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.
A star topology is a LAN architecture in which the endpoints on a network are connected to a common central hub, or switch, by dedicated links. Logical bus and ring topologies are often implemented physically in a star topology, which is illustrated in the following figure.
