In computing, a devicetree (also written device tree) is a data structure describing the hardware components of a particular computer so that the operating system's kernel can use and manage those components, including the CPU or CPUs, the memory, the buses and the integrated peripherals.
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes , or to reboot a computer without corrupting the filesystem . [ 1 ]
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.
A 104-key PC US English keyboard layout with System request circled. System Request (SysRq or Sys Req) is a key on personal computer keyboards that has no standard use. Introduced by IBM with the PC/AT, it was intended to be available as a special key to directly invoke low-level operating system functions with no possibility of conflicting with any existing software.
In computing, the menu key (≣ Menu), or application key, is a key with the primary function to launch a context menu with the keyboard rather than with the usual right-mouse button. [1] It was previously found on Microsoft Windows -oriented computer keyboards and was introduced at the same time as the Windows logo key .
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .

Evdev and libevdev form a prominent part of the Linux API.. evdev (short for 'event device') is a generic input event interface in the Linux kernel and FreeBSD. [1] It generalizes raw input events from device drivers and makes them available through character devices in the /dev/input/ directory.
