In C , a thread can be terminated using Abort method. Abort throws ThreadAbortException to the thread in which it called. Due to this exception, the thread is terminated. Suspend method is used to suspend thread which can be restarted by using resume method. Why is Thread. Because it is inherently unsafe. Stopping a thread causes it to unlock all the monitors that it has locked. There is no way to gracefully kill a thread. It is simple. Use Thread. Join is a synchronization method that blocks the calling thread that is, the thread that calls the method until the thread whose Join method is called has completed.
Use this method to ensure that a thread has been terminated. The caller will block indefinitely if the thread does not terminate. What decides thread priority?
Explanation: Thread scheduler decides the priority of the thread execution. This cannot guarantee that higher priority thread will be executed first, it depends on thread scheduler implementation that is OS dependent.
If two threads of the same priority are waiting for the CPU, the scheduler arbitrarily chooses one of them to run. The chosen thread runs until one of the following conditions is true: A higher priority thread becomes runnable. It yields, or its run method exits. Every thread has a priority which is represented by the integer number between 1 to The value of it is 1. What will happen if two thread of the same priority are called to be processed simultaneously?
Explanation: In cases where two or more thread with same priority are competing for CPU cycles, different operating system handle this situation differently. Which two are valid constructors for Thread? Explanation: 1 and 2 are both valid constructors for Thread. It might be as simple as round-robin, based on the order the thread arrived on the ready queue. A process can have anywhere from just one thread to many threads.
When a process starts, it is assigned memory and resources. Each thread in the process shares that memory and resources. In single-threaded processes, the process contains one thread. A processor executes threads, not processes, so each application has at least one process, and a process always has at least one thread of execution, known as the primary thread.
A process can have zero or more single-threaded apartments and zero or one multithreaded apartment. Creating a thread is expensive, and the stack requires memory. More commmonly IMO , OS level threads are expensive because they are not used correctly by the engineers — either there are too many and there is a ton of context switching, there is competition for the same set of resources, the tasks are too small.
If your thread usage peaks at 3, then is too much. If it remains at for most of the day, bump it up to and see what happens. Like a traditional process i. Each thread has its own stack. Since thread will generally call different procedures and thus a different execution history. This is why thread needs its own stack.
Heap — Since global variable is stored in the heap, heap is shared among threads. As you state, threads share the same address space. Thus each thread has the same access to the address space as does any other thread. Generally mode level protection is designed to prevent user access to the shared system range of the logical address space.
A process is an active program i. A process is a program under execution i.
