Description (
"Capabilities and management of Cache Memory. Cache memory is "
"dedicated or allocated RAM that a Processor searches first for "
"data, before going to \'regular\' memory. CacheMemory is used "
"to speed up the delivery of data to a Processor. It is usually "
"described by its closeness to the Processor (for example, "
"Primary or Secondary Cache). \n"
"If a DiskDrive includes RAM allocated for holding the disk\'s "
"most recently read and/or adjacent data (in order to speed up "
"retrieval), this also would be modeled as CacheMemory. Note "
"that CacheMemory is NOT operating system or application level "
"buffers but actual RAM allocated for caching data for a "
"Processor, from a hard disk, etc." )]
