Assignment 1.1 History timeline of the computer

• 1939 Hewlett-Packard is founded. David Packard and Bill Hewlett found Hewlett-Packard in a Palo Alto, California. Their first product was the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers.
• 1940 The Complex Number Calculator (CNC) is completed. George Stibitz demonstrated the CNC at an American Mathematical Society conference at Dartmouth College. Stibitz performed calculations remotely on the CNC using a Teletype connected via special telephone lines. This is the first demonstration of remote access computing.
• 1941 Konrad Zuse finishes the Z3 computer. Using 2,300 relays, the Z3 used floating point binary arithmetic and had a 22-bit word length.
• 1942 The Atanasoff-Berry Computer (ABC) is completed. The ABC was designed and built by Professor John Vincent Atanasoff and graduate student Cliff Berry between 1939 and 1942.
• 1944 Harvard Mark-1 is completed. Created by Howard Aiken, and designed and built by IBM, the Harvard Mark-1 was a room-sized relay-based calculator. This machine had a fifty-foot long camshaft that synchronized the machine’s thousands of component parts.
• 1946 The first glimpse of the ENIAC, a machine built by John Mauchly and J. Presper Eckert that improved by 1,000 times on the speed of its contemporaries.
• 1949 Maurice Wilkes assembled the EDSAC, the first practical stored-program computer, at Cambridge University. For programming the EDSAC, Wilkes established a library of short programs called subroutines stored on punched paper tapes.
• 1950 The first commercially produced computer was built called the ERA 1101 by the Engineering Research Associates of Minneapolis.
• 1953 IBM shipped its first electronic computer, the 701. During three years of production, IBM sold 19 machines to research laboratories, aircraft companies, and
