many years after the War. And for not being widely known it had little direct influence on the development of later computers. "Page 22" 3. Two problems associated with vacuum tubes are that they are very power consuming devices and the size of the vacuum tubes. "Video - Part 3" 4. Transistors were better than the vacuum tube because they were smaller‚ faster‚ more reliable‚ and cheaper to mass produce. But the problem with transistors was they still have to be hand-wired which limits how small

How many inventions in your lifetime can you think of that have changed everything in our society today? Computers have taken over today ’s society. From everyday tasks to moving satellites in space‚ PCs have revolutionized almost everything in our society. Computers weren ’t always this complicated though‚ and were around a long time before anyone even knew what the word "computer" meant. The Abacus was the first known machine developed to help perform mathematical equations. From what researchers

year 1957‚ included computers that used vacuum tubes‚ drum memories‚ and programming in machine code. Computers at that time where mammoth machines that did not have the power our present day desktop microcomputers. In 1950‚ the first real-time‚ interactive computer was completed by a design team at MIT. The "Whirlwind Computer‚" as it was called‚ was a revamped U.S. Navy project for developing an aircraft simulator. The Whirlwind used a cathode ray tube and a light gun to provide interactively

Lee De Forest Lee De Forest was born Aug. 26‚ 1873‚ Council Bluffs‚ Iowa. De Forest was the son of a Congregational minister. His father moved the family to Alabama and there assumed the presidency of the nearly bankrupt Talladega College for Negroes. Excluded by citizens of the white community who resented his father ’s efforts to educate blacks‚ Lee and his brother and sister made friends from among the black children of the town and spent a happy although sternly disciplined childhood

microprocessor: the vacuum tube‚ the transistor‚ and the integrated circuit. The Vacuum Tube American physicist Lee De Forest invented the vacuum tube in 1906. However‚ one must look back to 1879 when Thomas Edison first revealed the incandescent electric light bulb to understand how De Forest developed his idea. Edison ’s invention consisted of a conducting filament mounted in a glass bulb. Electricity passing through the filament caused it to heat up and created a vacuum that prevented the filament

academic field and the beginning of a substantial worldwide industry. Computer Hardware originated from the 1960’s is marked by the conversion from vacuum tube to solid state devices such as the transistor and later the integrated circuit. By 1959 discrete transistors were considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive. Computer main memory slowly moved away from magnetic core memory devices to solid-state static and dynamic semiconductor
