Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

page offset

The low part of an address, which says which byte inside the page; translation never changes it.

The page offset is the low p bits of a virtual address (12 for 4 KiB pages); it is copied unchanged into the physical address.

Examples

  • With 4 KiB pages, the address 0x12345 has page offset 0x345, its low 12 bits.
