Information Age
From Free net encyclopedia
Information Age is a name given to a period after the industrial age. Information Age is a term applied to the period where movement of information became faster than physical movement, more narrowly applying to the 1980s or 1990s onward. One could argue, though, that it actually began during the latter half of the 19th Century with the invention of the telephone and Telegraphy. It is often used in conjunction with the term post-industrial society.

Early Information Age
Information processing
In 1837 Samuel Morse created a device which converted physical movement into electrical impulses that could travel over large distances. In 1844, telegraphy was used to transmit data along an experimental telegraph line from Washington, DC to Baltimore, Maryland. Slightly more than 20 years later, the first telegraph cables were stretched across the Atlantic Ocean, in 1858, but failed to stay in operation; however, uninterupted service began in 1866.
This invention set off a stream of devices used for the processing of information, the typewriter, the mechanical calculator, and finally, the telephone in 1876. "Informationalization" of previous devices occurred, such as the player piano.
The ability to distribute large runs of printed material had created the means for information transmission to change economic and social behavior. Telephones and ticker tape machines would be part of the infrastructure for the growth of stock markets, as well as the ability to trade precious metals, such as gold. It was the telegraph that allowed the news of Krakatoa's explosive eruption to spread around the world rapidly.
Recording added a new means of distribution: namely that of sound. However, the distribution was either person to person, as in the telegraph, or through the distribution of a physical object. Since atoms are thousands of times heavier than electrons, the next stage of information technology was to be able to transmit pure information, as the telegraph did, but with mass reception.
Broadcasting
The information technologies of the 19th century allowed faster and wider dissemination of information than previously possible. However, ultimately such information had to be reduced to the same form which had been the final form for centuries: paper, whose analogs go back to stone and clay tablets. With the development of what was called wireless transmission, when combined with the ability to transmit voice and sound from the telephone, and recording technology, a new medium began to be born, which placed a different final result in the hands of the individual. These technologies would eventually become radio.
Television followed, allowing video to be displayed with sound. While radio brought the world's events to our homes, it was television that brought the first pictures of the world to many people. TVs were first used as a way to get information and news from other places, but quickly became a very important entertainment device, as well as a useful tool for learning. Unlike radio, television brought with it a whole new industry of content delivery, mainly Cable television providers. Not only were stations producing and broadcasting their own shows, but the broadcasting industry allowed homes to receive more and more channels. With the later advances in technology, satellite television provided the most diverse content anyone could want.
Information technology
With recording technologies, with transmission, and with early computers, it didn't take very long for scientific advances to merge everything together. Information technology is the use of technology to enhance the speed and the efficiency of the transfer of information.
At first, computers were big, costly, and available only to universities and big corporations. Before the 1990s, most discoveries in information technology were driven by full time researchers having access to the high priced equipment. In the late 1980s however, small computers started to become available, such as the early Apple Computer systems, and Personal computers. International Business Machines Corporation (IBM) developed the first open standard Personal Computer (IBM PC launched in US markets 1981 first deliveries to European markets 1982 and 1983), which standardized the software developement. For the first time in the world history we had PC's that used the similar operating systems that allowed the computers users to communicate by using the same platform. IT-industry was revolutionized.
Soon after, we saw the birth of what we know as current information technology: personal computers in our own homes, using communication devices known as modems, to access information on remote servers. The first incarnation of those were BBS servers, setup by education facilities or even individual people, to store both information and allow discussion with chat and messages.
The Personal Computer
A personal computer or PC is generally a microcomputer intended to be used by one person at a time, and suitable for general purpose tasks such as word processing, programming, editing or personal computer game, usually used to run purchased or other software not written by the user. Unlike minicomputers, a personal computer is often owned by the person using it, indicating a low cost of purchase and simplicity of operation. The user of a modern personal computer may have significant knowledge of the operating environment and application programs, but is not necessarily interested in programming nor even able to write programs for the computer.
The Internet
The Internet was originally conceived as a distributed, fail-proof network that could connect computers together and be resistant to any point of failure. It was created mainly by DARPA; its initial software applications were email and computer file transfer.
With the invention of the World Wide Web, the Internet really took off as a global network. Now, the Internet is the ultimate place to accelerate the flow of relevant information.
The information age continues to this day, and technological advances such as mobile phones, high speed connections, Voice Over IP, and many more, our lives are forever changed from what it used to be, no more than 10 years ago.
The Digital Revolution
The Digital Revolution is a recent term describing the effects of the rapid drop in cost and rapid expansion of power of digital devices such as computers and telecommunications (e.g mobile phones). It includes changes in technology and society, and is often specifically used to refer to the controversies that occur as these technologies are widely adopted.
