Linux /root, what is meant by root user?

I need clarity, what is the difference between root user, user, and system admin?

I'm learning linux and the /root is defined as home directory for the root user. I don't understand what root user exactly means

Root means nothing on the system is protected from you. NEVER EVER run as root as it is too easy for a typo to get you in trouble.

Root is kind of a hold over from UNIX and DOS days. It means you are at the lowest level disk directory. The root - all directories branch out from it.

In Linux is just means you have all admin access. You are at the "root" of the system.

Root IS the administrator account. It is considered POOR form to use the ROOT or administrator account for general purposes. It is wiser to create a new user with privileges...not necessarily ALL privileges, for normal daily use.
