Converged device

This article describe science and technology convergence, with illustrations to convergence of emerging technologies (NBIC, nano-, bio-, info- and cognitive technologies) and convergence of media technology.

"Convergence is a deep integration of knowledge, tools, and all relevant activities of human activity to allow society to answer new questions, to create new competencies and technologies, and overall to change the respective physical or social ecosystem. Such changes in the respective ecosystem open new trends, pathways, and opportunities in the following divergent phase of the process" (Roco 2002, Bainbridge and Roco 2016 ).

Siddhartha Menon defines convergence, in his Policy initiative Dilemmas on Media Covergence: A Cross National Perspective, as integration and digitalization. Integration, here, is defined as "a process of transformation measure by the degree to which diverse media such as phone, data broadcast and information technology infrastructures are combined into a single seamless all purpose network architecture platform". Digitalization is not so much defined by its physical infrastructure, but by the content or the medium. Jan van Dijk suggests that "digitalization means breaking down signals into bytes consisting of ones and zeros". Convergence is defined by Blackman, 1998, as a trend in the evolution of technology services and industry structures. Convergence is later defined more specifically as the coming together of telecommunications, computing and broadcasting into a single digital bit-stream. Mueller stands against the statement that convergence is really a takeover of all forms of media by one technology: digital computers.

Media technological convergence is the tendency that as technology changes, different technological system sometimes evolve toward performing similar tasks. Digital convergence refers to the convergence of four industries into one conglomerate, ITTCE (Information Technologies, Telecommunication, Consumer Electronics, and Entertainment). Previously separate technologies such as voice (and telephony features), data (and productivity applications), and video can now share resources and interact with each other synergistically. Telecommunications convergence (also called "network convergence") describes emerging telecommunications technologies, and network architecture used to migrate multiple communications services into a single network. Specifically this involves the converging of previously distinct media such as telephony and data communications into common interfaces on single devices, such as most smart phones can make phone calls and search the web.
