В видео рассматриваются принципы хранения файлов в ОС Linux, назначение и содержание индексных дескрипторов (inodes). Как хранится информация о содержимом каталогов в файловых системах, используемых в Линукс (Ext4. XFS, и т.д.) и как организовано хранение самих файлов. Говорим о таблице inodeов и как она ограничивает количество файлов, которое вы можете хранить на файловой системе.

5G Call Flows (Session 1): How a 5G UE performs Initial Access
5G Call Flows (Session 1): How a 5G UE/Mobile performs Initial Access

One of the most complex area for beginners is to understand 5G Call Flows and Signaling procedures. 3GPP defines them but they are not easy to understand. So, in this video, I have explained the 5G Call Flows in a simplified manner and I have also included the contents of some of the important messages to show what actually goes on between UE/Mobile and the 5G network during the 5G Initial Access or Network Entry procedure! Moreover, I have highlighted some of the important 5G KPIs in the end that will help the audience to correlate the 5G Call Flow \u0026 Signaling procedure with the 5G KPI itself. This is also one of a popular 5G Interview topic as well and many questions are asked from this Signaling Procedure.

Understanding Linux and UNIX inodes and file metadata
Do you need a greater understanding of Linux inodes and file metadata?
Here we take a tour to make sure that we do truly understand inodes in Linux and what they do and contain. Firstly they do not contain the file name. This is stored separately and the file name is linked via the inode number to the inode. The inode itself contains the metadata about the file: the mode, ownership, size etc. Keeping the filename separate to the file metadata does mean that we can have then hard links, multiple file names that point to the one file by way of the inode. We will take a look at the ls command with the i option along with stat and find inum ; all of these command line tools help you gain knowledge and use inodes effectively in your system

Q. What is an Inode in Unix?
An Inode is a Data Structure in Unix that denotes a file or a directory on file system. It contains information about file like location of file on the disk, access mode, ownership, file type etc.
Each Inode has a number that is used in the index table. Unix kernel uses Inode number to access the contents of an Inode.
We can use ls i command to get the inode number of a file.
Q. What is the difference between absolute path and relative path in Unix file system?
Absolute path is the complete path of a file or directory from the root directory. In general root directory is represented by / symbol. If we are in a directory and want to know the absolute path, we can use pwd command.
Relative path is the path relative the current location in directory.
E.g. In a directory structure /var/user/kevin/mail if we are in kevin directory then pwd command will give absolute path as /var/user/kevin.
Absolute path of mail folder is /var/user/kevin/mail. For mail folder ./mail is the relative path of mail directory from kevin folder.
