Linux File System Structure
Linux file system has a hierarchal file structure as it contains a root directory and its subdirectories. … The data structure needs to support a hierarchical directory structure; this structure is used to describe the available and used disk space for a particular block.
What are the two types of the files found in the filesystem hierarchy standard?
Filesystem Hierarchy Standard (FHS)
- /boot – contains files related to the initial booting of the computer.
- /bin – contains certain critical executable files, such as ls, cp, and mount.
- /dev – contains device files like hard disks or CD-ROMs.
- /sbin – similar to /bin, but it contains programs that are normally run only by the system administrator.

How does file system work in Linux?
The Linux filesystem unifies all physical hard drives and partitions into a single directory structure. … All other directories and their subdirectories are located under the single Linux root directory. This means that there is only one single directory tree in which to search for files and programs.
Why is Linux file system referred to as hierarchical?
Why is the GNU/Linux filesystem referred to as hierarchical? Answer: … Instead hard drive can by mounted ( connected ) to any directory within an entire file system. On the top of the file system hierarchy structure is a root directory represented by “/” which expands to sub-directories forming hierarchical tree.
What are the four fundamental components of every file system on Linux?
The central concepts are superblock, inode , data block, directory block , and indirection block. The superblock contains information about the filesystem as a whole, such as its size (the exact information here depends on the filesystem). An inode contains all information about a file, except its name.
What are the basics of file system?

…
Directory Structure
- It has a root directory (/) that contains other files and directories.
- Each file or directory is uniquely identified by its name, the directory in which it resides, and a unique identifier, typically called an inode.
What type of file system does Linux use?
The majority of modern Linux distributions default to the ext4 filesystem, just as previous Linux distributions defaulted to ext3, ext2, and—if you go back far enough—ext.
What is a file hierarchy?
(2) A file system that organizes data and program files in a top-to-bottom structure. All modern operating systems use hierarchical file systems, wherein access to the data starts at the top and proceeds downward throughout the levels of the hierarchy. See file system, root directory and path. Windows Hierarchy.
What is top directory?
The root directory, or root folder, is the top-level directory of a file system. The directory structure can be visually represented as an upside-down tree, so the term “root” represents the top level. All other directories within a volume are “branches” or subdirectories of the root directory.
What does usr mean?
/usr ( from English “User System Resources” ) – catalogue/directory in UNIX-like systems, containing dynamically combined programs, user files and manually-installed programs.
Where are user files stored in Linux?
Every user on a Linux system, whether created as an account for a real human being or associated with a particular service or system function, is stored in a file called “/etc/passwd”. The “/etc/passwd” file contains information about the users on the system.
How do directories work in Linux?
When you login to Linux, you’re placed in a special directory known as your home directory. Generally, each user has a distinct home directory, where the user creates personal files. This makes it simple for the user to find files previously created, because they’re kept separate from the files of other users.
What is the top level directory of Linux?
/ : The top level directory in your system. It’s called the root directory, because it’s the root of the system: all the rest of the directory structure emanates from it like branches from the root of a tree. Don’t get confused by the /root directory, by the way; that’s a different ‘root’.
