Jun 24, 2024 · Very similar to Process Control Blocks (PCBs) which represents processes, Thread Control Blocks (TCBs) represents threads generated in the system. It contains information about the threads, such as it's ID and states. The components have been defined below: Thread ID: It is a unique identifier assigned by the Operating System to the thread when it
Jun 28, 2024 · The operating system doesn’t require allocating a new memory map for a new thread since it has already created one for the underlying process, and the thread can use it freely. There’s no need to create new structures to keep track of the state of open files. However, we need to make threads access the shared resources in a safe way.
4 days ago · The algorithm for finding out whether or not a system is in a safe state can be described as follows: 1) Let Work and Finish be vectors of length ‘m’ and ‘n’ respectively. Initialize: Work = Available. Finish [i] = false; for i=1, 2, 3, 4….n. 2) Find an i such that both. a) Finish [i] = false. b) Needi <= Work.
4 days ago · Livelock is a special case of resource starvation; the general definition states that a specific process is not progressing. Livelock: Deadlock: var p = new object(); lock(p) { lock(p) { // deadlock. Since p is previously locked // we will never reach here... A deadlock is a state in which each member of a group of actions, is waiting for some ...

Jun 17, 2024 · Race Condition. A race condition occurs when two threads in a program are trying to update the same value at the same time. If the operating system decides to interrupt one thread at just the wrong time, then a race condition occurs and the value could be given an incorrect value. Let’s look at the simplest form of a race condition.
