Unit II: Basic Organization of Computer | BCA 1st Semester Computer Fundamentals and Application Notes Pdf

Even though the size, shape, performance, reliability, and cost of computers have been changing over the years, the basic logical structure (based on the stored-program concept), as proposed by John Von Neumann, has not changed. No matter what shape and size of a computer we are talking about, all computer systems perform the following four basic operations for converting raw input data into useful information and presenting it to a user:

A computer's components or devices are used to do these tasks. Typically, computer components are only built to execute one of these four purposes. Some specialized components or gadgets, on the other hand, are intended to accomplish two, three, or even all four roles. A hard drive, for example, may fulfill three functions: input (when data are read), storage (when files are saved), and output (when files are written) (when files are written).
