Questions tagged [garbage]

Garbage, refers to objects, data, or other regions of the memory of a computer system (or other system resources), which will not be used in any future computation by the system, or by a program running on it.

From a programming point-of-view, garbage is data that has been placed in random access memory space obtained from the operating system that is no longer needed. Freeing the space for reuse is called "garbage collecting".
