As a novice user of Linux, the types of Linux file systems are confusing. That’s why I need this kind of video that explains it clearly. Linux file systems consist of ext2, ext3, ext4, etc. Each of them has its characteristics.

Demo: Viewing Hardware Information
The Linux Man show us a demo on how to view our hardware information in proc and sys directories. Like the other video, the explanations are clear and easy to understand.
-
The system maintains a free space list that tracks all free disk blocks. It can be implemented mainly as a bitmap, linked list, grouping, and counting. For more details, please read the article.
