Q. Palm OS provides no signifies of concurrent processing. Discuss three major complications that concurrent processing adds to an operating system.
Answer:
a. A method of time sharing should be implemented to allow each of several processes to have access to the system. This method involves the pre-emption of processes that don't voluntarily give up the CPU (by using a system call, for instance) as well as the kernel being re-entrant (so more than one process may be executing kernel code concurrently).
b. Processes as well as system resources should have protections and must be protected from each other. Any given process must be limited in the amount of memory it can use and the operations it can perform on devices like disks.
c. Care should be taken in the kernel to prevent deadlocks between processes consequently processes aren't waiting for each other's allocated resources.
