In simple words Information Technology can be described as the solutions used to manage data, information and knowledge, the Industry that provides solutions around those solutions, and the organizations, within companies, that are made up of the IT professionals that come from that industry. But in a complicated sense, it is the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information by a microelectronics-based combination of computing and telecommunications. Some of the modern and emerging fields of Information technology are next generation web technologies, bioinformatics, cloud computing, global information systems, large scale knowledge bases, etc.
WHAT IS INFORMATION AND TECHNOLOGY?
Informations are data, which are processed by computer as per requirement of the user. And, Technology is the making, usage, and knowledge of tools, machines, techniques, crafts, systems or methods of organization in order to solve a problem or perform a specific function. Together they form IT(information technology). IT is the area of managing technology and spans wide variety of areas that include but are not limited to things such as processes, computer software, information systems, computer hardware, programming languages, and data constructs. In short, anything that renders data, information or perceived knowledge in any visual format whatsoever, via any multimedia distribution mechanism, is considered part of the IT domain. IT provides businesses with four sets of core services to help execute the business strategy which are business process automation, providing information, connecting with customers, and productivity tools. In the 1960s and 1970s, the term information technology (IT) was a little known phrase that was used by those who worked in places like banks and hospitals to describe the processes they used to store information. With the paradigm shift to computing technology and "paperless" workplaces, information technology has come to be a household phrase. It defines an industry that uses computers, networking, software programming, and other equipment and processes to store, process, retrieve, transmit, and protect information. Great technological advances have been made since the days when computers were huge pieces of equipment that were stored in big, air conditioned rooms, getting their information from punch cards. The information technology industry has turned out to be a huge employer of people worldwide, as the focus shifts in some nations from manufacturing to service industries. It is a field where the barrier to entry is generally much lower than that of manufacturing, for example. In the current business environment, being proficient in computers is often a necessity for those who want to compete in the workplace. HISTORICAL BACKGROUND OF INFORMATION TECHNOLOGY:
When the terminology 'information technology' is used, mistakenly it describes the entire industry. Information technology basically refers to the employment of computer hardware and software applications to manage data. The back-story of information technology precedes the invention of the computer. The abacus, used by Asians, Egyptians, Romans, and the Greek can be termed a source of information technology. Calculators, the first mechanical one built by German polymath Wilhelm Schickard, or the slide rule, developed in 1622 by William Oughtred, also comes under the heading of information technology. Another example would be punch card machines, expanded upon by IBM in the early to mid 1900's, qualifies the term information technology. As time progress along with the advances of inventions and applied knowledge, computing took shape and became useful in a variety of ways other than calculations. Through ages, different computers were made. These were very big in size, made a lot of sound, generated a lot of heat and above all, they were very slow....
