Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are

TIME POWER SYSTEM SECURITY ASSESSMENT USING ARTIFICIAL NEURAL NETWORKS REAL TIME POWER SYSTEM SECURITY ASSESSMENT USING ARTIFICIAL NEURAL NETWORKS Abstract Contingency analysis of a power system is a major activity in power system planning and operation. In general an outage of one transmission line or transformer may lead to over loads in other branches and/or sudden system voltage rise or drop. The traditional approach of security analysis known as exhaustive security analysis involving

Problems with Formal Networks Formal networks are defined‚ setup and maintained by the organization. They are put into place to make sure information‚ resources‚ problems and punishments are used efficiently and not abused. When these networks are used properly everything will flow up and down the chain of command smoothly. This chain of command comes from the basic principle of a formal network; assigning titles to employees and to give them a certain amount of responsibility to go along with

Design of a Network When a network is being designed‚ the architect must first think about the logical layout and that should be enforced. When he figures out what devices need to communicate and how‚ a physical design of the network can be implemented. A logical design is the reasoning of a network‚ with no particular devices or locations chosen. The physical design of the network is when the devices are picked and their actual location determined. When the logical design of a network is planned
