Evolution of information technology

Information Science Now you know about information technology, you might be wondering: what is information science?

With good systems engineering, older technologies can be phased out, current ones upgraded, and entirely new ones introduced, all in ways that are synergistic with the embedded base.

Today the limit is almost 1 million components on a chip; byit will be at least 5 million; and by the yearbetween 10 and million. Clearly, this force will continue to be a major spur to further progress in the information technologies.

Today applications, data and services are distributed.

C programmers specializing in network applications would not be considered for jobs writing database applications. Cloud computing enables on-demand and convenient network access to a shared pool of computing devices such as applications, networks, servers, storage and services that can be established quickly and released with minimal management effort or service provider interactions.

But it desperately needs an improvement in programming productivity to sustain both the growth in complexity and the increasing demand for software systems.

This issue ascribes to the resource crunch that we are facing. The impact of AI will be huge on the IT market in impending years.

This progress will make possible increasingly powerful, reliable, lower- cost digital systems and much more flexible approaches to systems design. According to the Merriam-Webster Dictionary, information science dates back to , and so that term has been in usage for longer than the term information technology. Computers were mostly mainframes and minicomputers. Stimulated by these and other spurts of rapid growth, the percentage of information workers in the U. Computers existed before , but they were mainly used to perform complicated calculations. The circuitry on that chip is equivalent to about 10 years of work by a person soldering discrete components onto printed wiring boards. In the early days of computing, most computer operations were reduced to calculations. Download
