...World Wide Web Consortium (W3C) has ensured that its specifications can be implemented on a royalty- free basis. Standards will be maintained by not for profit organizations, and it’s ongoing development. Some of the benefits are companies are not locked into a specific technology and/or vendor. This makes it easy to use different forms of communications and technologies with in one company or business. It also makes the exchange and the interchange of data a lot smoother. 2) Layered architecture will help accelerate the application development of processes. A model is defined as a set of elements, (forms, queries, methods or fields) captured in metadata and stored in specific layers of a model store. This allows less code writing and faster solutions. Large and complex systems that are constantly being updated, the ability to be able to change the implementation of a service without affecting the other components of the system. 3) A protocol is a set of rules that defines how things are to be done, a standard method that’s agreed upon for passing or transmitting data between devices. The internet is an example of successful protocol-based system in which the implementation of key qualities of protocols such as error and correction and message formatting is utilized across a wide variety of hardware and software. 4) There are four different types of networks: a) Local area network (LAN) is a network that interconnects computers in a limited area such as...

...current network and ways to improve the efficiency and effectiveness of our network system. The following problems have been researched and addressed in the following pages: 1. Toll charges are currently being applied to communications between Los Angeles (LA) and Miami offices 2. Network upgrade needs to be implemented to remain competitive a. Eliminate all interoffice toll charges b. No adverse effects on the Wide Area Network (WAN) c. Diagram the network layout The current network has been around for a while and is in desperate need of upgrade. It is my belief that the upgrade should begin at the local area networks (LANs) in both Miami and LA. Only by upgrading both offices equally, can we expect to achieve the efficiency which we desire. The recommended changes should be enough to lower the collective overhead and operational expenses while preparing the company for continued future growth. To implement this growth, many challenges will be faced while creating a WAN solution for this business. The primary focus areas consist of the ability to connect when desired and the security and reliability of our connections while maintaining cost effectiveness. Wireless WAN connectivity from a reliable server can play a very important part in the implementation of these challenges. A broadband connection in addition to wireless WAN...

...Raven Williams January 14, 2016 NT: 1210 Intro to Networking 1. What are open standards, and what, if any, are the advantages of such standards? Open Standards" are standards made available to the general public and are developed (or approved) and maintained via a collaborative and consensus driven process. "Open Standards" facilitate interoperability and data exchange among different products or services and are intended for widespread adoption. 2. In general, why would a layered architecture be viewed as beneficial? The Benefits of Layered Application Other applications will be able to reuse the functionality exposed by your layers. You will be able to distribute your layers over multiple physical tiers. This can make a very good impact on your application by Improving performance (sometimes), scalability and fault tolerance. The maintenance of your application is easier because of the low coupling between layers. Adding more functionality to your application is made easier. Layers make your application more testable. Building a well formed layers makes the orientation in your application easier. Having your application not layered means that you have to deal with all security threats in one place which is very difficult. Having your application distributed to layers makes it much easier for design and implement Without a good deployment plan it is not trivial to distribute your layers over multiple physical tiers in distributed computing. You need...

...threats. Networking hardware is hardware that is used to help work stations connect to a server. What will be used on the wireless network will be the WPA2 encryption standard, Special hardware will be implemented when using WPA2 to work properly. The hardware that will be chosen would be routers, and switches. By using both along with firewall protection it will help protect not only the network but those networks that use Ethernet cabling. Each desktop will run Norton Anti-Virus. Norton will run the update programs automatically whenever there is an update to be made. This software along with the firewall will keep Kudler’s Fine Foods network safe and secure. Security Concerns Security should be the top priority for the network within an organization, and for the growth of the business. One of the concerns would be the mobile devices on the network. Smartphones and IPhone are effectively small computers and face many of those same threats that personal computers or laptops risk for those organizations. One thing that Kudler’s Fine Foods should install would be Norton Mobile Security. This offers an advance antitheft feature that will let you remotely lock your phone if it is lost or stolen, remotely erase sensitive information, block fraudulent websites designed to trick you into revealing personal information, and the Norton Mobile Security automatically scans all apps and app updates you download to your phone for threats.

