Question 48
|
A counting semaphore was initialized to 10. Then 6P (wait) operations and 4V (signal) operations were completed on this semaphore. The resulting value of the semaphore is
|
0
|
|
|
8
|
|
|
10
|
|
|
12
|
Question 48 Explanation:
Let the semaphore be S which is initially 10.
S = 10
Now 6P operations and uv operations were completed on this semaphore. So final value of S will be
S = 10 – 6 + 4 = 8
S = 10
Now 6P operations and uv operations were completed on this semaphore. So final value of S will be
S = 10 – 6 + 4 = 8
Correct Answer: B
