MICROPROCESSOR:
A
microprocessor consists of multiple independent function units. The memory
interface fetches instructions from, and writes data to, external memory. The
control unit issues one or more instructions to other function units. These
units process the instructions in parallel to boost performance.
A microprocessor consists of
multiple internal function units. A basic design has an arithmetic logic unit
(ALU), a control unit, a memory interface, an interrupt or exception
controller, and an internal cache. More sophisticated microprocessors might
also contain extra units that assist in floating-point match calculations,
program branching, or vector processing .

MICRO COMPUTER:
A microcomputer is a
computer with a microprocessor as its central processing unit. It includes a
microprocessor, memory, and input/output (I/O) facilities. Such computers are
physically small compared to mainframes and minicomputers. Many microcomputers
(when equipped with a keyboard and screen for input and output) are also
personal computers
The term microcomputer
is generally synonymous with personal computer (PC), or a computer that depends
on a microprocessor. Microcomputers are designed to be used by individuals,
whether in the form of PCs, workstations or notebook computers. A microcomputer
contains a central processing unit (CPU) on a microchip (the microprocessor), a
memory system (typically read-only memory and random access memory), a bus
system and I/O ports, typically housed in a motherboard.
