...does not say how congested the network is, I will assume that the entire network will be upgraded to include the switches, and routers. The network is already running at 10baseT so I will also assume that the cabling is Cat5e that can handle 1 Gbps and I will not be upgrading the cable drops. Due to the offices and the personnel in the offices, I will create VLAN’s for several of the operating units. I will create the following VLAN’s: VLAN 1 (Accounting): Accounts Receivable, Accounts Payable, Sales and Marketing, Payroll VLAN 2 (Administration): Human Resources, Customer Service, President, Security, Mail room VLAN 3: (Operations) Agent Operations, Intrastate Operations, Interstate Operations VLAN 4 (Vehicle Management): Fleet Maintenance, Dispatch VLAN 5 (Information Technology): Information services, Data Processing, conference room I would purchase Layer 3 VLAN switches and a Router. Each VLAN would be connected to each other VLAN switch and the router using 1Gbps backbone circuits. The router would be responsible for Internet traffic and the VLAN switches would be responsible for managing the traffic within the VLAN and between VLAN’s. The connections to the individual hosts would be primarily with 100Mbps connections (NIC’s). Any servers (mail, database, application, etc.) would be connected using 1Gbps connections. The network would run on Ethernet with TCP/IP as the primary data protocol. The second assigned problem, exercise 9-1 on page 330 asks for a description...

...it was first introduced many years ago. Media selection is often affected by the network standards that you want to implement. The type of media required for specific devices is dependent on the network hardware. The two main types of transmission media include: cable and free space. Cable had long been the commonly implemented media for data transmission (telephone, television, Computers). Even Though the current trend is towards wireless implementations, cable is generally still needed for backbones and certain types of networks. The three basic types of cables are: Twisted pair. Coaxial. Fiber optic. One of the basic ways to get started was a dial-up connection internet, which has been around since the 1980’s. Dial-up internet access may be used where other forms are not available or the cost is too high, as in rural or very remote areas. This brings us to Twisted-pair cables, which would fall under one of the four categories Category 1- Traditional telephone cable, not designed for data. Supports low speed communication, such as dial-up lines Category 2- Contains two-twisted pair of cables and supports data transmission and supports up to 4Mbps Category 3- contains four twisted pair of cable and supports up to 16Mbps Category 4- contains four twisted pair of cable and supports up to 20Mbps As Technology grew, the networking system had to also grow along with it. Network Cables would have to be updated and DSL and Broadband would come into the picture...

DS0 ≈ 64 Kbits/sec, DS1≈1.544 Mbits/sec, DS≈6.312Mbit/sec DS3≈ 44.736 Mbits/sec, OC-1≈ 51.84 Mbits/sec Define each of the following terms and explain what each is used for. -DS0 - Digital Signal 0 (DS0) is a basic digital signaling rate of 64 kbit/s, corresponding to the capacity of one voice-frequency-equivalent channel.[1] The DS0 rate was introduced to carry a single digitized voice call. For a typical phone call, the audio sound is digitized at an 8 kHz sample rate using 8-bit pulse-code modulation for each of the 8000 samples per second. This resulted in a data rate of 64 kbit/s. To limit the number of wires required between two involved in exchanging voice calls, a system was built in which multiple DS0s are multiplexed together on higher capacity circuits. -DS1 Digital Signal 1 (DS1) High-capacity DS1 Service is known as a fundamental building block of many networks. It is a digital, point-to-point, private line service that provides high-speed bulk transport for voice, data or video traffic. Use the entire circuit for single, high-speed bandwidth applications, or divide or multiplex, your DS1 into multiple channels. -DS3 Digital Signal 3( DS3) Service offers a reliable, all-purpose digital connection for extremely high volume requirements that can easily connect your DS1 circuits. DS3 Service transmits video, data, and voice at speeds...

West is vice president and director of Governance Studies and holds the Douglas Dillon Chair. He is founding director of the Center for Technology Innovation at Brookings. West’s studies include technology policy, electronic government, and mass media. ducation is at a critical juncture in the United States. It is vital for workforce development and economic prosperity, yet is in need of serious reform. American education was designed for agrarian and industrial eras, and does not provide all the skills needed for a 21st century economy.1 This creates major problems for young people about to enter the laborforce. Mobile learning represents a way to address a number of our educational problems. Devices such as smart phones and tablets enable innovation and help students, teachers, and parents gain access to digital content and personalized assessment vital for a post-industrial world. Mobile devices, used in conjunction with near universal 4G/3G wireless connectivity, are essential tools to improve learning for students. As noted by Irwin Jacobs, the founding chairman of Qualcomm, Inc., “always on, always connected mobile devices in the hands of students has the potential to dramatically improve educational outcomes.”2 This paper, part of our Mobile Economy Project, looks at ways that mobile devices with cellular connectivity...

