ABSTRACT

This paper deals on what the computer is capable of, how it helps people

and things, its significance and advantages. Because of this, readers will value

computers as these are very helpful in daily living but also, will be informed on

how to deal with it correctly since all that were used without limitation can be

harmful.

INTRODUCTION

It is no doubt that computer is really helpful not only to humans but also

to others (like animals, industries, economy, etc.). In the world of technology,

computer is useful to done a work easily, smoothly, fast. Computer has made an

impact on society. It has change the angle of life. The use of computer technology

has affected every part of life. People are using a computer to perform a different

task easier. Computers are not only use for personal purpose that is mostly use

in the organizations. Computers were also used for recording data of their

customers. Bank is using computers for maintaining accounts and managing

financial transactions. They are providing facilities of online banking; customer

can check their account balance from using the internet. Different task are

performed automatically by using computers. Because of this, it reduce the

needs of people. The use of computer puts a world at a different height. But every

coin have a two side, in that way use of computer has some advantages and

disadvantages. Financial difficulties may make it difficult for some students to

access important coursework, while other students may use computers to play

game or chat. Students replace a paper and pen with a computer for education,

handwriting skills may suffer. Learners benefits from increased brain activities

when writing new information by hand, particularly in subjects such as math

and chemistry. Most computer programs include a spelling and grammar check,

and students might depend on the computer to correct spelling and grammatical

5

errors. This happens because almost anything, or should I say “everything” can

be found already on the internet.

This paper will discuss what the use of internet is all about, how it can

cause good to users, but also, how it can be a disadvantage for users.

DISCUSSION

What is an internet?

Figure 1. Meaning of Internet

The Internet has revolutionized the computer and communications world

like nothing before. The invention of the telegraph, telephone, radio, and

computer set the stage for this unprecedented integration of capabilities. The

Internet is at once a world-wide broadcasting capability, a mechanism for

information dissemination, and a medium for collaboration and interaction

between individuals and their computers without regard for geographic location.

The Internet represents one of the most successful examples of the benefits

of sustained investment and commitment to research and development of

information infrastructure. Beginning with the early research in packet

switching, the government, industry and academia have been partners in

7

evolving and deploying this exciting new technology. Today, terms like

"bleiner@computer.org" and "http://www.acm.org" trip lightly off the tongue of

the random person on the street.

This is intended to be a brief, necessarily cursory and incomplete history.

Much material currently exists about the Internet, covering history, technology,

and usage. A trip to almost any bookstore will find shelves of material written

about the Internet.

There is the technological evolution that began with early research on

packet switching and the ARPANET (and related technologies), and where

current research continues to expand the horizons of the infrastructure along

several dimensions, such as scale, performance, and higher-level functionality.

There is the operations and management aspect of a global and complex

operational infrastructure. There is the social aspect, which resulted in a broad

community of Internauts working together to create and evolve the technology.

And there is the commercialization aspect, resulting in an extremely effective

transition of research results into a broadly deployed and available information

infrastructure.

The Internet today is a widespread information infrastructure, the initial

prototype of what is often called the National (or Global or Galactic) Information

Infrastructure. Its history is complex and involves many aspects - technological,

organizational, and community. And its influence reaches not only to the

technical fields of computer communications but throughout society as we move

8

toward increasing use of online tools to accomplish electronic commerce,

information acquisition, and community operations.

The Internet is so far one of the greatest inventions of all time. The Internet

has made it possible for us to do lots of things. People can shop in online stores

like eBay, communicate with family and friends via Skype or Facebook, watch

the latest videos on YouTube, blog and make money from it, and so much more.

What are the advantages of the use of Internet?

1. Unlimited Communication

The Internet has made it easy for people to communicate with others

because it is cheap and convenient. The only costs incurred are those paid to

the Internet service provider. If you want to talk to someone who is in another

part of the globe, you can just fire up Skype or any other communication app

and hold a video chat.

Services such as Skype have helped people from geographically segmented

countries to interact and share ideas. As such, people are able to share their

thoughts and views on matters affecting the globe. The Internet acts as common

global platform where people explore ideologies and cultures without limitation.

9

Figure 2. Unlimited Communications

2. Abundant Information and Resources

The Internet is swamped with information about anything and everything.

There are multiple search engines that have made it easier for Internet users to

find information. For example, it is now common for people to look for free advice

from the Internet on all sorts of issues. The premise here is that whatever

problem you are experiencing, someone somewhere has experienced it and

probably solved it.

