This was when machine language was developed for the use of computers. The first working von Neumann machine was the Manchester "Baby" or Small-Scale Experimental Machine, developed by Frederic C. Williams and Tom Kilburn at the University of Manchester in 1948 as a test bed for the Williams tube; [81] it was followed in 1949 by the Manchester Mark 1 computer, a complete system, using Williams tube and magnetic drum memory, and introducing index registers. The computer … Large amount of energy … Used for the government on the census. Input and output were based on a punch card. 1940 – 1956: First Generation – Vacuum Tubes. They required AC (alternating current) power for … RAM and ROM concept was introduced in 2nd generation leaving behind magnetic drum concept. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. ENIAC covered 1800 square feet [167 … They were a low-speed computer. It could store only a small amount of information due to the presence of magnetic drums. The cards were fed into a card reader connected to a computer, which converted the sequence of holes to digital information. The scientists at Bell laboratories developed transistor in 1947. The IBM 650 Magnetic Drum Data Processing Machine was announced 2 July 1953 (as the "Magnetic Drum Calculator", ... IBM sometimes refers to the 650 as its first computer, although it is predated by at least ASCC (1943) and SSEC (1947), which were not products, and the 701 (1952), which definitely was. Magnetic drum memories were developed for the US Navy during WW II with the work continuing at Engineering Research Associates (ERA) in 1946 and 1947. Speed of copmuter increased 10times first generation. The use of magnetic drums came about as inventor Gustav Tauscheck invented drum memory, which was a magnetic data storage device. The input and output devices were slow. The first generation of computer history is generally characterized by the widely used vacuum tubes. They were first used in several classified processors, then in the early 1100 computer series and the UNIVAC SS-80 and SS-90 computers.
