(1) Hub
The hub is a line concentrator that has a repeater facility for accommodating twisted-pair cables
for 10BASE-T.
The hub is available in various types including the one having a 10BASE2 interface or an
interface for cascading (making connections in cascade). Up to four hubs can be connected in
cascade. You can also use a stackable hub, which consists of a number of hubs but allows you
to handle it as a single hub.
