Stands for "Information Technology," and is pronounced "I.T." It refers to anything related to computing technology, such as networking, hardware, software, the Internet, or the people that work with these technologies. Many companies now have IT departments for managing the computers, networks, and other technical areas of their businesses. IT jobs include computer programming, network administration, computer engineering, Web development, technical support, and many other related occupations. Since we live in the "information age," information technology has become a part of our everyday lives. That means the term "IT," already highly overused, is here to stay. Definion

Premechanical The premechanical age is the earliest age of information technology. It can be defined as the time between 3000B.C. and 1450A.D. We are talking about a long time ago. When humans first started communicating they would try to use language or simple picture drawings known as petroglyths which were usually carved in rock. Early alphabets were developed such as the Phoenician alphabet Mechanical The mechanical age is when we first start to see connections between our current technology and its ancestors. The mechanical age can be defined as the time between 1450 and A lot of new technologies are developed in this era as there is a large explosion in interest with this area. Blaise Pascal invented the Pascaline which was a very popular mechanical computer. History

Electromechanical Now we are finally getting close to some technologies that resemble our modern-day technology. The electromechanical age can be defined as the time between 1840 and These are the beginnings of telecommunication. The telegraph was created in the early 1800s. Morse code was created by Samuel Morse in The telephone (one of the most popular forms of communication ever) was created by Alexander Graham Bell in The first radio developed by Guglielmo Marconi in All of these were extremely crucial emerging technologies that led to big advances in the information technology field. Electronic The electronic age is wha we currently live in. It can be defined as the time between 1940 and right now. The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems. This computer was designed to be used by the U.S. Army for artillery firing tables. This machine was even bigger than the Mark 1 taking up 680 square feet and weighing 30 tons - HUGE. It mainly used vacuum tubes to do its calculations.

Information technology offers a nice boost for businesses of all sizes. marketing, social media, and mobile devices are just three forms of tech that can benefit virtually any organization irrespective of number of employees or bank account. However, there is some IT out there that looks like it was specially crafted for small businesses. This is technology larger companies are typically beyond having a need for.

The IT revolution drives the extraordinarily rapid decline in the cost and rapid increase in the processing power of digital technologies. The digital device whose technological advance has perhaps been most crucial to the IT revolution is the microprocessor, the collections of millions of tiny circuits that serve as the “brains” of personal computers and that are embedded in an ever-expanding number of products, from video games, to cars, to refrigerators. Rapid advancements in fiber optic technologies have also been critical to the IT revolution. Fiber optics technology enables data, including voices captured in digital form, to be converted into tiny pulses of light and then transmitted at high speeds through glass fibers wrapped into large capacity telecommunication cables.
