পৃথিবীর প্রথম সফটওয়্যার কত সালে আবিষ্কৃত হয় ?
The very first time a stored-program computer held a piece of software in an electronic memory, and executed it successfully, was 11am, 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, it performed division of 262,144 by repeated subtraction then checked if the remainder was zero. If not, it decremented the trial divisor by one and repeated the process. Google released a tribute to the Manchester Baby, celebrating it as the "birth of software". In the late 1950's and early 1960's, a popular innovation was the development of computer languages such as Fortran, COBOL and BASIC. These languages allowed programs to be specified in an abstract way, independent of the precise details of the hardware architecture of the computer. The languages were primarily intended only for specifying numerical calculations.
