Information Technology

The growth and progress of every sector of the country today depends on the level of Information Technology. Furthermore, technology is not important only at the work place, but also in our everyday life; whether it is working with the microwave oven which is a cooking appliance or a super computer, an appliance is based on information technology, technology helps everywhere.

From hi-tech industry to an education system, Information Technology footprints can be seen everywhere. Likewise, Information Technology is one of the essential features for the overall development of a country.

Meaning of Information Technology The technology, which is exclusively designed to store, process, and transmit information, is known as Information Technology.

Diffusion of e-governance on a large scale.

Participation of public in governance and policy making. Fast economic development. Development of remote areas. Technology helps the police in nabbing the criminals.

The judiciary and other administrative services can also take the help of technology to make work easier and faster.

Charles Babbage developed the difference engine which tabulated polynomial equations using the method of finite differences. Difference Engine There were lots of different machines created during this era and while we have not yet gottent to a machine that can do more than one type of calculation in one, like our modern-day calculators, we are still learning about how all of our all-in-one machines started.

Looking for other ways to read this?

Also, if you look at the size of the machines invented in this time compared to the power behind them it seems to us absolutely ridiculous to understand why anybody would want to use them, but to the people living in that time ALL of thse inventions were HUGE. The electromechanical age can be defined as the time between and These are the beginnings of telecommunication.

The telegraph was created in the early s. Morse code was created by Samuel Morse in The telephone one of the most popular forms of communication ever was created by Alexander Graham Bell in The first radio developed by Guglielmo Marconi in All of these were extremely crucial emerging technologies that led to big advances in the information technology field.

The first large-scale automatic digital computer in the United States was the Mark 1 created by Harvard University around This computer was 8ft high, 50ft long, 2ft wide, and weighed 5 tons - HUGE. It was programmed using punch cards.

How does your PC match up to this hunk of metal? It was from huge machines like this that people began to look at downsizing all the parts to first make them usable by businesses andeventually in your own home.

It can be defined as the time between and right now.

The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems. This computer was designed to be used by the U. Army for artillery firing tables. It mainly used vacuum tubes to do its calculations. There are 4 main sections of digital computing.

Rotating magnetic drums were used for internal storage.

The second generation replaced vacuum tubes with transistors, punch cards were replaced with magnetic tape, and rotating magnetic drums were replaced by magnetic cores for internal storage. The third generation replaced transistors with integrated circuits, magnetic tape was used throughout all computers, and magnetic core turned into metal oxide semiconductors.

An actual operating system showed up around this time along with the advanced programming language BASIC.The assembly language instructions correspond, one-to-one, to machinelanguage instructions. Fixed-head drives naturally must have a head for each track which costs more , but save head-movement time in random access.

Thus it was not long before programmers devised much more humanly natural languages, which are generically called higher-level or algebraic languages.

It also allows a further proposition. We will design systems which use information as a resource and expect it to be totally consistent.

It is also possible to have a switching device, which receives addressed data and directs them to the appropriate recipient device, rather like a central post office. While the kernel will contain the rudiments of a file-handling system to create, destroy, list, locate, and transfer files , there will also be utilities for further management of these.

The same applies to routines for computing, for example, sines, cosines, logarithms, etc. Newspapers, television and the radio present us with their own ideas of what information should be. The two are interrelated, data being the input to a process, and information the output.
