The basic blocks of a computer are CPU (Central Processing Unit) or Processor, Memory and I/O (Input-Output) device.
Due to advances in semiconductor technology, it is possible to fabricate the CPU on one or more than one chips. The result is the microprocessor. Both MOS (Metal Oxide Semiconductor) and Bipolar technologies can be used in this fabrication process. The CPU can be placed on a single chip when MOS technology is used. When Bipolar Technology is used, then a number of chips are required.
Microprocessor is the CPU of the Microcomputer.
Microcomputer consists of microprocessor as CPU, memory and I/O (Input-Output) device.
Microprocessor contains ALU (Arithmetic and Logic Unit), Control Unit and several registers.
ALU (Arithmetic and Logic Unit) is a digital circuit that performs arithmetic and logical operations on two n-bit digital words.
Note: The size of ALU defines the size of microprocessor.
Example: Motorola 68000 is a 16-bit microprocessor because its ALU is 16 bits wide.
