Computer Network Topology Essay

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.

2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations. This system is mostly used in data centers.

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

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.

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.

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

Network Administration I have worked as a computer network administrator for over 5 years. I have worked mostly with networks in a mixed Microsoft Windows NT and Novell Netware environment. I am a Novell Certified Novell Engineer (CNE) and I am a certified Novell GroupWise Administrator. I have taken classes in configuration of Cisco routers. In this essay, I will discuss the definition of a network administrator, the tasks and responsibilities of a network administrator and share a day in the life of a network administrator.

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).

UMUC’s new building in Adelphi, MD will have to provide networking connectivity to students, professors, and staff. In order to begin the process of planning the new network, we will begin by planning the network IP addressing scheme. It is very important that the network IP addressing scheme be clearly defined in order for IT administrators to locate computers promptly. Also, in order to make it easier for the administrators, DHCP (Dynamic Host Configuration Protocol) will be used to assign IP addresses. The organization of the subnet layout will assist the IT administrators as well as making effective use of IP addresses.

You are the network manager of a company that has grown from 10 employees to 100 employees in 12 months. Year 2 projected growth is estimated to be 100 additional employees located at a remote location. The aggressive growth has brought about some unique challenges and opportunities. The company has one remote warehouse and no off-site disaster recovery services or servers. The network design remains a non-redundant, flat topology.

There are two basic types of VSAT networks: Mesh topology networks and star topology networks. A mesh topology network is a point-to-point network consisting of multiple locations and antennas as described above. A star topology network is usually a larger network where multiple equipment sets (antennas and modems) are placed in various locations. These geographically dispersed equipment sets are also referred to as nodes. Each node transmits its signal through a satellite to a larger modem and antenna called a “hub”. A hub modem is a more complex unit compared to those of an individual node and the hub antenna is slightly larger with more power capability (usually 4-11 meters in diameter). In star topologies, each node communicates to the satellite and the satellite communicates to the hub. The hub acts as a

The proposed network is designed for the UMUC new building in Rockville. This new building will have some administrative offices, lecture rooms, library, and computer labs with an open Wi-Fi. This new building will have total six computer labs that will be used for instruction. Each of these labs will have 25 computers, 23 student computers and one instructor computer, one server in the closet and in addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students for doing their own purpose like homework. In Student Computer Lab there will be 30 computers and a server in the closet. There will be 10 computers for student’s use and 5 computers for Library staff in the library so they can access to the library resources for staff use, with the exception of the admissions office, which will have five computers. There will be six class room which will have a computer for instructor’s use. Finally, there will be 7 offices in the building and each of these offices will have one computer. There will be two server rooms, one on the first floor and another one on the second floor. There should be at least 3 separate networks: Administrative, Instructional, and Public. All staff-accessed computers will be on the

Generally, every component in a network is called a node. Each node is further identified by the specific task it performs. A user's node is called a terminal or a workstation. This can be a "dumb" device, meaning it has no operating system, just a monitor and keyboard, or a "smart" node, meaning it can do it's own computing because of an internal central processor.
