The very first time a stored-program computer held a piece of software in electronic memory and executed it successfully, was 11 am 21 June 1948, at the University of Manchester, on the Manchester Baby computer. It was written by Tom Kilburn, and calculated the highest factor of the integer 2^18 = 262,144. Starting with a large trial divisor ...
The integrated circuit is an essential invention to produce modern software systems. [2] The first use of the word software to describe computer programs is credited to mathematician John Wilder Tukey in 1958. [3] The first programmable computers, which appeared at the end of the 1940s, [4] were programmed in machine language.
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
The use of rapid-prototyping evolved to entire lightweight methodologies, such as Extreme Programming (XP), which attempted to simplify many areas of software engineering, including requirements gathering and reliability testing for the growing, vast number of small software systems. Very large software systems still used heavily documented ...
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
Designed the software of the first transistor-based computer. Also influenced the ALGOL programming language. 1975, 1985 Rubin, Philip: Developed pioneering computational speech synthesis systems for use in the experimental study of speech perception and production, including articulatory synthesis and sinewave synthesis.

CSIR Mk I (later known as CSIRAC), Australia's first computer, ran its first test program. It was a vacuum-tube-based electronic general-purpose computer. Its main memory stored data as a series of acoustic pulses in 5 ft (1.5 m) long tubes filled with mercury. 1949 United Kingdom
