According to the Encyclopedia Britannica,
"Computer Science is the study of computers: namely, their design (architecture) and their uses for computations, data processing, and systems control. Computer science includes engineering activities such as the design of computes and of the hardware and software that make up computer systems. The field also encompasses theoretical, mathematical activities, such as the design and analysis of algorithms, performance studies of systems and their components by means of techniques like queuing theory, and the estimation of the reliability and availability of systems by probabilistic techniques as a discipline that involves the understanding and design of computers and computational process."
COMPUTER SCIENCE plays a major function in today's world. A lot of what you will learn in your Computer Science courses will be useful and can be applied to your everyday living.
