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.
