Cite the sources from which you retrieved the information to complete the comparison. UTP-Defines a cable that can carry data up to 100 Mbps. The signaling frequency of this cable is up to 100 MHz. Cheapest form of cable available for networking purposes. Easy to handle and install. Highly prone to external interference like EMI and RFI. Highly prone to crosstalk. Unable to provide secured transmission of data. Coaxial (Thinnet) 185m 100 Mbps Low Uses thin cabling, low hardware costs Difficult to troubleshoot, difficult to maintain. Coaxial (Thicknet) 500m 100 Mbps directly connects computers and it costs more. Multimode cables are less expensive to operate, install and maintain than single-mode cables. However, they are much more limited in both speed and distance. For instance, the maximum speed of a multimode cable is 10GB, but only up to a distance of 300 meters. Up to 2 kilometers, it is only capable of transmitting at 100Mbit. Beyond that, its transfer speed becomes negligible. This limitation is negated by the fact that its maximum speed is sufficient for the environment that it is most often used in. Singlemode cable provides less signal attenuation, higher transmissions speeds, and up to 50 times greater transmission distance than multimode cable. Singlemode cable can transmit data at terabits per second over 100km without......

Use your textbook or Internet research to support your answer. The Physical layer is something simple like wiring, fiber and network cards. Devices that allow communication between the OSI networks. Data link layer is the Ethernet, among other protocols; we're keeping this simple remember. The most important take-away from layer 2 is that you should understand what a bridge is. Switches, as they're called nowadays, are bridges. Network layer is an IP address because you're dealing with layer 3 and "packets" instead of layer 2's "frames." IP is part of layer 3, along with some routing protocols, and ARP (Address Resolution Protocol). Transport layer handles messaging units which is also called packets. When you're talking about specific protocols, like TCP, they're "segments" or "datagrams" in UDP. This layer is responsible for getting the entire message to keep track of fragmentation. Session layer is Network Basic Input/output System model allowing applications on separate computers to communicate over a local area network. The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

What is the drawback to having only a single printer? What is the cost of having two additional backup printers for the office compared to having individual printers? How many shared printers can be purchased and still be less expensive than individual printers? It would cost $3,900 if each user had their own printer V.S. buying a high capacity single printer for $500. On top of that if ink cartridges cost around $32.00 dollars apiece for each printer cartridge. It would cost a total of $960 for ink cartridges for all 30 printers. If a single printer was connected to a single workstation then it would be only tied to that workstation. No other users would be able to use printer connected to the workstation. The cost of having two backup printers would depend on what type of printers. There are two known types of printers one LaserJet or standard color ink printers. LaserJet printers can run around $500 each V.S. $120-$150 for a standard color printer. Still the cost of having two additional backup printers is less than having each workstation have their own.

...NT1210 Lab 2.3 Network types and Topolgies Exercise 2.3.1 Briefly define LAN, MAN, PAN, and WAN. What is the critical distinction for these networks? LAN=Local Area Network. Which is a computer network that links devices within a building or group of adjacent buildings MAN=Short for Metropolitan Area Network, a data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media. WAN=Wide Area Network. A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet. PAN=PAN is short for Personal Area Network Based on the electric-field transmission medium,  is an IBM technology that allows individuals to exchange data with a simple touch or grasp, such as a handshake. A PAN user is equipped with a receiver and a transmitter, which constantly sends infinitesimal data-carrying currents -- in the 0.1-1 MHz band -- through the body and picks up currents when in very close range with another device or individual carrying a transmitter.

...NT1210 Lab 4.1 Copper Cabling Exercise 4.1.1 Why are standards so important for NICs, connectors, and media? Use your textbook and Internet research to justify your answer. Simple because Stability, Consistency, Minimization of packet errors. 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. Because the voltage (or current) used to transmit data needs only be high enough for the receiver to detect it. Making the voltage (much) higher would make the receiver electronics more difficult. Exercise 4.1.3 What are some applications of shielded copper cable? Why is the more expensive shielded cable used in these situations? Use your textbook or Internet research to support your answer. The extra covering in shielded twisted pair wiring protects the transmission line from electromagnetic interference leaking into or out of the cable. STP cabling often is used in Ethernet networks, especially fast data rate Ethernets. Exercise 4.1.4 Complete the entries in Table 4-1. Use your textbook and Internet research to compose your answer.

