Top 10 List of Week 05

1. What is Virtual Memory ?
   This page will help you solve the question above. It also tell you how virtual memory works.

2. COW - Copy On Write
   This page explain about copy on write, where COW is a resource management technique. One of its main use is in the implementation of the fork system call in which it shares the virtual memory of the OS.

3. Page Replacement Algorithm
   This page tells some page replacement algorithms (FIFO, Optimal Page Replacement, and Least Recently Used). It also gives us some example to make our understanding clearer.

4. Least Recently Algorithm Page Replacement
   Least Recently Used (LRU) algorithm is a Greedy algorithm where the page to be replaced is least recently used. For more example, just check it out.

5. Second Chance Page Replacement Policy
   In the Second Chance page replacement policy, the candidate pages for removal are considered in a round robin matter, and a page that has been accessed between consecutive considerations will not be replaced.

6. Allocating kernel memory
   In this page, it explains about Two strategies for managing free memory that is assigned to kernel processes Buddy system and Slab allocation.

7. Buddy System
   The buddy system is a memory allocation and management algorithm that manages memory in power of two increments. It also gives us the pros and cons of using it.

8. Page Fault
   The explaination is pretty clear about page fault and also it provides page fault terminology for us

9. Thrashing
   This page gives a great explanation about thrashing, causes of thrashing, effect of thrashing, and some techniques used to handle thrashing

10. Virtual Memory in OS
    A great summarize about Virtual Memory. It gives us a short yet clear explanation.
