The way the Linux file system is laid out makes perfect sense. I've been using Linux for so many years that I can't imagine another file system making more sense.
Root (aka '/') is where all other directories are found. The root directory is the parent of all directories on the system.
Home is the directory that houses all user directories. For example, you might have /home/olivia, where all of user olivia's files and configurations live.
Standard users do not have full access to most directories under root. The only directory users have full rights to is their home directory.