You can also get the latest news, breakthroughs in all fields including

medicine and even research publications at the click of a button. The Internet is

10

basically a globally accessible repository of knowledge, and the best part is

everyone gets to chip in.

Figure 3. Information Resources

3. Easy Sharing

Thanks to the Internet, sharing information is fast and seamless. If you

want to tell your 30 friends about your latest promotion, you can do so in an

instant. You can use social media sites such as Facebook or an IM app. They

will all get the news at the same time. You can also share music, videos and any

other file.

11

Figure 4. Easy Sharing

4. Online Services and E-commerce

Today it is possible to carry out financial transactions online. You can

transfer funds, pay taxes and utility bills or book movie tickets over the Internet

in the comfort of your office or home.

The growth of e-commerce has made it possible for people to shop for most

things online. This has seen the emergence of retail giants such as Amazon, Ebay

and Alibaba. They sell consumer goods globally. Such a feat was virtually

impossible before the Internet.

5. Entertainment

This is one of the major reasons why many people enjoy surfing the

Internet – entertainment. You can watch movies, listen to music, read your

favorite celebrity gossip columns and play games over the Internet. The Internet

has become a mammoth amusement park that never closes.

13

What are the disadvantages of the use of Internet?

1. Spam Mail

Spamming is the sending of unwanted and useless emails to random

people. These emails obstruct the recipient needlessly. They are illegal and can

cause frustration because they make it hard for people to access their email

accounts. Bots are used to bombard your inbox with endless advertisements.

This is quite perplexing as it always gets mixed up with important emails.

Luckily, most email service providers have a security system in place to prevent

spam emails from going to your inbox. All emails that are deemed suspicious get

their email ID or IP address blocked or sent to the Spam folder.

14

Figure 7. Spamming

2. Virus, Trojan & Other Malware

These are malicious programs that plague the Internet time and again.

They attack a computer with the sole intent of causing harm. They can make the

computer malfunction or even this can be very costly especially if you lose

important data. Worse yet is the fact that you can easily fall victim to malicious

software by clicking on a link on the Internet that appears genuine. Internet

viruses can be categorized to three types - those that harm your executable boot

files and system, those that affect a specific file by destroying it and those that

keep changing things in your computer like Word files. You can protect yourself

15

by installing a reliable anti-virus program on your computer before accessing the

Internet.

Figure 8. Viruses that are harmful to computers

3. Leakage of Private Information

The fact that the Internet has become a market place has also seen a rise

in fraud cases. Credit/debit card details are particularly vulnerable. This calls

for extreme caution when transacting online. Make sure to use a reliable

payment processor instead of sending your details directly to an individual or

business.

16

Figure 9. Absence of Privacy

10. Addiction to Internet

Just like everything else, people also get addicted to the Internet. This may

sound bizarre, but some people spend more than their fair amount of time on

the Internet. This affects their social interactions a great deal. Internet addiction

has been known to be a major cause of obesity and has, in some cases, led to

some diseases like carpal tunnel syndrome. With some help, people addicted to

the Internet can overcome this challenge.

17

Figure 10. Internet Addiction

5. Kids Exposed to Adults-Only Content

The fact that Internet has all information you could ever need is both a

good thing and a bad things. This is because it contains age-inappropriate

content like pornography. Unfortunately, such content can be accessed by

children as young as ten. All guardians and parents can do about it is lock out

harmful sites to keep their children safe. Nevertheless, this is not a full proof

strategy as children can still access the Internet from other devices.

18

Summary on Advantages and Disadvantages ofInternet:

Advantages:

1) Information on almost every subject imaginable.

2) Powerful search engines

3) Ability to do research from your home versus research libraries.

4) Information at various levels of study. Everything from scholarly articles to

ones directed at children.

5) Message boards where people can discuss ideas on any topic. Ability to get

wide range of opinions. People can find others that have a similar interest in

whatever they are interested in.

6) The internet provides the ability of emails. Free mail service to anyone in the

country.

7) Platform for products like SKYPE, which allow for holding a video conference

with anyone in the world who also has access.

8) Friendships and love connections have been made over the internet by people

involved in love/passion over similar interests.

9) Things such as Yahoo Answers and other sites where kids can have readily

available help for homework.

10) News, of all kinds is available almost instantaneously. Commentary, on that

news, from every conceivable viewpoint is also available.

19

Disadvantages:

1) There is a lot of wrong information on the internet. Anyone can post anything,

and much of it is garbage.

2) There are predators that hang out on the internet waiting to get unsuspecting

people in dangerous situations.

3) Some people are getting addicted to the internet and thus causing problems

with their interactions of friends and loved ones.

