WebSo, Garbage Collector is nothing but, it is a feature provided by CLR which helps us to clean or destroy unused managed objects. Cleaning or destroying those unused managed objects basically reclaim the memory. Note: The Garbage Collector will destroy only the unused managed objects. It does not clean unmanaged objects. WebGarbage collection is to release memory when the object is no longer in use. This system destroys the unused object and reuses its memory slot for new objects. You can imagine this as a recycling system in computers. Python has an automated garbage collection. It has an algorithm to deallocate objects which are no longer needed.
