the study of automating algorithmic processes that scale. A computer
scientist specializes in the theory of computation and the design of computational

fields, such as computational complexity theory (which explores the fundamental
focus on challenges in implementing computation. For example, programming language
of computer programming itself investigates various aspects of the use of programming
language and complex systems. Humancomputer interaction considers the challenges
in making computers and computations useful, usable, and universally
accessible to humans.
