- The volume control block is used to maintain the system heap, that's why it is wrong.
Answer:
The expression to this question can be defined as follows:
Expression:
(x >= 0 && y<0) //check condition using AND operator
Explanation:
In the given question it is defined that x and y are an integer variable that holds some value, in which it defines a condition that checks the value of variable x is positive, and the value of y is negative.
- To check positive value a condition is used, that checks x greater than equal to 0, and to check negative value, it uses condition, that is y is less than 0.
- In the above condition, the AND operator is used, which executes when both conditions are true.
Answer:
In a buffer
Explanation:
We can define a buffer as a temporary holding area for data between the various devices and the CPU make I/O synchronization especially if there are multiple devices attempting to do I/O at the same time.
Items stored at the buffer helps to reduce the The incompatibilities in speed between the various devices and the CPU.
