A brief introduction to IT
Daily use of IT

Information technology (IT) is the use of any computers,
storage, networking and other physical devices,
infrastructure and processes to create, process, store,
secure and exchange all forms of electronic data.
Typically, IT is used in the context of enterprise
operations as opposed to personal or entertainment
technologies. The commercial use of IT encompasses
both computer technology and telephony.
The term information technology was coined by
the Harvard Business Review, in order to make a
distinction between purpose-built machines designed to
perform a limited scope of functions and general-
purpose computing machines that could be
programmed for various tasks.
As the IT industry evolved from the mid-20th century, it
encompassed transistors and integrated circuits --
computing capability advanced while device cost and
energy consumption fell lower, a cycle that continues
today when new technologies emerge.
For one, it allows businesses to break the boundaries
of location and language. Take, for example, a retail
store. If the store sticks to merely doing physical
transactions from its brick and mortar store, it limits
the possible clientele to the people within its location.
But by using the internet, the store can be part of a
national—and even global—marketplace. This is the
basic concept that makes websites such as eBay and
Amazon a success.
Of course, Information Technology also works in the
physical business set-up. Information Technology in
business allow companies to store product
information on virtual databases (rather than physical
ones), allowing for easier retrieval of data when
needed. It makes internal communication easier,
thanks to email, telephone linking, and other similar
methods of communication.
Students have many opportunities to learn
the basic computer skills to facilitate their
Online learning opportunities and the use
of open educational resources and other
technologies can increase educational
productivity by accelerating the rate of
learning; reducing costs associated with
instructional materials or program delivery;
and better utilizing teacher time.

Cost effectiveness - Information technology
has helped to computerize the business
process thus streamlining businesses to
make them extremely cost effective money
Bridging the cultural gap - Information
technology has helped to bridge the
cultural gap by helping people from
different cultures to communicate with one
Creation of new jobs - the best
advantage of information
technology is the creation of new
and interesting jobs.
Communication - With the help of
communication has also become
cheaper, quicker, and more
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
Unemployment - While information
technology may have streamlined the
business process it has also crated job
example- a lot of lower and middle level
jobs have been done away with causing
more people to become unemployed.
