A computer system is a digital electronic machine that can programmed to perform some operations as per the computer program instructions. A computer therefore, is a collection of electronic parts (body) with a set of instructions controlling it (mind). Introduction to Computing The electronic computer is one of the most important developments of the twentieth century. User cannot execute privileged instructions; the user must ask, switches back to user mode, and gives control bac.
