Introduction to Microprocessor:
Microprocessor works like a CPU in a microcomputer. It's present as a single IC chip in a microcomputer. Microprocessor is the soul of the machine.
A Microprocessor is a device, which is able to
The device that performs tasks is known Arithmetic Logic Unit (ALU). A single chip called Microprocessor performs these all tasks together with other tasks.
A MICROPROCESSOR is versatile programmable logic device that reads binary instructions from a storage device known memory accepts binary data as input and processes data according to those instructions and give results as input.
Figure explained a programmable machine, which consists of a microprocessor, I/O, memory. These all 3 components work together to perform a given task.
