На сегодняшний день появилось огромное количество аппаратных средств персональных компьютеров различных производителей, которые выполняют самые разные задачи: ввод информации, выполнение кода программ, вывод результатов работы и т.д. Порой становится важной возможность определения конфигурации при не имении на руках документации на установленное оборудование и без разборки системного блока. В этом случае приходят на помощь программы специально разработанные для решения подобного рода задач – программы определения конфигурации компьютера.
