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 will only run 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.
