outer ring
Edge of circle
The outer ring is the peripheral zone of a circular or layered structure, farthest from the center.
In cities, the outer ring typically refers to suburban areas or bypass highways encircling the urban core: Traffic on the outer ring was backed up for miles.
In organizations or social networks, the outer ring contains those with the least access or influence—peripheral members rather than insiders: He was part of the outer ring, never privy to the real decisions.
