Computer science or computing science (sometimes abbreviated CS) is the study of the theoretical foundations of information Information as a concept has many meanings, from everyday usage to technical settings. The concept of information is closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, and representation. In its most restricted technical meaning, information is an and computation Computation is a general term for any type of information processing. This includes phenomena ranging from human thinking to calculations with a more narrow meaning. Computation is a process following a well-defined model that is understood and can be expressed in an algorithm, protocol, network topology, etc. Computation is also a major subject, and of practical techniques for their implementation and application in computer A computer is a machine that manipulates data according to a set of instructions systems.[1][2][3] It is frequently described as the systematic study of algorithmic In mathematics, computing, and related subjects, an algorithm is an effective method for solving a problem using a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields processes that create, describe and transform information. According to Peter J. Denning Peter J. Denning is an American computer scientist, and prolific writer. He is best known for inventing the working-set model for program behavior, which defeated thrashing in operating systems and became the reference standard for all memory management policies. He is also known for his works on principles of operating systems, operational, the fundamental question underlying computer science is, "What can be (efficiently) automated?"[4] Computer science has many sub-fields Computer science has a number of major sub-fields which can be classified by a number of means; some, such as computer graphics Computer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer, emphasize the computation of specific results, while others, such as computational complexity theory Computational complexity theory is a branch of the theory of computation in computer science that focuses on classifying computational problems according to their inherent difficulty. In this context, a computational problem is understood to be a task that is in principle amenable to being solved by a computer. Informally, a computational problem, study the properties of computational problems In theoretical computer science, a computational problem is a mathematical object representing a collection of questions that computers might want to solve. For example, the problem of factoring. Still others focus on the challenges in implementing computations. For example, programming language theory Programming language theory is a branch of computer science that deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features. It falls within the discipline of computer science, both depending on and affecting mathematics, software engineering and linguistics. It is a studies approaches to describing computations, while computer programming Computer programming is the process of writing, testing, debugging/troubleshooting, and maintaining the source code of computer programs. This source code is written in a programming language. The code may be a modification of an existing source or something completely new. The purpose of programming is to create a program that exhibits a certain applies specific programming languages A programming language is an artificial language designed to express computations that can be performed by a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine, to express algorithms precisely, or as a mode of human communication to solve specific computational problems, and human-computer interaction Human–computer interaction is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and focuses on the challenges in making computers and computations useful, usable, and universally accessible to people Humans are bipedal primates belonging to the species Homo sapiens in Hominidae, the great ape family. They are the only surviving members of the genus Homo. Humans have a highly developed brain, capable of abstract reasoning, language, introspection, and problem solving. This mental capability, combined with an erect body carriage that frees the.
The general public sometimes confuses computer science with vocational areas that deal with computers (such as information technology Information technology , as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones.[5]
