Network Topologies And The Network

Component needed will be; five 24 port switches, Cat5e UTP and the workstation computers with the proper NIC devices. This layout would start with the 24 port switch in the center of the network. This switch is connected using a Cat5e UTP medium to the other 5 switches. Each switch is connected to the workstation computers using Cat5e UTP medium. This will create a physical star topology. The logical topology will be based on a 100BaseTX and incorporate the use TCP/IP protocol.

“Networks are all around us. They are in our walls, in the air. At schools, hotels, hospitals, even coffee shops. Always there, always on…This power exists today. In our routers. In our switches... . (Cisco, n.d.)

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

A Star topology is the second type of topology represented. This topology is easy to install as well as being easy to expand by connecting additional nodes or devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices need to be added or removed, it does not cause disruptions to the network. This type of topology is used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

In the transport topology, each advanced PC is joined with a primary link alluded to as the transport. Hence, as a result, each computerized PC is specifically associated with each distinctive advanced PC inside of the system.

Simply put, a topology is that the layout of a network. There are extremely 3 basic kinds of topologies. they're Star, Bus, and Ring. Let me justify them to you.

Most business networks today use switches to connect computers, printers and servers within a building or campus. A switch serves as a controller, enabling networked devices to talk to each other efficiently. Routers, on the other hand, are a much more sophisticated piece of technology. They are small like a switch and look like modems in which multiple nodes can be connected. Today’s routers are actually designed for the purpose of connecting multiple ‘area networks’ (both local and wide). In terms of the internet, routers actually serve as a temporary destination for network traffic. Routers are capable of transmitting and receiving data packets but will actually ‘read’ the packet to get its IP address for determining the packet’s destination. Unlike the switch, routers are capable of joining the multiple networks together; in the case of Kudler Fine Foods, their three store locations. “Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.” (FCITC, 1997) There are four basic types of cable: Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP), Coaxial Cable, and Fiber Optic Cable. Unshielded twisted pair can range from basic telephone-grade wiring to high-speed cabling. This cable consist of four pairs of wires inside the outer covering each pair twisted with a different number of twists per inch to reduce/eliminate interference from adjacent pair or other devices. The tighter the twisting the higher data rates it supports but it also will increase the cost of the cable. Shielded twisted pair cables are actually shielded from radio and electrical frequencies and

Local area networks (LAN) are all about sharing information and resources. To enable all the nodes on the SCADA network to share information, they must be connected by some transmission medium. The method of connection is known as the network topology.

The main topologies are Bus (All Workstations are connected to one line), Star (All Workstations are connected to a central hub), Ring (All workstations are connected to fellow workstations left and right of them) and Mesh (All workstations are connected to each other). A lot of topologies are designed to allow more workstations to be added at a later date. But a lot of topologies also have weaknesses, such as the Bus topology and the Ring topology, which would both break down if a node was to fail.

For example, the ring and bus topologies are very inefficient with the way traffic travels throughout the network are difficult to implement on a large scale

Write a short explanation (two to three sentences) of each concept and be prepared to discuss it with the class.

In a bus topology, all segments are associated with and share a solitary wire. Certain media sorts, for example, 10Base5 and 10Base2 Ethernet, utilize a bus topology. Regularly, unique sorts of connectors or handsets are utilized to interface the links to give the bus topology. In 10Base5, for instance, every gadget interfaces with a solitary strand of the coaxial link by means of a vampire tap. This gadget takes advantage of the single strand of the coaxial link and gives the physical association from a systems administration gadget to the single strand of the link. (Deal, 2015)

Deciding what type a network to use a local area network(LANs) device the end-user uses to access the system is the client. The install requires clients, Servers switches, router, and media. The network needs a topology to rapidly placement of all components and devices. For example, you can use the ring topology. Topology ring allows devices on a circle to make turns transmitting the ring connection for media access was out a problem. Security is a big deal so many cyber-attacks companies must be to protect their clientele privacy.

The Linear Bus Topology has all of the nodes connected to on single connection medium which has two end points. This type of set-up has multiple advantages, such as it is easy to set-up, it requires the least amount of cables, low cost, and it is used for small LAN’s. The distributed Bus Topology is a more complicated version of a Bus network. Unlike the Linear Bus, the Distributed Bus has more than two end points. This setup starts out looking like the linear bus with a main trunk cable that is referred to as the root or head end. Multiple network nodes can be connected to this main trunk line. The trunk cable branches off by a connector on the main trunk. This type of Bus topology has more disadvantage than the linear bus topology. The intersecting

First, we need to understand the difference between logical and physical topographical layouts. Logical layouts are how the data move across the network and physical layouts are how the network relates to its wires and hardware (Kevin Wallace, 2012). Note that how the data moves through the network is not going to be the same as how the data is physically structured (Michael Harris, 2008). The most coming physical topologies are Bus, Star, and Star-Wire Ring (Kevin Wallace, 2012). The most coming logical topologies are Bus, Ring, and Star (Kevin Wallace, 2012).
