What is the role of the garbage collector in memory management in automated systems?

Garbage Collector (GC) is a component of the runtime environment that automatically manages memory by freeing memory occupied by objects that are no longer used by the program.

Role of the garbage collector:

• Automatic memory release: developers do not need to manually free memory, reducing the likelihood of errors such as memory leaks or double freeing.
• Memory usage optimization: GC periodically checks objects in memory and removes those with no references, freeing resources.
• Enhanced safety and stability: prevents access to already freed memory.

In Java, the garbage collector runs in the background, tracking objects and their references, and when an object becomes unreachable, its memory is automatically freed, simplifying development and reducing memory management errors.
