...Assignment 1. Network Topology Paper Hierarchical layout defines how the network topology is structured physically and logically. In physical topology all devices and components are placed in various locations depending on the layout. Logical topology is the flow of data throughout the layout. There are many variations of network topologies that can be implemented. The most common network topologies are star, bus, and ring. Star topology is setup with each host connected to a central hub with a point to point connection. All workstation and other devices are connected to the central hub or switch. That switch is the server and all devices connected to it are clients. All resources must be connected to a central device in order for it to be a star topology. Data that travels in the network passes through the central hub and causes it to act as a signal repeater. The advantages of a star topology are that it is easy to design and versatile in planting additional nodes. The major disadvantage of the star topology is that the hub becomes the single point of failure. Bus topology utilizes a single bus cable to connect each computer and the data from the source travels in both directions to all devices on the bus cable until it finds the specific client. Data is only accepted if the addresses matched up and if it doesn’t match, it’s simply ignored. The last computer connected to the bus needs to be terminated to prevent echoes in the network. Having a single line for bus topology makes...

...Network Topology Paper Assignment 1 Unit 3 Mr. Swailes The study of Network Topology recognizes 8 basic topologies * Point to point * Star * Bus * Mesh * Tree * Hybrid * Daisy chain * Ring Point to point- The simplest topology is the permanent link between two end points Star-in a local area network with a star topology. Each network host is connected to a central hub with a point-to-point connection to a central node called a hub or switch. Bus- In local area networks where Bus Topology is used, each computer is connected to a single Bus cable. A signal from the source travels in both directions to all machines connected on the Bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores it. However, if the data matches it is accepted. The bad part of this topology is that it has a single point of failure which is the cable and if this happens the whole network can shut down. Mesh-is a fully connected network in which each node is connected to each other. A fully connected network does not need to use switching or broadcasting. However its major disadvantage is that the number of connections grows with the number of nodes. It is extremely impractical for large networks. A two node network is technically a fully connected network. Tree-is a combination of a Bus and Star topology. It is arranged to look like a tree. The advantages are it is scalable...

Noida UP, INDIA Mysteriousrao@gmail.comApril 14, 2015 | Abstract In recent days for computing, distributed computer systems have become very important and popular issue. It delivers high end performance at a low cost. Computers are connected by means of a communication network in a distributed computing environment which is arranged in a geometrical shape called network topology. In the present paper a detailed study and analysis on network topologies is presented. Definitions of Physical and Logical Topologies are also provided. Introduction Network Topology is the study of the arrangement or mapping of the elements (links, nodes, etc.) of a network interconnection between the nodes. Topologies can be physical or logical. Physical Topology means the physical design of a network including the devices, location and cable installation. Logical Topology refers to the fact that how data actually transfers in a network as opposed to its design. Some of the most common network topologies are: Physical Topology Physical Network Topology emphasizes the hardware associated with the system including workstations, remote terminals, servers, and the associated wiring between assets. Physical topology defines how the systems are physically connected. It means the arrangement of devices on a computer network through the actual cables that...

...Network Mechanisms This paper will define and describe the differences in mechanisms that make up a network system. It will include topologies and connection mediums, as well as the advantages and disadvantages associated with these network mechanisms. Topologies and connection mediums that will be addressed are the following: Topologies: • Mesh • Bus • Ring • Star Connection Mediums: • Ethernet • Token Ring • FIDDI • Wireless Mesh Topology A mesh topology consists of two types, full mesh and partial mesh. Full mesh topology interconnects all systems to each other. This allows for redundancy if one connection is severed. With partial mesh topology only some workstations are interconnected to other computer systems while; others are only connected with systems that an exchange of data occurs (Mitchell, 2011). The advantages and disadvantages of a mesh topology are: Advantages: Disadvantages: Provides redundant paths between systems Time and material to implement The network can be expanded without disruption to current users. Cost to implement (many connections) Dedicated links for transmitting data Complicated implementation Bus Topology A bus topology uses a common backbone that directly connects each system. The backbone consists of a single cable that all transmissions are sent across by the systems that are attached (Mitchell, 2011). The advantages and disadvantages of a bus topology are: Advantages: Disadvantages: Easy to implement...

...AERONAUTICAL MOBILE AD HOC NETWORKS CONTENTS 1: Introduction 2: Literature Survey 3: References PROBLEM STATEMENT 1.1 Ad-hoc network "Ad Hoc" is actually a Latin phrase that means "for this purpose." It is often used to describe solutions that are developed on-the-fly for a specific purpose. In computer networking, an ad hoc network refers to a network connection established for a single session and does not require a router or a wireless base station. An ad hoc network is a temporary network connection created for a specific purpose (such as transferring data from one computer to another) 1.2 Mobile ad hoc network(MANET) A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the node themselves, i.e., routing functionality will be incorporated into mobile nodes. In other words, MANET is a type of ad hoc network that can change locations and configure itself on the fly. Because MANETS are mobile, they use wireless connections to connect to various networks. This can be a standard Wi-Fi connection, or another medium, such as a cellular or satellite transmission.

