How many hours are you work with computer every week? How
many hours are you using computer for entertainment every day? In nineteen-century,
computer was built for simply mathematical computing. No one at that time could
imagine that computer would develop to the greatest manufacture in the science
history; and almost every single person will have at least one. It takes almost
40 year from the first programmable computer appeared to the first personal
computer started to sell. From then on, computer has been experiencing a burst
illuminated explosion development, and occupied people’s life more and more.
As the more and more widely applied of computer, computer
science gradually separated and became a distinct academic discipline. The
first computer science department was founded at the University of Cambridge Computer
Laboratory in 1953. Then more and more universities from all over the world
started to set computer science department. As a discipline, computer science
spans a range of topics from theoretical studies of algorithms and the limits
of computation to the practical issues of implementing computing systems in
hardware and software. [1] The IEEE Computer Society (IEEE-CS) identifies four
areas that it considers crucial to the discipline of computer science: theory
of computation, algorithms and data structures, programming methodology and
languages, and computer elements and architecture. [2]
