A device for connecting nodes to a LAN (see first write-up). An
Ethernet hub, or
repeater, sends
traffic to all attached stations, which have to
share access. All stations detect a
collision. A
Token Ring hub, on the other hand, passes the
token to each node.
A hub is a relatively cheap way to connect nodes while keeping cabling simple. However, they are still shared-access, so performance will degrade with as the number of nodes becomes larger.
