hello and welcome to our new video so in last video we have
seen what is a computer's block diagram and we have
understood that there are many components which we
integrate after integrating them a proper system is created
which can work it is not like
different components of computer or parts of computer can
work independently what they do they integrate and then
start working so now we have understood that in computer
there are three things which are very important one is
input one is processing and
then output today we are going to see what are the
applications of computer means in real life where and how
computer is used we have studied that line that line was so
popular that everyone started using it teachers are using
it managers are using it
students are using it filmmakers are using it so what is it
bankers are using it so when it became so popular we have
seen its characteristics that it gives speed, it is
reliable, it is versatile all these things let's see where
we get to see it in real
life where I can see its use so all these things we will
try to know in application so here I will tell you what all
things we are going to see what we are going to discuss
like in computer application the first thing is business
means in business somewhere
computer is being used second thing is banking when you go
to the bank you can see computers everyone must have
noticed that people are sitting in front of computers so in
banking we know that it is ok after that insurance life
insurance or not term insurance
vehicle insurance life insurance now we will study exactly
where it is used and what exactly it does so after this
let's see what are the other applications we have in
education in education students or teachers they teach
laptop or pc or students so
what we can say in education so this is the fourth category
education after this we can see in marketing in health care
after this what all applications we have in computer
application in engineering design computers are used apart
from this in military
so this is in engineering design after this it is used in
military in communication if you don't know we will discuss
in detail now we are just seeing where it is used if
someone asks you where it is used you will say that it is a
computer it is reliable
it has versatility so it is used like this if someone asks
you where it is used you will say that you don't know so
you should know these applications it is used in military,
banking government and communication so you should know all
these things after
this government uses it so now one by one we will
understand in which field exactly government is using it so
let's go first and see in which field it is used so first
of all it is used in business here is computer application
we are reading following
the list demonstrate various applications of computer in
today's arena in today's time this is demonstration we are
demonstrating that there are many applications where
computer is used first application is business so let's
understand what is written
here a computer has high speed of calculation it calculates
with speed it has diligence it has accuracy 99.9% of 100 it
is reliable it has versatility
I have talked about all these things so what is all these
characteristics which we have read in previous videos after
this what is written which made it an integrated part in
all business organization now if you see
Tata's organization there also you will see that computer
is used now what is Tata's organization business Adani
Ambanis what you have seen you have seen there also
computer is used here also computer is used computer is
used in business organization
now let's see what are the roles so first of all payroll
calculation what is payroll you have to give salary so to
give salary you have to have some data so what we can do in
computer we can make data in my company if 1000 employees
are working so what
I can do
I have paid 1000 employees which day they came which day
they didn't come so where we can keep data of all these
things we can keep in software and where we can see that
software we can see that software so for us it will be easy
now I don't have to keep
in mind or maintain diary that he didn't come that day he
went in half day all these things who will be responsible
for it my computer will be responsible for it in budgeting
like India's budget government brings budget any
organization has a budget this
year we are going to spend so much money we are going to
spend 500 crores from which we will buy raw materials now
all the details of raw materials where you will maintain
that you will maintain in all computers after that how many
salaries we are going
to give to employees how many hikes in salaries how many
new employees we are going to hire all these things where
we are going to maintain we will maintain in computer after
that we will do sales analysis that we have done sales last
year but now we
are going to do analysis that our projected whatever we
were taking target that we have to earn so much revenue we
have to earn so much revenue so that if it didn't happen we
couldn't earn that much so we will do analysis that sales
was not good our product
was not good so all these things you will get to see in
sales analysis and how you will do sales analysis you will
do it on the basis of data that this is the data of January
this is the data of February this is the data of March this
is the data of April
so all this data you have where you will keep it you will
keep it in any software you will do analysis with the help
of software next thing is financial forecasting that you
are looking at the market that this is going on in the
market so you are seeing
that this product is going to sell a lot this time like
covid came suppose covid came everyone needed mask everyone
needed sanitizer so the companies that make sanitizer
calculated as it happens you must have seen a lot of
software where you put your
name you put your signature you put your date of birth and
it gives you a prediction that your life is going to be
like this it gives you a slight prediction so if I have to
do financial forecasting like now if you want to see tell
me if I ask you or
your mother what to do, wash clothes today and she told you
that tell me after seeing the weather forecast forecast
means pre-prediction that you are trying from the beginning
that I get a little idea that today is going to be sunny or
not if today is
not going to be sunny then why to wash clothes similarly,
financial forecasting is done that in this financial year
in 2023-2024 in this financial year how many products
should we prepare people will be higher people will be
higher there is a recession
that Mandi has come in the market now if Mandi has come in
the market people will not have money So this is financial
forecasting.
