DVD (DIGITAL VIDEO DISC)

After the futuristlc-looking compact dtse (CD) took the  audio market by srorm-consigning the humble  cassette rape to the back of  billion cupboardS-it  was only a matter of time beFore technolagicalwizards  set their sights on abolishing the VHS tape.     Although the technology for LaserDise already existed, it never really took off in the way that CD technology did, and so the market for a compact digital video disc was still very much open. The first proposals for a high-density CD were put forward in 1993, leading to the creation of two competing formats. Electronic powerhouses Sony and Philips led their collected investors forward with the MMCD format. going head to head with indusrry giants Toshiba, Masushita, and Time Warner's effort. the SD. Then, in 1995, a combined effort-known as the DVD-was off,cially announced and consequently developed by a consorrium of ten companies.

Who invented the Internet?

Advanced Research Project Agency develops the Internet. In 1963, Advanced Research Project Agency(ARPA) unit,set up by us defense department,began to build a computer network.The reason behind this was the fear of nuclear threat by Soviet Union,it aimed to link computers at different locations,so the researchers could share data electronically without having fixed route between them which made their system less vulnerable to attack--even nuclear ones.  The mechanism        Schematic diagram by Larry roberts Data was converted into telephone signals using a modem( Mo dulator- Dem odulator), Developed by AT&T in the late 1950s.In 1960s,key advances were made,including "packet switching" -- a system of packaging,labelling and routing data that enables it to be delivered across the network between machines.Paul baran proposed this system,which broke each message down into tiny chunks.This would be fired into the network,which would then route("swit...

Have you ever heard of a train powered by a Magnet?

Image
The Maglev train route in Shanghai Magnetically levitated (maglev) glide above track,propelled by superconducting magnets.The principle is more than a century old,but initially the huge electrical current needed to provide a sufficiently strong magnetic field were impractical.The breakthrough came when the two physicists,Gordon Danby and James Powell,at Brookhaven national laboratory decided to use high temperature superconductors as electromagnets.They obtained a patent for the technology in 1968,and by 1979,visitors to transportation exhibition in Hamburg,Germany ,were enjoying a short test run on transrapid maglev train.        Maglev trains need a guiding track and the carriages float above it.Changing the field produced by electromagnets in the guideway pulls the train along.The only friction is due to air resistance,so extremely high speed are possible.Change in field strength can produce very high acceleration,and much more variable track gradients c...
