diffrence between topology?

Question

what is the difference between bus topology and star topology?

Answer 1

With a bus topology, all devices are connected to a single backbone. In a star topology, all devices are connected to a single hub.

Answer 2

A bus topology connects nodes in a linear manner. A star topology is like a hub extending to different nodes on a single network forming the shape of a star.

Answer 3

A network topology is the pattern of links connecting pairs of nodes of a network. It's the shape of a LAN or other communications system. A given node has one or more links to others, and the links can appear in a variety of different shapes. The simplest connection is a one-way link between two devices. A second return link can be added for two-way communication. Modern communications cables usually include more than one wire in order to facilitate this, although very simple bus-based networks have two-way communication on a single wire.

A bus network is a network architecture in which a set of clients are connected via a shared communications line, called a bus. There are several common instances of the bus architecture, including one in the motherboard of most computers, and those in some versions of Ethernet networks.

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. If the 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. An active star network has an active central node that usually has the means to prevent echo-related problems.

Answer 4

What is the differences between bus topology and star topology

Answer 5

As others have stated, a bus topology connect all computers to one backbone. It's important to note, that with this topology, there is no redundancy. If one computer in the bus fails, all will experience connectivity problems.

A star redundancy provides more redundancy, but can still provide a single point of failure if the central unit (hub) fails. However, if 1 computer fails, it has no affect on other computers in the network.

Answer 6

has to do with the shape... of the connections a great website that illustrates this http://compnetworking.about.com/od/networkdesign/ig/Computer-Network-Topologies/Star-Network-Topology-Diagram.htm

Answer 7

The only difference between a "crush" and "falling in love" is the level of commitment involved by the person who uses either term. If they call it a "crush" they're thinking the involvement is minor and passing, If they use the term "falling in love," it means that it's more serious and that they're thinking about investing time in the relationship.
