ICT: Evolution and Development
ICT (information and communications technology or technologies) is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and internet network, hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing, distance learning, E-voting, electronic commerce and do on.
Military imperatives (political background) behind the development of new technologyMany of the major research and development were actually led by the military might and imperial ambition including several recent innovations in transport and communication. For example, development of Jet engine took place during the Second World War and the Korean conflict in 1950s. Communication satellites and major advances in GIS/GPS own much to the cold war after Soviet Union launched Sputnik in 1957and entered into the era of space race with its rival super power USA. The origin of computing also has its root in wartime research and development, including German Z3 projects. Internet itself has significant military origin.
Internet Revolution: How and why Internet network has grown over time
What is Internet?
A worldwide computer network that can be accessed using computer, mobile telephone, digital TV, etc. The Internet access service can be provided through a fixed (wired) or mobile network: analogue dial-up modem or standard telephone line, ISDN (Integrated Services Digital Network), DSL (Digital Subscriber Line) or ADSL, Cable modem, High speed leased lines, Fiber, Power line, Satellite broadband network, WiMAX, CDMA, Mobile broadband network and so on.
The Internet has revolutionized the field of communication like nothing before. The Internet is a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals through their computers without regard for geographic location. Internet is a widespread information infrastructure, the initial prototype of what is often called Galactic Information Infrastructure. The technological evolution began with early research on packet switching and the ARPANET while the current research continues to expand the horizons of the infrastructure along several dimensions, such as scale, performance, and higher-level functionality
