Data
1 word (W) = 1 byte (B)
Logical address = 232 B
page size = 4 KB = 212 B
page table entry (PTE) = y B
Formula:
Page table size (PTS) = number of pages × y
Calculation:
number of pages = \(\frac{{{2^{32}}}}{{{2^{12}}}} = {2^{20}}\)
Page table size (PTS) = number of pages × y
\(PTS = {2^{20}} \times 4B\)
∴ PTS = 4 MB
Important points
1 MB = 220 B
where B stands for byte