So we need to maintain stock.
Let's see real life example of stock maintainment.
You have been to a pharmacy.
Like in a big store, they have a diary.
Have you ever seen this?
So as you go to a pharmacy, you show them prescription of
medicines.
If she does not have it, or even if she has it, then after
giving it to you she will write down the amount of
medicines.
So what he does, he is writing manually, he is writing on a
diary, but some people can also do this that the whole
software is made inside the computer and they keep doing
plus minus there that it was in stock as soon as you gave
it, as soon as you made
the bill, then what happened automatically, that much
leaves were reduced from there, that much product was
reduced, that much number of products were reduced, so you
keep finding out that
I have so much stuff in stock, how much do I need to make,
it does not waste, so what happened to all these things, we
saw that where is it being used in the business, after that
let's go next, what is next, banking, so today banking is
almost totally
dependent on the computer, when to go to the bank, what
will you see in the bank that all the employees
are sitting in front of a computer system, so what happened
that totally your banking depends on your computer, bank
provides following facility, bank provides online account
facility,
now you do not need to go to the bank, the bank has made
its own application, what you have to do, or the bank has
made its own website, you go to that website, get the
online account at home, so how are you able to do this,
either you are able to do
it with a mobile phone, or you are able to do it with a
computer, except these two things, you are not able to do
anything else, so what is here that the computer is being
used automatically, which includes current balances,
deposits, overdrafts, interest
charges, shares and trustee records, that is, an application
for every bank, like I use HDFC, so HDFC has an
application, someone may use Bank of India,
or someone uses Bank of Baroda, or someone uses State Bank
of India, so everyone has an application, you can put that
application in your computer, and you can see how much is
my current balance, how much I have to deposit, how much
overdraft has happened,
how much is my interest charge on someone, how many shares
I have bought, so all these things you can see in an
application, now how will you run the application, how will
you run the software, you need a computer to run it, so in
this way the use of
the computer is happening in banking, now what is written
next, ATM machines are making it even easier for customers
to deal with banks, so here the ATM machine, now what is an
ATM machine,
ATM machine is an electronic machine, it runs on
electricity, so it is a kind of computer or not, how do we
know whether it is a computer or not, see whatever
electronic machine is, see three things in it, if there are
three things, then understand that
it is working like a computer, what are the three things,
first it takes input, then it processes, then it gives
output, so explain to us what the ATM machine is doing,
let's take the example of the ATM machine, have you ever
gone to the ATM machine,
first of all, what does it make you do, that brother, put
the number of your account, after putting the number of
your account, put the money, how much money you need, you
have to select there that your current account or savings
account, after doing
this, that is, how did the ATM machine take the details of
the bank, how did the ATM machine take the details of the
bank, it takes input, after that it processes, processing
means it goes and checks your details, that whatever
details you have put, is
it absolutely correct, if it is absolutely correct, then
after that, what do you get in the output, all the money
you have put, you get it as a output, so where can we see
that it is being used in banking, after that, what is the
next thing, insurance,
tell me how it is being used in insurance, insurance
companies are keeping all records up to date with the help
of computer, that how many people have been sold policy,
how many people have claimed from those people, now see,
like computer
and mobile, it is the same thing, that whatever you are
doing in mobile, you are doing the same thing in computer,
so you suppose that if God forbid, someone in your house is
sick and then what you have to do, you have done health
insurance, so you need
a claim from there, so whatever is the status of that
claim, whatever information is there, where will it be
