EASY-HOW-TO Page Replacement Algorithm (FIFO, Optimal, and LRU) Tutorial (Manual)

In this video tutorial, you will learn how to:
1. Apply First-In-First-Out (FIFO), Optimal, and Least Recently Used (LRU) Page Replacement Algorithms in a given reference string and the number of page frames to be used to show the page frame contents every time there occurs a page fault.
2. Derive the total number of page faults per page replacement algorithm.
3. Apply the shortcut method for FIFO, Optimal, and LRU Page Replacement Algorithm to derive the number of page faults faster.
4. Choose the best page replacement algorithm to be used in a given reference string and the number of page frames context.

Thank you so much, you went into more detail than my professor and I understand FIFO completely now. :)

You're very welcome! 🥰 Of course, this is a technical concept in Operating Systems. It is a must that we must explain the concept in the simplest way possible so that our students can understand. God Bless!

You're welcome! I am hoping that my content helped you. 😊

[@AzureeTech]

You've really explained it so well, books are bit confusing. Thank You☺

[@BlancaflorArada]

You're very welcome! 🥰 I am really flattered that my content is better than published books made by seasoned professors in Computer Science/IT. God Bless!

Thank You maam for an amazing presentation and clear explanation of this. Really saves my day.

[@BlancaflorArada]

You're most welcome! 😊 It really fills my heart that you understood the page replacement algorithms because of my material.

Great explanation and also nice hand writing

[@BlancaflorArada]

Thanks a lot 😊

best explaination thanks.

[@BlancaflorArada]

You're very welcome! 🥰 I am really glad to hear that it helped you understand the Page Replacement Algorithms. God Bless!

You're very welcome! 🥰 I hope that you learned something from this lecture. God Bless!

[@fadabbeyy4865]

you re the best👍👍👍👍👍👍👍👍👍

[@BlancaflorArada]

Thank you very much!

[@ambernicoleforbes79]

Thank you for this great explanation! Optimal equals the least amount of page faults but can you help me understand a scenario where it can be feasibly implemented?

[@BlancaflorArada]

You're very welcome! 🥰 I am really glad to hear that it helped you understand the Page Replacement Algorithms. God Bless!
For your question, please let me get back and update you about this.

[@nashatalimohammadalrefaipc7923]

why did you choose 3 frames ??? can I choose another number of frames?

[@BlancaflorArada]

Yes, you can any number of frames.
