Sudo

sudo is a program for Unix-like computer operating systems that allows users to run programs with the security privileges of another user, by default the superuser.

Wheel (computing)

In computing, the term wheel refers to a user account with a wheel bit, a system setting that provides additional special system privileges that empower a user to execute restricted commands that ordinary user accounts cannot access.
