Goals of Memory Virtualization

1. Transparency

2. Protection

3. Efficiency

4. Sharing




Transparency

Process is unaware of sharing




Protection

Cannot corrupt OS or other process memory

, Efficiency

Does not waste memory or slow down processes




Sharing

Enable sharing between cooperating processes




Stack

Stores local variables




Heap

Stores dynamic memory (Pointers, addresses, etc.)




Program Code

Stores instructions




Data

Stores global variables




Possible Solutions for Mechanisms

1. Time Sharing
