title: Where is page table located?
body: <p>I've been studying about paging and page tables. I don't see to understand where page tables are located. 
  In one of the answers from stack exchange(<a href="https://unix.stackexchange.com/questions/487052/where-is-page-table-stored-in-linux">https://unix.stackexchange.com/questions/487052/where-is-page-table-stored-in-linux</a>), it is said that page tables are in kernel address space, which is in virtual memory(from what I understood). 
  However in lecture slides from University of Illinois(<a href="https://courses.engr.illinois.edu/cs241/sp2014/lecture/09-VirtualMemory_II_sol.pdf" rel="noreferrer">https://courses.engr.illinois.edu/cs241/sp2014/lecture/09-VirtualMemory_II_sol.pdf</a>), page tables seem to be in RAM, which is physical memory. 
  Can anyone tell me clearly where the page tables are stored?</p>
  
  <p>Thank you in advance.</p>
