A compact operating system is using a $32-$bit CPU that is attached to $4$GiB of main memory $(\text{'}$DRAM$\text{'}).$ Its PL table is of length $64.$ The datatype of an element of PL is an address of Main Memory. All PL entries are NULL with the exception of PL $[1],$ PL $[22],$ PL $[33],$ PL$[44].$ The latter are as follows

PL$[1]=0$X$00$AAB$000$

PL$[22]=0$X$00$AABA$00$

PL$[33]=0$X$00$AAC$000$

PL$[44]=0$X$00$AACA$00$
