Virtual Memory Explained: Address Spaces, Paging, and How malloc Gets Memory

A new post in the Operating Systems Explained series covers virtual memory, the mechanism that gives each process its own address space. It explains paging and page tables, the translation lookaside buffer (TLB), and how page faults and swap are handled. The article also describes how system calls such as mmap and brk, along with malloc, obtain memory from the operating system. It connects back to an earlier post in the Computers Explained series, showing how identical addresses in two processes map to different physical frames under hardware enforcement.
