Unit Four Test, CSCI 423, Introduction to Operating Systems, 13-Nov-07

 1)Describe the implementation and operation of a paged MMU.

 2)Describe three ways that Linux automatically manages data movement
   among memory hierarchy components.

 3)Describe how "udev" attempts to solve the scarce-LUT-number
   and hotplug problems.

 4)Contrast Infiniband and PCI-Express (PCIe).
   
 5)Explain the limitation of SSF, explain how the elevator algorithm
   solves this limitation.

 6)Describe the theory of operation of flash memory.
   
 7)Describe the inefficiency of a constant angular velocity (CAV)
   disks, explain how "bit-zone" recordings improves recording
   efficency, and explain how this impacts data density and I/O speed.
     
 8)Describe the rationale and explain how Linux utilities fdisk, parted,
   hdparm, mkfs, dumpe2fs, tune2fs, and mount are used to fully exploit
     
 9)Describe the general evolution of Unix file formats inode, BSD FFS,
   and journaling file systems and give their design tradeoff.
   
10)Define "deadlock" and describe the four conditions for deadlock to
   occur.

Bonus:
   Contrast the Berkeley FFS and IBM's JFS giving their tradeoff. And
   why you would recommend one design over the other.
