Features Of A Network Topology Essay

In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.

The system should also allow users to access the network from anywhere as long as they can verify authenticity. The system should also be able to prevent brute force attacks. The system should also make it possible for admins to see suspicious activity. Overall the components in the system should work as intended, to ensure top notch reliability and availability.

In the design, the topology used is a star topology. The computers in every office or classroom are linked to the central device known as the switch. The star topology leads to the expansion of the network without any disruption. This defines the use of a hub, a router or a switch to interconnect various computers together. All the workstations in this topology are connected with a connection of point-to-point to the central device. The data is first passed through the primary device before reaching the planned destination. Hub controls and manages the whole network. The hubs connect several nodes that are present in the star system. The hub acts as the signal booster (Elhakeem, 2010).

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

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)

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.

A firewall will be used so that UN authorized users will be restricted. Parts of security will be different user account and password for each member.

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

• A failure in any cable or device breaks the loop and can take down the

“Right now, it’s an industry dedicated to one thing. Profit.” This quote by author, Paddy Chayefsky, perfectly sums up the motives behind the movie “Network.” From hiring soothsayers to risking a man’s mental heath for the sake of a successful television program, the characters in “Network” have truly been blinded by fame and top ratings. This satire fiercely describes just how far a television network will go to achieve such accomplishments.

ESET NOD32 Antivirus- an Antivirus is software that is used to prevent, detect, and remove malicious computer programs. ESET NOD32 Antivirus is a good choice since it also acts against other types of malware such as worm, Trojan horses, backdoors, and spyware. The ESET NOD32 Antivirus 6 that I will utilize

When a system transmits data, it sends the data to the central device. The central device, which was a hub when the star network first came out, then broadcasts the transmission out to all of the connected devices. This set-up reduces the chance of a network failure because if one node goes down, the network will still be up and operational. However, if the central device goes down, then the entire network will go down. The use of hubs has been removed from modern day networks because they are essentially dumb devices. Since the hub will forward information to every device that is connected to it, the chances of a collision occurring is pretty high. A switch will learn the MAC address of the systems that is connected to it. Once a switch has learned the MAC addresses of the systems that are connected, it will send information that is intended for that system only to the port that the system is connected to. This smart filtering that the switch performs drastically helps to eliminate collisions on the star network. The star topology is the most popular choice of networks due the easiness of setup and the lower costs of equipment. The star network can use twisted pair, fiber, or coaxial cable as its network

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).

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.

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
