Information Technology A Definition:
We use the term information technology or IT to refer to an entire industry. In actuality,
information technology is the use of computers and software to manage information. In somecompanies, this is referred to as Management Information Services (or MIS) or simply as
Information Services (or IS). The information technology department of a large company
would be responsible for storing information, protecting information, processing the
information, transmitting the information as necessary, and later retrieving information as
necessary.
History of Information Technology:
In relative terms, it wasn't long ago that the Information Technology department might have
consisted of a single Computer Operator, who might be storing data on magnetic tape, and
then putting it in a box down in the basement somewhere. The history of information
technology is fascinating! Check out thesehistory of information technologyresources for
information on everything from the history of IT to electronics inventions and even the top 10
IT bugs.
Some advantages of information technology
Globalization - IT has not only brought the world closer together, but it has allowed the world's
economy to become a single interdependent system. This means that we can not only shareinformation quickly and efficiently, but we can also bring down barriers of linguistic and geographic
boundaries. The world has developed into a global village due to the help of information technology
allowing countries like Chile and Japan who are not only separated by distance but also by language
to shares ideas and information with each other.
Communication - With the help of information technology, communication has also become
cheaper, quicker, and more efficient. We can now communicate with anyone around the globe by
simply text messaging them or sending them an email for an almost instantaneous response. The
internet has also opened up face to face direct communication from different parts of the world
thanks to the helps of video conferencing.
Cost effectiveness - Information technology has helped to computerize the business process thus
streamlining businesses to make them extremely cost effective money making machines. This in turn
increases productivity which ultimately gives rise to profits that means better pay and less strenuous
working conditions.

Bridging the cultural gap - Information technology has helped to bridge the cultural gap by helping
people from different cultures to communicate with one another, and allow for the exchange of
views and ideas, thus increasing awareness and reducing prejudice.
More time - IT has made it possible for businesses to be open 24 x7 all over the globe. This means
that a business can be open anytime anywhere, making purchases from different countries easier
and more convenient. It also means that you can have your goods delivered right to your doorstep
with having to move a single muscle.
Creation of new jobs - Probably the best advantage of information technology is the creation of new
and interesting jobs. Computer programmers, Systems analyzers, Hardware and Software
developers and Web designers are just some of the many new employment opportunities created
with the help of IT.
Some disadvantages of information technology
Unemployment - While information technology may have streamlined the business process it has
also crated job redundancies, downsizing and outsourcing. This means that a lot of lower and middle
level jobs have been done away with causing more people to become unemployed.
Privacy - Though information technology may have made communication quicker, easier and moreconvenient, it has also bought along privacy issues. From cell phone signal interceptions to email
hacking, people are now worried about their once private information becoming public knowledge.
Lack of job security - Industry experts believe that the internet has made job security a big issue as
since technology keeps on changing with each day. This means that one has to be in a constant
learning mode, if he or she wishes for their job to be secure.
Dominant culture - While information technology may have made the world a global village, it has
also contributed to one culture dominating another weaker one. For example it is now argued that
US influences how most young teenagers all over the world now act, dress and behave. Languages
too have become overshadowed, with English becoming the primary mode of communication for
business and everything else.
I found this, hope it work. Some advantages and disadvantages of information technology Before
we can know about all the advantages and disadvantages of information technology, it is
essential that we know what information technology is exactly, and why it has it come to play
such a important role in our daily lives. Today information technology involves more than just

computer literacy; it also takes into account how computers work and how these computers can
further be used not just for information processing but also for communications and problem
solving tasks as well. Our world today has changed a great deal with the aid of information
technology. Things that were once done manually or by hand have now become computerized
operating systems, which simply require a single click of a mouse to get a task completed. With
the aid of IT we are not only able to stream line our business processes but we are also able toget constant information in 'real time' that is up to the minute and up to date. The significance of
IT can be seen from the fact that it has penetrated almost every aspect of our daily lives from
business to leisure and even society. Today personal PCs, cell phones, fax machines, pagers,
email and internet have all not only become an integral part of our very culture but also play an
essential role in our day to day activities. With such a wide scope for the purpose of this article
we shall focus on the impact of the internet in information technology. Some of the advantages of
information technology include: Globalization - IT has not only brought the world closer together,

Information Technology Pros
1. The world got flexibility
What we think, do or plan must be shared with our co-workers, colleagues and friends. The internet
technology has advanced this system to a great extent. The telephone idea (by Alexander Graham
Bell) has been modified and made as Cell Phones to increase more flexibility in communication and
talk to our dear fellows whenever we require!
