Memory management — the essentials
- Virtual memory lets each process act as if it has its own large, contiguous address space.
- Paging uses fixed-size blocks to reduce external fragmentation; the TLB caches page-table lookups.
- Demand paging loads pages only when needed — trade-off: page-fault latency vs. memory use.
Audio lesson · 6 min 12 s
Why does demand paging reduce initial load time?
Only pages actually referenced are brought into physical memory, so startup avoids bulk I/O.

Active recall beats re-reading
What 100+ studies on memory actually say.
Active Recall vs Re-Reading: The Study Method Top 1% Students Use
If there is one study method backed by 100+ peer-reviewed studies, it is active recall. If there is one method students actually use, it is re-reading. Here is why that mismatch kills grades, and a 10-minute protocol to fix it.
