Using compressed swap space with zram or zswap also offers advantages for low-end hardware devices such as embedded devices and netbooks. Such devices usually use flash-based storage, which has limited lifespan due to write amplification, and may also use it to provide swap space. Using zram or zswap reduces the swap usage, which effectively ...
SWaP (space, wattage and performance) is a Sun Microsystems metric for data centers, incorporating power and space: = Where performance is measured by any appropriate benchmark, and space is size of the computer. [29]
A disk quota is a limit set by a system administrator that restricts certain aspects of file system usage on modern operating systems. The function of using disk quotas is to allocate limited disk space in a reasonable way. [1]
With DOS, Microsoft Windows, and OS/2, a common practice is to use one primary partition for the active file system that will contain the operating system, the page/swap file, all utilities, applications, and user data. On most Windows consumer computers, the drive letter C: is routinely assigned to this primary partition. Other partitions may ...
Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".
In operating systems it's the act of managing disk-backed data in main memory. The terms "paging in" and "paging out" respectively refer to loading and dropping of disk-backed pages from main memory (usually the page cache, but also applied to swap space — I am not sure whether this is correct usage or not).

A memory leak can cause an increase in memory usage and performance run-time, and can negatively impact the user experience. [4] Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to ...
