Partitions and mounting
A disk can be sliced into many partitions, or a partition can span multiple disks. Every partition can be either "raw", having no file system, or "cooked" containing a file system. Raw disk is used where no file system is appropriate. Raw disk can also hold information required by disk RAID systems, such as bit maps indicating which blocks are mirrored and which have changed and required to be mirrored
When do we write a page from physical memory back to the disk? In general, caches have two broad types of writing policies. One approach is a write-through cache. In this case,
