Alan Turing is credited with being the first person to come up with a theory for software in 1935, which led to the two academic fields of computer science and software engineering. The first generation of software for early stored-program digital computers in the late 1940s had its instructions written directly in binary code, generally ...
The integrated circuit is an essential invention to produce modern software systems. [2] The first use of the word software 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 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 ...
The Lisa was one of the first personal computers with a graphical user interface (GUI) that was sold commercially. It ran on the Motorola 68000 CPU and used both dual floppy disk drives and a 5 MB hard drive for storage. The machine also had 1MB of RAM used for running software from disk without rereading the disk persistently. [72]

The Apache HTTP Server became the most-used web-server software, a title that still holds as of 2015. [37] Systems based on a common "stack" of software with the Linux kernel at the base, Apache providing web services, the MySQL database engine for data storage, and the PHP programming language for providing dynamic pages, came to be termed ...
Timeline of computing presents events in the history of computing organized by year and grouped into six topic areas: predictions and concepts, first use and inventions, hardware systems and processors, operating systems, programming languages, and new application areas.
Between the mid-1940s and 1950s, various developments were made in computer software.Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952).
