LAN / WAN Research Project

You have just begun working as a networking consultant with MTI Technologies Inc.
One of your first tasks is to help troubleshoot a small Ethernet network at a tax preparation office in the city of Chicago. The backbone of this network consists of six hubs connected in a bus fashion. Three of the hubs service workgroups of 10 workstations each. One of the hubs services two file servers and two shared printers. In anticipation of tax season and a heavier workload, the organization recently upgraded its network from 10BaseT to100BaseT. However, they have not seen any of the performance increases they expected. Before even visiting the firm, what can you suggest as reasons for the less than optimal performance?

I would inform them that they might have a NIC card that is not capable of 100baseT, this would make all the other NIC cards run on 10baseT regardless of it’s capability. I would suggest that they purchase a new NIC card and I would inform them that they need to update their drivers whenever they do upgrades.
The network managers at the tax preparation office have followed your advice on reconfiguring the network, and as a result, the network is now running more smoothly. However, they have realized that their Internet connection is too slow. They have been using a dial-up BRI
ISDN connection. They want to spend no more than $250 per month on an Internet connection
(not including installation fees). They also need a transmission method with fairly good security and a guarantee of adequate throughput during the daytime hours. What solution can you recommend that will offer them the most throughput at this cost?

I would recommend that they purchase a router and upgrade their internet connection to frame-relay PVC at 256 kbps, which would be giving them double the speed they currently have, plus with the…...

Lans and Wans

...hardware and software needed to create and secure the networks. Each location will be set up with its own Wireless local area connection and they will all utilize the Internet to provide a Wide Area connection for the company as a whole. LAN, WAN and Wireless technologies Local Area Networks, or LANs, are a grouping of computers networked together in a generally small geographic area. LAN technology refers to the hardware and software used to create a local area network. The most common wired methods are Ethernet and Token Ring, and WLAN technologies using IEEE 802.11. WAN or Wide Area Network technologies include ATM. TCP/IP, and Frame Relay to connect and transfer data across large distances. Using a cable such as an Ethernet cable computers on a LAN are required to share the network when passing data packets back and forth. Before sending data across the network each computer checks the line for other transmissions. If the line is clear the computer sends the data, if not the computer waits. This method is called CSMA/CD. Wireless LANs or WLANs use RF signals to transmit data across the network. Every computer on a wireless local area network share the same frequency and take turns sending data just like using a cable. Wireless LANs use CSMA/CA to check for an open line of communication to it intended target. The sending device will send out a signal to the receiving device called a Request to Send. If the receiving device is available it will send a clear to......

...LAN, MAN and WAN Student Name University Network Telecommunication Professor Name October 21, 2013 LAN, MAN and WAN Computer networking is simply the communication between two or more computers that allow them to share information and hardware resources. This is really one of the most important contributions to the information age since personal computers were invented. The connection and communication of just two computers exchanging data and devices is the most fundamental of networking. The computer systems may communicate over a computer network and share their resources (Computer Network, 2009). A computer network can be wire and or wireless. When a network is wired, it uses cables to connect group of computers together to enable data communication. Wireless networks allow computers to communicate by using radio signals, so the computers aren't restricted by physical cables (Lowe, 2011). For example, it uses bluetooth, infrared rays and radio waves to send and receive signals over the network. Peer-to-peer (p2p) and client-server are the two computer networks in use today. In a p2p network, every computer has the same or equal capabilities and responsibilities. And with a client server it is nothing like peer-to-peer, some computers are the clients that request for resources and the servers make available the requested resources. There are many categories of computer networking, but the most common are local area network (LAN), metropolitan area......

Lan - to - Wan Domain

...Michael Bearcroft Week 4 Lab 2 Part 1 Introduction The LAN-to-WAN Domain provides Internet access for the entire organization and acts as the entry/exit point for the wide area network (WAN). This domain is where all data travels into and out of the IT infrastructure. There are many threats and risks here, as the attack could come from inside the network or it could be trying to get into the network. Threats With this domain as the buffer between two other domains it gets the majority of the traffic through it. Some of the treats, risks, and vulnerabilities are as follows. Threats from people, this could be misconfigured equipment, equipment not being used correctly, unauthorized use, use of personally owned software/hardware. There are also viruses, Trojans, and network worms that can inflict damage on the network. Some of the physical threats are fire, water, electrical disturbances, and hardware failures. Mitigation Here is some of the ways in which the threats to the domain can be mitigated. Security training for the employees, so they will know what to do in specific scenarios. Security training is mandated by the Computer Security Act of 1987, so it’s not just a good idea but a requirement. Strict personnel screening by the HR department will also screen out any personnel that could cause issues in the future. User Identification and authentication is another way to keep the LAN – to – WAN domain safe. Another important safeguard is encryption, if the......

