Babbage’s Difference Engine: Charles Babbage, an English Mathematician in 1822 brought a new break Von through in the development of calculating machines. He introduced a new concept called «Level Difference» which was used largely in future computers. He is also rightly called «Father of Modern Computers».
Computer Logic: Between 1847 and 1857, George Boole, an English logician, devised and perfected an algebraic system, which is now called «Boolean Algebra». In 1890, Dr. Herman Hollerith put forth his idea of coding the data by representing it by punched hole combinations on cards. With this he invented Tabulators.
ENIAC- In 1946, J. Prosper and John Manchu developed ENIAC. It could perform 5000 additions per second, which was amazing at that time. In 1946, John Von Neumann summarized all the concepts and requirements of a computer.
HISTORY OF WWW
The World Wide Web was developed by British computer scientist Timothy Berners-Lee as a project within the European Center for Nuclear Energy Research in Geneva, Switzerland. Berners-Lee first began working with hypertext in 1980s.His implementation of the Web became operational at CERN in 1989, and it quickly spread to universities in the rest of the world through the high-energy physics community of scholars. Groups at the national Center for supercomputing Applications at the University of Illinois in Champaign-Urban also researched and developed Web technology. The use of a web is known to provide a vast opportunity for finding answers to many of our most complex social problems as well.They developed the first major browser, named Mosaic, in 1993. Mosaic was the first browser to come in several different versions, each of which was designed to run on a different operating system. Operating systems are the basic software that control computers.
The architecture of the Web is amazingly straightforward. For the user, the Web is attractive to use because it is built upon a graphical user interface (GUI), a method of displaying information and controls with pictures. The Web also works on diverse types of computing equipment because it is made up of a small set of programs. This small set makes it relatively simple for programmers to write software that can translate information on the Web into a form that corresponds to a particular operating system. The web’s methods of storing information associatively, retrieving documents with hypertext links and naming web sites with URLs make it a smooth extension of the rest of the Internet.
The Web has become a very popular resource since it first became possible to view images and other multimedia on the Internet, a worldwide network of computers, in 1993. The Web offers a place where company’s institutions and individuals can display information about their products, research, or their lives. Anyone with access to a computer connected to the web can view most of that information. A small percentage of information on the web is only accessible to subscribers or other authorized users. The Web has become a forum for many groups and a marketplace for many companies. Museums, libraries, government agencies, and schools make the Web a valuable learning and research tool by posting data and research. The Web also carries information in a wide spectrum of formats. Web is a part of Internet. Users can read text, view pictures, listen to sounds, and even explore interactive virtual environments on the web.
