Network Topology Paper Hierarchical Star - When implementing a hierarchical, all computers are connected to a single, centrally located point. This central point is usually a hub of servers and switches located in the main equipment room and interconnected through the main cross- connection. All cabling used in a hierarchical star topology is run from the equipment outlets back to this central location. Bus Topology - The is the simplest network topology. Also known as a , in this topology all

Rosa Mingo 10/ 15/15 Ms. White Alexander Grothendieck One of the foremost mathematicians of 20th century, Alexander Grothendieck is a pioneer of modern algebraic geometry. His contributions to algebraic geometry, homological algebra and functional analysis are so huge and vast, that it antagonized even his most ardent followers who envied him for his achievements. His genius was honored by ‘Fields medal’ and the Crawford prize though he refused both on ethical grounds. During his long career

The Hierarchical Star Topology consists of all the computers in a specific network being connected to a single main point, like a server or hub, which in turn, would be located in an equipment room or centralize location. With the Star topology, hubs are used to facilitate the topology. The drawback to this is, there is about a 20%- 30% waste in unused ports and a company is paying for more ports that is can or will use. Another drawback to this topology is the entire network is reliant on the

Case: You are appointed as a technical expert to implement a network system for a small size maritime supplyrepresentative company with four users. The company provides supply services to Maritime shipping companies through a worldwide network of suppliers. Its owner is a maritime business expert who doesnot know much about the use of computer systems to support her business. Therefore, she has decidedto employ you as a consultant on a short term basis to set-up appropriate systems in a network

node maintains one or more routing tables which represents the entire topology of the network. These tables are updated regularly so that when a route is needed, these tables will be checked to find out whether the routing information is already available or not. If any node already knows the path for sending information, then the latency will be low. However, when the nodes are mobile then the cost of maintaining all topology information will be very high. REACTIVE ROUTING (ON-DEMAND) PROTOCOLS:

Mesh Topology A mesh network is a local area network that employs one of two connection arrangements. There are two type of Mesh topology; full mesh topology or partial mesh topology. In the full mesh topology, each workstation or other device is connected directly to one another. In the partial mesh topology, some nodes are connected to all the others, but some of the nodes are connected only to those other nodes with which they exchange the most data. A mesh network is reliable and offers redundancy

Networking Networking There are many different types of topologies and this paper will discuss many advantages and disadvantages of them. Bus Topology In a bus topology, all the network devices are in a linear shape which acts as a common backbone. There is a single cable which functions as the go between for the devices that are attached to this connector. The device will send the messages to all of the devices attached to this shared cable. However, only the intended device will receive and

fixed. 1.2 ZigBee Topologies The three ZigBee network device types are end device, router and coordinator. ZigBee support three kinds of topologies. These are star, tree and mesh. In all topologies the ZigBee network must contain one coordinator. The coordinator is responsible for allowing other devices to join the network, selecting transmission channels and for starting the ZigBee network. The coordinator can also route traffic and it’s the root node in tree and star topologies. ZigBee network supports
