2. What is a Microprocessor ?
• Multi programmable device
• Incorporates with Central Processing Unit (CPU)
• A Logic Chip
• Instructed by Basic Input – Output System (BIOS)
• Operates on numbers and symbols
• Represented by numeral binary system
Note: It is general purpose device

3. What is Bit ?
• Microprocessor run by bit
• Unit of Information
• Microprocessor run by bit
• Used for computing and digital
communications
• Values are 0 and 1

4. 8085 Microprocessor
The Intel 8085 ("eighty-eighty-five") is
an 8-bit microprocessor produced
by Intel and introduced in 1976. It is a
software-binary compatible with the
more-famous Intel 8080 with only two
minor instructions added to support its
added interrupt and serial input/output
features. However, it requires less
support circuitry, allowing simpler and
less expensive microcomputer systems to
be built.

5. 8086 Microprocessor
 The 8086 ("eighty eighty-six", also
called iAPX 86) is a 16 bit microprocessor chip
designed by Intel between early 1976 and
mid-1978, when it was released. The Intel
8088, released in 1979, is a slightly modified
chip with an external 8-bit data bus (allowing
the use of cheaper and fewer supporting ICs),
and is notable as the processor used in the
original IBM PC design, including the
widespread version called IBM PC XT.
 The 8086 gave rise to the x86 architecture,
which eventually became Intel's most
successful line of processors.
