Some Other Applications Of Computer System
So,
Here Are Some Other Application Of Computer System.
Banking
Banking works in a real time environment and thus this sector
is totally dependent on computers.
Thus, computer is an indispensable part of the modern banking
system. The customer's data and transactions are stored for future use. Every
bank provides online facility. Recurring deposits (e-RD), fixed deposits
(e-FD), money transfer from one account to another (NEFT, RTGS), online
transactions are done using the Internet. Capital market transactions, Demat
accounts and related services are available in online banking Automated Teller
Machines (ATM) for cash deposits and withdrawal, or to view current balance are
made available at outlets that allows customers to complete basic transactions
without the aid of a branch representative or teller.
Know More
Many computer provide real time environment, this means processing
of one entity is done so quickly and effectively that another aentity is not affected.
Healthcare
There's no doubt that technology is the driving force behind
the huge improvements in healthcare. The majority of the hospitals today use
diagnostic tools or machines for ECG, EEG, Ultrasound and CT Scan and have
implemented modern technology such as the expert system in surgical rooms,
which has significantly reduced the mistakes made by doctors. Vaccines have
been incredibly effective, almost eradicated diseases such as measles,
diphtheria, and smallpox. It has increased lifespans and improved the quality
of life for people worldwide.
There are also many health-related phone and desktop apps that
allow you to easily monitor your weight heart rate and other health aspects at
any time of the day.
Hospital Management System is used to maintain and manage
patients' records as well as various activities pertaining to hospital
administration.
Following are some major fields of health care in which
computers are used.
· Diagnostic
System - Computers are used to collect data and identify the cause of illness.
· Lab-diagnostic System - All tests can be done
and the reports are prepared by computer
· Patient
Monitoring System - These are used to check the patient's signs for abnormality
such as in Cardiac Arrest, ECG, etc.
· Pharma Information System
- Computer is used to check drug labels, expiry dates, harmful side effects,
etc.
· Surgery - Nowadays,
computers are also used in performing surgery.
Engineering design
Computers are widely used for engineering purpose. One areas
is CAD (Computer Aided Design) that provides modification of images. Some of
the fields are:
· Town
planning
· Design of
airplanes, ships and buildings
· Design of
materials and equipment
Defence
Computers
are largely used in defence in areas such as:
· Missile
control
· Communication
· Operation
and planning
· Smart
Weapons
· Weather
reports
· Administrative work
Communication
Communication is a way
to convey a message that is received and understood clearly and correctly by
the person for whom it is meant. Some main areas in this category are:
· E-mail
· Chatting (WhatsApp)
· FTP
· Video-conferencing (Skype)
· Social networking
(Facebook, Twitter, Instagram)
Insurance
Insurance companies
finance houses and stock broking firms keep all their records up-to-date with
the help of computers. Insurance companies for example, maintain client
database with the followini information:
· Procedure to continue
with policies
·
Starting date of the policies
·
Next due instalment of a policy
·
Interests due
·
Bonus
·
Marketing
and Retail
·
Maturity
date
· Survival benefits
Marketing
and Retail
Computer are also used
for marketing products in the following ways:
· Advertising: Using computers, advertising
professionals create ads with the goal of selling more products. The design,
graphics, write and revise copy and print, all these steps are done using a computer.
· Home Shopping: The catalogues that
provide access to product information and ordering the products is done with
the help of computers.
You enjoy the benefits
of buying anything 24/7. You use this facility to choose from a range of items
on the Internet at any time or any part of the globe. Technology has also made
the buying and selling of goods and services so flexible and a lot safer. You
can pay for the items on the Internet with a safe internet payment option.
Railways
and Airports
Railways and airports
make best use of computer for:
Enquiry about
reservation
Ticketing
Processing large
volumes of financial data
Entertainment
Computers are widely
used by entertainment industry specially to give special effects in movies; movies like Jurassic Park and others are
made using computers. Musical Instrument Digital Interface (MIDI) is used to
record music.
Law enforcement
Advance techniques are used by the police to recognize the
criminals. For example, national fingerprint files, retinal checks, matching
faces and computer modelling of DNA, which can be used to match traces from an
alleged criminal's body, such as blood at a crime scene. In addition, to
maintain a database of all the names, pictures and information to recognise
criminals.
Computers are also used in fields like agriculture (for crop
information and cost per acre, feed combinations and market price checks); energy
(to locate oil, coal, natural gas and uranium); Cattle ranchers (information
about livestock); transportation (to
monitor petrol levels,temperatures and electrical systems, air control traffic
systems).
Components of a Computer System
A computer can process data, pictures, sound and graphics. A
computer performs the following major operations or functions irrespective of
their size: Process data as required by the user
· Accepts
data or instructions
· Gives
results in the form of output
· Stores
data
· Process
data as required by the user
Know More
Data are raw
facts and figures or in other words it is unprocessed data. Data is plural of
datum.
The computer system consists of three main units:
· Input
Unit: The devices that are used to enter data into the computer;
for example, keyboard, mouse, scanner.
· Central
Processing Unit (CPU): It performs the operations (arithmetic or
logical) as per the instructions.
· Output Unit:
The devices that are used to show the result after processing of data; for
example, monitor, speakers, printer.
All these units work together to make the computer system
work. There are additional devices that are connected with the computer. The
devices that are used to store the output are called storage devices.
This cycle of input, process and output is called IPO cycle.
Input device
Processing device
Output device
For better understanding about the IPO cycle, consider the
example, it is like when somebody asks you a question, (input - listen/read),
you understand the meaning (process - brain comprehends the information) and
you answer to that question (output - verbal/written). This is called
Input-Process-Output (IPO) cycle. In daily life you use IPO cycle to do certain
tasks.
So, that’s
it for today. I will upload next blog as soon as possible.
Thank
You!!!
