What is directory hierarchy in CentOS Linux?

When it comes to using the CentOS operating system, having a clear understanding of the file organization is crucial for efficient navigation and management of the system. The way files and directories are structured in CentOS follows a hierarchical system, which allows for better organization and ease of access to different components of the operating system.

At the top of the hierarchy lies the root directory, often represented by the symbol "/", which serves as the starting point for all file paths in the system. From the root directory, the file system branches out into various directories, each serving a specific purpose. These directories are like containers, organizing various files and subdirectories in a logical and systematic manner.

One important directory in CentOS is the "bin" directory. It contains essential executable binary files that are required for basic command execution. Commands such as "ls" for listing files and "mkdir" for creating directories are located in the bin directory. This directory is vital for any user or administrator as it houses the fundamental system commands necessary for day-to-day operations.

Another significant directory in the CentOS file hierarchy is the "etc" directory. This directory contains system configuration files that are vital for the proper functioning of various software and services in the operating system. Configuration files for network settings, user accounts, and system-wide preferences can be found within the etc directory. Understanding and modifying these configuration files can deeply impact the overall behavior of the CentOS operating system.
