Final answer:
The correct content of the Need matrix in Resource Allocation for Operating Systems is (c) Max - Allocation, which calculates the remaining resources that each process requires to complete its execution.
Step-by-step explanation:
The question addresses the topic of Resource Allocation in the context of Operating Systems, which is part of Mathematics related to Computer Science. Specifically, it involves the calculation of the Need matrix in the Banker's Algorithm, which is used in Deadlock Prevention strategies within Operating Systems. The Need matrix is determined by calculating the difference between the Max and Allocation matrices to reflect the remaining resource needs of each process. Therefore, the correct answer is:
To elaborate, if we have a process P that can request a total of X units of a certain resource (indicated in the Max matrix), and P has already been allocated Y units of that resource (as shown in the Allocation matrix), the remaining need of process P for that resource will be X - Y units. This is represented in the Need matrix for each process and resource type.
