What is Root Access?
Root is the user name, or account, that by default has privileged access to all commands and files located on the operating systems such as Linux or any other UNIX like operating system. The term Root is derived from a tree root, since it reflects the starting point in the hierarchical arrangement. The root node of a file system is also known as the root directory. In addition to this, Root is the name of a user who has administrative access on a UNIX or LINUX server. It can also be known as the root account, root user and the superuser.
Root privileges are the powers given to an authorized user. This account is the most privileged account on the system that possesses absolute power like the ability to read, access, modify and execute specific files and directories, and revoke access permissions for other users.