2. The sense of responsibility has increased
Let us take Barack Obama- USA President as the figure. With the use of networking sites (Twitter
and Facebook), blogs, social bookmarking, the leader can approach to the world whenever necessary
and we can receive the news and updates which he has done (or wants to be done by us) within a
very short period.
3. Easy thinking & evolution in transportation
To think and to research, we need resources to find what our past people has thought, what quotes
they have left for us (+information + theory). We can find them by a single click in search engines
(specially Google, Yahoo!). By getting a clear cut idea, we get the chance of contributing the world
with new technological ideas and inventions and share what we have learnt throughout our lives.
And throughout the ages, it helped us to evolute the transportation strategy which helps us to visit
from a place to another by (Roads, highways, air, water and in the skies!)
4. Saves thousand of lives daily
So, by the point heading I hope you understand I am referring towards Medical Sector development.
Each day people are getting relief by the perfect use of Medicine, Hospital Technology with addition
of (X-Rays, Laser Treatments) and more on the queue. By the combination of the World Health
Organization, various fatal diseases can be overcome and just expelled from specified countries by
quick plans and ideas.
5. Increase the sense of Human Rights
The technology can remind of our human rights, basic needs and give updates where relief or
worldwide help is necessary. During earthquakes, terrible floods, while co-operation is necessary theWorld Wide Web can help us to collect the donation by a desired amount.

It is not possible to just figure out everything about the good and bad sides of Information and
Technology within a page and article as because it has mixed with every aspects and corners of our
lives. Rather, let us look at the side effects, bad sides (cons) which IT-sectors have brought to the
Human Society.
Information Technology Cons
1. It has taken away peoples Privacy
As IT-Sectors have wined the peoples heart worldwide. People are here to share and store any kind
of information, private date in their hard drives and private online databases. But due to some
Cyber-Criminals, nothing is SO Safe both online and offline. If someone becomes a bit careless, s/he
may needs to pay high for it. (Its serious).
2. The online community is not safe for Family anymore
Children under age may often share Cell Numbers, Private Email Address which can be hacked by
people and can pass it to the criminals who have a blue-print to harm the society. And people are
loosing credit card privacy and other payment processing options. Again, there are some sites
created by Nasty Guys, which can lead under eighteen teenagers to a different pathThat Is Going
To Bring Harms To The Nation.
3. It is going to damage a Humans Natural Power
We can think, gather human principles (ethical knowledge) and make co-operative relationships
between friends and families. But due to harmful aspects of (IT) people are becoming fully
technological based. And it can bring huge damage to the society as its taking away the natural
thoughts and organic ideas.
4. It can bring World Destruction without Efficient Administration
This is an extra point which I am writing by remembering various Science Fictions. Great scholars
have though about the matter wisely. Til now, we (humans) are possessing the leading place in the
world and administering the computer technology. But a day MAY come when the technology is
going to administer us in all aspects. It may probably happen that we are converted to the slaves of
Technology.
So, by this cons I am not trying to tell that Technology is here to bring harms only, because I myself is
a technological man who passes 24 hours browsing computer and talking on phones. But as a part of
human society we need to give up a look at the both sides of IT.

