What is Computer Science
Machine for calculating task have existed since antiquity. The ancient Sanskrit treatise " Rules of Chord" the algorithms book written in 800 BC for constructing geometrical objects such as altars using a chord and peg.
"Pascal's Calculator" designed and constructed by Blaise Pascal in 1642.
Stepped Reckoner developed by the Gottfried Leibniz in 1673. Gottfried Leibniz may be considered the first information theorist and scientist of the computer and developer because he documenting the number of binary systems.
The Mechanical calculator industry launched by Thomas De Colmar in 1820, which was first calculating strong enough machine at the present time.
Charles Babbage with his Difference Engine, he started the design of first automatic machine calculator in 1822 and gave him an idea of first programmable machine calculator, his Analytic Engine. In 1834, he started to developing this machine, in less than 2 years, he sketched out several salient features of the modern computer. Charles Babbage credited with the inventing the first mechanical computer. In 1843, Jacquard Loom adopted crucial step of a punched card system and making it infinitely programmable .
Ada Lovelace wrote the first algorithm intended for the processing of computer system. She included an algorithm to the computer the Bernoulli Numbers. Herman Hollerith invented the first Tabulator and eventually his company become the part of IBM. Howard Aiken convinced IBM, one hundred years after in 1937. The new and more powerful computer developed during 1940.
By the passage of time, it became clear that computer could be used for many other problems than Mathematical Calculation. In 1950, Computer science established academic discipline.
The relationship between a software engineer and computer is a contentious issue. David Parnas claimed the principal focus of computer science by taking the cue from the relationship between science discipline and other engineers.
Computer science is not just about writing computer programs or building a phenomenon computer. Many students choose the computer science for different reasons because it is very easy to use if they concentrate and they want to become the software engineer in future and they want to make their career best. Computer science is used to solve our common and daily life problems. Generally, computer science is the study of computer technology, both software, software but we can see.The physical part of a computer that can we see and touch is called hardware. Software can't be executed without hardware and hardware can't perform any function without software.
