What is IT ?
Information technology (IT) is the application of computers andtelecommunications equipment to store, retrieve, transmit and manipulate data,often in the context of a business or other enterprise. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several industries are associated with information technology, including computer hardware, software, electronics,semiconductors, internet, telecom equipment, e-commerce and computer services.

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; authorsHarold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs.

Based on the storage and processing technologies 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 (1940–present).^[5] This article focuses on the most recent period (electronic), which began in about 1940.

Future vision of IT

Information technology is a highly important aspect today. Having the ability to transfer data, store data and keep it safe is crucial in many ways. Without information technology many medical facilities and corporations would find it difficult to keep information stored securely.

Computers allow users to communicate with many people at once or in far away places. It stands to reason that will the development of better technology yearly, computers will play a vital role in the ongoing support of information technology in the future.

Computers allow users now to do many things such as writing much faster than a traditional typewriter or pen and paper would do. They also make it very possible to keep track of people, conduct business globally much easier than before and organize and store multiple files.

They also make education possible from remote locations and provide

communication that far outreaches what a traditional telephone could ever do. Of course the human brain is far more advanced than a typical home computer.

Our brains allow us to keep track of things as well and to remember faces and names, find entertainment, love others and enjoy the simpler things in life.

The future of information technology may very well involve using computers to enhance the human brain. Common computers are expected to possess the same or nearly the same capabilities as the human brain in the future.

In another twenty five years or so it may be very likely that you will be able to have a computer that will possess the ability to feel emotions and have spiritual experiences. Of course this prediction will be met with skepticism as all others have been in the past.

The first gasoline powered vehicle was met with much scrutiny as was the first airplane. Society as a whole does not generally accept things that it can not understand or control. Believing that scientific technology can produce a computer that is capable of human emotion is so far-fetched that many simply will have to see it to believe it.

Career in IT

1. 
   1
   Discover if you are already skilled in IT. If you have a PC and use it for more than just typing and basic office work, doing homework, playing games and casually browsing the web, then you have the right stuff for the job.
2. 
   
3. 
   2
   Make a list of what types of IT work you might be interested in. For example, if you love computer games, you can list "game testing," or "writing game software." If you enjoy designing, "graphic design" or "software design" should go on your list. If you are interested in how the internet works and how computer connect to each other, "network administration or network design" will work for you.
4. 
   3
   Choose something that will make you happy. If you really enjoy it as a pastime, you will progress in the skill much faster.
5. 
   4
   Get to know the right people. Many IT gurus love to assist people. Look into a formal or even casual apprenticeship. Make a geek your new best friend.
6. 
   5
   Search for educational opportunities in your area or online, and determine what the entry requirements are for each field of study. Make comparisons.
7. 
   6
   Supplement self-taught skills with a few classes or an associate degree, and move right into the job market. The more education you get in the field, the better your income will probably be in the long run, but there are entry level jobs even for people with little education.
