Garbage (computer science)
REGIONS OF THE MEMORY OF A COMPUTER SYSTEM WHICH WILL NOT BE USED BY THE SYSTEM
Garbage data; Semantic garbage; Syntactic garbage
In computer science, garbage includes data, objects, 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. Because every computer system has a finite amount of memory, and most software produces garbage, it is frequently necessary to deallocate memory that is occupied by garbage and return it to the heap, or memory pool, for reuse.
