/bin - user executable files that are important for OS operations. ls or mv is located in it.

/sbin - location of essential executable files for root user. For example reboot file is located in it.

/etc - location of configuration files. Please note that most of configuration files will be placed in subdirectories associated with their programs.

/lib - shared libraries used by applications that are located in /sbin and /bin directories.

/boot - location of boot related files. For example kernel related files will be located there.

/dev - location of device files.

/proc - virtual directory that contains files related to system operations.

/var - var stands for variable. This the location of files that frequently change. For example log files will be located here.
