All juniper species grow berries, but some are considered too bitter to eat. In addition to J. communis, other edible species include Juniperus drupacea, Juniperus phoenicea, Juniperus deppeana, and Juniperus californica.
Secure Network Topologies. The foundation of a LAN is the topology, or network architecture. A topology is the physical and logical layout of a LAN in terms of resources provided, distance between nodes, and transmission medium. Depending upon the needs of the organization that the network services, there are several choices available for network implementation.
In Bus Network Topology a single cable is used to connect all devices on the net. This cable is often referred to as the network Backbone. When communication occurs between nodes the device sending the message broadcasts to all nodes on the network, but only the desired recipient digests the message.ince Logical Network Topology builds upon the underlying Network Physical Topology the set of standard computer physical topologies will reviewed first as background to the performance analysis discussion. This will be followed by a brief description of Graph Theory, and then the network analysis examples.
