Suppose we want a process to wait until a condition B holds. No busy waiting means that the process has to wait on a semaphore (or whatever synchronization construct we happen to be using). It cannot wait by executing a while loop in which it repeatedly checks B, as in: while not B do skip.

In informatica, e in particolare nei sistemi software concorrenti, l'espressione busy waiting o busy wait (letteralmente "attesa impegnata", più spesso tradotto come "attesa attiva") indica una tecnica di sincronizzazione per cui un processo o un thread che debba attendere il verificarsi di una certa condizione (per esempio la disponibilità di input dalla tastiera o di un messaggio

Busy waiting is a term used in operating system development and here especially process synchronization.When two or more processes want to enter the same critical section, something has to be done to prevent more than one process from entering it.

What is busy wait? | Practice, It means the processor is essentially spinning its wheels doing nothing waiting for an event to take place. In an embedded system,  

The repeated execution of a loop of code while waiting for an event to occur is called busy-waiting. The CPU is not engaged in any real productive activity during this period, and the process does not progress toward completion.

Busy waiting

We can introduce a Boolean variable called mutex that is set to true when an activity is in a critical section, to false otherwise. A process executes the following code before it enters a critical section: while mutex do do nothing end; mutex <- true; busy waiting 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. Oh, but we are far from done.

Busy waiting

However, busy waiting is not the optimal allocation of resources because it keeps CPU busy all the time in checking the while loops condition continuously although the process is waiting for the critical section to become available.

Mutual Exclusion - If process P i is executing in its critical section, then no other processes can be executing in their critical sections 2.
