Abacus the First Computer
An abacus a echanical device used to assist a person in performing mathematical calculations. The chinese in 300 BC inveted this. The abacus does not actually do the computing, as today's calculators do. It helps people keep track of numbers as they do the computing. People who are good at using an abacus can often do calculations as quickly as a person who is using a calculator -
Telephone
Alexander Graham Belland his assitant, Thomas A. Watson, invented the telephone accidently when he was trying to invent a device that could send multiple telegraphs at the same time. The first telephone didn’t have a bell, so the caller had to tap the phone with a hammer to let the receiver know a call was being sent to them. It was Thomas Watson who invented the bell.Also, the telephone helped people spread news around faster. -
The Lightbulb
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours. -
Car invented
car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. -
Radio
The radio, or "wireless," was born in 1895 when Italian physicist and inventor Guglielmo Marconi (1874-1937) experimented with wireless telegraphy. The following year he transmitted telegraph signals, through the air, from Italy to England. By 1897 Marconi founded his own company, Marconi's Wireless Telegraph Company, Ltd., in London and began setting up communication lines across the English Channel to France, which he accomplished in 1898. -
Airplane invented
The inventors of the first airplane were Orville and Wilbur Wright. As part of the Wright Brothers' systematic practice of photographing every prototype and test of their various flying machines, they had persuaded an attendant from a nearby lifesaving station to snap Orville Wright in full flight. The craft soared to an altitude of 10 feet, traveled 120 feet, and landed 12 seconds after takeoff. -
Television
John Logie Baird showed a working television system to the public in 1925.
Baird was a Scottish engineer and inventor of the world's first working television system in Hastings, England, in 1923. His public demonstration subsequently took place in Selfridges, a department store in London England, during March 1925. The system was successful enough to become commercialized, and the BBC began the world's first regular television broadcasts in January 1929, using Baird's system. -
The Internet
Internet was not invented by a single person or company. It was developed by a team of experts. These developments and ideas about the internet started nearly a quarter of century back.National Science Foundation took the management in 1990 and then it was known as NSFinet which further contributed with its researches by connecting it to ESNET in universities of North America. The use of internet was exploded after 1990. In 1992 internet access was available for common public and its use explo -
Cellphone
It took 63 years for the first cell phone to be released to the public in Japan. It was invented by a man named Martin Cooper in 1973 while he was working for Motorola.
The first cell phone released by Motorola was the DynaTec phone. It cost a whopping $3,500 and did not sell particularly well to the general public. -
Space Shuttle
The space shuttle program was initiated on January 5, 1972 with President Nixon's announcement that NASA would begin development on a manned reusable space shuttle system. The first complete orbiter, Enterprise, was completed on September 17, 1976. The first fully functional space shuttle, Columbia, was delivered to the Kennedy Space Center on March 25, 1979. Columbia's first launch was on April 12, 1981. -
Creation of the Smartphone
Technology has made such an impact on society that most people won’t leave home without their cell phone, and their computer has become their best friend. This is why one of the most life-changing pieces of technology for many has been the smartphone — an all-in-one, portable device that combines the functions of a cell phone with the functions of a computer.
The first smartphone was invented by IBM in 1992. It was nicknamed, “Simon,” and had a plethora of features including a calendar, address. -
Electricity was found
Electricity has always been around because it naturally exists in the world. Lightning, for instance, is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock, that is really static electricity moving toward you.
