Answer Posted / preet baidwan
while any process is in its critical section , any other process that tries to enter its critical section must loop continously in the entry code.this continue looping is clearly a problem in a real multiprogramming system. where a single CPU is shared among many processes. Busy waiting wastes CPU cycles that could have been used by some process in more productive way. This type of semaphore is also called a spinlock.
