!!! Overview
[{$pagename}], sometimes also called disk [cache], is a transparent [cache] for the pages originating from a secondary storage device such as a hard disk drive (HDD). 

The [Operating System] keeps a [{$pagename}] in otherwise unused portions of the main [memory] ([RAM]), resulting in quicker access to the contents of cached pages and overall performance improvements. 

[{$pagename}] is implemented in kernels with the paging memory management, and is mostly transparent to [applications].
