  • The Five Generations Of Computers Webopedia Reference

    Feb 01, 2019· The first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. These computers were very expensive to operate and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions.

  • Cavity magnetron Wikipedia

    The cavity magnetron, or not entirely accurately reduced simply to magnetron, is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators).Electrons pass by the openings to these cavities and cause microwaves to oscillate within, similar to the way a whistle

  • Vacuum Tubes and External Strong Magnetic Fields

    Jun 03, 2018· I don't believe it matters much to a vacuum tube. Many guitar amplifiers (Fender and others of similar construction) have the tubes hanging upside down, with the speaker magnets only inches from the tubes. Some of those speakers have huge magnets. The magnetic field seems to have no effect on the tubes. One possible exception: CRT's.

  • Vacuum tube Wikipedia

    A vacuum tube, an electron tube, valve (British usage) or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.. The type known as a thermionic tube or thermionic valve uses the phenomenon of thermionic emission of electrons from a hot cathode and is used for a number of fundamental

  • Magnetic Drums CHM Revolution

    Magnetic DrumsThe Cold War was gathering steam in 1948. Eager to enhance America’s code-breaking capabilities, the U.S. Navy contracted with Engineering Research Associates (ERA) for a stored program computer. The result was Atlas, completed in 1950.Atlas used magnetic drum memory, which stores information on the outside of a rotating cylinder coated with magnetic iron (ferromagnetic

  • 1st Generation/2nd Generation COMPUTERS

    First Generation The period of first generation: 1946-1959. Vacuum tube based. The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.The vacuum tube was developed by Lee DeForest. A vacuum tube is a device generally used to amplify a signal by controlling the movement of electrons in an evacuated space.
