The role of an operating system (OS) is to manage the complexity of various components, that a computer is composed of, and to present a simplified programming interface to the application programmer.
Those much-cited computer models are composed of numerous simulations that individually account for naturally occurring variability.
This is accomplished by first generating or initializing a population of random computer programs that are composed of the basic building blocks needed to solve or approximate a solution to the problem.
Urban factories and industrial parks, apparently seen from the vantage of aerial surveillance, are composed of computer parts and electronic odds and ends.
In order to implement the null test of aspheric surfaces as simply as that of spherical ones in a commercial digital phase-shift interferometer, computer generated holograms (CGHs) that are composed of a main CGH, which produces the ideal aspheric wavefront, and an alignment CGH, which aids in calibration, were utilized.
Mechatronic systems are fully-integrated engineering systems that are composed of mechanical, electronic, and computer control sub-systems.
These models are composed of several hundred thousand lines of computer code that divide the air, land and oceans into a grid of hundreds of interacting boxes.
It found that the Pentagon's computer networks had been "built on inherently insecure architectures that are composed of, and increasingly using, foreign parts".
Indeed, they are composed of a large number of various kinds of components (mechanical, electrical, computer, etc).
