Computer science is the study of the storage, transformation and transfer of information. The field encompasses both the theoretical study of algorithms
(including their design, efficiency and application) and the practical problems involved in implementing them in terms of computer software and hardware.
Computer science has its roots primarily in the fields of electrical engineering
(i.e., electronics), mathematics
. It is still a relatively young field, mainly because it was only about a half century ago that electronics technology became sufficiently advanced to allow the construction of even primitive electronic computing devices.
In computer science, scientists apply concepts and techniques of computation, algorithms and computer design to a specific problem.
