Hi,All.
This is my first time to come to here.
I have some questions about the linux system involved with some mathmatical
questions.
For example, they may include "File Access and Allocation Methods" or Demand Paging.
Let me hold a question,
"
File Access and Allocation Methods.
(a) A UNIX inode has 15 block pointers. Let the first 12 be direct pointers and the other three be single, double and triple indirect pointers, respectively. Furthermore, let disk blocks be 512 bytes in size.
Q1: If block pointers are 32-bits, what is the maximum file size that can be accessed with this system?
Q2: If a file is 51336 bytes in size, how many block transfers are required to access and then bring the file from disk into main memory.
(b) Suppose a file is 64MB, disk blocks are 512 bytes, and block pointers are 32 bits. How much space would be required in a FAT(File Allocation Table) for this file?
"
Should I ask these questions here or someone can tell me If other forums
can help me deal with these questions?
Appreciate it!