Lan, Man and Wan Network Topologies topologies, but the three most common types are LANs, MANs, and WANs. The LAN topology is probably the most common of the three. The MAN and WAN topologies are used but not nearly as much as the LAN topology is, although the WAN is starting to be used more and more because of the growing population of networks. The LAN (Local Area Network) is used so much because it is used in small areas. Small businesses use LANs a great deal because they are small and they wouldnt need a WAN or a MAN because there business is usually ran out of one or maybe two buildings. You will usually find LANs in buildings, schools, and even in homes at times. Some buildings even have multiple LAN's in them for certain purposes. When designing the layout of a LAN, the party can choose from a selection of different technologies on which to base the main part of their LAN. The technology choices that the party adopts will be a critical part in the way their LAN performs. Two important LAN setups are a network based on Ethernet or Token Ring technology. Besides operating in a small space, LANs have some other distinctive features. LANs are typically owned, controlled, and managed by a single person or organization. A WAN (wide area network) goes across large physical distance. Many times a WAN will go almost around most of the world! The most popular WAN is the Internet. The Internet is one big huge WAN and it is also the most used WAN. A WAN is basically a dispersed collection of LAN's.......

...Project Research Paper RES/351 Teyronn Jackson Julie Bonner Project Research Paper Today, there is a growing need for more skilled maintainers to perform maintenance on military aircraft. There are multiple airframes and platforms across the military that are suffering from not having the manpower to support the maintenance needs that are required for the daily upkeep of these sophisticated weapons systems. We intend to address this growing concern by analyzing the needs based on the airframe, type model and series of each platform. Because there are so many different platforms across the different branches of the military, this research will take will be divided into teams of personnel who are designated subject matter experts for performing task that are required to maintain the individual systems of each aircraft. Other items that we intend to address during the process of this research include, but are not limited to unethical behavior and the effects it will have on the individual as well as the organization and society. We will also examine courses of action to be taken to address unethical behavior and what can be done to monitor it so as to prevent it from reoccurring. We intend to deglamorize this behavior as much as possible by addressing it as quickly as possible and encouraging the reporting of any actions that may be a clear indication of unethical behavior during the process of performing this research. Safety should always be paramount while......

...Research Project According to Alexandra Zavis, Christine Mai-Duc, and Tina Susman in the Lexington Herald Leader, published on October 23, 2014, in the article titled “Canada’s Parliament under Fire”, they cover the story of the recent shooting in Canada’s capital city of Ottawa. This article accurately summarized the events surrounding the instance where a shooter had killed a soldier pulling guard duty at the war memorial, and then proceeded to the foyer of the parliament offices where he was stopped by a hail of gunfire. There were a few things that made this article interesting. One major part that stood out was that Canada’s “high-risk traveler” watch list has 90 people on it (Zavis, Mai-Duc and Susman). This sounds like an awfully low number considering the US probably has thousands. To me it would seem you could afford to assign 90 agents to follow these “high-risk” individuals at all times. This article was a pretty quick and easy read. It was laid out in a good chronological order with added quotes from witnesses in the area which helped it flow well. The facts have been confirmed by numerous sources including those witnesses. Another interesting note is where the soldier who was killed had been identified by a friend who had recognized him in television video of paramedics trying to save his life (Zavis, Mai-Duc and Susman). The audience the authors were targeting is just about everyone who has heard about the shootings and might not have known any of the......

...Local are networks (LAN) is a computer network covering a small geographic area, like a home, office, school, or group of buildings. Has a High speed (1000 mbps) Tends to use certain connectivity technologies, primarily Ethernet and Token Ring. LANs tend to have fewer problems associated with them, as there are smaller numbers of systems to deal with. Wide area network (WAN) is a computer network that covers a broad area. It does have slower speeds of about 150 mbps. WANs tend to use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances Differences between (LAN) & (WAN) (LAN) is typically owned and managed by a single company or organization. LAN also experiences fewer data transmission errors and overall fewer problems as a whole as opposed to WAN. WAN has a high cost maintenance and lower bandwidth. In conclusion the major differences are going to be cost, efficiency and coverage Describe common physical topologies and a logical topology : Physical topology refers to how the network is wired it can be either a ring topology where all the hosts are connected together or a bus topology where there is a network medium and each host connects to that medium by wire. A logical topology in the other hand governs how the network is going to work. For example all the hosts in the network are connected through a central connecting point that’s the physical topology however the way the protocols and hardware are designed to......

As you see in this type of situation they are dealing with a LAN a local area network and of course they do not really need anything that is incredibly expensive. The first thing that they want to do is simply get a Router from a telephone company and of course a switch that has about 4 to 5 ports in this case would be super great. After this, they will be easily on the Internet running at great speeds (Please do not forget upgrade your driver cards!!!!!!) ------------------------------------------------- The Internet connection you have selected for the tax preparation firm is working well.
