The document discusses microprocessors and their components and applications. It begins by defining a microprocessor as an integrated circuit capable of carrying out computer program instructions by receiving, interpreting, and executing actions. It then describes how microprocessors act as the "brain" of a device by communicating with other parts to control functions like output display. The document outlines the typical components of a microprocessor including the CPU, cache memory, decoder, arithmetic logic unit, and control unit. It lists some common applications and types of microprocessors including uses in PCs, instrumentation, control, and communication. It also addresses that while PCs can use dual-core chips, only one microprocessor can be used in a computer due to control and speed limitations

3. WHAT IS
MICROPOCESSOR?

4. O Microprocessors are integrated electrical
circuits that are capable of carrying out
the instructions of a computer software
application or program. These electrical
circuits receive instructions from the
application or program, interpret these
instructions and execute an action or set
of actions, based upon what the
instructions call for.

6. Why is a Microprocessor
Important?
O A device that uses a microprocessor is normally
capable of many functions, such as word processing,
calculation, and communication via Internet or
telephone. However, for the device to work properly,
the microprocessor itself has to communicate with
other parts of the device. For example, a
microprocessor would need to communicate with the
video display to control the output data that a program
may produce. Therefore, a microprocessor would act
as device's "brain" in that it transmits, receives and
interprets the data needed to operate a device.

17. CAN WE USE MULTI
MICROPROCESSOR IN PC?
O PCs have dual-core central processors
(CPU). That's one chip with two complete
microprocessors on it, both sharing one path
to memory and peripherals.
O Does we can use many M P in computer
O We can not use more than a microprocessor
in the computer because everything that I said
the number control units quality and speed of
work
