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 has various military and government uses. Embedded operating systems are stored in a ROM chip instead of a hard drive and contains only the absolute necessary files for the device it is running on, and because it does not load executable files is only capable of running one application at a time. Many operating systems such as Windows and Linux have embedded versions and other examples included Chimera, Lynx, MTOS, QNX, RTMX, RTX, and VxWorks.
