hey guys hope you're all doing it and
welcome back to a channel I'm gonna
start this video with a weird statement
imagine you have to function without a
brain well that sounds downright
impossible right even while these words
are being said they're being registered
into your brain for understanding and
processing just like how the brain
serves as the functioning mechanism in
your body a microprocessor serves as the
functioning mechanism of a computer in
other words these micro processors are
the grain of your computer your mobile
phone and most other electronic devices
that you may use in your day-to-day life
in this video you will come across a
brief introduction to micro processors
now let me ask you a simple question do
you think that our fans and to blights
have a microprocessor in them if your
answer is no well you guessed it right
why do you think that well this is
because they don't require any
processing in them you basically switch
it on and your fan starts rotating at
the speed at which it is set similarly a
tube light starts emitting light when it
is switched on then what are the other
areas in which micro processors are used
micro processors are used in any
equipment that requires some sort of
processing to be done from the traffic
light two remotes to a computers all
have micro processors in them these
processors have an algorithm and they
work in a previously programmed manner
according to the instructions given now
you must be wondering where and how did
the invention of micro processors take
place well micro processors were first
invented 50 years ago at a young Silicon
Valley startup called Intel the first
microprocessor was the Intel for double
of four invented in 1971 and it was a
4-bit processor it was soon succeeded by
Intel aw8 in 1972 and since then the
development in micro processors has been
huge back in 2018 Intel released its AI
9 double 9 double zero K which is a
ninth gen processor and was claimed to
be the fastest gaming processor in the
world by Intel at that time now coming
to the components of the micro processor
they are divided into three basic
segments the ALU registers and a control
unit each of these has a specific
predefined role first component that is
the ALU or arithmetic logic units are
the building blocks they perform all
mathematical and logical calculation
on the data that has been fed into it
mathematical calculations include
addition subtraction multiplication
etcetera and the logical calculations
are the and or and not operations next
we have the registers the registers are
temporary data storage locations in the
microprocessor depending upon the need
they either hold data or point in the
direction where the data is located
registers are divided into three
categories namely general-purpose
registers specific registers and memory
registers depending on the need data can
be stored or extracted from them
accordingly the control unit controls
the operation in the microprocessor it
dictates how the internal memory of the
computer should respond to the given
instructions and controls the flow of
data between the microprocessor and the
system microprocessor is further
connected to the input devices memory
unit and the output devices the input
devices are used to feed information
into the micro processors the memory
unit is the internal storage unit of the
microprocessor it is commonly known as
the RAM this unit stores all data and
information that is required for
processing it also stores intermediate
results of programming finally we have
the output devices the output devices
provide the results of the data that has
been computed by the processor the
output can be in multiple forms it can
be in visual form when you consider the
monitor of your computer or it can be in
an audible form when you consider the
speaker of your computer next let us
discuss how the microprocessor works the
working of a microprocessor follows a
simple fetch decode and execute cycle in
this the microprocessor first fetches
the function to be executed from the
memory now the instruction is present in
an encoded form in the memory after it's
been decoded the control unit of the
processor then passes these decoded
instructions to be executed this cycle
continues till a stop instruction is
reached or till the program ends well
that's it for this video guys in this
video we learned about how micro
processors are an indispensable part of
any computational device how they came
into existence and how they function in
our upcoming videos we learn more
micro processors until the next one bye
