The core idea of ReadyBoost is that a flash memory (e.g. a USB flash drive or an SSD) has a much faster seek time than a typical magnetic hard disk (less than 1 ms), allowing it to satisfy requests faster than reading files from the hard disk. It also leverages the inherent advantage of two parallel sources from which to read data, whereas ...
Virtual memory makes application programming easier by hiding fragmentation of physical memory; by delegating to the kernel the burden of managing the memory hierarchy (eliminating the need for the program to handle overlays explicitly); and, when each process is run in its own dedicated address space, by obviating the need to relocate program code or to access memory with relative addressing.
Unix systems, and other Unix-like operating systems, use the term "swap" to describe the act of substituting disk space for RAM when physical RAM is full. [18] In some of those systems, it is common to dedicate an entire partition of a hard disk to swapping. These partitions are called swap partitions. Many systems have an entire hard drive ...
Some utilities prevented DLLs from allocating memory here, leaving more space for user programs. This was a standard technique also used by other memory optimization tools. [ 7 ] SoftRAM also claimed to increase the amount of virtual memory available by compressing the pages of virtual memory stored in the swap file on the hard disk, which has ...
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk. The RAM disk is reloaded ...
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

PSE-36 — an alternative to PAE on x86 processors to extend the physical memory addressing capabilities from 32 bits to 36 bits; PCI hole; Protection ring; RAM drive — a use for remapped RAM; Virtual memory — which governs the memory available to processes User space — and kernel space, which imposes another limit