COURSE DESCRIPTION Supply Chain Management involves the flows of materials and information among all of the firms that contribute value to a product, from the source of raw materials to end customers. We will integrate issues from marketing (channels of distribution), logistics, and operations management to develop a broad understanding of a supply chain. By taking a strategic perspective, we will focus on relatively long term decisions involving the investment in productive resources, configuration of processes, product designs, and development of parterships with suppliers and channels of distribution. Although the development of analytical tools is not one of the primary objectives of the course, students should be comfortable with quantitative analysis. By the end of the course, you should have developed an appreciation for the major strategic issues trade-offs in supply chain management as well as the ability to use conceptual frameworks to make decisions.

...us to live and work in ways never before possible, offering us flexibility, mobility and a link to our environment 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...

...CHAPTER 1 Problem and its Background Introduction The internet is a global linking of computers that allows information transfer. The internet was established in the early 1960’s by the U.S Department of Defense primarily for military purposes. Since then the continual improvement of internet technology has provided an extraordinary level of public accessibility to a wide range forms of communication. Due to the development once spread of cheaper and more user-friendly computer and technology software, the use of internet has increase dramatically. Internet surfing is very useful to the lives of people. It is either a good or bad influence. It depends on how you manage of using it. These advantages or disadvantages occur on the actions we done. As internet surfing crosses the lives of many people, we teenagers usually become addicted to it. Most of them spend time on internet. The addiction leads to destruction to the academic performance of a person. In result, that person fails to comply the requirements given with him. This kind of access on the internet that we have makes our life easier. It makes our life easier (especially to students who needs information) and saves a lot of time. It also enables us to know and be updated on what is the current happening of the world. Internet is more efficient and quick. It is also a way of communicating another people. The internet has brought a lot of people closer together. There are many benefits associated with internet...

...Carlyle Brown Network Protocols and Standards Week 3 Homework 1. When was the first major standard describing a structured cabling system released? c. 1995 2. Why is balance an issue in UTP cables, and what is TCL? i. The balance or symmetry of the signal over the wire pairs helps minimize unwanted leakage of the signal. ii. TCL - Transverse Conversion Loss - The TCL measurement is obtained by applying a common-mode signal to the input and measuring the differential signal level on the output. a. TCL is sometimes called LCL (Longitudinal Conversion Loss). The ELTCLT value (expressed in dB) is the difference between the TCTL and the differential mode insertion loss of the pair being measured. TCTL is the loss from a balanced signal at the near-end to the unbalanced signal at the far end. Section 2-2 1. When was the first major standard describing a structured cabling system released? c. 1995 2. What doe EIA and TIA stand for? i. EIA – Electronics Industries Alliance ii.

...One of the first items to clear up about this topic is when talking about wireless communications we are just not talking about wireless computers networks. Wireless communications also covers wireless phone networks as well as our wireless computer networks. While writing this paper I will try to keep it on just the wireless computer networks, but you will have to keep in mind that this all was started with the telephone and branched out toward computers and other handheld devices. Me like everyone else probably had never really look at wireless as a very vast network which started in 1876 when the phone was invented by Alexander Graham. In 1877, Charles Williams of Somerville Ma had the first private telephone was installed in the home. Four years later over 47,850 telephones were in use in the U.S. (Fowler, 2009). This was the start of the evolution of Wi-Fi, Guglielmo Marconi, an Italian inventor took it a step closer nine years later, and he proved the feasibility of radio communications by sending and receiving the first radio signal. Then in 1869, the first wireless signal across the English Channel was flasher by Marconi. (Fowler, 2009) This should not be confused with the Birth of Telecommunication as some people have linked Telecommunication with wireless communications as John M Shea, an associate Professor of electrical and Computer Engineering from the University of Florida did in an article were he stated in “The History of Wireless Communications” that...

Argue a position as to whether or not the meaning of leadership has changed significantly. One aspect that has not change significantly in leadership within organizations is their ability to work hard and their commitment to the success of their organizations. On the other hand, plenty of changes have risen due to changes in technology, the growing number of networks between organizations and the extension to other countries. Globalization has been a rapidly element that keep companies in evolving changes due to difference in cultures and other factors. Increasingly, groups of companies collaborate to investigate new opportunities and exploit new markets. In this vulnerable economic environment is essential to be able to adapt to constant changes in order to find the best solution possible. “Technology brings new surprises every day, some that can shake up entire industries in a matter of months. With the Internet and the rise of social media, consumers, media and other stakeholders have gained incredible power, which they readily use to reward or punish companies often at lightning speed” (Stephenson, July/August). The amount of changes faced by organizations leaders has requires of them to be culturally competent and inclusive. Leader’s job is one of...