...that is almost magical. Telecommunications and computer networking have vastly increased our options on how and what we communicate, they have physically constrained us by leashing us with a physical wire to the network. But wireless communications brings us back to a form of communications that is inherently natural to us. There are three main types of networks that will be discussed on this paper, namely Local Area Network (LAN), Control Area Network (CAN), and Wide Area Network (WAN) (Rysavy, 2013). The purpose of this paper is to know what each of these networks are, how they work, and how each of them can be implemented. LAN Network: This is a data communications network connecting terminals, computers and printers within a building or other geographical limited areas. These devices could be connected through wired cables or wireless links. Ethernet, Token Ring and Wireless LAN using IEEE 802.11 are examples of standard LAN technologies. Local Area Network could be interconnected using Wide Area Network (WAN) or Metropolitan Area Network (MAN) technologies. The common WAN technologies include TCP/IP, ATM, and Frame Relay. LANs are traditionally used to connect a group of people who are in the same local area. However, the working group are becoming more geographically distributed in today's working environment, making virtual LAN. VLAN technologies are defined for people in different places to share the same networking resource (Edraw visualization solutions, 2015). Implementing...

...Networking When you have two or more computers connected to each other, you have a network. The purpose of a network is to enable the sharing of files and information between multiple systems. The Internet could be described as a global network of networks. Computer networks can be connected through cables, such as Ethernet cables or phone lines, or wirelessly, using wireless networking cards that send and receive data through the air. LAN - Local Area Network A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings. InTCP/IP networking, a LAN is often but not always implemented as a single IP subnet. In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring WAN - Wide Area Network As the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. A WAN is a geographically-dispersed collection of LANs. A network device called a routerconnects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address. A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by...

...Link layers of the OSI, performing any type of serial interface. This technology was developed at an attempt to resolve some of the communication problems that the other protocols would not. There was an increased need for higher speeds, an increased need for larger bandwidth efficiency, an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs. The Frame relay evolved passed the X.25 as a less careful, but less burdensome protocol designed to transmit packets across a network. (Horton, 2010) Frame relay is known all around the world in many different networks. There are many terms that describe and refer to Frame relay and Wide Area Networking in telecommunications. These terms are also noted when referring to Local Area Networking as well. The table below describes these terms. (Horton, 2010) Table 1 – Frame Relay Terms CIR Committed Information Rate – the minimum level of throughput as guaranteed by the service provider.

...a high level network for ABC Company we will provide a basic written infrastructure of both the local and wide area networks we are to build for them, being such an early stage this document is subject to change. This design includes the infrastructure for the corporate headquarters located in San Francisco, as well as the other design centers in Detroit, Paris, Tokyo, and Sao Paulo. We then follow up by explaining the infrastructure of the sales offices, which may not require as high grade of equipment as the design centers depending on its requirements. Finishing with the overview of the entire wide area network, connecting each site to the corporate headquarters which is where we will begin our design. The corporate office being the main headquarters will include many services such as file, print, email, directory, and application. These services will be separated onto at least two different servers due to the constant strain we may see from directory and email services. If necessary we will implement an application server as well to run any in-house programs the company may be familiar with. We also suggest the use of a database server dedicated to storing and providing access to its information throughout the network, which would also need to maintain a backup located nearby or even off site. Finally we will also implement a PBX server in order to provide world-wide telecommunication through VoIP software and the use of the PSTN. All of the offices will be cabled using...

