====Computer architecture and microarchitecture====

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.

The term "architecture" in computer literature can be traced to the work of Lyle R. Johnson and [[Frederick P. Brooks Jr.]], members of the Machine Organization department in IBM's main research center in 1959.
