Storage mode

I learn the operating system, the book said storage page, section type storage, segment paged memory, a memory address assembly, good understanding, if paging storage, assembly is how to access the physical address?
And the file system, operating system is how to partition a file?

This thing on this question is hard to explain, I suggest you look at the <<Linux kernel completely analysis of > > written by Dr. Zhao Jiong, the fourth chapter 8086 protected mode programming that block.. You'll understand... The so-called what section with paging is maintaining some corresponding table, such as CS register value inside the corresponding different significance
, In real mode, that is the section base, the physical address is behind a bit offset plus, but enter the protected mode, the meaning is different, see you will understand
Then the file system specific words I forgot, I study the 0.12 kernel, now already lose one's beyond recognition, are interested can study together

The landlord said storage should be mainly refers to the memory read and write, if you want to know, first of all should know CPU evolution, from the beginning of the classic INTEL8086 CPU, how to support memory? To 286386, then the Pentium, Pentium etc. Memory and CPU address signal lines, etc. Address line determines the memory addressing range, from 16, 20, 32, now the mainstream 64. As the hardware is more and more advanced, people also requires that the computer can have more functions, multi task time-sharing operation, and so on, are required to change the memory access. So there is real mode, protected mode paging and segmentation. To speak up, also have a lot of things, in fact I aimlessly, beside the point, no response to the landlord, ha ha, as upstairs said, or go back to have a look how serious the book.
