CDS: The information that a CDS clerk stores locally to optimize name lookups. The cache contains attribute values resulting from previous lookups, as well as information
about other clearinghouses and namespaces. The cache is written to disk periodically so that it can survive a system reboot. See also copy.
DFS: A reserved amount of disk or memory space on a DFS client machine. The DFS Cache Manager uses the cache to temporarily store files or parts of files retrieved from DFS
File Server machines so that future access time and network load are reduced. DFS uses a cache-consistency mechanism (token- passing) to guarantee that the source and cached data are consistent.
