Memory leaks and dangling pointers are the main issues of the manual memory management. You delete a parent node in a linked list, forgetting to delete all its children first — your memory is leaking. You delete an object chain in correct order — but suddenly your program crashes since you forgot about second owner of this resource, which now tries to dereference a null-pointer.

To avoid these issues, most of the modern high-level programming languages implement automatic memory management. You allocate objects manually, however don’t bother with their deallocation: a special program, garbage collector, knowns how to automatically deallocate them correctly, and reclaim for future reuse.

In the Essentials of Garbage Collectors class we study all different techniques and algorithms related to the automatic memory management, which are used today on practice.
