COMPUTER ARCHITECTURE

computer architecture, structure of a digital computer, encompassing the design and layout of its instruction set and storage registers. The architecture of a computer is chosen with regard to the types of programs that will be run on it (business, scientific, general-purpose, etc.). Its principal components or subsystems, each of which could be said to have an architecture of its own, are input/output, storage, communication, control, and processing.

In computer engineering, computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. The architecture of a system refers to its structure in terms of separately specified components of that system and their interrelationships

This form of computer architecture is known as a Von Neumann machine, named after John Von Neumann, one of the originators of the concept. With very few exceptions, nearly all modern computers follow this form. Von Neumann computers are what can be termed control-flow computers. The steps taken by the computer are governed by the sequential control of a program. In other words, the computer follows a step-by-step program that governs its operation
