Unit 3: File System Hierarchy




          File manager: It is an integral part of the operating system which is responsible for the maintenance   notes
          of secondary storage.
          File system: It is a set of abstract data types that are implemented for the storage, hierarchical
          organization, manipulation, navigation, access, and retrieval of data.
          File: It is a named collection of data stored in a device.

          Flash file system: It is a file system designed for storing files on flash memory devices.
          Flat file system: It is a file system where no subdirectories are present and everything is stored at
          the same (root) level on the media, be it a hard disk, floppy disk, etc.

          Network  file system: It is a file  system that acts as  a client for  a remote file  access  protocol,
          providing access to files on a server.

          Fill in the blanks:
          1.   A  flash  file  system  is  a  file  system  designed  for  storing  files  on  ……………  memory
               devices.
          2.   The ……………. contains pointers to the various blocks.
          3.   In a flat file system, there are no ……………. -everything is stored at the same (root) level
               on the media, be it a hard disk, floppy disk, etc.
          4.   The ……………… file would contain pointers to secondary index files, which would point
               to the actual data items.

          5.   In two level directory structure one is ………………. directory and the other is user file
               directory.
          6.   Stopping ……………….. in this case would require stopping two systems—nfsfs and nfs.
          7.   A ………………is a file system designed for the storage of files on a data storage device,
               most commonly a disk drive.
          8.   ……………….file systems are one technique used to introduce transaction-level consistency
               to file system structures.
          9.   The ………………….. directory specifies the home or login directory for the account.

          10.   Information in the file is ……………… in order, one record after the other.
          11.   ……………….. processing introduces the guarantee that at any point while it is running.
          12.   File systems share much in common with database technology, but it is debatable whether
               a file system can be classified as a ……………………

               fame.
          14.   The ………………… system contains information about the state of processes and threads
