Show Answer
253. For load-time dynamic linking
  • Load module (application module) to be loaded is read into memory.
  • Some of the linking is postponed until execution time.
  • External reference to target modules remain in the loaded program.
  • None of these
Show Answer
254. In thread schedulling, load sharing is referred to
  • Simultaneous schedulling of threads that make up a single process.
  • Implicit scheduling defined by the assigment of threads to processors
  • A global queue of ready thread is maintained and each processor, when idle, selects a thread from queue.
  • None of these
Show Answer
255. The real time task
  • The tasks that reacts to events that take place in out side world.
  • The tasks that do not reacts to the outside world events.
  • The tasks are independent of the time when it occurs
  • None of these
Show Answer
256. Hard real-time tasks are
  • A real time task that do not require dead line constraints
  • A real time task that requires dead the constraints
  • A task independent to time when it occurs
  • None of these
Show Answer
257. The deterministic operating system
  • where operations are performed with in pre-determined time interval.
  • Where operations can be performed with out pre-determined time interval.
  • The operating time can not be determined.
  • None of these
Show Answer
258. Responsive real time operating system
  • The interruption is acknowledge system operating system response to interrupt.
  • Once the operation starts no interrupt is acknowedge
  • The operation completes in fixed inter of time
  • None of these
Show Answer
259. In multi processor schedulling; A: Gang scheduling, B: Dynamic scheduling, C: Dedicated processor management.; 1- The number of threads in a process can be altered furing the occurs of execution. 2- This provides implicit scheduling defined by the assignment of threads ot processors, 3- it is applied to the simultaneous scheduling of threads that make up a single process.

  • A-3,B-1, C-1
Show Answer
260. In real time computing
  • The result of computation does not depend on the time at which computation is done
  • The result of computation also depends on the time at which computation is done.
  • The results are independent of the time considered
  • None of these
