It is mostly used by device drivers waiting for disk or network IO (input/output). When the process is sleeping uninterruptibly, signals accumulated during the sleep will be noticed when the process returns from the system call or trap. In Unix-like systems the command 'ps -l' uses code "D" for the uninterruptible sleep state of a process. [9]
On the other hand, a system in sleep mode still consumes power to keep the data in the RAM, and thus cannot last indefinitely, as hibernation can. Detaching power from a system in sleep mode results in data loss, while cutting the power of a system in hibernation has no risk; the hibernated system can resume when and if the power is restored.
Microsoft Windows 2000 and later support sleep at the operating system level (ACPI S3 state) without special drivers from the hardware manufacturer, except of video adapters. Windows Vista's Hybrid sleep feature saves the contents of volatile memory to hard disk before entering sleep mode. If power to memory is lost, it will use the hard disk ...

In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
