# Computer science

**Computer science** (abbreviatit **CS** or **CompSci**) is the scienteefic an practical approach tae computation an its applications. It is the systematic stiddy o the feasibility, structur, expression, an mechanization o the methodical proceedurs (or algorithms) that underlie the acquisition, representacioun, procesin, storage, communicaition o, an access tae information, whethir such information is encodit as bits in a computer memory or transcribit in genes an protein structurs in a biological cell. An alternate, mair succinct definition o computer science is the study o automatin algorithmic processes that scale. A computer scientist specializes in the theorie a computation an the design o computational systems.

Its subfields can be dividit intae a varietie o theoretical an practical disciplines. Some fields, such as computational complexitie theorie (which exploires the fundamental properties o computational an intractable problams), are hielie abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on the challenges in implementin computation. Fer example, programming leid theorie considers various approaches tae the description o computation, while the stiddy o computer programmin itsel investigates various aspects o the use o programmin leid an complex systems. Human–computer interaction considers the challenges in makkin computers an computations usefull, uisable, an universally accessible tae humans.
