Definicja virtual address space for work process

The address space which comprises a text segment a data segment, a dynamical-extendable heap and a dynamically-extendable stack.

The heap grows from below and the stack from above so that the entire virtual address space can be used. 4 Gigabytes of memory can be theoretically addressed in 32-bit systems; a process has circa 2 GB of virtual address space, depending on the operating system.

SAP Memory Management creates the virtual address space from the SAP memory types roll memory, extended memory and process-local heap memory and determines the memory type allocation sequence.
