sentence not very straight forward "physical addresses can be though of the values that go to physical RAM index wires"

Hello,

I am reading x86-paging and thank you for excellent write-up. But I do have a question on a small sentence and hope you can make more clear. Thank you

Best,

Hi there,

physical addresses can be though of the values that go to physical RAM index wires.

Memory can be thought of a box linked to the CPU box with input address wires, and data wires, have a look at this image: http://www.mathcs.emory.edu/~cheung/Courses/255/Syl-ARM/4-intro/bus-width.html

By "index wire" I meant address wires more precisely, AKA "address bus".
