Token Ring
- (February -
2009)
Token Ring is another form of network configuration which
differs from Ethernet in that all messages are transferred in a
unidirectional manner along the ring at all times. Data is
transmitted in tokens, which are passed along the ring and
viewed by each device.
When
a device sees a message addressed to it, that device copies the
message and then marks that message as being read. As the
message makes its way along the ring, it eventually gets back to
the sender who now notes that the message was received by the
intended device. The sender can then remove the message and free
that token for use by others.
Various PC vendors have been proponents of Token Ring networks
at different times and thus these types of networks have been
implemented in many organizations.
