This is the memory located -within the memory chips, within your computer. This is the -<acronym>RAM</acronym> (for Random Access Memory) you bought when you -purchased your computer.</para> - -<para>The second type of memory, is called virtual or swap memory. This -block of memory, is actually space on the hard drive. The operating -system reserves a space on the hard drive for <quote>swap space</quote>. -The operating system can use this virtual memory (or swap space), if it -runs out of physical memory. The reason this is called -<quote>swap</quote> memory, is the operating system takes some data that -it doesn't think you will want for a while, and saves that to disk in -this reserved space. The operating system then loads the new data you -need right now. It has <quote>swapped</quote> the not needed data, for -the data you need right now. Virtual or swap memory is not as fast as -physical memory, so operating systems try to keep data (especially often -used data), in the physical memory.</para> - -<para>The total memory, is the combined total of physical memory and -virtual memory.</para> - -</sect2> - -<sect2 id="memory-use"> -<title>Memory Information Module</title> - -<para>This window is divided into a top and bottom section</para> - -<para>The top section shows you the total physical memory, total free - physical memory, shared memory, and buffered memory.</para> - -<para>All four values are represented as the total number of bytes, and - as the number of megabytes (1 megabyte = slightly more than 1,000,000 - bytes)</para> - -<para>The bottom section shows you three graphs: </para> - -<itemizedlist> -<listitem><para><guilabel>Total Memory</guilabel> (this is the combination of physical and virtual memory).</para></listitem> -<listitem><para><guilabel>Physical Memory</guilabel></para></listitem> -<listitem><para>Virtual memory, or <guilabel>Swap Space</guilabel>.</para></listitem> -</itemizedlist> - -<para>The green areas are free, and the red areas are used.</para> - -<tip><para>The exact values of each type of memory are not critical, and - they change regularly.
