If the CPU supports virtual memory, the operating system doles out different groups of addresses (called address spaces) to operating system components and any executing applications.

Paging Virtual memory breaks programs into fixed-size blocks called pages. If a computer has abundant physical memory, the operating system loads all of a program's pages into RAM.

OS X Lion's FileVault technology may seem to make encrypted virtual memory redundant, but maintaining encryption even with FileVault 2 enabled is likely a good idea.

Linux novices often find virtual memory mysterious, but with a grasp of the fundamental concepts, it's easy to understand. With this knowledge, you can monitor your system's memory utilization using ...

In OS X one aspect of the virtual memory system is the disk cache, which is used to overcome the relatively slow speed of the hard drive by mirroring its filesystem blocks in memory.

In Part 4, the author described the various techniques used for memory management in an embedded OS. In this installment, the author describes Linux memory management and the kernel memory space.

Virtual machine memory management is still one of the most tactical areas of virtualization administration. Something I'm watching closely is how new operating systems will impact my daily practice.

Understanding Linux memory management—page tables, swapping, and memory allocation—enables system administrators and developers to optimize performance and troubleshoot issues effectively. With tools ...

Decreased kswapd (which manages virtual memory) usage should return improved CPU performance, which is great for any device from low-end models to flagships, but it's the low-memory kill numbers ...
