a) Mutual exclusion: If a process is implementing in the critical section, then no other process is able to be executed in the critical section.
b) Progress: If no process is implementing in the critical section and there are processes that wish to enter the critical section, after that only those process that are not executing in the non critical section can participate in the decision of which will enter its critical section next, and this section cannot be postponed indefinitely
c) Bounded waiting: There subsist abound on the number of times that other processes are permitted to enter their critical sections after a process has made a request to enter its critical section and before that request is granted. This bound avoid starvation of any single process.
Synchronization can be achieved by means other than locks and condition variables. One alternative is semaphores. A semaphore is used to regulate traf?c in a critical section. A se
Linked list allocation: At this time the blocks are stored using linked lists. The block size require not be the same. Thus internal fragmentation is avoided. Consider
Convert the following from hex to binary and draw it on the memory map. RAM = 0000 -> 00FF EPROM = FF00 -> FFFF Answer: 0000 0000 0000 0000 (0) RAM sta
Explain system-wide open-file and per-process open-file The system-wide open-file table have a copy of the FCB of each open file, as well as other information. The per-pr
What are race conditions? Race conditions are problems that take place due to the sharing of the same file by several processes. In such a case none of the processes is able to
The swapper work s on the biggest scheduling priority. Initially it will look for any sleeping process, if not get then it will see for the ready-to-run process for swapping. Bu
Explain the Peterson's solution for the critical section problem? In Peterson's solution two variables a) flag and b) turn are used as shared variables. If the both shared vari
Assume that P A , P B and P C are three distinguished program s . When P A is executed, it needs 10 ticks to complete its execution and it forks new processes executing P B at tick
