Garbage collection is the systematic recovery of pooled computer storage that is being used by a program when that program no LONGER NEEDS the storage. This frees the storage for use by other programs 

(or processes within a program). It also ensures that a program using increasing amounts of pooled storage does not reach its quota (in which case it may no longer be able to FUNCTION). 

Garbage collection is an automatic memory management feature in many modern programming LANGUAGES, such as Java and languages in the .NET framework. Languages that use garbage collection are often interpreted or run within a virtual machine like the JVM. In each case, the environment that runs the code is also responsible for garbage collection.
