Revolution in computer technology ?

hi

In the early twenty-first century, the computer revolution is exemplified by a personal computer linked to the Internet and the World Wide Web. Modern computing, however, is the result of the convergence of three much older technologies—office machinery, mathematical instruments, and telecommunications—all of which were well established in Europe in the twentieth century.

Office machinery was first developed in the United States in the last quarter of the nineteenth century. Office machines mitigated clerical drudgery and facilitated the systematic organization of large-scale offices.

The modern electronic computer was invented in the United States in 1946. As originally conceived, the computer was a mathematical instrument designed for the solution of numerical problems.

Electric telegraph systems were simultaneously developed in many countries around the middle of the nineteenth century.

Telegraphs were initially used for signaling on the newly built railways, but soon found a lucrative market for the transmission of news, market, and financial information. The International Telegraph Union, established in Bern, Switzerland, in 1865, created standards for the international transmission of messages. The early years of the twentieth century saw the development of national telephone systems.

The personal computer emerged as a consumer item in the late 1970s. The first machines, such as those made by Apple, Commodore, and Tandy, were imported from the United States, but European manufacturers soon entered the market producing their own designs.

The tremendous impact computers have on society. There have been four computer revolutions. The first was when computers began to proliferate in the 1960s, which transformed business around the world. The second started in the late 1970s when consumers became computer customers for the first time. Without personal computers, the Internet, the third revolution, would not have flourished.

It is a truism that computing continues to change our world. It shapes how objects are designed, what information we receive, how and where we work, and who we meet and do business with.

The following discussions are concerned with a radical change in the technology which provides components for use in digital data processing systems.

At the onset of a revolution it is not clear what the outcome may be. Technological revolutions, as opposed to political revolutions, however, tend to have a common characteristic of inducing major changes regardless of whether or not the revolution is completely successful. The papers presented in this session consider various aspects of what is being anticipated as a technological revolution.
