Do you know the following really? It's good to share even such small maters for beginers.
• ENIAC, the first electronic computer, appeared 50 years ago. The original ENIAC was about 80 feet long, weighed 30 tons, had 17,000 tubes. By comparison, a desktop computer today can store a million times more information than an ENIAC, and 50,000 times faster.
• From the smallest microprocessor to the biggest mainframe, the average American depends on over 264 computers per day.
• The first "modern" computer (i.e., general-purpose and program-controlled) was built in 1941 by Konrad Zuse. Since there was a war going on, he applied to the German government for funding to
build his machines for military use, but was turned down because the Germans did not expect the war to last beyond Christmas.
• The computer was launched in 1943, more than 100 years after Charles Babbage designed the first programmable device. Babbage dropped his idea after he couldn't raise capital for it. In 1998, the Science Museum in London, UK, built a working replica of the Babbage machine, using the materials and work methods available at Babbage's time. It worked just as Babbage had intended.
E-Mail
The first e-mail was sent over the Internet in 1972.
