Basic Computer Organization
Even though the size, shape, performance, reliability, and cost of computers have been
changing over the years, the basic logical structure (based on stored program concept) as
proposed by Von Neumann has not changed. No matter what shape and size of computers
we are talking about, all computer systems perform the following five basic operations
for converting raw input data into information useful to their users:
1. Inputting. The process of entering data and instructions into the computer system. 2. Storing. Saving data and instructions so that they are available for initial or for
