All About Computer science
Computer science is the scientific and practical approach to computation and its applications
It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information, whether such information is encoded as bits in a computer memory or transcribed in genes and protein structures in a biological cell
A computer scientist specializes in the theory of computation and the design of computational systems.
Its subfields can be divided into a variety of theoretical and practical disciplines
Some fields, such as computational complexity theory (which explores the fundamental properties of Computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications
Still other fields focus on the challenges in implementing computation
For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems
Human-computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.
Computer science deals with the theoretical foundations of information and computation, together with practical techniques for the implementation and application of these foundations