found, it will be found on its app, it will be found on the
company's app, and you can open your laptop and see it, or
you can open your mobile
and see it, because carrying a laptop is a way, I will say
that it becomes very difficult, but everyone can carry a
mobile, so you will get to see the application in the
mobile, in the application you will get to see whatever
your status of the claim
will be, so companies keep all the codes, the insurance
company finance houses and stocks broking, firms are widely
using computers for their concerns, it means that whatever
companies are there, financial houses are there, who are
the financial houses,
who give you money, the stock is broken, like
Jirodha, firms are widely using computers, what do they do,
they use computers, their applications also come somewhere,
so what can you say that in insurance, it is being used,
after that it is written that insurance companies are
maintaining a database,
now what is the meaning of database, database means that
here your record is kept, database of all clients with
information showing, now what is the information, what is
the procedure to continue with the policy, starting date of
the policy, now I will
show you how something
is going to look, suppose this is how your database is kept
in a table form, here columns are made, after that rows are
made, and with the help of these rows and columns, what we
are doing is that whatever our customer has, whatever data
he has, we do
all of it, we
keep it in it, so how will they keep it, let's see quickly,
here see what are the things, let's try to understand that
thing once, this is my database, now database can be
different, their names can be different, database is like
where your data is stored
and you are bringing it with the help of a query, like
procedure to continue with policies, that
here one place is written that what is the procedure, that
if you want to continue the policy, then how much money you
will have to pay, then you will get to see that, you can
keep the record of the database, starting date of the
policy, so what is here,
I have put it in a column, starting date, okay, how to do
this, starting date name, okay, name of
the customer, here we put the name in the first column,
after that here, okay, here we put the name, we make a
column of this name, then here we make the starting date as
date, and after that what we get to see, next due
installment, we put the due date,
due means that you have to fill up to this date, otherwise
penalty will be applied, after that what is here, we put
the maturity date, and after that what is here, we put the
interest rate, that how much interest rate you will get,
after that what is
survival benefit, that brother if you continue the policy,
then what you are going to get, after that here we put
another column, what is that, bonus, that how much bonus
you will get, if you do not claim any
policy, so now see here, what they can do here, like here,
now the insurance company sells, it does not have the data
of one person, after that it has the data of many people,
so how does it keep in the database, like here it is
written, Rahul, here it
is written that what is the starting date, it is 1
February, 1 to 2023, what is the due date, due date is 31
January 2024, after that what is there, here it is written
that
The maturity date is after 10 years, so what will happen in
2034, the maturity date will come in February 2034.
After that, what is the interest rate, what is the survival
benefit?
They said that your 1 lakh will be added to your account.
If you do not use it, then there is bonus in unused, they
add 1 lakh more.
So, as I told the data of one customer, the data of another
customer can also be like this.
Here, the name is Deepak.
What did Deepak do? Deepak got it done on 15th December
2013.
When is the starting due date?
Let's take this as latest, let's take 2024.
After that, what is the due date? 14th February 2025.
After that, what is the maturity date?
It is a policy of 10 years, so the maturity date is 2035.
What is the interest rate? 9% interest rate.
After that, how much money will be there? 5 lakhs will be
there.
What will be the bonus of survival benefit? 1 lakh will be
there if you do not claim.
So, in this way, what does a company keep in a database?
It keeps customer data.
Now, where will you get to see this?
In a computer.
So, what can we say?
When an insurance company has to use a database, what does
it do?
It keeps it in a computer in this way.
So, we can say that in the field of insurance, what do you
get to see?
