hole n.
A region in an otherwise flat entity which is
not actually present. For example, some Unix filesystems can store
large files with holes so that unused regions of the file are never
actually stored on disk. (In techspeak, these are referred to as
`sparse' files.) As another example, the region of memory in IBM
PCs reserved for memory-mapped I/O devices which may not actually
be present is called `the I/O hole', since memory-management
systems must skip over this area when filling user requests for
memory.
