Evolution of Information TechnologyIn simple words ‘IT’ means collection, storage, dissimilation and use of information. Not confined to hardware & software but acknowledgement of importance of man & the goals he sets to the technology. Data leads to information, information leads to knowledge, knowledge leads to wisdom, & wisdom is the key to existence of human civilizations. Our need of accuracy & revolution towards processing of information has led us to ‘Information Revolution’. Computers and IT tools can take humans to the peak of new millennium or destroy human civilization. Technological aspects of IT: Enabling Technologies: Enabling a. Data Generation Basis of Enabling technologies: • A Global information infrastructure: Basis is to create information channel i.e. information can move to one-another; information distribution • A national information infrastructure & static information infrastructure as natural corollaries to JIT (Just In Time), can be developed in integrated manner. • Information superhighways comprise of satellite links, optical fibre links, microwave networks (3G/4G networks), telephone lines, communication modes (internet modes), cellular phone stations, VSAT terminals. • Most common hardware in the users premises is a PC with multimedia technology & associated communicator links. • Operational & Application Software: In a nutshell, system of information to behave in certain manner is necessary. Major Technologies evolved in the entire activity: i) Data Processing & storage by computers. In the form of silicon based IC (integrated circuit) technology. ii) Communication technology: Optical fibre communication resulting fibre optic link around the globe. iii) Memory technologies – Laser disc & CD-ROM. iv) Display technologies – LCD & digital. ii) Communication Technology: Main thrust to it came from development of computer technology and defense requirements. One would wonder that backbone of today IT, the internet was started as small project (ARPANET) to communicate within the defense requirements in 1970s. Optical fibre technology in communication is used today so that information must not be lost even to a smaller extent. Satellite technology & internet use has been wide spread. iii) Memory Technology: This technology is related to improvement of communication technology. This technology has been broadly divided into two parts: (a) Toroidal memory & semiconductor memory. - Saakshi Grover
