Memory Management in an Operating System

Memory Management in Operating Systems

Key Concepts

• Memory Allocation: Assigning memory to programs and data.
• Memory Protection: Preventing programs from accessing unauthorized memory.
• Virtual Memory: Using disk storage to supplement physical memory.

Memory Management Techniques

• Paging: Dividing memory into fixed-size blocks (pages).
• Segmentation: Dividing memory into variable-size blocks (segments).
• Swapping: Moving programs or data between memory and disk storage.

Benefits

• Efficient Memory Use: Optimizing memory allocation and deallocation.
• Improved Performance: Reducing memory-related errors and crashes.
• Enhanced Security: Protecting memory from unauthorized access.
