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.
Star topology networks generally have a hub in the center of the network that connects all of the devices together using cabling. When bits hit a networking device, be they hubs, switches, or routers, the devices will strengthen the signal and then send it on its way. A hub is simple a multiport repeater. There is usually no software to load, and no configuration required (i.e. network administrators donât have to tell the device what to do).
