Which directory is commonly used to store configuration files on Unix-like systems?

• A. /etc
• B. /bin
• C. /usr
• D. /sbin

Answer: (A)

Configuration files that control system behavior and service settings are traditionally stored in a dedicated location that is reserved for global, system-wide settings. On Unix-like systems, that place is /etc. You’ll see files and subdirectories there for essential services and system configuration, such as /etc/hosts for host mappings, /etc/passwd for user accounts, and service-specific configs like /etc/ssh/sshd_config or /etc/nginx/nginx.conf. These files are usually owned by root and protected to prevent unintended changes, since altering them can affect how the entire system operates. It’s helpful to contrast with other standard directories: /bin and /sbin contain executable programs needed for basic operation and system administration, not configuration data. /usr holds user-space programs and libraries, including many applications, rather than system-wide settings. While per-user preferences often live in a user’s home directory (for example, hidden files or ~/.config), the central repository for global configuration remains /etc.
