Computer architecture, or digital computer organization, is the conceptual design and fundamental operational structure of a computer system. It focuses largely on the way by which the central processing unit performs internally and accesses addresses in memory.<ref>{{cite web|last=A. Thisted|first=Ronald|title=Computer Architecture |url=http://galton.uchicago.edu/~thisted/Distribute/comparch.pdf|publisher=The University of Chicago|date=April 7, 1997}}</ref> Computer engineers study [[computational logic]] and design of [[computer hardware]], from individual [[Processor (computing)|processor]] components, [[microcontroller]]s, [[personal computer]]s to [[supercomputer]]s and [[embedded system]]s. The term “architecture” in computer literature can be traced to the work of Lyle R. Johnson and [[Fred Brooks|Frederick P. Brooks, Jr.]], members of the Machine Organization department in IBM's main research center in 1959. | |||
