944.
Numbers of 23 digits,
logarithms and
trigonometric functions

5. First Generation - 1940-1956: Vacuum Tubes
ENIAC: Electronic Numerical Integrator And
Calculator.
Created in 1946 First electronic digital computer
general purpose.
Use 19000 vacuum tubes filling a room 30x50 feet,
weight 30 tons.

6. Generation - 1956-1963: TransistorsSecond
The first computers of this generation were
developed for the atomic energy industry.

7. Third Generation - 1964-1971: Integrated Circuits
Computers for the first time
became accessible to a mass
audience because they were
smaller and cheaper than their
predecessors.

8. Fourth Generation - 1971-Present: Microprocessors
The microprocessor brought the
fourth generation of computers,
as thousands of integrated
circuits we rebuilt onto a single
silicon chip.

9. Fifth Generation - Present and Beyond:
Artificial Intelligence
Fifth generation computing devices, based on
artificial intelligence, are still in development,
though there are some applications, such as
voice recognition, that are being used today.

10. The future...?
In the future computers will be capable of integrating
with our brain, so real or virtual., such as Johnny
Mnemonic, and running platforms so similar to our
daily lives that we won't know distinguish between
reality and virtuality.