You get to see a computer.
After that, what is education?
Now, let's see in education that how are you getting to see
in education?
In education, the computer has provided a lot of facilities
in the education system.
Now, let's see what are these facilities?
First of all, the computer provides a tool in the education
system known as CBE.
Computer Based Education.
Now, what is Computer Based Education?
Let's try to understand this.
CBE involves control, delivery, and evaluation of learning.
Now, if you have heard the name of Byjuice, then Byjuice
tablets are available.
Or there are many adtech companies that give you the
opportunity to study in their app.
Now, when you go inside the app, suppose there are 300
lectures in it.
So, when you finish the first lecture, it will tell you
that you have completed 1%.
If you have seen 5 lectures, it will tell you that you have
completed 3%.
If you have recorded 10 lectures, it will tell you that you
have done this much.
So, where will you get to see all those things?
You will get to see all those things in their application.
Now, where will you get to see this application?
You will get to see this application on the computer or on
the mobile phone.
If you go somewhere to give a test, which is a computer
based test, then what happens there too?
They conduct it on the computer.
So, what happened?
There is an application that the computer is used there too.
If you want to show PPT to the teachers, if you want to
explain a topic, then what can they do?
They can take help from the computer.
After that, it is written that the computer education is
rapidly increasing the graph of number of computer students.
It is spreading so fast that the number of computer
students is increasing.
What happened during the COVID?
Do you remember?
During the COVID, people were not able to leave their homes.
Now, when they were not able to leave their homes, they had
to teach.
How will you teach?
If you want to teach online, then you need a device to
teach online.
You need a computer.
What did I say?
Take the computer and the mobile phone together.
Whatever your mobile phone is doing, the computer is doing
it.
The computer is doing it on a big screen and the mobile
phone is doing it on a small screen.
So, what did we see in education at that time?
We saw that a lot of people are buying new devices.
Either they are buying computers or they are buying phones.
Why are they buying?
Because you will study through an application.
Now, the teacher who will teach you will also use a
computer.
The student who will study will also use a computer.
So, here we are able to understand that almost everyone has
a mobile phone.
So, the computer is also increasing in this way.
Why is it increasing?
Because it is making your work easier.
You can talk to your friends.
These days, there are such apps where you can work and talk
at the same time.
Now, you will see that where you go to study in schools and
colleges, what you get to see there?
You can use the computer in different ways.
If you want to explain something, they will put you on the
computer.
Or you can connect the computer to the projector and teach
you.
So, how can they do all these smart things?
With the help of the computer.
So, what can we say?
We can educate the student in an institution.
With the help of whom?
With the help of the computer.
It is used to prepare a database about performance.
Now, we have made a database.
Now, we will write the student's name in the database.
How many marks did the student get in the Sessional 1?
How many marks did the student get in the Term 1?
How many marks did the student get in the Mid-Term?
How many marks did the student get in the Final Exam?
By taking an average of all these, we can make a database.
We can make a database and do an analysis.
Is it necessary to pay more attention to this student or
not?
Is it necessary to pay less attention to this student?
So, how can you do all these things?
You can do all these things with the help of the computer.
Now, the next thing is Marketing.
So, tell me how is it being used in marketing?
In marketing, use of computer and advertising.
Now, tell me, do you see advertising in any of the things
you see?
I have opened a browser in Chrome.
I have opened a website in Chrome.
I can see the advertisement of different companies on that
website.
Or, I can see the advertisement of any application that I
open in my mobile phone.
I can see the advertisement when I open YouTube.
So, companies can do advertising.
What is the targeted audience?
People who use computers, people who use mobile phones.
So, they can do advertising.
With computers, advertising professionals create art and
graphics.
Now, the people who want to show, they are using computers.
To show an ad, you have to take a software on a computer.
In that software, you have to create graphics.
You have to write.
You can copy and then print.
So, you can see all these things with the help of a
computer.
