Accessing local and remote file systems
11.. PPuurrppoossee
_L_i_n_u_x manages all filesystems as a single large tree. This is unlike
_D_O_S, which manages all hard drives and network volumes as a set of
independent units (C: D: E:).
The first partition accessed by _L_i_n_u_x is called the _r_o_o_t. The top-
level directory is called /. The other partitions (and network
volumes) may be installed anywhere in the filesystem tree.
For example, you can set up your _L_i_n_u_x system like this:
+o /D
+o /E
+o /servers/server1/vol1
+o /servers/server1/vol2
+o /servers/server2/apps
+o /servers/server2/util
These directories are called _"_m_o_u_n_t _p_o_i_n_t_s_". They are initially empty.
_L_i_n_u_x will logically install the different partitions and volumes
right there.
All this means is that you have to tell Linux which partitions/volumes
go where.

Your computer may have several hard drives. Each one may have several
subdivisions. These are called partitions. Each of those can be
thought of as a smaller hard drive.
Unless told to do so, Linux won't access those partitions.

Most NFS servers (Generally UNIX servers) have a list of filesystems
available to a user's workstation. You can logically install one
server volume in one empty directory, merely by extending the span of
your local hard drives.

_L_i_n_u_x may have up to 16 swap spaces active at one time. A swap space
is used to extend your computer's RAM. If you don't have a swap, get
one here.
