Computer science is a basic science. It is the science that makes knowledge and its other achievements possible. The study of computer science involves the systematic study of processes (such as coding transformations and algorithms) to help obtain, represent, process, store, communicate, and access information. This is done by analyzing the feasibility, structure, expression, and mechanization of these processes and how they relate to this information. In computer science, the term "information" usually refers to information that is encoded in bits and bytes in a computer's memory.Some higher education institutions may use computer science (CS) as an umbrella term to cover various specialized and professional degrees that include computers and technology. You may also find the term computer science used to refer to information technology (IT) degrees, although many institutions now distinguish between the two (how and where this line is drawn varies).