After that, it is written,
Home shopping has been made possible through the use of a
computerized catalog that provides access to product
information and permits direct entry of orders to be blah
blah blah.
Let me explain what is written here.
What does it mean?
Let's understand the meaning of these two lines.
Suppose you go to the offline market.
You go to the market near you.
And you say, show me this shirt.
Now, they have a hundred types of shirts.
You can see in front of you.
What will you do?
You will say.
You will choose to show this shirt.
Brother, show me this shirt.
So, you can open 20 shirts.
After that, we also feel ashamed.
Why are you bothering me when I don't want to buy it?
So, you don't open 21 shirts after 20.
You don't tell him to open 100 shirts and show me.
Then I will not like it.
Neither will he open and show it.
Nor will you open and see it.
Because you know that brother will be worried.
So, what can you do?
When they can't show you all the shirts on the table in
front of you.
Can't keep it.
So, it means that whatever catalog they have.
But they can't show you the catalog properly.
So, what is used here?
Here comes the use of the computer.
How does the use of the computer come?
There is a website called Mintra.
Go to Mintra.
Go to the men's section.
There is a list of jackets all over the world.
You can select any one.
You will get to see 100 types of jackets.
You will get to see 200 types of jackets.
You will get to see 500 types of jackets.
You scroll on the mobile phone or computer.
Order whatever you like.
Sitting at home.
So, how are these things happening while sitting at home?
Things are happening while sitting at home.
You can see how to find different types of diseases.
You can find all the details on the computer screen.
After that, if I talk about ECG, EEG, ultrasound, CT scans,
are also done by computerized machine.
With the help of computer, they can tell you whether your
disease is increasing or decreasing.
With the help of computer, they can generate reports for
you.
Some major field of healthcare in which computers are used
are 1.
Diagnostic system
If you are diagnosed with a disease, they will diagnose it
with the help of computer.
2. Computer are used to collect data and identify cause of
illness.
3. Lab diagnostic system
Diagnostic system is used to check patient signs for
abnormalities such as cardiac arrest, ECG, etc.
4. CCU
CCU is used to check heart patients.
5. Oxygen mask 5.
Oxygen mask is used to monitor patient's health.
6. Pharma Information System 7.
Computer are used to check drug labels, expiry date,
harmful drugs, side effects, etc.
8. Surgery
8. Surgery is done with the help of computer.
9. Engineering Design
Computers are widely used in engineering purposes.
One of the major area is CAD.
CAD provides creation and modification of images.
Some fields are
Structural engineering
Requires stress and strain analysis for design of ships.
Design of buildings, budgets, airplanes etc.
Industrial engineering
Computer deal with design, implementation, improvement of
integrated systems of people, material and equipment.
Architectural engineering
Computers help in planning towns, designing buildings,
determining a range of buildings on a site using 2D and 3D
drawings.
Computers are widely used in military.
Computers are widely used in defense.
Modern tanks, missiles, weapons, etc.
Military also employs computerized control systems.
Some military areas where a computer has been used are
missile control, military communication, military
operations and planning.
Some military areas where a computer has been used are
missile control, military communication, military
operations and planning.
Computerized means a small system is installed in it.
In which you can set things from the beginning.
When you launch a missile, it is computerized.
So, there is a computer being used in some form.
Computers are used for defense.
And understood clearly and correctly by the person for whom
it is meant for So, if you want to show the picture for
whom it is made, how will you be able to do this?
With the help of a computer Some main areas in this
category are email If you want to do email, chat, usenet,
ftp, telnet, how will you be able to do all these things?
Or video conferencing For example, IT firms do work from
home, but before that, there is a meeting What happens in
the meeting?
In the meeting, they decide what work they have to do today
And they do video conferencing for this So, how is video
conferencing possible?
Either with the help of a mobile phone or with the help of
a computer What is a mobile phone in a way?
