It tells -
1) which filesystems are currenly mounted
Code:
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
2) which device files these filesystems belong to
Code:
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
3) What is the mode in which these devices are mounted.

4) which location they are mounted upon.

In linux, the files and folders are located logically in a tree like structure. Although the location of actual data could be different
Code:
                          Root /
                            |
           |                       |                    |          |
      directory1              directory2              file1       mnt
            |                     |                                |
         |        |         |           |                         mydir
   directory1   file1     file1       file2
       |
   |    |     |
file1 file2 file3
Now suppose you have some other devce, for eg. a partition on your hard disc whose device name is /dev/hda5. And which has 2 files and 1 directory.
Code:
                               /dev/hda5
                                  }
                       |           |             |
                  directory1     file1          file2
Now u want to access files on /dev/hda5 partition on your linux system. Then u will need to mount (attach) this /dev/hda5 to the root (/) filesystem at any empty directory (mount point) whjich lies some where on (/) physically to make it available for usage.
Suppose you mount /dev/hda5 to some directory eg mydir in dirctory /mnt, as
A command named mount can be used as
Code:
mount /dev/hda5 /mnt/mydir
So, now your file structure on / will be like this logically
Code:
                          Root /
                            |
           |                       |                    |          |
      directory1              directory2              file1       mnt
            |                     |                                |
         |        |         |           |                         mydir
   directory1   file1     file1       file2                         |
       |                                                   |          |    |
   |    |     |                                         directory1   file1 file2
file1 file2 file3
There are lots of filesystems supported in linux. To know about these filesytems, you may visit this link http://wiki.linuxquestions.org/wiki/Filesystem or search google.
