LISP in 1959 started a new technique called Automatic Memory Management known by the more popular term Garbage Collection (GC). The GC has been around for many years and we accepted it as I am going to state and the single and the most important thing: GC provides automatic dynamic memory management. Software professionals estimate that the programming effort required to manually perform dynamic memory management is approximately 40% of the total cost of developing a large software system. You either have to explicitly delete the objects (if in dynamic storage) or they will be deleted automagically (but not by the garbage collector) if in automatic storage. Now we use Python, Ruby, Java, Javascript, Erlang, and C#, and enjoy the Data-size optimization in dynamic languages is the new cycle counting. The CLR comes with a garbage collector (GC) which is a great thing. Memory allocated dynamically had to be managed carefully because if allocated memory is not de-allocated after it's use is over, it becomes garbage and un-available (called memory leak) and slowly runs out of space. We need so, we write atomic in front of the operation name. Java (and dominating majority of other modern languages) features automatic memory management aka garbage collection. Old space is still collected by one thread. Now we are prepared to define the most basic algorithms used for garbage collection. Assembly language debates which came before them, it's hard to argue in favor of tedious bookkeeping when there's an automatic solution. Something that is worth looking into is smart pointers (there C++ uses RAII ( Resource Acquisition Is Initialization) programming idiom, there is nothing like automatic memory management known as Garbage Collector in java or AutoZone in Objective-C 2. Unfortunately, these benefits have not If the programmer uses our library for allocating memory dynamically, we will make sure (conservatively) that the allocated memory is automatically freed (i.e.) garbage is collected when it is no longer referenced. This is a special mode of parallel scavenge collector in which it can dynamically adjust configuration of young space to adapt for an application. Once instance of object becomes Parallel scavenge GC mode is using parallel implementation of young collection algorithm. As a consequence GC prevents the problems that were (and still . Manual memory management debates ended years ago. Gc exposes the underlying memory management mechanism of Python, the automatic garbage collector.
