What is the term busy waiting what other kinds of waiting are there in an OS can busy waiting be avoided altogether explain?
Busy waiting cannot be avoided altogether. Generally, busy waiting is mostly avoidable on uniprocessor machines, but is mostly unavoidable on multiprocessor machines. However, even on multiprocessor machines busy-waiting is best used for very short waits and limited to operating system code.
How many types of operating system processes are there?
Basically there are two types of process: Independent process. Cooperating process.
What is another term for busy waiting?
In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available.
What is the difference between busy waiting and blocking?
Explain the difference between busy waiting and blocking process synchronization. With busy waiting, process keeps testing for condition. With blocking, process gives up CPU and awakened later when condition it is waiting for has become true.
What is busy waiting what is its principle alternative?
7.1. Busy Waiting The alternative to busy waiting is blocking, where the waiting process is suspended an other processes can execute while the process is waiting.
What is a busy waiting and how is it solved?
Answer: Busy waiting means a process simply spins (does nothing but continue to test its entry condition) while it is waiting to enter its critical section. This continues to use (waste) CPU cycles, which is inefficient. Do semaphores solve the problem of process synchronization completely?
What is Busy waiting in operating system?
Busy waiting, also known as spinning, or busy looping is a process synchronization technique in which a process/task waits and constantly checks for a condition to be satisfied before proceeding with its execution.
What is Spin waiting?
Spin Wait. A spin wait that you have to wait until condition for thread is true. Spin Loop. Spin loop is also similar to both of above busy spin and wait spin. It means that threads have to wait for other thread for completing his work.
What is busy waiting in C?
Busy waiting means a process simply spins, (does nothing but continue to test its entry condition) while it is waiting to enter its critical section. This continues to use (waste) CPU cycles, which is inefficient.
What is block waiting?
A process that is blocked is one that is waiting for some event, such as a resource becoming available or the completion of an I/O operation. In a multitasking computer system, individual tasks, or threads of execution, must share the resources of the system.
