Question

Explain real time operating system

Answer 1

A real-time operating system (RTOS) is an operating system  (OS) intended to serve real time applications that process data as it comes in, typically without buffer delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time. A real time system is a time bound system which has well defined fixed time constraints. Processing must be done within the defined constraints or the system will fail. They either are event driven or time sharing.

Answer 2

Explanation:

• A "real-time operating system" is an "operating system" meant to provide "real-time applications" which process the data as and when comes in, generally without any buffer delays.
• The time required for processing is calculated in tenths of seconds or shorter stepping of time.
• The real-time system means that the system is subjected to real-time, i.e., response from the system should be assured within a given timing constraint or the system must meet the given deadline.
