What are the popular multiprocessor thread scheduling strategies?
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.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.

What is threading in OS?
Threads are the actual path of execution of a program.
What is the difference between process and thread in net?
A process is a collection of threads that share the same virtual memory. A process has at least one thread of execution, and a thread always run in a process context. Thread is used to allocate and distribute the CPU work scheduling, many programs a re assigned to different threads and they are most of the time independent of each other. Eg: We can open many instance of MS word and MS Excel in our PC, all are monitored and managed by threads. Process is nothing but a program in execution, many threads can run under a process or many thread can combined under the one thread.
What is the similarities a computer process and thread?
Both processes and threads are fundamental units of execution in a computer system, allowing for multitasking and efficient resource utilization. A process is an independent program in execution with its own memory space, while a thread is a smaller unit of a process that shares the same memory space as other threads within that process. Both can execute concurrently, enabling better performance and responsiveness in applications. Additionally, they both rely on the operating system for scheduling and management.
What is the purpose of Java sleep?
It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.It pauses the execution of the program (or of the thread where it is invoked, if you have multiple threads), for the specified time.
What is colored-threads in low power?
Colored threads in low power computing refer to a method of managing and scheduling tasks in multi-core processors by assigning different "colors" to threads based on their priority or resource requirements. This approach enhances efficiency by allowing the system to allocate resources dynamically, ensuring that high-priority tasks receive the necessary processing power while minimizing energy consumption. By optimizing thread execution and management, colored threads can contribute to improved performance in low-power environments, such as mobile devices and embedded systems.
How process and threads relate to CPU architecture?
A process is a program in execution,it needs resources like CPU time,memory,files and i\o devices to accomplish its task. Threads are lightweight process
Animal cells have blue threads during mitosis. Each individual component of the doublet is called a..?

What is a thread in computers?
Execution context within a process is called Thread. Threads run, process does not. Every process starts with one thread.
How many threads can core 2 duo processor execute simutaneously?
Since the core 2 duo processor has two execution units, it can execute two threads simultaneously. (If you said quad instead of duo, the answer would be four.)
What mean by multithreaded program?
A multithreaded program is one that has multiple threads in execution. They may execute parallel to one another or totally without relation to one another. In Java you can create multithreaded programs using Java threads.
