Great ICT Personalities

Many scientists, visionaries and engineers have contributed significantly to the development of Information and Communication Technology. Cable connection and wireless system, acceleration of computers' counting power and the development of microelectronics have ensured rapid growth of ICT.

Charles Babbage (1791-1871), an English engineer and mathematician, first introduced computer and developed the device. He is regarded as the father of modern computer. He invented Difference Engine In 1991, in the Science Museum of London, an engine was made according to the design of Babbage, and it worked properly as expected and later, he designed a calculating machine called Analytical Engine.

Ada Lovelace (1815-1852), the daughter of poet Lord Byron first thought about how the process of calculation could be made more effective. She became interested in science and mathematics since her childhood encouraged by her mother. When she met Charles Babbage in 1833, she brought before him the concept of 'programming' to use in his analytical engine. That is why Ada Lovelace is honored as the pioneer of programming concept. Babbage delivered a lecture about his engine in 1842 at Turin University. Then Ada with the help of Babbage explained the ways how the engine could work. She marked it in numerical order, while describing its mode of working. In 1953, when the note was published again one hundred years after the death of Ada, the scientist realized that it was Ada who put forward the idea about Algorithm of programming.

Important progress was done in physics during that period along with the inventions of Babbage and Ada.

Scientist James Clerk Maxwell (1831-1879), combining the electric energy and magnetic force, put forth the theory of Electromagnetic Force which opened a possibility of sending wireless messages from one place to another.

Bengali scientist Jagadish Chandra Bose (1858-1937) became successful for the first time in sending wireless messages from one place to another. In 1895, he successfully did it by using microwave.

But, Italian scientist Guglielmo Marconi (1874-1937) succeeded first in doing the same work by radio wave. That is why he is acknowledged as the inventor of radio.

In the 20th Century, after the development of electronics, IBM Company first built mainframe computer after the development of electronics. In 1971, making of cost-saving computer. In 1971, with the invention of the microprocessor, it became easier to make affordable computers. In the 60s and 70s, using the Internet Protocol, Arpanet was invented the Internet protocol. The interrelation among the computers through network started developing since then, and the invention of the Internet is the outcome. In 1971, American programmer Raymond Samuel Tomlinson introduced first electronic mail communication through ARPANET. He is the pioneer of inventing e-mail system.

After the invention of microprocessor, making of personal computer by using this device started in the USA. Steve Jobs (1955-2011) and his two friends Steve Wozniak and Ronald Wayne started a company named Apple Computer on April 1, 1976. This company is one of the biggest rganizations in the world. The development of personal computer has been carried out by this company.

IBM Company put the responsibility of developing the operating system for personal computers on 'Microsoft' of William Henry Bill Gates (born on October 26, 1955). They successfully developed MS DOS and Windows operating system. At present, most of the computers of the world are run by the operating system software of Microsoft Company of Bill Gates.

In 1989, during the development of the Internet, a British computer scientist proposed and later on successfully invented information anagement by using Hypertext Transfer Protocol (http) and successfully invented it. Sir Timothy John 'Tim' Berners Lee is known as the pioneer of World Wide

Weave (WWW). The Internet connection spread out throughout the world for its development. A strong economic field has been created on the Internet and different types of application software have been developed.

The learner of Harvard University Mark Zuckerberg (Born on may 14, 1984) and his four friends are the pioneers of creating social networking system facebook in the Internet. At first, it was confined to the university students, but according to the statistics of May 2014, at least 119 crore people of the world have been using facebook. Many people in our planet use facebook for social networking.
