History of computer science

Computer is generally defined as the study of both the computing, hardware (hardware) and software (the software). Computer science includes a variety of topics relating to computers, ranging from the abstract analysis of algorithms to more concrete subjects like programming languages, software, including hardware. As a discipline, Computer Science is more emphasis on computer programming, and software engineering (software), while the computer technique is more likely related to things like computer hardware (hardware). However, both terms are widely misunderstood by many people.

Church-Turing thesis states that all computing devices that have been commonly known fact the same in terms of what they can do, though with different efficiency. This thesis is sometimes regarded as the basic principles of computer science. Computer scientists usually emphasizes von Neumann computers or Turing machines (computers that do small tasks and deterministic at a certain time), because things like that most computers in use today. Computer scientists are also studying other types of machines, some of which can not be of practical use (such as neural computers, DNA computers, and quantum computers) and some are still quite theoretical (such as computers and computer random oracle).

Computer Science learn what can be done by several programs, and what is not (komputabilitas and artificial intelligence), how the program should evaluate the outcome (algorithm), how the program should store and retrieve bits of an information (data structures), and how to program and communicate the user (the user interface and programming language).

Computer science is rooted in electronics, mathematics and linguistics. In the last three decades of the 20th century, computer science has become a new discipline and has developed his own methods and terminology.

The first computer science department at Purdue University was founded in 1962. Almost all universities now have the computer science department.

The highest award in computer science is the Turing Award, the winner of this award are all pioneers in their fields.

Edsger Dijkstra said:

Computer science is not about computers as astronomy is not about the telescope

Renowned physicist Richard Feynman said:

Computer science is not as old as the age of physics; younger than a few hundred years. However, this does not mean that the "meal" computer scientist is much less than physicists. It is younger, but grew up in a much more intense!
