![]() It was a mechanical computer that took input from punch cards. It was a steam-powered calculating machine used to solve numerical tables such as logarithmic tables.Ĭharles Babbage created another calculating machine, the Analytical Engine, in 1830. It was a mechanical computer that could do basic computations. In the early 1820s, Charles Babbage created the Difference Engine. It was a digital mechanical calculator known as the stepped reckoner because it used fluted drums instead of gears. In 1673, a German mathematician-philosopher named Gottfried Wilhelm Leibniz improved on Pascal’s invention to create this apparatus. It was a wooden box with gears and wheels inside. It is thought to be the first mechanical and automated calculator. Pascaline was invented in 1642 by Biaise Pascal, a French mathematician and philosopher. It was also the first machine to calculate using the decimal point system. ![]() For calculating, this instrument used 9 separate ivory strips (bones) marked with numerals to multiply and divide. John Napier devised Napier’s Bones, a manually operated calculating apparatus. The abacus operator moves the beads according to certain guidelines to complete arithmetic computations. It’s a wooden rack with metal rods with beads attached to them. ![]() Let us look at a few of the early-age computing devices used by mankind.Ībacus was invented by the Chinese around 4000 years ago. More computing devices were produced as technology advanced and the human intellect improved over time. People used sticks, stones, and bones as counting tools before computers were invented. He also works as a senior research scientist at LCS which has now become the Computer Science and Artificial Intelligence Laboratory.A computer is an electronic machine that collects information, stores it, processes it according to user instructions, and then returns the result.Ī computer is a programmable electronic device that performs arithmetic and logical operations automatically using a set of instructions provided by the user. He has served as director of the consortium since then. In 1994, Berners Lee founded the World Wide Web Consortium at the Laboratory of Computer Science (LCS) at the Massachusetts Institute of Technology in Boston. It explained the World Wide Web concept and gave users an introduction to getting started with their own websites. The world's first website,, was launched on 6 August 1991. He also created the first web browser and editor. In 1989, Berners Lee published a paper called 'Information Management: A Proposal' in which he married up hypertext with the Internet, to create a system for sharing and distributing information not just within a company, but globally. In 1984, Berners Lee's returned to CERN, which was also home to a major European Internet node. He also built a prototype called 'Enquire'. In 1980, while working at CERN, the European Particle Physics Laboratory in Geneva, he first described the concept of a global system, based on the concept of 'hypertext', that would allow researchers anywhere to share information. He studied physics at Oxford University and became a software engineer. Timothy John Berners Lee was born on 8 June 1955 and grew up in London. © Berners Lee is a British computer scientist who invented the World Wide Web.
