A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. Computer software, or simply software, is a generic term that refers to a collection of data or computer instructions that tell the computer how to work, in contrast to the physical hardware from which the system is built, that actually performs the work. Software engineering is the application of engineering to the development of software in a systematic method. Alan Mathison Turing OBE FRS was an English computer scientist, mathematician, logician, cryptanalyst, philosopher, and theoretical biologist. Moore's law is the observation that the number of transistors in a dense integrated circuit doubles about every two years.
