Network Topologies Network topologies are an important part of the network. Without the proper topology, the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations, or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed. In a mesh topology, the devices are connected with many redundant interconnections between nodes. Each device in the mesh topology is connected to every other device in the network. The mesh topology is the most expensive to implement but is …show more content…
Data is transferred quickly without congestion. All computers have the same amount of access to the rest of the network. Disadvantages to the ring topology are, failure of the network if one computer fails, isolating problems with the network is difficult, and the addition or subtraction of computers to or from the network causes disruption in the network. Star Topology The star topology consists of one central switch, hub, or router to transmit messages. The computer will send a signal to the hub, which receives and then retransmits the message to all the other computers or devices attached to the hub. Good performance is an advantage to using the star topology. Centralization of resources, ease of set up and expansion, and the network still performs properly when one computer fails are all advantages to the star topology. The expense of installation, extra hardware required, and if the central hub fails the entire system fails, are disadvantages to the star topology. Ethernet Ethernet is a network technology for local area networks (LAN). "Ethernet uses a bus or star topology and supports data transfer rates of 10Mbps."(Webopedia, 2007). Ethernet is the most popular architecture used today. One advantage to Ethernet is the ease of installation. Ethernet costs less than other network architectures and is easy to use. Ethernet supports many different kinds of networking media, which makes it more popular
1 Text to Text: 2 In the text "The most dangerous game" you are left with many moral dilemmas, wondering what is right and what will happen next. The main characters are Rains ford and General Zaroff, Rains ford is a wealthy author who has a passion for hunting. While General Zaroff also shares the same passion for hunting however to new extents .When Rainsford is left on a deserted island he and Zaroff meet ,Zaroff tells him about his new form of hunting ,because recognizes Rainford form his novels on hunting ,and gives a proposal to his new kind of hunting. Zaroff forces Rainford to scavenge in the jungle, escaping Zaroff and his hounds and servant for three days.
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.
The first topology represented is the Ring topology. A ring topology is a network in which all traffic moves in only one direction because of this the speed is faster than some other topologies, even as network traffic increases. Due to the configuration of a ring topology the resources of the network are available to every device and the cost of setup can be lower than some of the more complicated topologies. However, the configuration of the Ring topology is also a disadvantage. Since a file sent to any device within the network has to pass through every device, if one device fails the entire network goes down. (Ethernetpedia)
Exercise 2.3.2: A network topology is the arrangement of a computer network, how they should be connected.
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.
Taking this class I have learned good amount of terms we use in IT sector. From ch1 and 2 have help me allot more in depth about its technology and mostly understanding how each things work and the pros and cons about security and what are useful gadgets to have. Topology was the term I wasn’t familiar with but the concept was always around me weather at school library or labs and at work place. There is physical and logical topology, physical topology we use at home and mostly see in various work station in our life time. It mostly hardware and how the end devices interconnect. When two computers connect directly with one another without a central device, with a wires it be called physical topology. Logical topology is software and does contrast with physical side but logical define
The current network is a fairly early design called an Ethernet Bus network. A bus network Topology is an architecture in which a set of clients are connected via a shared communications line, called a bus. Each of the 3 sites utilizes the same configuration of
Local area network (LAN) is a wireless network that is mostly used in a work place or small building. To be able to make this work, you will need an access point connected to a switch to create the wireless network. There are different types of hardware components that are used to set a wireless network up such as network adaptors, Ethernet cables and a hub.
The most important lesson Atticus teaches Scout and Jem is that real courage isn’t from physical intimidation, but from a mental standpoint.
This mesh type application of switches provides multiple paths for network traffic to flow. What this means is that if one link in the traffic flow or a switch goes down, traffic can continue to flow using an alternate path. This type of mesh
Separation of system gadgets is accomplished in this star topology. The operation of information transmission is easier because of its tendency of centralization.
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).

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
