Kudler Fine Foods NTC360 11/27/12 University of Phoenix Kudler Fine Foods Now that the Network design stage is complete‚ the team must now determine the hardware and software needed to bring the network design to life. As discussed the backbone of Kudler’s Fine Foods network will be a routed network with LANs and a WAN. IN this case the LAN or Local Area Network will be everything Kudler Fine foods have on the internal side of its routers and firewalls. The WAN or Wide Area Network will be

ISO-OSI 7-Layer Network Architecture This lecture introduces the ISO-OSI layered architecture of Networks. According to the ISO standards‚ networks have been divided into 7 layers depending on the complexity of the functionality each of these layers provide. The detailed description of each of these layers is given in the notes below. We will first list the layers as defined by the standard in the increasing order of function complexity: 1. Physical Layer 2. Data Link Layer 3. Network Layer

Area Network. When a frame is sent the format of the frame has to be understood by the destination NIC. If the format of the frames were different then the two devices could not communicate. Exercise 4.1.2 The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your textbook and Internet research to support your answer. Copper wire is used to power appliances which

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which

Charles H. West III Week 8 Assignment 4 CIS499 Project Deliverable 5 Dr‚ James Manning August 25‚ 2013 Objective To provide the best desktop connectivity for end users we would use twisted cable to connect to the Ethernet and will bring the 8 pin cables in use. To provide the fastest possible throughput there will be the use twisted cable which will transfer the data between nodes and devices very quickly. To provide security for the pay roll department effective firewalls will be used at

VLAN Paper Stephen C Wilburth Jr NTC 249 December 10th 2012 Chen Li VLAN Paper A VLAN (virtual local area network) is a logical grouping of network devices (servers‚ workstation‚ laptops‚ etc.) that generally have something in common‚ such as the same department or access to a particular server. Although devices in VLANs are virtually separated from each other by being placed on different segments‚ they can still communicate with each other as if they were on the same segment. VLANs are a

FIBER TO THE HOME: THE NEW EMPOWERMENT abstract: In order to offer future higher bandwidth applications‚ the choice for a fiber to the home (FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from
