<title>Accessing local and remote file systems
<author>Introduction
<sect>Purpose
<p>
<em/Linux/ manage all file-systems as a single large tree. This
is different from
<em/DOS/ which manage all hard drives and network volumes as a set
of independent unit (C: D: E:).
The first partition accessed by <em/Linux/ is called the <em/root/.
The top-level directory is called <tt>/</tt>. The other
partitions (and network volumes) may be installed anywhere
in the file-system tree.
For example, you can setup your <em/Linux/ system like this.
<itemize>
<item>/D
<item>/E
<item>/servers/server1/vol1
<item>/servers/server1/vol2
<item>/servers/server2/apps
<item>/servers/server2/util
</itemize>
These directories are called <em/"mount points"/. They are
initially empty. <em/Linux/ will logically install the
different partitions and volumes right there.
All of this to tell you that you have to tell which
partitions/volumes go where.
<sect>Local drive
<p>
Your computer may have several hard drive. Each one
may have several subdivisions. These are called partitions.
Each of those can be thought as a smaller hard drive.
Unless told so, Linux won't access those partitions.
So here you are.
<sect>NFS volume
<p>
Most NFS server (Generally Unix server) have a list of
file systems available to user's workstation. You can
logically install one server volume in one empty directory, merely
extending the span of you local hard drives.
<sect>Swap file and partitions
<p>
<em/Linux/ may have up to 16 swap spaces active at one time.
A swap space is used to extend your computer RAM. If you
don't have a swap, get one here.
