Evolution of ICT
We cannot live in isolation. We need to interact and communicate with each other and with our surroundings. In the ancient times people used smoke signals, drum sounds, pigeons and messengers as modes of communication. These were relatively slow, unreliable and sometimes unsafe means of communication. With the advent of new technologies, the modes and methods of communication are changing very fast. Radio, television, computers, telephones, smartphones, digital camera, laptop and interactive board have revolutionised the ways of communication. These are very fast and can link distant locations within no time. We can easily send messages across the globe and learn about events all over the world in a blink of eye. Numerous technological tools have come up which help us not only to communicate but to create, store and manage information. The diverse set of technological tools and resources used to store, manage, manipulate, create and communicate digital information come under information and communication technologies (ICTs).
