There are three different categories for computer architecture: System design, instruction set architecture (ISA), and Microarchitecture. There are also four main components such as, structure, organization, implementation, and performance. And the most popular type of computer architecture is Von Neumann Architecture which was started in 1945 by the mathematician Jon Von Neumann. Many modern computer companies work on various projects involving computer architecture today. 11/4/2014 Computer Architecture 19 Questions • Name one of the four main components in computer architecture.
