Computer science is the scientific and practical approach to computation and its applications. The systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) underlies information acquisition, representation, processing, storage, and communication in computer systems. An important field related to computer science is information theory which studies quantitative aspects of information, especially communication channels and data compression.
Computer science includes many sub-fields, such as Artificial Intelligence (AI), graphics or image processing, DataBase Management Systems (DBMS), networks & security system design, etc. The interdisciplinary nature of CS also gives rise to fields like Computational Linguistics (CL) & Natural Language Processing (NLP). A.I. makes computers behave like humans while carrying out tasks such as reasoning & problem-solving. In contrast, CL deals with understanding human languages by computers so that they can respond as humans expect them to. DBMS involves developing database management software, while graphic or image processing involves manipulating digital images using algorithms.
