This portal is for the academic discipline of computing science. For other related portals such as computer networking, computer security and information technology, please see portals: technology and applied sciences. edit  The Computing Science Portal Computer science is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Computing science encompasses many branches; some emphasize the computation of specific results (such as computer graphics), while others (such as computational complexity theory) relate to properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing a computation, while computer programming applies specific programming languages to craft a solution to some concrete computational problems. More on computing science... edit  Selected quote “ ...the unfactored criterion "A program is good (enough) as long as it satisfies your customers." is too woolly to be of any help. ” — Edsger W. Dijkstra (1930-2002) [EWD603: Tripreport, E.W.Dijkstra Archive] edit  Featured article Fortran (previously FORTRAN) is a general-purpose, procedural, imperative programming language that is especially suited to numeric computation and scientific computing. Originally developed by IBM at their campus in south San Jose, California in the 1950s for scientific and engineering applications, Fortran came to dominate this area of programming early on and has been in continual use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics and computational chemistry. It is one of the most popular languages in the area of high-performance computing and is the language used for programs that benchmark and rank the world's fastest supercomputers. edit  Selected picture Partial map of the Internet based on the January 15, 2005 data found on opte.org . Each line is drawn between two nodes, representing two IP addresses. The length of the lines are indicative of the delay between those two nodes. This graph represents less than 30% of the Class C networks reachable by the data collection program in early 2005. Lines are color-coded according to their corresponding RFC 1918. edit  Related portals Artificial intelligence Information technology Software Free software Linux Computer programming Java Python programming edit  Selected biography Frances Elizabeth "Fran" Allen b. 1932 Fran Allen is an American computing scientist and pioneer in the field of optimizing compilers. Her achievements include seminal work in compilers, code optimization, and parallelization. She also had a role in intelligence work on programming languages and security codes for the National Security Agency. Allen is a fellow of the IEEE, the Association for Computing Machinery (ACM) and the Computer History Museum. She is currently on the Computer Science and Telecommunications Board, the Computer Research Associates (CRA) board and National Science Foundation's CISE Advisory Board. She is a member of the National Academy of Engineering, the American Academy of Arts and Sciences and the American Philosophical Society. In 1997, Allen was inducted into the WITI Hall of Fame. She retired from IBM in 2002 and won the Augusta Ada Lovelace Award that year from the Association for Women in Computing. In 2007 Allen was recognized for her work in high performance computing when she received the A.M. Turing Award for 2006. She became the first woman recipient in the forty year history of the award which is considered the Nobel Prize for computing and is given by the Association for Computing Machinery. In interviews following the award she hoped it would give more "opportunities for women in science, computing and engineering". In 2009 she was awarded an honorary doctor of science degree from McGill university for "pioneering contributions to the theory and practice of optimizing compiler techniques that laid the foundation for modern optimizing compilers and automatic parallel execution". edit  Computer science topics Taxonomic classification ACM Computing Classification System Outline of computer science Theory Ackermann function Automata theory Computational complexity theory Algorithms Binary search Brute-force search Divide and conquer Dynamic programming Greedy Recursive descent Regular expressions Data structures Array Linked list Binary tree Heap Hash table Adjacency list Applied fields Artificial intelligence Bioinformatics Computational linguistics Computer graphics Computer networking Relational databases Information retrieval Numerical analysis Miscellaneous computing Distributed computing Parallel computing Real-time computing Quantum computer DNA computing Hardware Central processing unit Computer architecture CPU cache Floating point arithmetic Computer storage History of computing hardware Operating systems Windows NT group BeOS BSD Haiku Lisp machine Linux kernel Unix OpenVMS Data languages HTML XML MediaWiki SQL MDX Scripting languages AppleScript DCL JavaScript JCL PHP TECO Unix shell Csh Windows PowerShell Programming languages Ada ALGOL BASIC C C++ C# Dylan Eiffel Erlang Forth Fortran Haskell Java JavaScript Lisp Objective-C OCaml Perl PHP PL/I Prolog Python R Ruby Scala Scheme Programming paradigms Functional programming Imperative programming Literate programming Logic programming Object-oriented programming Structured programming Computer scientists Kent Beck Ward Cunningham Edsger Dijkstra Jean Ichbiah Gary Kildall Donald Knuth Marvin Minsky Linus Torvalds Alan Turing Niklaus Wirth Other History of computer science edit  Categories Algebra Algorithms Artificial intelligence Awards Competitions Compiler construction Computational science Computer engineering Computer programming Computing science Computing scientists Computer vision Concurrency Conferences Cryptography Education Human–computer interaction Information science Literature Machine learning Optimization edit  Related WikiProjects Computer science C++ Computational biology Computer vision Computing Cryptography Databases Java Logic Mathematics Software edit  Things you can do Copyedit: Computing Expand: Computer science, Computer science stubs, Computer science articles needing expert attention Create new articles - Requested articles edit  Associated Wikimedia Directory of pages for Portal:Computing_science What are portals?
