Welcome to our new lecture
So today we are going to talk about
Motherboard Now what is motherboard?
How does it look? I am going to show you all these things
And we are going to talk about it in great detail
We will take it in the reference of
Mobile phone
I will tell you that there is a thing in mobile phone Which
is called SOC
Now what is the meaning of this SOC?
I will show you this SOC
First of all, I will show you How does the motherboard look?
You must have seen it sometime
You can see
The green color board
You can see it from behind
There are many things on it
So what do we call it?
We call it motherboard
Now you can see it in such a big size
Whose motherboard is this?
This is your computer's motherboard
And if I put it in a small size and put it on the mobile,
we change its name
What do we say there?
We call it SOC
It means System on Chip
Here if you
We had said that there are different components of the
computer
So where do all those components come? They come here You
will see it here
What will you get here?
CPU When we talk about RAM
So where is the RAM?
RAM slots are given here
So RAM will also be here
About ports, although we will read in the coming videos
But here you can see
For ports
It is given on this motherboard
That ports are given
You can connect from here
Whether it is a USB port
Whether it is a LAN cable port Apart from this, you will
see a lot of different things here And all these things
If I can show you from behind So who is it connected to?
What did we increase?
When we came in the fifth generation So there you got to see
What did you get to see?
Integrated circuits
So here these little things that you can see
What are all these things?
These are integrated circuits
Which are connected to each other
Through which electricity passes
And we know that the computer understands things
What to do
What not to do
We have to talk about another video
Which is about number systems
That is, whenever you give any data to the computer
Or whenever you give any instructions to the computer
How does the computer convert it?
Now this thing
Will be applied on every electronic machine
So what to do first
I open it first
You have an idea that how my motherboard is going to look
This is my motherboard
If you want, you can open your laptop
I will not suggest
Because it may be damaged
But If you have a bad mobile phone in your house
Or If you have a bad laptop or pc in your house
You can open it
You will see something like this
So let's see
What things have been written about the motherboard
Let's try to understand them one by one
Which are the companies
Which manufacture the motherboard
So from here
I open my whiteboard
And in the whiteboard
The definition is written here
So what is this
My computer's motherboard
About which we are going to talk
And understanders
Many times you will hear
Like the most expensive
When does it come
Like your
If any component of the computer gets damaged
It can be expensive or cheap
Like cpu can be expensive
Ram can be expensive
But suppose if your motherboard gets damaged
So what a big problem
That you have to bring a new motherboard
So how much will it cost
Now here you can see
Whatever I have shown you
Motherboard is same
As it is
Now because different companies make
So it is possible
The slots given here
This is slot number 1
This is slot number 2
This is your slot number 3
So it can be like this
That in one motherboard
In some motherboard you can see more slots
In some motherboard
You get to see less slots
This thing you are seeing
Here is your cpu
Control Processing Unit
Apart from this
What you will see here
You will see all these ports
Through which you can connect your keyboard
You can connect your pen drive
You can do all these things
See this is same to same
Once you look at the screen
I will show you
What you will see here
Here is your cpu
And this thing
You will get to see here
Here is same to same
If I talk about RAM slot
You will get to see this RAM slot
See here
In my motherboard
You can put 2 RAM slots
Here you have 3 RAM slots
So before reading its definition
When I told you
That even in a mobile phone
There is such a thing
What we call it
Let's see what SOC means
I will write it here
After this we will go to chrome
And we will see
The system installed in the mobile phone
How does it look
Is it so big
Is everything inside it
So we are going to talk about SOC
We will talk about it a little
Its full form is
System on Chip
What does it mean
Your whole system
Is installed on one chip
If that chip is damaged
Then there will be a problem
Like motherboard is damaged
If your chip is damaged
Then there will be a problem
So let's see how SOC looks
Then we will talk about motherboard
Once you understand motherboard
Then you will understand SOC
So let's open chrome
And what do we put
System on
Chip In mobile
Phones We enter it
And you will see
Let's read its definition
A system on a chip is a microchip
That is a small chip
We are not talking about macro
If we talk about it, then what is it
That you get a big one in size
But what is SOC here
It is a microchip
With all the necessary electronic circuits
What will you see on it
You will see electronic circuits
In SOC
And parts for a given system
Such as a smart phone
And wearable computer
What is wearable
I will show you
This is a smart watch
See this
This is a smart watch
This is a Samsung smart watch
What will you see in a small watch
You will see SOC
You can save data
Play store is given in it
If I install anything on the play store
And open it
I know
The executable file inside the computer
Where does it come to run
Comes in RAM
What happens in wearable device
When I
Open any app
The same thing happens here
The executable file of the app
Where will it come
It will come in RAM
In this small watch
I get to see SOC
And on that chip
All the necessary things
I will get to see my RAM
I will get to see my storage
I will get to see my CPU
You get to see all these things on it
A single
Integrated circuit
When we went to the third generation
When we went to the third generation of the computer
Let's remember
What did we read in the last lecture
When we were in the first generation of the computer
What happened in the first generation
The technology of vacuum tubes
But What was the problem of the technology of the vacuum
tube
The heat inside the vacuum tube
It used to be more and it was expensive
After that we found out
When we switched from the first generation to the second
generation
When we switched from the first generation to the second
generation
We found out that
We changed a little
We changed the technology
What technology did we bring
We brought transistors
After the transistor
We thought that let's do one thing
The different transistors that have been given to you
Let's put them inside an integrated circuit
So we took different integrated circuits
That is, we shifted
On integrated circuit technology
Now inside the integrated circuit
We found out
What can you do here 4 to 5 or numbers can be more or less
You will take the transistor
And you will put it inside an integrated circuit
After that we saw
When we went to the fourth generation
We found out that
The integrated circuits
What did we do
Very large scale
After that when we went to the fifth generation
Which is still going on
Ultra large scale
We started working on integrated circuits
Here we understood that
Motherboard and system on chip
Two are the same
What will you see inside the wearable
You will see the system on chip
But its size can vary
In the case of a computer
It can be this big
In the case of a mobile phone
It can be smaller
In the case of wearable
Let's see the images
Will our system on chip look like this
Or will it look completely different
So for this
I will open the images
See where it went
supports a single type of cpu and few types of memories.
