Chapter 9

1. The stack is a relatively small segment of memory allocated by the compiler that keeps track of the memory necessary for running the application. The stack has LIFO semantics and grows and shrinks as the program execution is invoking functions or returning from functions. The heap, on the other hand, is a large segment of memory that the program may use to allocate memory at runtime, and which, in .NET, is managed by the CLR. Objects of value types are, typically, allocated on the stack, and objects of reference types are allocated on the heap.
2. The managed heap has three memory segments called generations. They are named generation 0, 1, and 2. Generation 0 contains small, and usually short-lived, objects such as local variables or objects instantiated for the lifetime of a function call. Generation 1 contains small objects that have survived a garbage collection of memory from generation 0. Generation 2 contains long-lived small objects that have survived a garbage...
