The book describes programs known as "tapeworms" which spread through a network for the purpose of deleting data. Researchers writing an early paper on experiments in distributed computing noted the similarities between their software and the program described by Brunner, and adopted that name.
The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax . [ 1 ]
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors.

A pivotal moment in computing history was the publication in the 1980s of the specifications for the IBM Personal Computer published by IBM employee Philip Don Estridge, which quickly led to the dominance of the PC in the worldwide desktop and later laptop markets – a dominance which continues to this day.
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 terminology standardization proper - if one excludes earlier attempts in the field of metrology - started in the International Electrotechnical Commission (IEC), which was founded in London in 1906 following a recommendation passed at the International Electrical Congress, held in St. Louis, United States, on 15 September 1904 ...
Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories (nonterminal) and terminal symbols.
