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.
Network topology is the geometric arrangement of nodes and cable links in a LAN. Two general configurations are used, bus and star. These two topologies define how nodes are connected to one another in a communication network. A node is an active device connected to the network, such as a computer or a printer. A node can also be a piece of networking equipment such as a hub, switch or a router.