3. Video Cards
4. Motherboard
5. WhatsApp
6. Android
7. Google 8.
Let's see next slide.
Motherboard, cases and power supplies must be compatible to
work properly together.
Now why people go to apple mobile? Can anyone tell?
Because apple hardware and software are very well
integrated and compatible with each other.
So that your motherboard, power supplies, cases can be
compatible with each other so that they can work smoothly
together.
Now let's talk about some of the popular manufacturers who
manufacture motherboards.
So what is Intel here?
You will see the name of Intel almost everywhere.
Intel's motherboards are also very good.
What happened to this?
You will get to see the motherboards of Asus, you will get
to see the motherboards of Aopen,
you will get to see the motherboards of BioStar, you will
get to see the motherboards of Gigabyte and MSI.
So what can you do?
You can remember 3 to 4 names from this that Intel's
motherboards are also available.
So next time when you go to the market to buy a
motherboard, at least you will have an idea that do one
thing, show me the motherboard of Asus.
Now this thing can happen that the motherboard that Asus is
providing is providing you 5000 but with the same features
Intel is giving you in 4000.
So you will get to do a comparison from here.
Or you can also choose other companies like MSI.
Next thing is, let's see the description of the motherboard.
What is the description here?
So it is written that the motherboard is mounted inside the
case and is securely attached by a small screw through
pre-drilled holes.
That means when you put it on, the motherboard that you
have is mounted, you can hang it
inside the case.
That means whatever will be your laptop or whatever will be
your cabinet will be securely attached by small screws.
You can put it through small screws.
As it happens that you want to mount your LED, you can
mount it on the wall.
Similarly, you will see screws in my motherboard.
You can screw here, you can screw here, you can screw here.
So whatever will be your laptop body, you will screw it in
that way so that it can stay there properly. Small screws
through pre-drilled holes.
That means the holes have already been drilled.
We don't have to do it.
Motherboard contains ports.
Now there are ports in the motherboard.
We will talk about this port in great detail later.
To connect all of the internal components.
Whatever internal components are there, you connect it.
It provides a single socket for CPU.
Now what is a single socket of the CPU?
You are seeing this white area.
This is your socket.
And what will be inside it?
CPU will be there.
Whereas for memory, normally one or more slots are
available.
What are we talking about here?
More than one slot will be available for me.
For memory, that is, for primary memory.
So look here.
One slot has been given here.
Another slot has been given here.
What did we see in the image?
More than two slots have been given here.
Three slots have been given here.
It is possible that you can see more than three slots.
So you will get to see different slots.
Motherboard provides ports.
To attach floppy drive.
Hard drive.
Now what are we talking about?
It is possible that you want to connect an external hard
disk.
So how will you do it?
Through the port.
We have seen this in the last few lectures.
If it is a floppy drive.
Or a hard drive.
Let me show you.
You can see this.
Here I can connect my hard drive.
Here I can connect my floppy drive.
What does this mean?
Drive and disk.
There are two different things.
Let me tell you.
People get confused.
Here I write.
Hard drive.
And let's talk about one thing.
Floppy drive.
And what is the word related to this?
Hard disk.
And what is the word related to floppy?
Hard disk.
Sorry.
Floppy disk.
Now let's see.
Let's go to google.
Let's see what is the difference.
Here I went.
And I put.
Hard drive.
So what do I see in the hard drive?
I see this.
Now I put.
Hard disk.
More or less you will see the same.
See.
This is what you see.
This thing.
This is your hard disk.
You put this.
Let me show you.
CD player.
See this thing.
See.
Floyd.
Hard disk.
Drive.
You keep this in there.
Drive.
you will get the card slot separately, it's not like you
will put it in the RAM slot and it will work.
The same thing happens for the sound card and the same
thing happens for the expansion card.
On the left side motherboard area number of ports, we have
already seen it, I will show you again.
What do you see on the left side?
You see a lot of ports.
Now what are these ports?
These are the ports that connect your keyboard, mouse, USB
cable, pen drive, etc.
Whether it is LAN cable, there is an Ethernet port to
connect LAN cable.
So you will see all these things on the left side.
What else is written here?
The same thing is written here about which we were also
talking.
Motherboard carries a number of ports.
To connect monitor, you have to connect the monitor through
the port.
To connect the printer, you have to connect it through the
port.
To connect the mouse, you have to connect it through the
port.
To connect the keyboard, you have to connect it through the
port.
Whether it is a speaker or network cable, how can you
connect all these things?
You can connect it through the port.
Motherboard also provides USB ports.
You can also connect it through the plug-in plug-out.
