The TurnKey Linux Virtual Appliance Library is a free open-source software project which develops a range of Debian-based pre-packaged server software appliances (also called virtual appliances). Turnkey appliances can be deployed as a virtual machine (a range of hypervisors are supported), in cloud computing services such as Amazon Web ...
Location of the "O(1) scheduler" (a process scheduler) in a simplified structure of the Linux kernel. An O(1) scheduler (pronounced "O of 1 scheduler", "Big O of 1 scheduler", or "constant time scheduler") is a kernel scheduling design that can schedule processes within a constant amount of time, regardless of how many processes are running on the operating system.
The Completely Fair Scheduler (CFS) was a process scheduler that was merged into the 2.6.23 (October 2007) release of the Linux kernel. It was the default scheduler of the tasks of the SCHED_NORMAL class (i.e., tasks that have no real-time execution constraints) and handled CPU resource allocation for executing processes , aiming to maximize ...
HASP bypassed most operating system services with code specially tailored for efficiency. HASP operated as a single operating system task [1] and used cooperative multitasking internally to run processors to perform tasks such as running card readers, printers, and punches, managing the spool files, communicating with the system operator, and driving multiple communication lines for remote job ...
CUPS was quickly adopted as the default printing system for most Linux distributions. In March 2002, Apple Inc. adopted CUPS as the printing system for Mac OS X 10.2. [8] In February 2007, Apple Inc. hired chief developer Michael Sweet and purchased the CUPS source code. [9] On December 20, 2019, Michael Sweet announced on his blog that he had ...
A dedicated program, the spooler, maintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. Conversely, for slow input peripherals, such as a card reader , a spooler can maintain a sequence of computational jobs waiting for data, starting each job when all of the relevant input is available; see batch processing .

udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
