The Ambedkar Community Computing Center is not a private or public educational institution, it is a computing education center run by youths from a local group called Ambedkar Sanga that works in the slums of the area.
The Center was founded in 2007 in an effort to bring the world of computers close to underprivileged children and youths who otherwise would have little opportunity to get in contact with this technology.
Amigo is a word picked by few community Center students. This happened after some time the center was started. Probably before one of their events to create a banner.
From Spanish amigo (“friend”), from Latin amicus (“friend”), derived from amare (“to love”). Compare French ami, Italian amico, Portuguese amigo and Romanian amic.
