Garbage Collector is a piece of computer programming code which is responsible for freeing up memory space on a computer by cleaning out objects which are no longer being used. The Garbage Collector works by seeking out and collecting unused objects. The main purpose of Garbage Collection is to make sure that memory resources remain available for reuse.

The Garbage Collector can work in a number of ways, but the most common way is Automatic Garbage Collection. This is where the Garbage Collector runs by itself, freeing up memory which is no longer being used. This can be done in a number of different ways, such as by running through the memory and seeking out unused or unreachable objects, or by using a tracing algorithm which looks at objects and follows the paths to determine if they are still being used.

Another way of using the Garbage Collector is Manual Garbage Collection. This requires human interaction, and is used when the user needs to manually clean up memory space. This is usually done when objects become too large or are no longer being used. This can be done by either deleting the objects manually, or by instructing the Garbage Collector to do the cleaning up for you.

No matter which way Garbage Collection is used, it is an important process that ensures that memory resources remain available for reuse. Without Garbage Collection, a computer will quickly become full of objects which are not being used, making it difficult for the computer to run efficiently and quickly.
