An introduction to Virtual Memory

I myself had some problems grasping what virtual memory is and how it manages memory. After a lot of reading and surfing, I found these resources much more comprehensive than others. So if you want to start to know what virtual memory, page table, TLB, etc., are, I recommend checking out these websites:

• A conscious overview on VM: What is happening underneath VM in detail (Highly recommended)
• Another resource that might come in handy is a series of videos by Dr. Murphy, which is available on YouTube.
• You may also find a bunch of tutorials about OS (including Memory management, kernel programming, and more) here.
