ABSTRACT
This paper deals on what the computer application is, how it works on a
computer, its significance and different samples. Because of this, readers will
value applications that they have already and will be inspired to download more
of it to maximize the usage of a computer.

INTRODUCTION
A computer would be useless if it does not contain any applications. This
applications are known as software which are installed to computers for further
functions. Software manages the availability of network-centered applications
within an organization, such as e-mail, intranets and client/server. It monitors
all the components of an application to see if they are up and running. It also
checks the traffic load on essential components in order to forecast delays as
well as invoke additional processes to handle the overload if possible. It is the
applications that a software tries to manage, which in turn, serve to be an
integral component of a computer. Without an application, computer will run
but will not be functional.
This paper will discuss what this application is all about, how it is said
that through applications, a computer can be functional.

DISCUSSION
What is an application?
App is a common term for an application, especially for simple applications
that can be downloaded inexpensively or even for free. Many apps are also
available for mobile devices and even some TVs.
An app is a type of software that allows you to perform specific tasks.
Applications for desktop or laptop computers are sometimes called desktop
applications, while those for mobile devices are called mobile apps.
When you open an application, it runs inside the operating system until
you close it. Most of the time, you will have more than one application open at
the same time, which is known as multi-tasking.

Types of Apps
1. Desktop Applications- applications used in personal computers
a. Word processors: A word processor allows you to write a letter, design
a flyer, and create many other types of documents. The most well-known word
processor is Microsoft Word.

b. Web browsers: A web browser is the tool you use to access the Internet.
Most computers come with a web browser pre-installed, but you can also
download a different one if you prefer. Examples of browsers include Internet
Explorer, Mozilla Firefox, Google Chrome, and Safari.

c. Media players: If you want to listen to MP3s or watch movies you've
downloaded, you'll need to use a media player. Windows Media Player and iTunes
are popular media players.

d. Games: There are many types of games you can play on your computer.
They range from card games like Solitaire to action games like Halo. Many action
games require a lot of computing power, so they may not work unless you have
a newer computer.

e. Business: A computer has high speed of calculation, diligence, accuracy,
reliability, or versatility which made it an integrated part in all business
organisations.

Computer is used in business organisations for:
Payroll calculations
Budgeting
Sales analysis
Financial forecasting
Managing employees database
Maintenance of stocks etc.

f. Education
The computer has provided a lot of facilities in the education system.
The computer provides a tool in the education system known as CBE
(Computer Based Education). CBE involves control, delivery, and
evaluation of learning.
The computer education is rapidly increasing the graph of number of
computer students.
There are number of methods in which educational institutions can use
computer to educate the students.
It is used to prepare a database about performance of a student and
analysis is carried out on this basis.

g. Health Care Services
Computers have become important part in hospitals, labs, and dispensaries. The
computers are being used in hospitals to keep the record of patients and
medicines.
Image 6. Computers on Health
Some major fields of health care in which computers are used are:
Diagnostic System - Computers are used to collect data and identify cause
of illness.
Lab-diagnostic System - All tests can be done and reports are prepared by
computer.
Patient Monitoring System - These are used to check patient's signs for
abnormality such as in Cardiac Arrest, ECG etc.
12
Pharma Information System - Computer checks Drug-Labels, Expiry
dates, harmful drug’s side effects etc.
Surgery : Nowadays, computers are also used in performing surgery.
h. Engineering: One of major application used is CAD (Computer aided design).
That provides creation and modification of images.
Image 7. Computer in Engineering
Some fields are:
Structural Engineering - Requires stress and strain analysis for design of
Ships, Buildings, Budgets, Airplanes etc.
Industrial Engineering - Computers deal with design, implementation and
improvement of integrated systems of people, materials and equipment.
13
Architectural Engineering - Computers help in planning towns, designing
buildings, determining a range of buildings on a site using both 2D and
3D drawings.
2. Mobile Applications- desktop and laptop computers aren't the only devices
that can run applications. You can also download apps for mobile devices like
smartphones and tablets. Here are a few examples of mobile apps.
a. Gmail: You can use the Gmail app to easily view and send emails from
your mobile device. It's available for Android and iOS devices.

14
b. Social networking apps: You can use these apps to quickly share photos
with your friends and family and also to communicate with them. It's available
for Android and iOS. (Examples: Instagram, Facebook, Viber, Tango, etc.)

A computer application is defined as a set of procedures, instructions and
programs designed to change and improve the state of a computer's hardware.
Applications are made in a machine-understandable language to accomplish a
variety of individual or organizational jobs. They are made with user-friendly
interfaces for easy use.

Image 10. Applications Software
An application is any program, or group of programs, that is designed for the
end user. Application software can be divided into two general classes: systems
software and applications software. Applications software (also called end-user
programs) include such things as database programs, word processors, Web
browsers and spreadsheets. Applications are either sold, licensed, run online or
require installation on the computer. Some systems can be downloaded as
freeware, used and copied without restraint. Those that are shareware are
downloadable, but a user often needs to pay a certain amount to be able to use
them. Because of this, applications made the computer functional.
16
Every computer and mobile device will come with some applications already
built in, such as a web browser and media player. However, you can also
purchase and install new apps to add more functionality. You can review our
lessons on Installing Software on Your Windows PC, Installing Software on Your
Mac, and Free Software to learn more.
