/etc

The /etc directory in a Linux system is where configuration files are stored. These files define how the system and various programs behave. Think of it as a central control panel containing instructions and settings that tell the computer how to operate, manage users, network connections, and system services. These files are mostly plain text, making it possible for administrators to review and modify them to customize or troubleshoot the system. Overall, /etc is essential for configuring the environment and ensuring the system runs smoothly according to user preferences and requirements.
