The history of computer science began long before the modern discipline of computer science, usually appearing in forms like mathematics or physics. Developments in previous centuries alluded to the discipline that we now know as computer science. [ 1 ]
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
The term virus was first used as a technical computer science term by Fred Cohen in his 1984 paper "Computer Viruses Theory and Experiments", where he credits Len Adleman with coining it. Although Cohen's use of virus may have been the first academic use, it had been in the common parlance long before that.
Computer science is more theoretical (Turing's essay is an example of computer science), whereas software engineering is focused on more practical concerns. However, prior to 1946, software as we now understand it – programs stored in the memory of stored-program digital computers – did not yet exist.

A model always is a model of something—it is an image or representation of some natural or artificial, existing or imagined original, [11] where this original itself could be a model. 2. Reduction In general, a model will not include all attributes that describe the original but only those that appear relevant to the model's creator or user. 3.
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).

A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
