The Universal Internet Lab (UIL) recently developed an ingenious new method of connecting its computers. Each computer is directly connected to some other set of computers such that there is exactly one sequence of connections between any pair of computers. Stated differently, by treating the computers as vertices and connections as edges, the computers and their connections form a tree.
While this may seem constraining, connecting computers in this manner has some benefits. For example, software updates can now be installed in a distributed manner. Instead of each computer connecting to some central server to download a software update, only one computer needs to be updated. Then, by using these connections between computers, one computer can update all the other computers directly or indirectly!
