Linux Allows multiple users and Multitasking with powerful shell and multiple flavors. Everything in Linux is a file or a Folder
Files are stored in the Directory, even hardware programs are stored in a directory / - Root directory =Where Linux Starts Each folder inside the root has some functionality
/bin - All the commands of Linux is present in the bin folder bin is a shell command that contains all the code related to commands, as the command is written, that file inside bin is executed
/sbin - System Binaries Contains bin executables, but Linux cmds are generally used by system administrators
/dev - device files contain hardware files