If you have a small computer in your hand, then if you want
a big computer, then it is a big screen computer After
that, let's see the last point, government How does the
government use it?
Computers play an important role in government Some major
fields in this category are budget Now see, the budget is
coming on 1st February
Or every year the budget comes on 1st February
So, our finance minister brings a computer in his hand,
brings a tablet
From that, she tells all the things that we are going to
bring this year So, what happens in the budget?
What is used to prepare the budget, to study the budget?
Computer is used Sales tax department What do people in the
tax department do?
They also use it
How many people have filed ITR this year?
How do they file?
They file with the help of a computer
How many people have to send money back?
How will they keep a record?
They will keep a record from the computer
What is the ratio of male to female?
Government keeps a data of this thing
Like census is held every year
Some people come to your house
After that, they come to your house and get information
How many people live in your house?
How many children go to school?
How many people go to work?
So, they prepare a record of all these things
And with that record, they can find out
What is the ratio of male to female in the country?
When they have all the data collected
So, where will they put all the data as input?
They will put it in the computer
And what will you get?
They will get the output
And what will the government get?
They will get the result
In which they can tell you
What is the ratio of male to female?
What is next?
Computerization of voter list
The list of voters will come to your computer
You can see
Is my name in the voter list or not?
So, how are you able to do all these things?
You are able to do this with the help of a computer
What is next?
Computerization of driving license system
In today's time
If you pick up anything
The governance
The digital governance is happening
That means
If you want to get a passport
You don't have to go anywhere
You can apply it online
If I want to pay the electricity bill
You can pay it online
If you want to pay the water bill
You can pay it online
If you want to pay the house tax
You can pay it online
If you want to pay the house tax
You can pay it online
If you want to pay the development charge
You can pay it online
So, almost in every field
The computer is being used
It has become an integral part of you
The way
A computer system
Is integrated in itself
All your devices
Come to you integrated In the same way
You can say
Computer and mobile
Integrated part
Computerization of PAN Card
PAN Card
Detail Online Online Online Mobile you can save it
digitally and you can use it digitally and you can use it
digitally weather forecasting what did i give you? i gave
you example in starting when we were doing finance
forecasting in weather forecasting
i told that my mom has to wash clothes so she asked me how
is the weather going to be today? is it going to be sunny
or not? if not then washing clothes will be cancelled and
if it will be sunny then washing clothes will continue now
how are all these
things happening? where do you see? first you go to mobile
mobile is a small computer or if you have laptop and
internet connection you can put it in your computer after
doing all these things you will know how is the weather
going to be tomorrow you
will know how is the weather going to be next 10 days after
10 days you will know if i have to go to kashmir to travel
is it snowing in kashmir or not? you will know the
temperature there if you have to go to rajasthan to travel
now its too hot your temperature
in rajasthan is 44 degree so you can delay the plan so
computer is controlling your life and doing your work
easily if computer is not there you will not know what is
going on in other city or other state how is the weather
there after doing all these
things you will know how is the weather in other state so
who is helping you? computer is helping you so lets see
what all fields we have studied so we have learned about
computer application if someone ask you where is computer
used you can easily tell
them it is used in business how is it used in business? to
do budget, sales analysis, financial forecasting it is used
in banking all employees are using computer insurance
companies prepare data which customer has bought my policy
what is the starting
date due date, maturity date interest rate of insurance
bonus how will you get all these things how will you get
all these things after that we have seen education where is
it used for exam if you want to see result then computer is
used
I hope you all know what are the applications of computer.
If anyone asks you, you can easily answer.
This video is about computer fundamentals.
We have learned that computer is an electronic machine.
It takes input, processes it and gives output.
We have seen that computer is very popular among people.
Managers are using it, teachers are using it, students are
using it.
Why are they using it?
Because it has characteristics.
What are those characteristics?
It has versatility.
It does tasks in different ways.
It is reliable.
It has speed and accuracy.
It is popular among people.
We have seen that managers are using it.