4) Pornography that can get in the hands of young children too easily.

5) Easy to waste a lot of time on the internet. You can start surfing, and then

realize far more time has passed than you realized. Internet and television

together of added to the more sedentary lifestyles of people which further

exacerbates the obesity problem.

6) Internet has a lot of "cheater" sites. People can buy essays and pass them off

as their own far more easily than they used to be able to do.

7) There are a lot of unscrupulous businesses that have sprung up on the

internet to take advantage of people.

8) Hackers can create viruses that can get into your personal computer and ruin

valuable data.

9) Hackers can use the internet for identity theft.

10) It can be quite depressing to be on the internet and realize just how

uneducated so many people have become in today's society.

20

Since there are so many information on the internet and some of it can be

edited by whoever wants to modify it, there is an instance to have wrong

information. Gathered wrong data is called as misinformation.

What is misinformation?

It is a false or inaccurate information especially that which is deliberately

intended to deceive.

How Misinformation spreads on the Internet?

1. False information and the news

Within a number of professions – journalism being an obvious one – the

spread and potential for reporting misinformation is a genuine concern. Being

first to report breaking news has long been a key value for traditional media

outlets, though this may no longer hold the appeal it once had. Some news

organisations are instead placing higher value on being right even if that means

not being first in reporting a story. This is probably a result of various high profile

mistakes made recently using social media information.

Near to the anniversary of the 2013 Boston Marathon bombings, it is worth

remembering that information posted on Reddit led to the New York Post printing

images of two suspects on its front page, who ultimately had nothing to do with

the bombings. Also, following the disappearance of Malaysia Airlines flight

MH370 in March, NBC news highlighted various false reports spreading on social

media which alleged that the plane had made a safe landing.

21

Time-consuming verification practices make it near impossible for

newsrooms to compete with the speed of social media; online verification is

increasingly important if this allows the reporting of factually correct online

information. Trust in the source of information understandably continues to be

one of the most, if not the most, important asset a news organisation has.

2. Are internet users concerned?

While the WEF data showed the rapid spread of false information as a

key trend for 2014, the 2013 Oxford Internet Survey (Pdf) found that trust in

the reliability of online information among British internet users has changed

very little in the past 10 years. More than that, and this is especially important

in relation to false information and the news, users identify the internet as the

22

most reliable source of information over television and radio (with a score of 3.6

on average, where 1 is unreliable and 5 is totally reliable).

The authors note: This stability suggests that users have learnt to what

extent they can trust information online. In this light, we can see that people

have a learned level of scepticism about information that can be found online,

which is contrary to many expectations of people being unduly influenced by

misinformation distributed online.

But even if internet users are not terribly concerned about false information, it

remains an issue.

3. How does information spread?

False information spreads just like accurate information. Important work

is being developed on the spread and circulation of online information,

specifically academic and industry studies on virality. This seeks to better

understand the circumstances under which information has or may spread.

What is clear is that it is difficult to isolate specific patterns, users or types of

content that may result in the spreading of information online.

But some patterns do emerge. In their analysis, Karine Nahon and Jeff

Hemsley found that the role of "gatekeepers" is central to whether something

goes viral or not. These gatekeepers – people who are well placed within a

23

network to share information with others – are often old-fashioned journalists or

people "in the know". Nahon and Hemsley provide the famous example of Keith

Urbahn, chief of staff for former US defense secretary Donald Rumsfeld. His

tweet reporting the death of Osama bin Laden went viral before the president

had been able to address the news media. A visualisation by Social Flow

highlights the importance of both Urbahn and CNN's Brian Stelter in the spread

of this information.

A further body of work focuses on a specific type of online content that

often spreads rapidly: internet memes. Limor Shifman defines an internet meme

as:

a) a group of digital items sharing common characteristics of content, form,

and/or stance, which b) were created with awareness of each other, and c) were

circulated, imitated and/or transformed via the internet by many users.

When it comes to memes, the idea of "false information" takes on a very

different meaning compared to how journalists may verify online information.

Take, for example, the incident of a police officer seemingly casually pepper

spraying a group of Occupy protesters at a university campus in late 2011. While

this incident did take place, it also gave birth to a popular meme. This shows the

police officer photoshopped into a series of art works as well as other

contemporary and historical settings. So while the original information is

accurate, its further treatment turns it into something else.

24

With the rapid development of platforms like Twitter, these different types

of content – and different types of users, including fake and spoof accounts – all

exist in the same place and can relate to the same event, which adds

complication.
