Essay Network Topologies

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)

Exercise 2.3.2: A network topology is the arrangement of a computer network, how they should be connected.

In the star arrangement, there's a focal pc or server to that every one of the workstations are specifically joined. Every workstation is by implication associated with each diverse through the focal PC.

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

Star – All computers and devices are connected to a centrally situated hub or switch. The hub or switch collects and distributes the flow of knowledge at intervals the network. It’s higher to use a switch than a hub as a result of a switch transmits the info to the supposed recipient instead of to all or any hosts on a network.

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 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.

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

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.

Separation of system gadgets is accomplished in this star topology. The operation of information transmission is easier because of its tendency of centralization.

In a star network, all cables or nodes are connected to one central core which is the hub. This tends to be the most reliable topology.

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.

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).

All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