THE ADVANTAGE OF USING IP
IP enables cross-platform, or heterogeneous, networking. For example, a Windows NT/2000
network could contain Unix and Macintosh workstations or even networks mixed in it. TCP/IP also
has the following characteristics:
Good failure recovery
The ability to add networks without interrupting existing services
High error-rate handling
Platform independence
Low data overhead
Because IP was originally designed for Department of Defenserelated purposes, what we now call
features or characteristics were actually design requirements. The idea behind "Good Failure
Recovery" was that if a portion of the network were disabled during an incursion or attack, its
remaining pieces would still be able to function fully. Likewise is the capability of adding entire
networks without any disruption to the services already in place. The ability to handle high error
rates was built in so that if a packet of information got lost using one route, there would be a
mechanism in place to ensure that it would reach its destination using another route. Platform
independence means that the networks and clients can be Windows, Unix, Macintosh, or any other
platform or combination thereof. The reason IP is so efficient lies in its low overhead. Performance is
key for any network. IP is unmatched in its speed and simplicity.
Disadvantage of Internet Protocol
1. SYN Attacks
The Internet Protocol uses a three-way handshake system. Under this system the user contacts a
server, which then sends a response back to the user asking the user to confirm the connection. The
computer hosting the connection must then wait 75 seconds to receive a response to the
acknowledgment, to compensate for network slowdown. SYN attacks work by sending the first
request but not the second over and over again. This monopolizes the computer's resources, causing
other legitimate connections to fail.
2. SEQUENCE MANIPULATION
The Internet Protocol keeps packets of information in sequence. If a user goes offline, either by a
malicious user's designs or other means, any computers it is currently communicating with will close
the connection if a response without the proper sequence number is received. If a user intercepts
these messages he can discern the ID number and respond as the user, resulting in communication
with the machine being hijacked. This can cause theft of important data.

3. AMORPHOUS IDENTIFICATION
The Internet Protocol was designed to only allow a single connection at a time and to have this
connection be routed to a definite user. As the Internet has progressed and IP address space
becomes increasingly precious, this address space is no longer dedicated and is usually assigned
among a pool of users. This lack of unique identification makes it hard to verify a user and adds to
the complexity of an application's security by removing trust in the identity of the user.
4. DNS FLAWS
The Domain Name Service (DNS) is a way of looking up the IP address of a domain name. Internet
Protocol can only communicate to IP addresses, requiring Internet communication to occur through
a DNS server maintained by your Internet Service Provider. This flaw can be exploited by redirecting
domain names to different IP addresses.
Pros and Cons
There are many pros and cons to using cookies. Some sites use them for security, to
make sure that a user is who they say they are. Some sites have also been accused of
using cookies to track users on the web, in a way which may invade a user's privacy.
Many e-commerce sites use cookies in order to customize the way their site looks when
a user goes to it. Amazon.com, for instance, uses cookies to track a user in order to give
them recommendations, to keep track of a shopper's cart, and also to enable their "1-
Click" shopping.(8) Amazon.com's system keeps a record of a user's credit card
information, associated with the identification number on their cookie. This means thatwhen the user returns to buy something, there is no need to send their credit card
information over the Internet, potentially preventing the risk of having that information
fall into the wrong hands (9). Many other sites use a similar system to display ads or
news that are specifically tailored for the individual visitor.
Some sites have introductory pages, which are displayed for first time users, so that the
user understands what the site is about. However, it would be frustrating if every time a
visitor goes to a site they have to click through all the introductions. Cookies provide a
way around this. After a user has been through the introductory pages, a site can send a
cookie to the computer that says that the user has been there. The next time the user
arrives at the page, the site knows that they have been through the introduction, and so itcan just pass them on to the site directly. This displays how cookies can be useful for
website developers and users alike (10).
Cookies also help provide security for information exchanges. For instance, some
websites will use cookies to prevent an attack such as Session Hijacking, when an
attacker gets in between a user and a site, and assumes the identity of the user. Cookies
provide a site with a way to make sure that the computer that it's talking to is the same
computer it was talking to a minute ago. Overall, however, one of the most persistent
ways cookies are used are to provide login information for a user.
For instance, Yahoo! uses and optional cookie so that when a user who goes to the site
-
8/11/2019 IT and Its Pros and Cons
8/9
often visits the site, it "remembers" who they are, and gets the cookie information to log
them in and display their own customized page. This saves the user a little bit of time
and effort, and makes the site a more pleasant experience (11).
