FAQs on Optimal Page Replacement Algorithm in Operating System Video Lecture - Crash Course for UGC NET Computer science
| 1. What is the optimal page replacement algorithm in operating system? |  |
Ans. The optimal page replacement algorithm, also known as OPT, is an algorithm that replaces the page that will not be used for the longest period of time in the future. It is considered the most efficient page replacement algorithm but is impractical to implement in real operating systems due to the need for future knowledge of page references.
| 2. How does the optimal page replacement algorithm work? | |
Ans. The optimal page replacement algorithm works by replacing the page that will not be referenced for the longest period of time in the future. It requires knowledge of all future page references, which is not feasible in real-world scenarios, making it more of a theoretical concept.
| 3. What are some limitations of the optimal page replacement algorithm? | |
Ans. Some limitations of the optimal page replacement algorithm include the need for future knowledge of page references, which is not realistic in real operating systems. It also requires a significant amount of processing power and memory to keep track of all future page references.
| 4. How does the optimal page replacement algorithm compare to other page replacement algorithms? | |
Ans. The optimal page replacement algorithm is considered the most efficient in terms of page replacement, as it minimizes the number of page faults. However, it is not practical for real-world use due to the need for future knowledge of page references. Other algorithms like FIFO, LRU, and LFU are more commonly used in operating systems.
| 5. Why is the optimal page replacement algorithm not commonly used in real operating systems? | |
Ans. The optimal page replacement algorithm is not commonly used in real operating systems because it requires knowledge of all future page references, which is not feasible. Implementing such an algorithm would require a significant amount of processing power and memory, making it impractical for most operating systems.
