real time operating systemAbbreviated as RTOS, a real-time operating system or embedded operating system is a computer operating system designed to handle events as they occur.

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.
