Set r to be the remainder obtained from the integer division of a and b.Ĭonsider computing the GCD of 42 and 30. If b is zero, then the GCD of a and b is a. The algorithm given below can be used to compute the GCD of two positive integers a and b: In case you’ve forgotten, the GCD of two positive integers is the greatest integer that is an even divisor of both numbers.

If you have ever followed a recipe when cooking, followed a set of driving directions, or filled out an income tax form, you have worked with an algorithm.įor example, at some point in time you were probably taught how to determine the greatest common divisor (GCD) of two numbers. Computer science combines the theoretical concepts of algorithm design and analysis with the practical considerations of how to implement algorithms on a computer and solve practical problems.Īn algorithm defines a detailed and unambiguous sequence of actions for solving a particular problem or for performing some task.

Algorithms, in one form or another, are central to computer science.

An example, which we will discuss later, is the discovery that some important problems simply cannot be solved by computation.ĭespite many variations, essentially all definitions of computer science emphasize the study of algorithms. On the other hand, computer scientists do use the scientific method to propose and test hypotheses, and some very nonobvious discoveries in computer science have important real-world implications. Some argue that computer science is really computer art (where art means practice). In that sense, computer science is more like mathematics than science. It’s also a fair question to ask, How is computer science a science? In contrast to physics, biology, and chemistry, computer science is not based on the study of the natural world. 3, March 1986) emphasizes algorithm development and analysis as the central focus of computer science.

It says that computer science is the study of computers and algorithmic processes, including their principles, their hardware and software design, their applications, and their impact on society.Ī famous definition of computer science by Gibbs and Tucker (Gibbs and Tucker, A Model Curriculum for a Liberal Arts Degree in Computer Science, Comm. ()Īnother broad definition comes from the Association for Computing Machinery (ACM) Model Curriculum.

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. The systematic study of computing systems and computation. The US National Coordination Office for Networking and Information Technology Research and Development (NITRD) defines computer science in a similarly broad way: Wikipedia (en./wiki/Computer_science) defines computer science as the collection of a variety of disciplines related to computing, both theoretical and practical: theoretical foundations of information and computation, language theory, algorithm analysis and development, implementation of computing systems, computer graphics, databases, data communications, etc. Introduction to Computer Science WHAT IS COMPUTER SCIENCE?Ĭomputer Science is defined in different ways by different authors.
