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, secondary nodes allow more devices to be connected to a central node, point-to-point connection of devices is another benefit. Having different levels of a network makes it more manageable, hence easier to identify fault identification and isolation. Disadvantages are maintenance of the network may be an issue when the network spans a great area and since it is a variation of a bus…...

...“A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu, 2013). There are several common instances of the bus architecture, including one in the motherboard of most computers. Bus networks may be the simplest way to connect multiple clients even though many may have problems. When two clients want to transmit at the same time on the same bus, this may cause some problems. Thus systems use bus networks normally some may have scheme for collision handling or collision avoidance for communication on the bus. Though this may be quite often in using Carrier Sense Multiple Access or the presence of a bus master’s who controls access to the shared bus resource. “A ring network is a network topology in which each node connects exactly to two other nodes, forming a single continual pathway for each node - a ring” (Conjecture Corporation, 2003). In a ring network data travels from each node to the other node/s with each node handling every packet. A ring network provides only a pathway between any two nodes at one time. Ring networks may be disrupted by the failure of a link. A node failure or cable break will isolate every node attached to the ring. A malfunctioning that any workstation can create problems for the entire network. “A hierarchical network or a tree network resembles a star network in that several computers are connected to a central host computer usually a mainframe” (Miss). “However,......

...STAR TOPOLOGY: 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 act as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star. 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 (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. BUS TOPOLOGY: Bus networks are the simplest as well as the easiest way to connect multiple clients, but may have problems when two clients want to transmit at the same time on the same bus. Thus systems which use bus network architectures normally have some scheme of collision handling or collision avoidance for communication on the bus, quite often using Carrier Sense Multiple Access or the presence of a bus master which controls access to the shared bus resource.

...Unit 3. 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......

...Week 3 Assignment.Network Topology Paper Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network.[1][2] Essentially, it is the topological[3] structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, and/or signal types may differ between two networks, yet their topologies may be identical. A good example is a local area network (LAN): Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric shape that can be used to describe the physical topology of the network. Conversely, mapping the data flow between the components determines the logical topology of the network.

These three parts (Identification, Authentication and Authorization) will not be all for the Remote Access Control Policy, I will need to include the appropriate access controls for systems, applications and data access. I will also need to include my justification for using the selected access controls for systems, applications and data access. The first part I need to implement for this Remote Access Control Policy is Identification, which is defined in this sense as: physical keys or cards, smart cards, and other physical devices that might be used to gain access to something. What needs to be done for the Remote Access Control Policy is a group member policy needs to be setup which uniquely identifies each user. Users should be identified by rank with higher ranking users requiring more authentications. Each individual user should be assigned to a group based on rank with special permissions. Using this system for Identification will make our company more secure in day to day operations. The second part I need to implement for this remote access control policy is Authentication, which is defined as: what you know or passwords, numeric keys, PIN numbers, secret questions and answers.

...Craig Roxbury Unit 3 Assignment 1 Erica Lanier Video Summary 1 In video 1.07 the lesson is on ports and connectors. There are three different types of ports, those are serial port, parallel port and game port. The serial port is usually male and have 9 or 25 pins. The parallel port is usually female and has 25 pins. The game ports are female and have 15 pins. All of those ports have been replaced by USB ports. The video also discusses how the modem connects to a phone line and converts digital to analog. It explains there are two types of SCSI narrow and wide SCSI, the narrow SCSI has 50 pins and the wide has 68 pins. Video 1.09 teaches that there are two types of monitors, you have CRT and LCD. CRT stands for cathode ray tube and LCD stands for liquid crystal display. The CRT is similar to an old television and the LCD uses thin film transistors and the back lighting is through polarized panels. Your specifications of a monitor include screen size, contrast ratio, refresh rate, response time, interfacing, dot pitchand pixel pitch. Video 1.11 focuses on types of printers and the types of problems that come with each. There is the Dot Matrix, Ink Jet and the laser printers.

...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 hub. If it were to fail, the entire network becomes inoperable. In addition to that, there is also potentially a problem if one of the workstations goes down. It can cause interference in the Star topology and cause the entire network to fail. The Star topology, in its basic design, doesn't account for redundancy or diversity, which can make this design very dangerous for business applications. Some of the advantages of the Star topology is it gives a much better signal because all the information isn't shared to every device. You can also add and subtract new devices to the network by simply plugging into or unplugging a device from the hub and monitoring the network is simplified because everything is centralized. The Bus Topology is the simplest network topology. Ethernet is an common example of Bus topology. Once a main network line is laid, all peripherals on the network talk on the same line and listen for each other's communication. One drawback to this topology is at each......
