Uses of computer in Different Fields

Today, many types of computer are used in our
everyday life. In most parts of the world, it's
impossible to use a product or service that doesn't
utilize a computer. Below are examples of the
industries, areas, and different fields using
computers.

BANKS & FINANCE
Computers play a significant role in handling all of
the world's money. Below are examples of how
computers are used in the financial market and
places dealing with money.

 ATM - When you make a withdraw from an ATM, you are
using a computer.
 Digital currency - When depositing money in a bank, it is
stored as a digital record. A computer keeps track of how
much money is in your account.
 Trading - Stocks and commodities are traded using
computers. In fact, today there are even thousands of
computers using advanced algorithms that handle trading
without needing humans.

 Register - If the business deals with selling goods to a
consumer (e.g., a grocery store), a cash register, which is a
computer, is used to complete transactions.
 Workers computer - Many businesses assign each employee
a computer that allows them to produce work and solve
problems for the company.
 Server - If the business uses computers, connects to the
Internet, or handles e-mail and files, a server is used to help
manage everything.

COMMUNICATION
Today's communication around the world is
almost all digital and handled by computers.
Below are examples of how computers are used
in the communication industry.

 Smartphone - If you have a smartphone, you have a
computer in your pocket.
 E-mail - More electronic mail is sent today than postal mail
and computers handle all creation and distribution of that
 e-mail.
 VoIP - All voice over IP communication VoIP is handled and
done by computers.

 Computer-assisted speech - Those who are disabled or
cannot speak can use a computer to help them
communicate. For example, Stephen Hawking uses a
computer to communicated.
 Voice recognition - Any phone or another system that
uses voice recognition is using a computer to translate
what is heard into text or other data that can be
understood by the computer.

DEFENCE & MILITRY
Many technologies (e.g., GPS and the Internet)
were initially created or started with a defense-
related purpose. Today, computers are still an
important aspect of the defense industry.

 Encryption - Secure communication is vital in the defense
industry and computers are used
to encrypt communications that should remain secret.
 GPS - Using computers with GPS allows the military to
track people and equipment and is still used today.
 Computer-aided flight - Many of today's jets and other
aircraft require computers to fly and operate.
 Drones - A drone is either autonomous or remotely driven
and uses computers to operate.

EDUCATION
As computers evolve, so does how computers are
used in the education field. Below is a list of how
a computer can be used in education.

 Internet - Connecting a student to the Internet gives him
or her access to an endless supply of knowledge. As
mentioned later, the Internet would not be possible
without computers.
 Learning - Computers can also be used to help design and
create a more visual learning experience for students.
Using electronic whiteboards with computers can also
benefit a student by giving them a more hands-on
experience.

 Writing - Although reports can still be done using pen,
pencil, or even a typewriter, a computer makes it much
easier to write, format, save, share, and print reports.
 Keep records - Computers are used to track students
scores, identify struggling students, and are used to create
a final report.
 Testing - Computers can assist students and teachers with
the testing process by stepping the student through a
series of questions and keep track of the results.

MEDICAL
The medical field is another place where
computers are vital and used every day. Below
are some examples of how computers help those
in the medical field.

 Medical records - More and more medical records are being digitally
stored. Storing these files digitally allow for quick access and transfer of
medical information so doctors can know your history.
 Research - A lot of the medical research that is done today is computer
assisted. Without the assistance of a computer, it would either not be
possible or take so much longer that it wouldn't be viable.
 Diagnosis - Computers can assist in the diagnosis of a patient, from
gathering a patient's history and conditions to comparing that information
against a database of existing information.
 Surgery - Although most surgery is still done with humans, it is becoming
more practical and accessible for computer robot-assisted surgery. After
being programmed, these robots can make surgery more accurate, faster,
and less prone to human errors.

TRANSPORTATION
Computers also play an important part in
transportation. Below are just a few examples of
how computers help the transportation field.

 Cars - Most may not realize it, but all modern cars today have dozens of
computers that help control and manage the vehicle.
 Traffic lights - The traffic lights that help control traffic are all run by
computers.
 GPS - Cars that include a GPS mapping system have computers for display
and calculating routes.
 Airplanes - The airplanes that help transport millions of people and goods
every year are filled with computers that help control the plane.
 Public transportation - Train, bus, subway, and all forms of public
transportation are highly dependent on computers to manage traffic flow,
monitor operation, and handle payments.
 Self-driving cars - Although relatively new, self-driving cars are becoming
increasingly popular and rely on a computer to make all decisions on how
to drive.

MULTIMEDIA
Computers also play a significant role in video
and audio. Below are examples of how
computers are used in the film and audio
industry.

 Editing - Once a movie, video, song, or audio track has been created a
computer can edit that media instead of having to manually make cuts to
the film or audio track.
 CGI - Computer animation and CGI (computer generated imagery) has
become a norm in big budget films.
 Manipulation - Computers can be used to manipulate pictures, video, and
audio. For example, someone could use Adobe Photoshop to add or
remove elements from an image.
 Recording and playback - Computers can also be used to assist in the
recording of audio tracks and then selectively playback each audio track.

 Creation - Computers can also be used to help in creating new multimedia
content. For example, creating 3D animation, 3D model, or a techno audio
track can be done on a computer. After creating a 3D model, a 3D
printer could also be used to build a product.
 TV, DVD, media players - Today's Smart TV, DVD players etc., contain
simple computing circuitry to connect the device to the Internet, run apps,
and more.

SIMULATIONS
Some problems are so complex that it would be
impossible for humans to calculate or would take
too long to calculate. Computers are used to help
solve these complex problems in a timely fashion.

 Weather prediction - Earth has an extremely complex weather
system, and computers are used to gather all of the variables and
create weather reports.
 Product simulations - Before some products go into
development, computers simulate how they would work in the
real world. By creating a simulation, a company or government
agency can make adjustments before the product goes into
development.
