2. Introduction.
Information technology (IT) is concerned with the development,
management, and use of computer-based information systems.
Humans have been storing, retrieving, manipulating and
communicating information since
the Sumerians in Mesopotamia developed writing in about
3000 BC, but the term "information technology" in its modern
sense first appeared in a 1958 article published in the Harvard
Business Review; authors Leavitt and Whisler commented that
"the new technology does not yet have a single established
name.We shall call it information technology (IT). Based on the
storage and processing technology employed, it is possible to
distinguish four distinct phases of IT development: pre-
mechanical (3000 BC – 1450 AD), mechanical (1450–1840),
electromechanical (1840–1940) and electronic.This article
focuses on the latter of those periods, which began in about
1940.
3. Definition.
The InformationTechnology
Association of America has defined
information technology (IT) as "the
study, design, development,
application, implementation, support
or management of computer-based
information systems", but the term
has also been applied more narrowly
to describe a branch of engineering
dealing with the use of computers and
telecommunications equipment to
store, retrieve, transmit and
manipulate data.Although commonly
used to refer to computers and
computer networks, IT encompasses
other information-distribution
technologies such as television and
telephones, a wider field more
explicitly known as information and
communications technology.
4. Abstract.
First, the society in the developed countries will be divided into two
major groups: On the one hand,there will be technophile people,
who embrace the new possibilities which InformationTechnology
offers to their lives. On the other hand, there will be technophobic
people, who will obstruct the inroads of InformationTechnology
into their daily lives. Contrary to what most people would think,
this part of the population will not only consist of ecologists, but
also of conservative people who see technology as something
unnatural for humanity, people who don’t immediately profit from
technological progress such as the rural population and people who
are simply overwhelmed by the new technologies and cannot keep
up with the pace anymore.This group of technophobic people has
a potential to grow temporarily to at most 25% of the total
population.
8. Information Technology is defined as the use of
computers and software to manage information. In
some companies, it can be called Management
Information Services (MIS) or Information
Services (IS). The information
technology department of a large company is
responsible for storing information, protecting
information, processing the information,
transmitting the information, and later
retrieving information if needed. Around 1980,
computers with integrated circuits on a single
chip started to become available as an
affordable item, specifically designed for use
by consumers. The first IBM (News -Alert) PC
was released in 1981.
9. Graphical User Interfaces (GUIs), which are the
programs that enable users to look at screens
with windows, clickable commands and color—
appeared in the late 1980s. Windows was
introduced in 1983, while the first Apple
Macintosh came on the market in 1984.
Fifteen years ago, a computer with 24 megabytes
of random access memory (RAM (News -Alert)) was
great amount of memory. Currently, most new
computers boast a memory of one gigabyte – which
is an increase of over forty times.
10. Information technology has also shifted from
focusing on single computers to networks of
computers, as the years have passed and
technology has advanced. Networked computers
allow many different users to have access to
common databases, which has allowed databases to
be where most business records for big companies
are held. Software that implements these
databases has quickly become a billion-dollar
industry. Customer Relationship Management (CRM)
software drives business activities for many
large enterprises who sells products across the
world.
11. Information technology has brought us the
Internet. The web has quickly grown to become a
primary choice in order for people to
communicate whether it be through email or
instant messaging services. The Internet also
works as an advertising platform for millions of
businesses around the globe.
Information technology has made banking online a
reality. So much time was once spent on daily
trips to the bank, but now via the Internet
people can keep tabs on all their bank
transactions with the click of a mouse.
Some big companies in the IT industry are
Microsoft, IBM, Intel, Cisco,
Apple, Dell (News -Alert), Hp, Toshiba and
Compaq.
13. Advantages of IT.
Made our lives Easier.
Decreased Manual work.
Word processing quicker
and easier.
Social/ Communication .
Education.
Meet more friends.
Improved communication
using email, social
networking.
Quicker communication .
14. Disadvantages of IT.
Unemployment .
Privacy .
Lack of job security.
Dominant culture.
Primitive societies.
More people are
starving .
Less face to face
communication.
More chance of
bullying. Cyber stalking.
17. Benefits of IT (Information Technology)
in Modern Day Business.
Business has become very competitive.
Improve infrastructure performance .
Improve internal and Externally, operating efficiency and
quality.
Purchases from different countries easier and more
convenient.
Increasing awareness and reducing prejudice.
Helped to make communication cheaper, quicker, and more
efficient
18. Technological research has to pay attention in the sense that
there can be no advance in technical areas without considering the
social impacts an innovation has. As has been shown, not all
developments will be received with pleasure by all people, but
they are a force to be reckoned with when releasing new
technologies. Researchers have to try and make technology fit as
seamlessly as possible into the lives of humans.IT should be seen
as something useful and not as a necessary evil otherwise
researchers may end up as scapegoats for a significant part of the
population. Having said that, when looking at the market today,
there are already some technologies which were badly accepted
by the population, such as the WAP (Wireless Application
Protocol) services.The people simply didn’t see the benefit
behind.This time it was the mistake of marketing people, but it is
foreseeable that technologies will fail in the future because they
are not accepted by the population for social reasons.
