Speaking of the heap, it comes next in our plunge into address space. The heap provides runtime memory allocation, like the stack, meant for data that must outlive the function doing the allocation, unlike the stack. Most languages provide heap management to programs. Satisfying memory requests...

Instances of SQL Server that are running on Microsoft Windows 2000 use static AWE memory allocation, and instances that are running on Microsoft Windows Server 2003 use dynamic AWE memory allocation. Note Support for AWE is available only in the SQL Server Enterprise, Standard, and Developer ...
4.5.1 Static Versus Dynamic Allocation of Private Memory Resources Memory can be allocated to a process in two ways. Static memory allocation is performed when a process is created, based directly on the declarations of variables in the code. For example, if an array of 20 characters is decla...
I hope I’ve given you a strong foundation for identifying, diagnosing and repairing memory leaks in your Windows Store apps. Leaks often result from misunderstandings of how data allocation and reclamation occur. Knowledge of these nuances—combined with easy tricks such as explicitl...
