TEXT 1
THE TERM OF COMPUTER ARCHITECTURE
In computer science and engineering, computer architecture is
the art that specifies the relations and part of a computer system. In
the architecture of buildings, this art is normally visual, but computer
architecture is logical, defining systems to serve particular purposes.
In both instances (building and computer), a complete design has
many details, and some details are implied by common practice.
For example, at a high level, computer architecture is
concerned with how the central processing unit (CPU) acts and how
it uses computer memory. Some fashionable computer architectures
include cluster computing and Non-Uniform Memory Access.
The first documented computer architecture was in the
correspondence between Charles Babbage and Ada Lovelace,
describing the analytical engine. Another early example was John
Von Neumann's 1945 paper, First Draft of a Report on the EDVAC,
which described an organization of logical elements. IBM used this
to develop the IBM 701, the company's first commercial stored
program computer, delivered in early 1952.
