Since garbage collector always run at the back end there will be extra overhead for the memory. Therefore garbage collector is given the lowest priority in .NET Framework. In .NET Framework, garbage collection system is based on the Mark and Compact algorithm that involves removing of objects that have gone out of scope and compacts all the remaining objects at the beginning of the address space. The space allotted for the application is also referred to as managed heap.
