Allows 10/100 Mbps or 10/100/1000 Mbps Ethernet ports to establish for the
following features:
• Duplex/ Half Duplex Mode.
• Flow Control.
• Speed.
A mechanism used with Half Duplex mode that enables a port not to receive a
message.
The main segment of a network. Backbone types include:
• Building.
• Campus.
• Metropolitan.
• National Data.
• Telecommunications.
The main BUS that carries information in the device.
Specifies the amount of data that can be transmitted in a fixed amount of time. For
digital devices, bandwidth is defined in Bits per Second (bps) or Bytes per Second.
Indicates the amount of bandwidth assigned to a specific application, user, and/or
interface.
Indicates the number of signaling elements transmitted each second.
Indicates that traffic is assigned to the lowest priority queue, and packet delivery is
not guaranteed.
Border Gateway Protocol. Enables information sharing, routing information
between groups of routers.
Indicates the boot version.
Bootstrap Protocol. Enables a workstation to discover its IP address, an IP address
of a BootP server on a network, or a configuration file loaded into the boot of a
device.
Bridge Protocol Data Unit. Provides bridging information in a message format.
BPDUs are sent across switch information with in Spanning Tree configuration.
BPDU packets contain information on ports, addresses, priorities, and forwarding
costs.
A device that connects two networks. Bridges are hardware-specific, however they
are protocol-independent. Bridges operate at Layer 1 and Layer 2 levels.
