Question

Central node dependency problem arises in networks with ________ topology a)star topology b)mesh topology c)bus topology d)ring topology​

Answer 1

Your Answer:

Star topology

Star topology is an arrangement of the network in which every node is connected to the central hub, switch or a central computer.

Explanation:

− Central node dependency, if central hub fails, the whole network fails to operate. − Many star networks require a device at the central point to rebroadcast or switch the network traffic. Devices are connected with many redundant interconnections between network nodes.

Answer 2

Answer:

The correct answer is a) Star toplogy

Explanation:

Network topology is the arrangement of the factors (hyperlinks, nodes, and so forth.) of a communication community. Community topology may be used to define or describe the arrangement of various sorts of telecommunication networks, such as command and manipulate radio networks, business fieldbusses and computer networks.

Network topology is the topological structure of a community and can be depicted bodily or logically. it is an application of graph concept wherein communicating devices are modeled as nodes and the connections among the gadgets are modeled as links or strains among the nodes. bodily topology is the placement of the diverse additives of a community (e.g., tool region and cable installation), at the same time as logical topology illustrates how statistics flows inside a network. Distances among nodes, bodily interconnections, transmission rates, or sign kinds may additionally range among  one-of-a-kind networks, yet their logical topologies may be equal. A community’s bodily topology is a selected problem of the bodily layer of the OSI model.

Examples of network topologies are found in nearby region networks (LAN), a commonplace pc network set up. Any given node in the LAN has one or extra bodily hyperlinks to different devices within the community; graphically mapping these hyperlinks results in a geometrical form that can be used to explain the bodily topology of the community. A extensive type of physical topologies were used in LANs, including ring, bus, mesh and big name. Conversely, mapping the statistics waft among the additives determines the logical topology of the community. In assessment, Controller place Networks, common in motors, are often allotted manipulate machine networks of 1 or more controllers interconnected with sensors and actuators over, invariably, a physical bus topology.
