Virtual Memory, Address Translation, and I/O Models in Operating Systems
Virtual memory extends limited physical RAM by giving each process a large address space translated via page tables and a TLB, while multi‑level tables manage size, and the OS separates kernel and user space, offering blocking/non‑blocking, synchronous/asynchronous, multiplexed I/O, reactor patterns, and zero‑copy techniques to optimize data transfer.
