A system component that provides file caching support for file system drivers.

The portion of an AFS Client machine that communicates with AFS server processes by translating file requests made locally into remote procedure calls. It stores the requested files in a cache on the local disk, from which it makes the files available to local users.

a program on a client machine that accesses files stored in AFS. When a user requests a file, the cache manager retrieves it from the appropriate file server and stores or "caches" a copy of it on the client workstation's local disk for the user to use.

A periodic clean-up process to remove old files to make room for new ones.

A set of modifications to the operating system on a client machine which enables users on the machine to access files stored in AFS. The Cache Manager requests files from the File Server and stores ( caches) a copy of each file on the client machine's local disk. Application programs then use the cached copy, which eliminates repeated network requests to file server machines.
