The Microprocessor and Microcomputer
The microprocessor is a digital integrated circuit device that can be programmed with a series of instructions to perform specified functions on data. When a microprocessor is connected to write an essay, a memory device and provided with a means of transferring data to and from the "outside world,"you have a microcomputer.
