Why Python is called garbage collector?
Python deletes unwanted objects (built-in types or class instances) automatically to free the memory space. The process by which Python periodically frees and reclaims blocks of memory that no longer are in use is called Garbage Collection.
What is the difference between garbage collection and Automatic Reference Counting?
Before the introduction of the modern object life cycle management, developers had to keep track of all the objects they created, make sure they explicitly remove them when done. They are two common modern methods for the memory management namely Garbage Collection and Automatic Reference Counting.
When does the garbage collector invoke the destructor?
They are actually very rare in managed code, and are usually used to ensure unmanaged resources are released. If an object has a destructor/finalizer, the garbage collector invokes it around the same time as collection (maybe in the next pass). Garbage collection is non-deterministic – it happens when it happens – often relating to memory pressure.
How does the garbage collector work in.net?
The garbage collector is part of the framework, automatically manages memory, and non-deterministically collects unreferenced objects to avoid memory leaks. The garbage collector is a part of the .NET environment that keeps track of objects and makes sure that objects are removed from memory when they are no longer needed.
Which is a disadvantage of using garbage collection?
But Garbage collection has disadvantages like consuming additional memory (RAM) to run those algorithms and this has a major performance impact. Further, the objects aren’t garbage collected at the very instant. It takes its own time it has a performance impact as well.

How does garbage collection work in GC root?
All of the heap memory that is not occupied by marked objects is reclaimed. It is simply marked as free, essentially swept free of unused objects. When objects are no longer referenced directly or indirectly by a GC root, they will be removed.
Which is the default reference in garbage collection?
By default, references are strong where storing an object reference will force the object to stay alive until the reference is removed. Alternatively, a reference can be marked as weak.
