We have provided here the Real time Operating systems MCQ for Computer Science and Engineering Students that will help students revise all important concepts and topics in a short-time but effectively.
Important points to Remember about In Real time Operating system :
- A real-time operating system is an operating system that has been developed for real-time applications.
- As we know in real time operating system user is not important but the processes are very important.
- Generally, your resources are underutilized in order to pay attention to the processes when they require it.
- They are used in environments where a large number of events are processed.
- Some examples of real-time Operating Systems are: VxWorks, Solaris, Lyns OS, and Spectra.
- Many real-time Operating Systems are built for very specific applications such as air traffic control, stock exchanges, refinery control, rolling mill control. Train control, Telecommunications, Integrated manufacturing systems, Production and distribution of electricity, Building control.
- They are used in industrial control, telephone switching, flight control, real-time simulations, military applications, etc.
- Objective is to provide fast response times. Process bursts of thousands of interrupts per second without missing a single event. Process is activated after the occurrence of an event, through interruption.
- Higher priority process expropriates resources. Therefore, priority-based expropriation planning is generally used.
- Less demanding memory management than time sharing, usually processes are permanent residents in memory.
