Top 10 List of Week 05

1. How computer memory works
   Like the title, this video tells us how computer memory works on our computer. It says that our memories helping us remember our past, learn and retain skills, and plan for the future. And for the computers, memory plays much the same role. This video also provides great animation to help us understand.

4. Will More RAM Make your PC Faster??
   Do we really need a really big RAM to have a high resolution gaming or 4K video editing? When we ask about how much do we need, as always the answer is, it depends. In this video, they tested a variety od workloads to compare. See more on this video about the details.

5. Thrashing in OS
   When a program need space larger than RAM, the OS will try to allocate space from secondary memory and behaves like it has that much amount of memory by serving to that program or we call it as virtual memory. To know about thrashing we first need to know what is page fault and swapping, so they tell us about that first and then about thrashing, the effects of thrashing, and techniques to handle thrashing.

6. Virtual Memory in OS: What is, Demand Paging, Advantages

Then entering to demand paging, about what is demand paging, types of demand paging and each explanation, how it works, and also its advantages-disadvantages.

   It contains explanations about two strategies for managing free memory that is assigned to kernel processes, such as buddy system and slab system. Mainly discusses about each definition, types, why we use it, example, advantages, and disadvantages.

8. What are the Page Replacement Algorithms?
   This website introduces us the concept of page replacement, which is used in memory management. It tells us the definition, need, and various algorithms related to page replacement with each examples and illustration to help us understand.

9. Windows’s Virtual Address Space: A Short MSDN Story
   Here they tell us about virtual address space and physical storage, page state, scope of allocated memory, memory protection, copy-on-write protection, and some other subtopics.

10. Virtual Memory In a Comic
    Just want to chill out and freshen my mind while searching my weekly top 10 list. This time is a comic about virtual memory. The drawing somehow look interesting to me. The main idea of virtual memory can still be delivered through the drawing and gives me an overview about it.
