Christopher A. Lee Sr. NT1310 Week 3 Assignment.Network Topology Paper Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network.[1][2] Essentially, it is the topological[3] structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical

the Servers they will use mesh topology because if one server goes wrong the other can work it out, very cheap to use and transfer data without any delay .So for server I recommend mesh topology for the 10 servers. If don’t to pay for another network then they can use Star network but in this case they can use fast topology if something goes wrong on hub all the devices can not to internet. But for the room that storing desktop computers, they will use star topology because

network size: LAN and WAN (and MAN) Based on management method: Peer-to-peer and Client/Server Based on topology (connectivity): Bus, Star, Ring … Topologies There are different topologies that make up computer networks. Topology is the physical layout of computers, cables, and other components on a network. Many networks are a combination of the various topologies that we will look at: · Bus · Star · Mesh · Ring Bus Topologies A bus topology uses one cable

to a network topology. Pg 84 link- any cables involved between two devices. Node refers to the devices. 11. State the purpose of a LAN switch. Pg 89 To direct ‘calls’ to the proper location. Kind of like a mail-man 12. Define internet and explain what it is. Pg 91-92 Interconnected networks. A bunch of client-server networks talking to each other. 13. What is the purpose of a device driver? Pg 35 To allow a computer to use a device. 14. Define network topology. Pg 46 logical

CHAPTER 4 1. Why is a focus on information systems insufficient in networking? Because the network professionals often has to focus on the broader business system in which the information system is embedded. 2. Compare trends in network demand and network budgets. The network demand is likely to grow rapidly in the future, just as it has always done in the past. The network budgets are growing very slow 3. What are QoS metrics? (Do not just spell out the acronym.)

Introduction to Networking Unit 2: Assignment 1 Indentifying Network Topologies Identify the major needs and major stakeholders for computer networks and network applications. The major stakeholders for computer networks and network applications are the ones who use it or relay on it to do business. The main stakeholders are the ones who uses the network or applications to get their work done for their company. The next stakeholder is the company or people who rely on the first company to get

Lab 2 Exercise 2.1.1 If one of the five (Media, Interface, Signal, Pattern, and Timing) is missing you will not get a connection. You will not be able to share information. If Media is missing there is no way to transmit the signal. If the Interface is missing there is no way for the computer to access the media to get the connection. If the signal is missing you cannot transmit to get the connection. If the pattern is missing the device cannot communicate with any other device on the network

Topologies and Network Technology NTC/361 Monday, August 8, 2011 Thomas Krawczyk Topologies and network technology In every project, it is important to have a goal, and that goal should be the foundation on which a project team spring into action. The foundation should involve an infrastructural plan, and the usability of the components of the infrastructure. A project plan, as in any other plan, should outline the premise of the project and answer some basic questions like why
