Pangwanoh

Pikeun kaperluan praktis, élmu komputer kaasup ogé topik-topik anu aya hubunganana jeung komputer, tina hal saperti analisa algoritma abstrak, formal grammars, jeung salian ti eta, nepi ka subyék anu kongkrit saperti programming language, software, jeung hardware komputer. Sabagé disiplin élmu, loba bédana jeung matematik, programming, rékayasa software, sarta rékayasa komputer, sanajan kadang-kadang ngabingungkeun. Edsger Dijkstra nyebutkeun yén:
"Computer science is no more about computers than astronomy is about telescopes."
Dilengkepan ku physicist Richard Feynman nyebutkeun:
"Computer science is not as old as physics; it lags by a couple of hundred years. However, this does not mean that there is significantly less on the computer scientist's plate than on the physicist's: younger it may be, but it has had a far more intense upbringing!"

Tesis Church-Turing thesis nyebutkeun yén sakabéh tipe paradigma kanyaho anu reasonable tina komputasi mangrupa hal anu sarua pentingnya salila bisa ngagawekeun sanajan aya variasi efisien dina waktu jeung ruang. Tesis ieu lain téorema matematika anu bisa dibuktikeun, tapi a statement based on empirical observation that two distinct computational schemes do in fact have the same computational power. This thesis is a fundamental principle of computer science.

Most reséarch in computer science has been related to von Neumann computers or Turing machines (computers that do one small, deterministic task at a time). These modéls resemble most réal computers in use today. Computer scientists also study other kinds of machines, some practical (like parallel machines) and some théoretical (like random, oracle, and  quantum machines).

Computer scientists study what programs can and cannot do (see computability and artificial intelligence), how programs should efficiently perform specific tasks (see algoritma), how programs should store and retrieve specific kinds of information (see data structures and data bases), and how programs and péople should communicate with éach other (see human-computer interaction and user interfaces).

Computer science has roots in electrical engineering, mathematics and  linguistics. In the last third of the 20th century computer science has become recognized as a distinct discipline and has developed its own methods and terminology.

The first computer science department in the United States was founded at Purdue University in 1962. The University of Cambridge in England, among others, taught CS prior to this, however at the time, CS was seen as a branch of mathematics, and not a separate department. Cambridge claims to have the world's oldest taught qualification in computing. Most universities today have specific departments devoted to computer science.

The highest honor in computer science is the Turing Award.

 Prominent pioneers in computer science 
 Charles Babbage, Designed and built a prototype for a mechanical calculator; designed, but never built, the more powerful Analytical Engine.
 John Backus Invention of FORTRAN (Formula Translation), the first practical high-level programming language and the Backus-Naur form for describing formal language syntax.
 James W. Cooley and John W. Tukey The Fast Fourier Transform and its impact on scientific reséarch. 
 Ole-Johan Dahl and Kristen Nygaard, inventors of the proto-object oriented language SIMULA.
 Edsger Dijkstra for algorithms, Goto considered harmful, rigor, and pedagogy.
 C.A.R Hoare for the development of the formal language Communicating Sequential Processes (CSP) and Quicksort.
 Admiral Grace Murray Hopper, for doing pioneer work in the 1940s, one of the first to recognize the necessity for higher level programming languages, or what she termed automatic programming. She wrote the A-O compiler. Her idéas héavily influenced the COBOL language.
 Kenneth Iverson Inventor of APL, for his contribution to interactive computing. 
 William Kahan for the IEEE floating-point standard. (Perhaps this reference should be moved to hardware engineering.)
 Donald Knuth for The Art of Computer Programming series.
 Ada Lovelace, contemporary of Charles Babbage, famous for her Sketch of the Analytical Engine, an analysis of Babbage's work; the namesake for the modérn computer language, Ada.
 John von Neumann for devising the von Neumann architecture upon which most modérn computers are based.
 Claude E. Shannon for information theory.
 Alan Turing for computability theory, pioneering work in the field of Artificial Intelligence, and for the design of the Pilot ACE.
 Maurice Wilkes for building the first practical stored program computer to be completed, and credited with the idéas of several high-level programming language constructs.
 James H. Wilkinson The technique of "backward error analysis" and advances in the field of matrix computations. Wilkinson was also a principal mover in the development of the Pilot ACE, the first British computer, in the late 1940s. (See more on Wilkinson in the MacTutor Biographies.)
 Konrad Zuse Builder of a binary computer in the 1930s, for which he allegedly devised a théoretical high level programming language, Plankalkül.