Advertisers are also some of the largest users of cookies. Companies like Doubleclick
use cookies to find out what users are interested in. For instance, if one goes to a lot ofsites that involve travel to London, after a while, Doubleclick can customize the ads he
or she sees, and may present one for a site that sells airline tickets, or discount luggage.
The real-world equivalent of this is shopping catalogues, which often sell information
about people who order things from them. If a consumer buys a lot of clothing from mail
order catalogues, chances are after a while he or she will start receiving more and more
catalogues to look at, because he or she have been put on a list of people who are
interested in clothing catalogues.
There are, however, many security concerns associated with cookies. One of the
shortfalls of cookies is that they are dependent on the computer on which they are
placed. Just because that computer is visiting a site again, doesn't mean it is the sameuser. This means that, in theory, if one uses a computer to visit a site which uses a cookie
to identify him or her, and then he or she walks away from that computer and someone
else visits the same site, they could get information that is actually meant for the original
user (12)
Another problem is one of privacy. Many users like the internet for its anonymity. The
idea that an individual or organization could actually be tracking where they are going
and what sites they are visiting really bothers some users. The fact that some of this
tracking information could be used for the purpose of making money, by targeting
advertising for instance, also concerns some users. There have also been incidents where
government websites are found to be using cookies. Although these cookies may not be
used to track visitors, the fact that the government could use this method to track users,
concerns many privacy activists (13).
Another concern is the fact that, not only are the web-servers keeping track of which
sites are visited, but so is the computer that the cookies are placed on. On a computer
with a cookie-enabled web browser, the browser creates a text file that keeps track of
cookies. This means that if one wanted to see what sites someone had been to on his
computer he could theoretically take a look at this file and get an idea. This is similar to
the information that is kept by the browser's history list, but in the case of cookies, the
file also may contain information like usernames, passwords, identification numbers, andeven credit card information (although it is considered extremely bad form for internet
designers to use cookies for credit cards) (14).
Cookie security is a large problem. The concern is that many security holes have been
found in different with browsers. Some of these holes were so serious that they allowed
malicious webmasters to gain access to users' email, different passwords, and credit card
information. The worry is that, even though past holes have been patched, there could be
more holes out there (15).
Some also have concerns about the whole system of cookies in the first place. The
general though is that cookies could become accessible to a website which did not issuethem. This would mean, in theory, that a malicious web site designer would be able to
-
8/11/2019 IT and Its Pros and Cons
9/9
collect not only the information which is in the cookie he gives the user, but also the
information in all of the cookies on the user's computer. While this may only be theory,
it is still very worrisome to many privacy advocates.
Many users don't even know that cookies exist because they aren't something that the
user really sees. The fact that the general public is not aware of this "threat" to theirprivacy is also a large concern for people in privacy groups. Because cookies are passed
back and forth without ever asking the user for permission, the user is never really made
aware of their existence. It is also important to note that it is possible to refuse cookies,
but the default settings for almost all web browsers allows them with no questions asked.
There are also some e-commerce sites that will not allow a user to buy something
without first turning cookies "on." (16)
Another privacy concern is the fact that some companies have figured out ways to
connect the anonymous clicks of a user to actual personal information which they have
collected. The legality of this kind of action is still being debated, which will be
discussed later. In the case of Doubleclick, the Electronic Privacy Information Centerhas filed a complaint against them alleging that they are infringing on a user's right to
privacy because of their plans to match up identification numbers found in cookies with
names and personal information of the user (17).
It is not just advertisers that worry privacy activists, but also researchers. The
information in and gathered from cookies may be used to do research on controversial
issues such as abortion and gun control. Information could be used to gather information
which will be used by special interest groups without the knowledge of the user (18).
Although there are more pros and cons involved with this issue, these above mentionedissues are at the heart of the matter. Many web site designers use cookies in ways that
benefit the user, perhaps saving the user some time or frustration. But there are also real
dangers involved in the use of cookies which make them a concern among privacy and
internet activists.
