Question

Simulation program for page-replacement algorithms.

Design a simulation program to demonstrate the following page-replacement algorithms/policies:

FIFO (First In, First Out)
OPT (Optimal)
LRU (Least Recently Used)
What command line options should be used for specifying the policy and reference string?

a) -p fifo -l reference_string
b) -p opt -l reference_string
c) -p lru -l reference_string
d) All of the above

Answer 1

The correct command line options to specify page-replacement policies and reference strings in a simulation program are -p followed by the policy name and -l followed by the reference string, applicable for FIFO, OPT, and LRU algorithms.

Step-by-step explanation:

The correct command line options for specifying the policy and reference string are -p fifo -l reference_string, -p opt -l reference_string, and -p lru -l reference_string. Hence, the answer is d) All of the above.When designing a simulation program to demonstrate page-replacement algorithms like FIFO, OPT, and LRU, command line arguments are essential for specifying the policy and the test reference string. The '-p' option typically stands for the policy, and the '-l' option is used to pass the reference string which the algorithm will process, making these commands a standard way to interact with such a program.The correct answer is d) All of the above.

The command line options for specifying the policy and reference string for the simulation program for the page-replacement algorithms are:-p fifo -l reference_string-p opt -l reference_string-p lru -l reference_stringThese options allow you to choose the policy (FIFO, OPT, or LRU) and specify the reference string for the simulation.
