The above story is that the computer was invented
Before 1920, the term computer Habal of a human being who performed calculations

The first investigators on the issue of Computed

• wanted to know what things can be computed by a man (according to a list of written instructions) l, without knowing the problem in the past for as long as necessary

decade in 1940 while performing computers, the term began to use computers for machines instead of people.
The field of computer science was expanded while it looked provider can do more things that mathematical calculations to study computer science) in the general .

• Java Enterprise Edition or J2EE is the
  platform for running applications
  business written in Java .

Computer science is the study of the theoretical foundations of information and computing in addition to its practical application in computer systems. (Wikipedia )

Diferenctes fields of study :

• Specific results of the computation ( by computer ),
• graphic example of the complexity theory )
• computational problems that require the implementation of computations .
