Explain the Resource Ownership by Platform
Ownership of data items may further be complicated by concepts defined in certain operating systems. Each operating system defines "process" and "thread" differently and each has different mechanisms for spawned threads or processes to inherit resources. Consequently, resource ownership differs on a per-platform basis.
ADVANTAGES AND INCONVENIENCES OF KLT Advantages: the kernel be able to simultaneously schedule many threads of the same process on many processors blocking
Dynamic scheduling : The number of thread in a program may be changed during the course of operation. Dynamic priority scheduling is a kind of scheduling algorithm in which the pr
Multi-level page tables are tree-like structures to hold page tables. As an example, consider a two- level page table, again on a 32-bit architecture with 212 = 4 kbyte pages. Now,
Explain about deadlock detection? In deadlock situation, the system must provide An algorithm that verifies the state of the system to verify whether a deadlock has occu
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
What are a safe state and an unsafe state? Answer: A state is safe if the system can allocate resources to every process in some order and still avoid a deadlock. A system is
Present your own fully documented and tested programming example illustrating the prevention of a data race in a parallelised program. This is an example where total number of p
As mentioned above, page tables, are lookup tables mapping a process' virtual pages to physical pages in RAM. How would one implement these page tables? The most straightforward
