What are the threads called?
tl;dr: They're called threads because thread is an apt metaphor. When you start a thread, you rely on the operating system to allocate processing time so that your thread can execute. While your thread is executing, the processor (or core) is placing all of its attention on your thread.
What do you mean by multithreaded program Explain the life cycle of a thread?
Thread exists in several states. A thread just created is in the born state. When the threads start method is called, it enters the runnable (ready) state. Then the system assigns a processor to the thread. A thread enters the dead state when its run method completes or terminates for any reason. When a sleep method is called in a running thread, that thread becomes ready after the designated sleep time expires. Even if a processor is available, sleeping thread can not use it. A running thread can enter a blocked state.
Which CPUs have extra hardware built in to allow more than one thread to be processed at the same time on a single CPU?
Multicore
Is it true that one drawback of multiprocessing is that it tends to reduce a computers processing speed?
Yes, this is true to a point. When you do multitasking, all the programs you are running are sharing the processing power. So more programs run than in a single-thread operating system, but they may run a little slower.However, with modern hardware, this is more negligible. For instance, if you have a multicore processor, and you have no more running processes than cores (including virtual hyperthreading cores), then it would be about the same as running a single program on a single core, assuming the same amount of operating system overhead.
How hyperthreading processor is different from other traditional processors?
A traditional processor normally isn't 100% active. There are some parts of the processor that specialise in different processes, and they can only process one thread (or task) at a time, so when it is doing one process, other parts of the processor used for other things remain idle. A hyperthreading processor is seen in operating systems as 2 CPUs so it is given 2 threads (or tasks if you like) at once. The processor then processes one thread, and uses inactive parts of the processor to process the other thread.
To use a needle and thread?
To use a needle and thread could be called sewing.To use a needle and thread could be called quilting. To use a needle and thread could be called embroidery. To use a needle and thread could be called suturing.
What is thread holder?
the holder of a thread is called a spool
What is the main advantage of multiple programming?
The main advantage is that multiple programs can run concurrently on the same processor. Given that there is only one processor, the programs cannot execute simultaneously as they would on a multi-processing system with independent CPU cores. Instead, each program must periodically yield control back to the system in order to allow other threads of execution to make use of the CPU. Modern operating systems can do this automatically, periodically saving the current thread's "state" and switching to the next thread of execution in the queue.
What is purpose of interrupt?
The interrupt of a proces or thread on the processor has been introduced to avoid a big proces/thread to consume too much of the processor power and therefore "starving" other processes. Interruption is also used to stop crashed processes which are running an endless loop or are waiting for resources for too long. By interrupting a process, the processor can continue with another process and pick up later with the big process when it has waited for his turn again and by this sheduling processes to run on the processor more efficiently. An interrupt will be called after x time or x cycles, which depends from machine (computer) to machine (computer).
The thread-like structures which are the building blocks of fungi are called?
Thread like structures in fungi are called hyphae .
What is flickering?
There is a visible flicker when viewing the applet. This is usually caused by an applet that utilizes a lot of processing power but is not threaded, hence the entire program runs on one processing thread.
Why java called as multithreaded programming?
Java is called multithreaded because it allows the programmer to define multiple threads of execution manually. The main program would continue to execute as one thread and we can speed up the processing by declaring individual threads. Threads in Java can be created in two ways: 1. By extending the Thread class & 2. By implementing the Runnable interface
