Looking at the present scenario, one can easily predict the dominance of Information Technology in daily life. Despite of hectic schedules and lots of burdens, IT always wins in the long run. Globalization and Liberalization has expanded their wings in the world and even beyond that in terms of bringing the global space on to a common platform. Ranging from magnificent infrastructures to wearable transmitters, IT manages it all. On the contrary, there are negation points of the same for different cases. A brief research has been portrayed in this article.
Just as chemical or metallurgical or electrical technologies enable the processing of raw materials into usable goods, to satisfy man’s and societies’ needs so does information technology (IT) help the storage, processing, transmission and exploitation of information to satisfy a person’s, company’s, society’s or government’s needs for information. The invention of printing was the first big breakthrough in Information Technology. It enabled literacy and education to go up from 10% to over 80% within 50 years by making available vast amount of reading material. That reading also led to the Reformation in Europe. Other break-through for Information Technology were the inventions like telegraphy, telephony, wireless or radio, television, broadcasting, computers (from room size to desk top to lap top to palm top and very soon, wearable ones.)
There had been breath-taking inventions in electronics and photonics, micro-miniaturization, super and mega-scale integration; optical fiber and communication satellite transmissions, electronification and digitization of all information, storage and display devices and the transport of electronified information on worldwide telecommunication networks, increasingly under the control of the sender and the receiver. Information covers voice as in telephony, text as in fax, images as in video and data as between computers. The limitation for transmission and reception of information only from instruments connected to wires and therefore only from particular places, has been dramatically overcome by earth-based cellular mobile, radio telecoms and now by satellite based globe wide mobile systems like the Iridium.
Information Technology devices like microprocessors are becoming mass appliances from pace makers for the heart, hearing aids, and efficiency enhancers in automobile engines and devices to steer space vehicles on the moon.
