Real Time Operating System (RTOS)

               In general, an operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer.  An RTOS performs these tasks, but it is also specially designed to run applications with very precise timing and a high degree of reliability.  This can be especially important in measurement and automation systems where downtime is costly or a program delay could cause a safety hazard (post dangers/disasters).
