What is the difference between real time OS and normal OS?
Difference between GPOS and RTOS. General purpose operating systems cannot perform real time tasks whereas RTOS is suitable for real time applications. Synchronization is a problem with GPOS whereas synchronization is achieved in real time kernel. Inter task communication is done using real time OS where GPOS does not.
