The defining feature of recent computers which distinguishes them from all other machines is that they can be programmed That is to say that some type of directions (this system ) might be given to the computer, and it will process them. Modern computers based mostly on the von Neumann structure often have machine code within the form of an imperative programming language In sensible terms, a computer program may be only a few instructions or prolong to many tens of millions of directions, as do the applications for word processors and net browsers for instance. A typical modern computer can execute billions of instructions per second ( gigaflops ) and infrequently makes a mistake over many years of operation. Large computer applications consisting of a number of million instructions may take teams of programmers years to write, and as a result of complexity of the duty virtually actually include errors.

Fashionable computers inherently follow the ideas of the stored program laid out by John von Neumann in 1945. Primarily, the program is read by the computer one instruction at a time, an operation is performed, and the computer then reads the subsequent instruction.
