	Network topology - Wikipedia, the free encyclopedia
		Network topology is determined only by the configuration of connections between nodes; it is therefore a part of graph theory.
		As in the conventional star network, individual nodes may thus still be isolated from the network by a single-point failure of a transmission path to the node.
		A Star ring network consists of two or more star topologies connected using a multistation access unit (MAU) as a centralized hub.

	Star network - Wikipedia, the free encyclopedia
		Star networks are one of the most common computer network topologies.
		In its simplest form, a star network consists of one central switch, hub or computer which acts as a router to transmit messages.
		An active star network has an active central node that usually has the means to prevent echo-related problems.

	Novell's Networking Primer
		In even a simple physical star topology, the actual layout of the transmission media need not form a recognizable star pattern; the only required physical characteristic is that each network device be connected by its own cable to the central connection point.
		The distributed star topology, illustrated in Figure 13, is a more complex form of the physical star topology, with multiple central connection points connected to form a string of stars.
		However, the star topology and its derivatives are also susceptible to bottlenecking and single-point failure; the latter is often remedied by providing a redundant backup of the hub node.

	Definition: network topology
		star topology: A network topology in which peripheral nodes are connected to a central node, which rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, including the originating node.
		Note 3: If the star central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time, i.e., to and from the central node, plus any delay generated in the central node.
		Note 2: As in the conventional star network, individual nodes may thus still be isolated from the network by a single-point failure of a transmission path to the node.

	Phone-man's Home Phone Wiring Advice Page - Routing of Your Phone Cable
		In a ring topology, all jacks are on one cable that forms a "loop", routed through the house from one jack to the next, with both "ends" connected at the NID.
		In a bus topology, all jacks are on one cable that starts at the NID and is routed through the house from one jack to the next and terminates at the last desired jack location.
		For a star topology, the best option is to mount a "66-block" or "110-block" and terminate each cable on it separately.

	Lesson 3: Network Topology
		The bus topology is often referred to as a "linear bus" because the computers are connected in a straight line.
		Linear-bus trunks connect the hubs in a star bus, while the hubs in a star ring are connected in a star pattern by the main hub.
		To determine which type of topology would be most appropriate for your site, add up the number of bus selections with check marks next to them, the number of star-bus selections with check marks next to them, and the number of star-ring selections with check marks next to them.

	Security Electronics Magazine - Nuts and Bolts
		Topology defines the physical (wired or wireless) connections of a network but you need to be careful with this definition because physical topology and logical topology (that’s the physical wiring and the data path) are not the same beast at all.
		An attractive aspect of star topology is that you can pull a drop cable from a hub with no impact on the rest of the network – you can also daisy chain hubs to increase input numbers if there comes a point when the star needs to grow.
		What happens with ring topology is that signals are passed around the ring in a big circle with each node on the network examining the signal and passing it on if that signal is not addressed to them.

	Topology (Site not responding. Last check: 2007-10-31)
		A bus topology, more completely called a Common Bus Multi-point Topology, is a network where, basically, one single network cable is used from one end of the network to the other, with all the different network devices, computers etc (called nodes) connected to the cable at different lo-cations.
		A star topology is one in which a central unit, called a hub or concentrator, hosts a set of network cables that radiate out to each node on the network.
		With a star topology, if any single network connection fails (that is, if the connection is cut or damaged in some way), the problem affects only that one connection.

	What is topology? - A Word Definition From the Webopedia Computer Dictionary
		ring topology : All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it.
		star topology: All devices are connected to a central hub.
		Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub.

		In a real-life implementation of even a simple physical star topology, the actual layout of the transmission media need not form a recognizable star pattern; the only required physical characteristic is that each network device be connected by its own cable to the central connection point.
		Media access control for the logical ring topology is almost always based on a form of token passing, the basics of which are described in the logical bus topology section.
		In the logical star topology, network switches are used to restrict transmissions to a specific part of the transmission media (transmission path restriction is the identifying characteristic of a logical star).

	STAR TOPOLOGY
		A star network uses a central server to route data between clients.
		One of the advantages of a star network is that, a low specification twisted-pair cable can be used for connection between the server and the nodes (clients) since data rate is relatively low between the central server and the nodes.
		The basic problem with the star topology is that the network is highly dependent upon the operation of the central server.
