Linux is a multi-user operating system. Here, the root user holds the ultimate power over the entire system. For security reasons, it’s mandatory to have it password protected. In some cases, the root user is even disabled. Linux has root user enabled by default.
Besides security concerns, access to root privilege is necessary when it’s required to perform system maintenance. The sudo command does exactly that. It grants a command/script root privilege as long as it is executed. Users having access to the sudo command are managed by the sudoers file
