Which part of memory is involved in the garbage collection?

Java garbage collection is the process by which Java programs perform automatic memory management. Java programs compile to bytecode that can be run on a Java Virtual Machine, or JVM for short. When Java programs run on the JVM, objects are created on the heap, which is a portion of memory dedicated to the program.

What is garbage collection in memory?

In computer science, garbage collection (GC) is a form of automatic memory management. The garbage collector attempts to reclaim memory which was allocated by the program, but is no longer referenced—also called garbage.

Which part of memory is involved in garbage collection Mcq?

Q) Garbage collection in Java is Memory occupied by objects with no reference is automatically reclaimed for deletion. Java deletes all unused java files on the system.

Which has highest memory requirement?

Which of the following has the highest memory requirement? Explanation: JVM is the super set which contains heap, stack, objects, pointers, etc. 2.

How does garbage collection work in a computer?

It is run on space which is commonly allocated from a large pool of memory referred to as the heap. The timing of garbage collection is up to the garbage collector. Typically, the entire heap or a sub-part of it is collected either when it fills up or when it reaches a threshold percentage of occupancy.

How much virtual memory does a garbage collector have?

By default, on 32-bit computers, each process has a 2-GB user-mode virtual address space. As an application developer, you work only with virtual address space and never manipulate physical memory directly. The garbage collector allocates and frees virtual memory for you on the managed heap.

Where does garbage collection take place in Java?

Garbage collection is a complex task which takes time and resources of its own. It is run on space which is commonly allocated from a large pool of memory referred to as the heap. The timing of garbage collection is up to the garbage collector.

How does the garbage collector look for unreachable objects?

The garbage collector considers unreachable objects garbage and releases the memory allocated for them. During a collection, the garbage collector examines the managed heap, looking for the blocks of address space occupied by unreachable objects.
