What is meant by Generations of Garbage Collector in C#? Is it different from the concept or is GENERATION only a term used to represent the time period?

C# garbage collection belongs to the tracing variety. It's often called a generational approach since it employs the concept of generations to figure out which objects are eligible for collection. Memory is divided into spaces called generations. The collector starts claiming objects in the youngest generation.
Gen0, Gen1 & Gen2 are the generations in . net GC. New objects created in Gen0. objects survived on Garbage Collection will be moved to the next generation. GC will be triggered when there is no space in each generations.
Generations. The . NET Garbage Collector has 3 generations and each generation has its own heap that that is used for the storage of allocated objects.
There are four types of the garbage collector in Java that can be used according to the requirement: Serial Garbage Collector. Parallel Garbage Collector. Concurrent Mark Sweep (CMS) Garbage Collector.
A GC generation relates to how many garbage collections an object survives.
All objects start in generation 0. When a garbage collection occurs, and a generation N object cannot be collected, it is moved to generation N+1.
The generations are used to performance optimize garbage collection. It is generally true that generation 0:
Therefore, when garbage collection occurs, the garbage collector starts by collecting generation 0, which will be quick. If enough memory could be released, no need to look at the older generations, and therefore, collection can happen quickly.
Books could be written about the subject; but to start with, there is some great details in this article, or the reference here.
