1. Main memory techniques
2. Cache memory techniques
3. Virtual memory techniques
4. Associate memory techniques

Answer 1

Correct Answer - Option 3 : Virtual memory techniques

• Virtual Memory is a space where large programs can store themselves in form of pages while their execution and only the required pages or portions of processes are loaded into the main memory.
• This technique is useful as large virtual memory is provided for user programs when a very small physical memory is there.
• Techniques that automatically move program and data blocks into the physical main memory when they are required for execution are called virtual-memory techniques.