...CSC621 Business Data Communications and Networking Chapter 1: Introduction to Data Communication Submitted By: Sreedhar Thotakuri Student ID – Sthota9299 Sullivan Univeristy Professor: Dr. Nathan P. Johnson Answers to End-of-Chapter Questions 7. How do LANs differ from MANs, WANs, and BNs? Answer: A Local Area Network (LANs) are a group of computers located in the same general Area usually in a small defined area like one floor or work area and uses shared LANs support high-speed data transmission compared with standard telephone circuits, commonly operating 100 million bits per second (100 Mbps). (Fitzgerald, Dennis, & Durcikova, 2012) A Metropolitan area network (MANs) covers a city or county area usually span between 3 and 30 miles, MAN is provided by common carriers like telephone companies. MANs data transmission usually ranges from 64 Kbps t0 100 Mbps. (Fitzgerald, 2012). Wide area network (WAN) covers city, state or national boundaries and it covers hundreds or thousands of miles and it provides data transmission ranging from 64kbps to 10Gbps(Fitzgerald, 2012). Back bone network (BN) a larger, central network which connects several LANS, MANs, WANs and other BNs and it covers from hundreds of feet to several miles and the data transmission ranges from 100 to 1,000 Mbps. (Fitzgerald, 2012). 14. Explain how a message is transmitted from one computer to another using layers. Answer. Network user uses application layer which is...

...3.1.2 Types of Computer Networks Computer networks are classified based on the geographical length. A network can be as small as the distance between a mobile phone and its Bluetooth headphone. Also it can be as large as the internet itself. It covers the whole geographical world. Types of Networks • LAN • WAN • MAN (i) LAN (Local Area Network) A local area network is a self-contained network. It lengths a small area, such as a single building, floor, or a room. In LAN, all the nodes and segments are connected directly with short range wireless technology or cables. Each computer in a LAN has its own CPU. It executes the programs. It also access the data and devices anywhere on the LAN. Through LAN many users can share expensive devices, such as laser printers, as well as data. The LAN is used by the users to communicate with each other. They communicate through emails or by engaging in chat sessions....

...Data Communications The 4th Annual Technology Trade Show is slowly approaching. We are preparing to get things in order for the company’s booth. Marketing managers are in the process of determining what displays we will be presenting. The specified equipment will be all of the 2015 models of the T-21. As a marketing manager, I have developed an Excel spreadsheet that will track booth components, equipment, shippers and shipments. The Excel file is named “2015 Trade Booth” located on the company SharePoint site. The excel spreadsheet has five sheets that are labeled with the approximate label. The tab labeled “Events” has all of the information for the Trade Show. This tab has an info form imported from Word that needs to be filled out by all vendors, suppliers, and buyers for the event. Once the form is completed, it should be entered into the 2015 Trade Booth Access program. Entering the vendors, suppliers, and buyers information in the Access program will link information to the equipment, supplies, and shippers and shipment information. Using Access for the database allows the company to store vast amounts of information while importing and exporting files to or from Word, Excel and PowerPoint. One disadvantage with using Access last, was connection problems with Word and Excel, which made it impossible to track data. This year, only one person will enter data and export/import files. Access is a great example of a personal database. A personal database is a DBMS product...

...two main types of networks are LAN and WAN. LAN stands for local area network, and WAN stands for wide area network. According to our text “A local area network (LAN) is a data communication system consisting of several devices such as computers and printers.” (The McGraw−Hill Companies, 2006). These devices are physically connected to one another by cables, wireless media, or infrared links. Any network within a building or several that are next to each other is a LAN. A WAN, also known as a wide area network is made up of two or more LAN’s geographically connected. An example of a WAN is when a company or business located in one place has its main offices in one place and other smaller parts of the company in other places all data is shared within the network. There are also three types of hybrid networks, CAN’s, MAN’s, and HAN’s. A CAN or campus area network is like a LAN but on a bigger scale and more diversified, allowing different campus offices and organizations to be linked. For example, at a college the registrar’s office is connected to the bursar’s office. MAN’s which are metropolitan area networks are a large type of network that connects many corporate LANs together. These are not owned just by one entity, they are maintained by a group or company that that sells its networking service to corporate customers. A MAN can also provide a shared connection to other networks using a WAN link. A home area network , or HAN is a home based network, as in one for personal...
