It has been estimated that there were only about 100 hand-built computers in the world in 1953. Researchers such as Tom Kilburn at the University of Manchester completed a device called MEG, which did floating-point calculations. This machine evolved into the first transistorized computer, the Metro-Vickers MV950, leading to mass production of computers.*Alan Turing published an article describing the first 1,104 zeroes of the Riemann zeta-function, culminating 15 years of work on how to use computers to tackle a fundamental problem in number theory.

The study of computer hardware and software.

n.: A science whose goal is to build something that will lasts at least until they've finished building it.

(ISO) The branch of science and technology that is concerned with methods and techniques relating to data processing performed by automatic means.

the study of algorithms, including their formal and mathematical properties, hardware realizations, linguistic realizations, and applications; the science of algorithmic problem solving

the branch of engineering science that studies (with the aid of computers) computable processes and structures

( CS): Programs that stress the theoretical side of programming, with emphasis on systems programming versus applications programming. Also called software engineering (SE) programs. 16.13 Computer science education, 16.12 Computer science engineer/software engineer, 16.9

programming: A collective term for the mathematical and theoretical underpinnings of computers and computing.

The systematic study of computing systems and computation. The body of knowledge resulting from this discipline contains theories for understanding computing systems and methods; design methodology, algorithms, and tools; methods for the testing of concepts; methods of analysis and verification; and knowledge representation and implementation.

Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems."Computer science is the study of information" http://www.njit.edu/v2/archivecatalog/undergraduate/91/19-und.html Department of Computer and Information Science, Guttenberg Information Technologies"Computer science is the study of computation." http://www.csbsju.edu/computerscience/curriculum Computer Science Department, College of Saint Benedict, Saint John's University"Computer Science is the study of all aspects of computer systems, from the theoretical foundations to the very practical aspects of managing large software projects." http://study.massey.ac.nz/major.asp?major_code=2010&prog_code=93068 Massey University Computer science has many sub-fields; 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 computations, while computer programming applies specific programming languages to solve specific computational problems with solutions.

Computer Science is a timed computer science test given at UIL and TMSCA academic competitions. For UIL competitions, the test consists of two parts: an individually taken multiple-choice test and a team hands-on programming test. At the district level, only the multiple-choice test is administered.
