Real-time operating system

Abbreviated as RTOS, a real-time operating system or embedded operating system is a computer operating system designed to handle events as they occur. Real-time operating systems are commonly found and used in robotics, cameras, complex multimedia animation systems, communications, and have various military and government uses.

Embedded operating systems are stored in a ROM chip instead of a hard drive and contain only the absolutely necessary files for the device it is running on. Because it does not load executable files, it is only capable of running one application at a time.

Many operating systems, such as Windows and Linux, have embedded versions. Other examples include Chimera, Lynx, MTOS, QNX, RTMX, RTX, and VxWorks.
