Computer architecture, in general, refers to the rules and procedures that specify the functions, capabilities, programming model, and implementation of a computer system. Computer Organization, on the other hand, is the interactive interaction of hardware programs and users. The study of Computer Architecture and Computer Organization enables one to understand the execution of computer instructions at the micro level, allowing one to build programs that are quicker, smaller, and less prone to mistakes. It provides information regarding the relative cost of computer operation, the relationship between software and users, and the inner workings of computers.