...NT1210 Lab 5.3 Finding Network Settings Exercise 5.3.1 For this exercise, you will release your IP address using ipconfig. This is a beneficial tool for troubleshooting your own local network and correcting any problems with the assignment of IP addresses. This exercise requires that you have DHCP in use for assigning IP addresses, which is a typical default setting. To begin, you should type the command ipconfig at the command-line interface and press Enter. Record the information it presents for the IP address and default gateway; you can ignore the rest of the information for now. When you have completed this, type the following command to release the IP address: Ipconfig /release To renew your lease on the IP address for your network card or adapter, you will use the following command: Ipconfig /renew This will create a new lease on an IP address for your network card or adapter. When the command to renew the IP address is complete, you should compare the result to the initial run of ipconfig and compare the results. Are the entries the same for the IP address and for the default gateway. Exercise 5.3.2 You can use the ping command on your local machine. This does not send traffic out onto the network, but it is an effective means of making sure that your network adapter is functional.

What are the distinct differences between them? Applications, Transport, Network, Network Interface this the TCP/IP model. A huge difference is that TCP/IP model uses 4 major layers instead of 7 layers to OSI model. OSI Model is Applications, Presentation, Session, Transport, Network, Data Link and Physical composed to 7 layers. OSI was developed as theoretical model, while TCP/IP was more practical model. Exercise 3.3.2 Identify the layer in which each protocol resides according to the TCP/IP model Transport layers: The Internet Protocol (IP), Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). These core protocols support many other protocols, to perform a variety of functions at each of the TCP/IP model layers. Still others enable user applications to function. Exercise 3.3.3 The most common protocols used from this suite are IP, TCP, and UDP. Briefly describe the purpose and function of each of these. Use your textbook and Internet research to support your answer. TCP (Transmission Control Protocol) Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data.

...NT1210 Lab 4.2: Fiber-optic Cables Exercise 4.2.1 The light in an SMF cable travels down the center of the fiber parallel to the direction of the fiber in a single path. Can this type of cable be used to transmit and receive bits simultaneously, or does it require one fiber for transmitting and one for receiving? Justify your answer using your textbook and Internet research. No it cannot transmit and simultaneously receive bits with a single cable. A second cable would be needed for sending bits back. In this case you would need two cables one send bits and second cable receiving bits. Exercise 4.2.2 What characteristics of fiber-optic cables allow them to be used over longer distances with less risk than copper cable? The core in single-mode fiber is only approximately 10 times larger than the wavelength of the light it is carrying. This leaves very little room for the light to bounce around. As a result the data carrying light pulses in single-mode fiber are essentially transmitted in a straight line through the core. Electromagnetic immunity including non-conductivity, Security considerations, decreased attenuation and increased transmission distance, Increased bandwidth potential, Small diameter and weight Long term economics Exercise 4.2.3 MMF distances can still far exceed copper cable, but MMF cannot match the distance available from the more expensive SMF. What is the reason for the distance limitation with the use of MMF? Multimode cables are less......

Microsoft and Vmware Comparison

...NT1210: INTRO TO NETWORKING WEEK 5 ESSAY Microsoft and VMware Comparison Tyler Reed In today’s world of cloud storage, cloud computing, and virtualization; I think it is important to understand what virtualization is before comparing the different options. Virtualization first started in the 1960’s as a way to logically divide the system resources provided by mainframe computers between different applications. It is very important to remember that computer strength and hardware performance wasn’t as strong or efficient when this method was introduced. While today’s smartphones are inherently stronger than the best computer during that time, the base problem still exists. Mainly because of the amount of resources needed to run multiple applications, allow server access to potentially thousands of computers and devices accessing the same computer or hardware. Since the concept’s inception the meaning has broadened into hardware virtualization, mobile virtualization, and desktop virtualization. Virtualization has helped organizations reduce cost and increase efficiency in the data center. New virtualization products allow for different benefits and challenges and must be carefully considered for businesses to realize the long term benefits, such as increasing user productivity and decreasing IT costs. Microsoft has the largest range of desktop virtualization and management products that can be integrated into a flexible solution for many different scenarios.......
