Introduction A Wide Area Network is geographically dispersed telecommunication network. The term distinguishes a broader telecommunication structure from a local area network. Wide area network may be privately owned or rented, but the term usually connotes the inclusion of public network. An intermediate form of network in terms of geography is a metropolitan area network. WAN is communication network that are regional or worldwide in geographic area, with a minimum distance typical of that between
Wide Area Networks The creation of wide area networks links mass communication from people all over the world with a vast variety of different uses. “A wide area network is telecommunications networks covering a large geographic area.” The internet is the biggest example of a wide area network and has influenced our daily lives all around the world. Wide area networks are connected to local area networks to enable computers to share, send, and access information on a larger scale. These recent
relay is a communication method that transfers data by dividing information into packets and sending them over a virtual network. Frame relay is a difficult process to understand and to accomplish. Leased lines, however, is the permanent connection between two stations. Leased lines are simpler to understand and do not take a lot of effort to achieve. According to Computer Networks, frame relay came into existence to overcome the complex protocols caused by slow telephone lines, and expensive computers
Riordan Manufacturing WAN Project The current architecture of the Riordan Manufacturing Company Inc. Wide Area Network (WAN) and network security in place requires updated documentation. The purpose of this paper is to consolidate the existing information into a single format and evaluate the WAN and security documentation for an executive overview. Riordan Manufacturing, Inc. is an industry leader in the field of plastic injection molding. With state-of-the art design capabilities, they create
36 months. It means 36 months x $50K = $1.8 million. Mr. Wooten also had an opportunity to sell his company to Network Solutions. He could only do it after the 90 day no shop clause. 6. How would you respond to the Network Solutions offer? The capital of Image Café was running low. Mr. Wooten was in trouble with his business so If I were Mr. Wooten, I would take full advantage of Network Solutions Offer. I would sell Image Café for $21 millions because I would know that I would not need to worry
private network or LAN. The DMZ is considered more trusted than the Internet but less trusted than the internal network. Many commercial routers use the term DMZ when they are simply bypassing their filters and NAT protection and forwarding all traffic to a specific host. This setup is not a true DMZ although can serve the purpose of one. One way to create a DMZ is with a machine or device that has three NICs (Network Interface Controller) in it one for the WAN connection, one for the DMZ network and
WAN: WAN is a computer network spanning a relatively large geographical area. WAN stands for: Wide area Network. WAN consists of more than two local area networks (LAN) LAN is also a computer network but unlike WAN it spans in a relatively small area such places as a home, school building, office building or computer laboratory. The most well-known or the most popular WAN is the internet. Unlike LAN, WAN is usually not owned by a single organisation or company but exists under distributed or collective
Introduction The purpose of this papers it to examine in detail the operation of one of the wide area network that we discussed in class. This paper discusses the difference between frame relay networks and other point to point networks, advantages, addressing schemes, and different protocols supported. The paper will explain virtual circuits briefly before moving to its other characteristics because they are the key to understanding frame relay concept in general. Other than virtual circuits, we
A network is a group of computers which are linked in order to share resources. These computers may be linked by cables, telephone lines and satellites. There are 2 types of networks, local Area Network (LAN) or Wide Area Network (WAN). Local Area Network is when computers are confined into a small area to and are connected from cables or wireless. LAN can use resources and share them such as files, software, hard disks and peripherals (devices used to input or output information in a computer)
7. How do local area networks (LANs) differ from metropolitan area networks (MANs), wide area networks (WANs), and backbone networks (BNs)? Local Area Network as defined in our textbook is a “group of computers located in the same general area,” (Fitzgerald & Dennis, 2012. p13). LANs is a type of network usually implemented within an office, school or home environment where group of computers are located in proximity with each other or in a small geographic area. Thus, client computers are interconnected
Medical Center data is extremely important to keep very secure. Hackers may have the ability to alter treatments to be initiated to paitients if they are able to alter documents: paitients must be informed therefore and agree with all treatment protocols to be initiated. If patients are correctly informed about their treatments they can be given the ability to remember and know when things have changed. Uninformed patients may not even know the details of their treatments, this cannot happen.
I have decided to pursue the career of a network system administrator or IT professional. Over the last ten years or so computers have become fundamental parts of everyday life, used for a variety of reasons at home, in the workplace, and at schools. Of course every computer user runs into obstacles from time to time, whether it is the blue screen of death, the forgotten password, or the loss of important data. The explosive use of computers has created a high demand for specialists to provide advice
Have you ever thought about what would happen if all the technology that we rely on today suddenly stopped working? To ensure that this never happens there are computer network administrators. Though it may seem like a boring career, there is a lot of responsibility on these people ensuring that there is never a dull moment. To learn what these responsibilities and the more information of the career one would need to look at the history of the career, Job description, the Education and Training
11.1 What is network topology? “Network topology is the arrangement of the various network elements such as node, link, of computer network. Basically, it is topological structure of a network which ether be physically or logically.” 11.4 Why are there multiple LAN standards? There multiple LAN standards because there might be wide range of data rate and transmission that might need to support. For that reason there are a set of standard that are developed by IEEE 802 committee which are accepted
Topologies Mesh A mesh topology typically refers to a Wide Area Network where there are multiple paths connecting multiple sites. A router is used to search multiple paths and determine the best path for the data. Routes are determined by least cost, time of day and performance. A three or four site mesh network is relatively easy to create, whereas it is impractical to set up a mesh network of 100 sites or nodes. Mesh networks are used in Wide Area Networks (WANs) where reliability is important and the
Networks: From The Ground Up A network is merely a series of interrelated components, sharing information, linked by one common lifeline, spanning across a large area. When most people think of networks in the computer sense, cyberspace and the internet are usually types of networks that come to mind. However, these are just small pieces that complete the network puzzle. Many other types of networks include Local Area Networks (LANs), Wide Area Networks (WANs), and also wireless networks
LANs: Local Area Networks Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets
SAN implementation over Gigabit Ethernet A Storage Area Network is virtualized storage. A storage area network (SAN) is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage systems. A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move between servers as they need it. The storage can be added to and removed without requiring the server to be rebooted. The services provided by

Anyone who's run a network operations group knows the frustration that accompanies management inquiries about “our network strategy.” To be successful, a strategic network plan must define the services the network will offer the line operations of the business. Network, in computer science, techniques, physical connections, and computer programs used to link two or more computers. Network users are able to share files, printers, and other resources; send electronic messages; and run programs on other