... Old-Tech Corporation has 10 computers in its main office area, which is networked in a star topology using 10 Mbps Ethernet hubs, and wants to add five computers in the manufacturing area. One problem with the existing network is data throughput. Large files are transferred across the network regularly, and the transfers take quite a while. In addition, when two or more computers are transferring large files, the network becomes unbearably slow for users. Adding the manufacturing computers will only make this problem worse and result in another problem. Because the ceiling is more than 30 feet high, there’ s no easy way to run cables to computers, and providing a secure pathway for cables is next to impossible. Devise a solution to this company’ s networking problems. As part of your solution, answer the following questions: ● What changes in equipment are required to bring this company’ s network up to date to solve the shared-bandwidth problem? Removing the bridges from each computer removing the Bus topology and removing some of the cable usage with a extended star topology; that way everyone has shared files and their protected with supervision of the administrator. May need to upgrade cable however (details of size unknown). ● What topology and which type of device can be used in the manufacturing area to solve the cabling difficulties? An extended start topology would be the best choice in my opinion because they will have less cables running through because...

By using a systems development plan, The Bead Bar will be able to reach more customers. The Bead Bar should use an Enterprise DBMS to The Bead Bar. The enterprise DBMS will allow The Bead Bar is a large enough company that an enterprise DBMS will be what they need. Enterprise DBMS's are perfect for organizations, and companies that have multiple locations. The enterprise DBMS can give prices, changes, and inventory information to the different locations. Enterprise DBMS runs from one central location, then branches out to the other locations. They can connect directly to the company's websites to give the information needed to run the business such as item prices and inventory levels. The Network Model or the Codasyl is the best model for The Bead Bar. The Network Model allows data entered to be linked to each other. There are no restrictions in how the data is connected to each other as in the Hierarchical Model. This model is very complicated, but is very flexible. The Bead Bar needs flexibility in their data entries. There are many benefits of using a DBMS. One benefit of using a DBMS is that the DBMS transforms the data in a way that takes up less space.

...Institute Network Topology Tom McKellips NT 1310 Aaron Bright October 10, 2013 Network Topology The following paper is going to discuss the three different types of network topologies, hierarchical star, bus, and ring. Each one of these topologies has different uses in the way we set up networks. For each type of topology there are going to be strong points as well as some weak points. The first one to be discussed is going to be hierarchical star. A hierarchical star is a network that has a central point such as an equipment room where all computers, routers, printers, and other devices are connected to. This type of network is mainly used to install a network throughout a large building or school. A star network is the easiest to install and the most universal, but if something happens to the central point than the whole network goes down. The next paragraph will discuss the bus type of network topology. A bus is a network that all devices are connected to a contiguous cable known as a backbone. A bus is used to link multiple star networks together, for example, a building with more than one floor each equipment room is connected by a single backbone to link the networks together. The bus has to have a terminator (usually a resistor) on both ends to keep the signal from bouncing back and forth. If the contiguous cable gets damaged than the whole bus network goes down. The last type of network topology to discuss is the ring. A ring topology requires that...

...There are many different choices that one can make when designing an IT network. These most preferable choices can change depending on your needs, the capabilities that your equipment requires, and perhaps most important, the budget you have available to spend on the network. First, you will have to choose from the various topologies that exist. Second, you will have to determine what type of cable you will use to run your network. Finally you will have to decide if you want to have wireless capabilities. In this paper, you will find a great deal of information that should help you in making your decisions, at the very least, a little easier. Topologies There are several different topologies available to choose from, each with its own traits and flaws. The most common are the bus, ring, and star topologies. There are several other examples, but these are the network topologies that will be covered in this paper. The bus topology is the simplest network topology. also known as a linear bus, in this topology all computers are connected to a single unbroken cable. On a linear bus, each computer determines when the network is not busy and transmits its data as needed. The signal in a bus topology travels down the entire length of the cable, giving its data to each connected device. At the end of the bus is a component called a terminator. The terminator is essentially a resistor that terminates the transmitted data, preventing it from returning back down the bus, which...

...Unit 3. Assignment 1. 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 computers are connected to a contiguous cable or a cable joined together to make it contiguous. The signal in a bus topology travels to both ends of the cable. To keep the signal from bouncing back and forth along the cable, both ends of the cable in a bus topology must be terminated. A component called a , essentially nothing more than a resistor, is placed on both ends of the copper ( coax) cable. The terminator absorbs the signal and keeps it from ringing, which is also known as overshoot or resonance; this is referred to as. If either terminator is removed or if the cable is cut anywhere along its length, all computers on the bus will fail to communicate. Ring Topology - A requires that all computers be connected in a contiguous circle. The ring has no ends or hub. Each computer in the ring receives signals ( data) from its neighbor, repeats the signal, and passes it along to the next node in the ring. Because the signal has to pass through each computer...
