What is About computer History Or Computer Science History
The Question of What is Computer Science History is not the
limited or descriptive subject. This History of Computer starts before the 20th
century and emerged in the 20th century. The Mechanical inventions and the
mathematical theories progressed in this century. So this Modern Computer
concepts and advanced machines for this invented in this century.
What is the Earlier
History of Computer Science?
First Computer tool or machine invented in the 2700 – 2300 BCE
with the name ABACUS. Yes we can say the ABACUS is the First Computer
developed. Abacus contained the successive columns table which has the managed
successive orders of its magnitude for its sexagesimal system of number. The
Actual or real use style of this abacus was the drawn lines with the help of
pebbles in the sand.
Next To calculate the astronomical positions The ‘Antikythera
Mechanism’ has been developed earliest. This is also called the First Mechanical
Analog computer. It has been discovered in the 1901 on the Greek island of
Antikythera. This is also called the between of Kythera and the Crete, Dateted
was to 100 BCE.

Early of 17th Century it has been discovered the logarithms for the purpose of
computational by the John Napier. Then Calculating Machine
has been desired in 1623 by the Wilhelm Schickard but this effort had
destroyed in 1624 by Fire. Then in 1640, A French Mathematician Blaise
Pascal constructed the First Mechanical adding device. Next By Gottfried
Wilhelm Leibnitz the Stepped Reckoner has been invented in the 1672 and this
has been completed in the 1694.
First Analytical
Engine has been described in the 1837
by the Charles Babbage. And this is
also called the First Modern Computer. That analytical engine had contained the
Memory for expandable, Arithmetic Unit,
and the Logic for processing the abilities capable to interpret the programming
language with the conditional branching and loops.
Binary Logic For
Computer: Gottfried Wilhelm Leibnitz
programmed the formal, mathematical sense logic with his writings on the system
of binary numeral in 1703. Binary code only represents the o and 1 numbers,
Here o stands for False and 1 Stands for True always. Boolean algebra published
in the 1854 with the complete system that allowed the processes of
computational in the model of mathematically.
Till That time, First Mechanical Device running on binary
pattern had been invented and that was the industrial revolution.
The Birth of Computer:
Before 1920 the human were performed the computations for all clerical works.
Then after thousands of computer employed in the commerce,
Government and the research establishments.
Mostly these computer work performed by the women.
So after the 1920s the First computer machine for expression
referred to any machine that performed the work of any human computer.
After that The Digital Machinery invented in the contrast to
analog, that were able to render the state of the value of numeric and save
each digit individually. This digital
Machinery used the difference engines or the relays before the inventions of
faster the devices memory.
Beyond the 1990s,
1.
Parallel computers developed continuesouly.
2.
Biological Computing invented to calculate the
DNA under the Human Genome Project.
3.
Then Quantum Computing boost the discovery of
Computer History.
4.
The Links “Information Superhighway” Link more
and more for worldwide computers.
5.
In Sizes Computers get smaller to smaller,
finally it birth the nano – technology.
