Garbage Collection
PronunciationGAR-bij kuh-LEK-shun
Definition
Garbage collection is an automatic memory management process where the runtime environment identifies and frees up memory occupied by objects that are no longer in use. This prevents memory leaks by reclaiming space that the application can no longer access.
Where you hear it
In discussions about performance optimization, language runtimes, and memory management strategies.
Examples
The language uses garbage collection to clean up unused objects automatically.
Frequent garbage collection cycles can sometimes cause temporary latency spikes in the application.
Common mistake
Assuming that garbage collection eliminates the need to manage resources entirely; developers still need to manually close file handles or database connections to avoid resource exhaustion.
