INTODUCTION

1. Background

A computer is a general purpose device that can be programmed

to carry out a set of arithmetic or logical operations.

The computer designed to meet the needs of people, inclduing

laptops, desktops or personal computer desktop and others.

Based on the background above, the peoples especially the

computer science's students need to know about the uses of

computers in daily life and the types of computer.

2. Problem identification

Related to the background above, there are some problems that

may arise. The writer identifies the problems as follows :

o How are computers used in everyday?

o What are the types of computer?

3. Problem limitation

In order to reach the expected goal, the writer limits the problems

with mention the uses of computer in daily life and the type of

computer.

THEORETICAL REVIEW

1. Everyday uses of computers

Computers are part of the people's everyday lives. The computers

have an effect on almost everything the peoples do. The peoples get

all the modern facilities by the invention of Computers. Right from

watching movies, listening a music, playing games, prepare office

documents, prepare daily planners to latest facilities of emailing,

chatting, video-conferencing and social interaction through networking.

Super fast computers are able to solve trillions of mathematical

problems within a fraction of a second. Earlier, calculators were

commonly used while nowadays, even complex calculation can be

done with the help of computers. It takes instruction in the form of

input and provide output results accordingly.

While calculator gives response to the immediate input only,

computer work with a set of instructions installed in it, so it constantly

works, with amazing speed.

Because of this unique, exclusive features, computers play a vital

and crucial role in modern people's lives such as Banking,

Transportation, Travelling, Security, Business, Education, Tourism,

Aviation, Government affairs, Defense, Medicine, Army, Emergency

Services (hospital), etc.

Besides the above-mentioned sectors, the computers also play a

pivotal role in daily life in the form of Eshopping. Shopping via internet

is common now-a-days. Marketing, shopping, advertising, fashion

designing, event organizing, job seeking, etc are all the latest usage of

computers. Thus it is slowly and positively dominating the lives of

mankind, being a great source of information, education and

entertainment.

3

Super computers are generally used for banking transactions, to

keep track of railways, control aircrafts, and manage

telecommunication system effectively, accurately and conveniently.

The world has become a global village due to telecommunication

system worldwide.

Uses of computers in different fields

1. Domestic

Write important documents and print them.

To Shop online

Watch Videos and play & record Music CDs, etc.

2. Commercial

Keep records of peoples pay and personal details.

View new orders over the internet and contact warehouse to

despatch them.

Collecting payments from costumers, view new stock and

calculating Pofit/loss of company.

3. Industrial

Control Factory Machines like printing presses.

Calculate stock in warehouse and automatically re-order

equitment from Main Manufacturer (like a Newspaper press

needs paper and ink).

To communicate with costumers or retail units about

dispatch details.

2. Types of computer

The electronic computers that are available nowadays vary in their

sizes and types. The computers are broadly classified into four

4

categories based on their size and type—(1) Microcomputers, (2)

Minicomputers, (3) Mainframe computers, and (4) Supercomputer.

2.1. Microcomputers

Microcomputers are small, low- cost and single-user digital

computer. They consist of CPU, input unit, output unit, storage

unit and the software.

Although microcomputers are stand-alone machines, they

can be connected together to create a network of computers

that can serve more than one user.

Microcomputers include desktop computers, notebook

computers or laptop, tablet computer, handheld computer,

smart phones and netbook.

2.1.1. Desktop Computer or Personal Computer (PC)

Desktop Computer or Personal Computer (PC) is the

most common type of microcomputer. It is a stand-alone

machine that can be placed on the desk.

Externally, it consists of three units— keyboard,

monitor, and a system unit containing the CPU, memory,

hard disk drive, etc.

It is not very expensive and is suited to the needs of

a single user at home, small business units, and

organizations.

Apple, Microsoft, HP, Dell and Lenovo are some of

the PC manufacturers.

2.1.2. Notebook Computers or Laptop

Notebook Computers or Laptop resemble a

notebook. They are portable and have all the features of

a desktop computer.

5

The advantage of the laptop is that it is small in size

(can be put inside a briefcase), can be carried anywhere,

has a battery backup and has all the functionality of the

desktop. Laptops are costlier than the desktop machines.

2.1.3. Netbook

These are smaller notebooks optimized for low

weight and low cost, and are designed for accessing

web- based applications. Netbooks deliver the

performance needed to enjoy popular activities like

streaming videos or music, emailing, Web surfing or

instant messaging.

2.1.4. Tablet Computer

Tablet Computer has features of the notebook

computer but it can accept input from a stylus or a pen

instead of the keyboard or mouse. It is a portable

computer. Tablet computer are the new kind of PCs.

2.1.5. Handheld Computer or Personal Digital Assistant

(PDA)

Handheld Computer or Personal Digital Assistant

(PDA) is a small computer that can be held on the top of

the palm. It is small in size. Instead of the keyboard, PDA

uses a pen or a stylus for input.

PDAs do not have a disk drive. They have a limited

memory and are less powerful. PDAs can be connected

to the Internet via a wireless connection. Casio and

Apple are some of the manufacturers of PDA.

2.1.6. Smart Phones

6

Smart Phones are cellular phones that function both

as a phone and as a small PC. They may use a stylus or

a pen, or may have a small keyboard. They can be

connected to the Internet wirelessly.

They are used to access the electronic-mail,

download music, play games, etc. Blackberry, Apple,

HTC, Nokia and LG are some of the manufacturers of

smart phones.

2.2. Minicomputers

Minicomputers are digital computers, generally used in

multi-user systems. They have high processing speed and high

storage capacity than the microcomputers.

The users can access the minicomputer through their PCs

or terminal. They are used for real-time applications in

industries, research centers, etc.

2.3. Mainframe computers

Mainframe computers are multi-user, multi-programming

and high performance computers. They operate at a very high

speed, have very large storage capacity and can handle the

workload of many users.

Mainframe computers are large and powerful systems

generally used in centralized databases. The user accesses the

mainframe computer via a terminal that may be a dumb

terminal, an intelligent terminal or a PC.

Mainframe computers are used in organizations like banks

or companies, where many people require frequent access to

the same data.

2.4. Supercomputers

Supercomputers are the fastest and the most expensive

machines. They have high processing speed compared to other

computers.

7

Some of the faster supercomputers can perform trillions of

calculations per second. Supercomputers are built by

interconnecting thousands of processors that can work in

parallel.

Supercomputers are used for highly calculation-intensive

tasks, such as weather forecasting, climate research (global

warming), molecular research, biological research, nuclear

research and aircraft design. They are also used in major

universities, military agencies and scientific research

laboratories.

UNIT 3

CLOSING

1. Conclusion

Computers have an effect on almost everything the peoples do,

in differ places and differ activities in their lives. Such as banking,

transportation, travelling, security, business, education, entertainment,

government affairs, defense, medicine, army, marketing, etc.

The computers are broadly classified into four categories based

on their size and type, Microcomputers, Minicomputers, Mainframe

computers, and Supercomputer. Microcomputers include desktop

computers, notebook computers or laptop, tablet computer, handheld

computer, smart phones and netbook.

2. Suggestions

The authors are aware that this paper is still far from perfect.

Therefore, the authors expect criticism and suggestions especially

about the theoretical review and formats of this paper. Finally, the

writer hopes this paper could be useful to the peoples especially for

the students of computer science.
