Design+specifications

=HUB= There should be ONE HUB connected to multiple computers (three or more).

Each computer connected to HUB by a cable.

One computer transmits a data package to the HUB

The HUB re-transmits the data package to all connected computers (including the originating computer).

If the data package is destined for a specific computer it is "retrieved' and 'stored/used' by that computer.

All other computers 'discard' their data packet.
