Что такое сборщик мусора и как он работает?

Ответ:

Сборка мусора – это низкоприоритетный процесс, который служит в качестве автоматического менеджера памяти, управляющего распределением и освобождением памяти для приложений.

Каждый раз, когда создается новый объект, среда выполнения общего языка выделяет память для этого объекта из управляемой кучи. Пока в управляемой куче есть свободное пространство памяти, среда выполнения продолжает выделять место для новых объектов. Однако память не бесконечна, и как только приложение заполняет пространство, в дело вступает сборщик мусора (Garbage Collector), который освобождает часть памяти.

Когда сборщик мусора выполняет очистку, он проверяет объекты в управляемой куче, которые больше не используются приложением, и выполняет необходимые операции. Сборщик мусора останавливает все запущенные потоки, находит все объекты в куче, к которым не обращается основная программа, и удаляет их. Затем он собирает все объекты, оставшиеся в куче, чтобы освободить место, и корректирует все указатели на эти объекты в стеке и в куче.

Чтобы запустить сборку мусора в коде вручную, выполняем следующую команду:

System.GC.Collect();

NEWS: Telegram supports Facetime video calls NOW!

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
