- Question
Explain the popular multiprocessor thread-scheduling strategies.
- Correct Answer
- Load Sharing: Processes are not assigned to a particular processor A global queue of threads is maintained Each processor, when idle, selects a thread from this queue Note that load balancing refers to a scheme where work is allocated to processors on a more permanent basis Gang Scheduling: A set of related threads is scheduled to run on a set of processors at the same time, on a 1-to-1 basis Closely related threads / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching Group scheduling predated this strategy Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program Processors are chosen from the available pool Dynamic scheduling: The number of thread in a program can be altered during the course of execution

Correct Answer: foreign keys.
Correct Answer: the processing speed depends on DATA BUS WIDTH
Correct Answer: Repetitive Strain Injury
Correct Answer: FIFO (First In First Out) stack is used in 8086 In this type of Stack the First Stored Information is retrieved first
Correct Answer: Object Repository means not a collection of objects it's a common repository for all the people (testing, developers) for seeing all the data in single login for example QA wants to see 5 testers works then he goes to each person login and see the data It's very difficult job for this we can use Object Repository
Correct Answer: LIFO (Last In First Out) stack is used in 8085 in this type of Stack the last stored information can be retrieved first
Correct Answer: Graphical User Interface
Correct Answer: The OSI Model is used as a reference model The primary reason the OSI model was created was so that different networks could inter-operate Hence, different networks could communicate
