The evolution of software engineering is notable in a number of areas: Emergence as a profession: By the early 1980s software engineering had already emerged as a bona fide profession, [2] to stand beside computer science and traditional engineering.
The first modern theory of software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). [4] This eventually led to the creation of the twin academic fields of computer science and software engineering, which both study software and its creation. Computer science is ...
The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
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.
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining of software applications.It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive .
The hardware engineer deals (more or less) exclusively with the hardware device; the software engineer deals (more or less) exclusively with the computer program; and the systems engineer is responsible for seeing that the program is capable of properly running within the hardware device, and that the system composed of the two entities is ...
Early software had a physical footprint, such as cards, tapes, and other media. The first software configuration management was a manual operation. With the advances in language and complexity, software engineering, involving configuration management and other methods, became a major concern due to issues like schedule, budget, and quality ...
