Information And Communication Technologies Of History

There are a few milestones of technological development significantly contribute to the development of ICT Untill now. First, the findings of telephone by Alexander Graham Bell in 1875. The findings are then developed into communication with the wired network provision covering the entire continent of America, even then followed by the installation of transatlantic communications cable.  

The telephone network is a massive infrastructure built first humans to global communication. Entering the 20th century, precisely between the years 1910 to 1920, realized a wireless voice transmission through the first AM radio broadcasts. Wireless voice communications is growing rapidly too soon. Then followed by an audio-visual transmission without wires, in the form of television broadcasts in the 1940s. The first operational electronic computer in 1943. Then followed by a stage of miniaturization of electronic components through the invention of the transistor in 1947 and the integrated circuit (integrated electronics) in 1957. The development of electronic technology, which is the forerunner of the current ICT, get golden moments in the Cold War era. Science and technology competition between the Western bloc (United States) and Eastern Bloc (former Soviet Union) actually spur the development of electronic technology through the efforts of miniaturization of electronic circuits for controlling spacecraft and the machines of war. Miniaturization of electronic components, through the creation of an integrated circuit, the microprocessor birth peak. Microprocessor that is the 'brain' of the computer hardware and continues to evolve to this day. Telecommunications equipment rapidly expanding digital technology replaces analog technology into use. Analog technology begun to show the limits of the maximum pengeksplorasiannya. Digitalization of telecommunications equipment and then converging with computer equipment from the beginning is a device which adopt digital technology. This convergence products that currently appear in the form of mobile phones. In the telecommunications and computing infrastructure is the content of the content (content) in the form of multimedia to get the right place to thrive. Convergence of telecommunications - is multimedia computing that characterizes the 21st century, as the 18th century is characterized by the industrial revolution. When the industrial revolution made the machines instead of 'muscle' man, the digital revolution (due to the convergence of telecommunications - multimedia computing occurs through the implementation of digital technology) creates machines that replace (or at least improve) the 'brains' man.
