interpretation allows the operating system to store system-defined information in the
remaining bits. Information typically stored includes the reason for the invalid encoding
(tables paged out, region unallocated, etc.) and possibly the disk address for nonresident
tables. Figure 3-16 illustrates an address translation table in which only a single page
table (table $15) is resident; all other page tables are not resident.
