Document Summary

One of the most important tasks that the os performs is the management of a co(cid:373)puter"s (cid:373)e(cid:373)or(cid:455) resources. The os is responsible for organizing and remembering where data have been placed in memory so that they can be retrieved and used. The storage task is complicated by the fact that the data that constitute a single file may not be physically located sequentially. The os is responsible for assigning data a place in storage and for remembering those locations. Many os rely on a device called a file allocation table (fat) to index where data are stored. The fat keeps a record of the locations of all the particular bytes that form a file. When you delete a file, the information is not immediately removed from the disk. Instead, the os simply updates the database keeping track of files on the disk to acknowledge that the file is no longer needed.
