A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name). [ 1 ]
In Windows NT operating systems, the System Idle Process contains one or more kernel threads which run when no other runnable thread can be scheduled on a CPU. In a multiprocessor system, there is one idle thread associated with each CPU core. For a system with hyperthreading enabled, there is an idle thread for each logical processor.

The free software and open-source Unix-like operating systems running the X Window System (such as Linux and FreeBSD) use XScreenSaver almost exclusively. [citation needed] On those systems, there are several packages: one for the screen-saving and locking framework, and two or more for the display modes, divided somewhat arbitrarily.
A pop-up in the top of the screen after the camera recognizes a QR code A screen hotspot , in computing , provides a special area on the display screen of a computer for hyperlinking or for other GUI -based activity (such as re-direction , pop-up display, macro execution, etc.).
Many operating systems, for example Windows, [1] Linux, [2] and macOS [3] will run an idle task, which is a special task loaded by the OS scheduler on a CPU when there is nothing for the CPU to do. The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority.
The second is the full-screen mode. In Windows XP and earlier, the full-screen console uses a hardware text mode and uploads a raster font to the video adapter. This is analogous to a text system console. This early full-screen mode only supports VGA-compatible text modes, giving it a maximum character resolution of 80 columns by 28 rows. [2]
