Computer Science

A.   Computer Science

Computer science, in general, is interpreted as a study of both computing, hardware and software. Computer science covers a variety of topics related to computers, ranging from abstract analysis of algorithms to more concrete subjects such as programming languages, software, including hardware. As a scientific discipline, Computer Science places more emphasis on computer programming, and software engineering (software), while computer engineering is more likely to be related to things like computer hardware (hardware). However, both terms are often misunderstood by many people.

Church-Turing's thesis states that all computing devices that are commonly known are actually the same in terms of what they can do, even with different efficiency. This thesis is sometimes considered the basic principle of computer science. Computer scientists usually emphasize von Neumann computers or Turing machines (computers that do small, deterministic tasks at a given time), because that's how most computers are used today. Computer science experts also study other types of machines, some of which cannot be used practically (such as neural computers, DNA computers, and quantum computers) and some of them are still quite theoretical (such as random computers and oracle computers).

Computer Science learns what some programs can do, and what doesn't (computability and artificial intelligence), how the program must evaluate an outcome (algorithm), how programs must store and retrieve certain bits of information (data structures), and how programs and users communicate (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 scientific discipline and has developed its own methods and terms.

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

The highest award in computer science is the Turing Award, the winners of this award are all pioneers in their fields. Edsger Dijkstra said: “Computer science is not about computers as astronomy is not about telescopes”

Renowned physicist Richard Feynman said: “Computer science is not as old as physics; a few hundred years younger. However, this does not mean that "dishes" of computer scientists are far less than physicists. Actually it's younger, but grow up intesively!”

B.   Computer structure

The structure of a computer system can be divided into:

1.      Computer Operating System.

2.      I / O structure.

3.      Storage Structure.

4.      Storage Hierarchy.

5.      Hardware Protection

C.  Benefits of computers

1.      Field of education

2.      Industrial and manufacturing fields

3.      Field of Engineering and Science

4.      Field of aviation

5.      Field of medicine

6.      Field of crime

7.      Field of Intertaintment and games

8.      Global network communication field (internet)

9.      Field of government
