Программирование
Computer programming in general is the process of writing, testing, debugging, and maintaining the source code and documentation of computer programs. This source code is written in a programming language, which is an artificial language often more restrictive or demanding than natural languages, but easily translated by the computer. The purpose of programming is to invoke the desired behavior (customization) from the machine. The process of writing high quality source code requires knowledge of both the application's domain "and" the computer science domain. The highest-quality software is thus developed by a team of various domain experts, each person a specialist in some area of development. But the term "programmer" may apply to a range of program quality, from hacker to open source contributor to professional. And a single programmer could do most or all of the computer programming needed to generate the proof of concept to launch a new "killer" application.
