Building TCP/IP
Networks
This chapter will allow you to explore the common models of networking from the physical media connection to the application that displays the information, including how these layers interact and how they map to real networking devices. The labs in this chapter are designed to reinforce concepts from Chapter 3 of your Introduction to Networking textbook and allow you to explore some of the more important ideas with greater depth. You will explore the different types of network reference models available and analyze how each one applies to real network technology. You will also use packet capturing to look at real network traffic and explore the data link layer of networking. At the end of this chapter, you should be able to
■ Explain the purpose of network reference models ■ Describe the layers of the OSI reference model and explain what each layer provides ■ Describe the layers of the TCP/IP model and relate it to the OSI model and real networking equipment
■ Capture live packet information on a network and explain the data link layer portion of the packets captured
■ Enable network resources such as shared printers and file sharing on your own PC

...NT-1210 Intro to Networking 05/30/2012 CH 10-11 Research Paper Essay In the evolution of smart phones the first use of text messaging did not take place until 1992 in England, and this was from a computer to a cell phone. The first cell phone to cell phone text happened in 1993 in Finland, which during this period was leading the cell phone technology race, and in 2000 was the first to offer mobile news services. In this time period of the early 2g (second generation) and 2.5g networks mobile providers started to pop up everywhere making communications more reliable. In 2001 the 3g network was introduced and with this technology came the ability to send pictures and stream video. Mobile providers started to offer media content such as ringtones, news, weather, jokes, music and videos, which in 2007 reached 31 billion in sales and outpaced computer internet sales. In the business aspect of this technology, all of this is the icing on the cake. The ability to keep in touch with your employees at any time or location is priceless. Gone are the days of the travelling salesperson with only the information that was current when they began their journey. Changes to information or current events can be sent immediately, lost files can be sent, up to date sales figures can be accessed and video conferencing is possible....

...Intro to Networking Lab 3 Jeff Garwood EX. 3.1 Review 1. The MAC Address is sufficient to route traffic locally because it provides the needed information with regards to the equipment location. This is mostly true on level 2 networks. 2. The Open Systems Interconnection was started in two documents in 1978. The International Organization for Standardization (ISO) and the International Telegraph and Telephone Consultative Committee, or CCITT. In 1983 these two documents were combined as the basic reference model for the OSI. It was created so Protocols could allow the entity in one host to interact with a corresponding entity at the same layer in another host. 3. The TCP dates back into the 1960s on the DOD sponsored ARPANET. In 1973 the TCP/IP came to be and consisted of dozens of different protocols. Of these key protocols, two are usually considered the most important. The Internet Protocol (IP) is the primary OSI network layer (layer three) protocol that provides addressing, datagram routing and other functions in an internetwork. EX. 3.2 Review 1. The composition of the physical wiring, and connectors no matter the type are strictly regulated to ensure the electrons within the communications signal can move fast enough to maintain a connection. The addition of network devices such as switches and routers complete the campus style network. 2....

...With this method it not only pertains to networking but to real life as well. Layered architecture is not a new process it has been around for quite some time. A protocol is a set of rules that allows the communications between computers on the network. These rules help regulate the guidelines of speed data transfer and access method. A society based protocol would be like a motorcycle club. For example the network would be the president and the computers would be the other members. The protocol would be the Sgt of Arms as for he would be the one that controls the communication between he members and the president. The four types of different networks are LAN (local area network), WLAN (wireless local area network), WAN (wide area network), and VPN (virtual private network). LAN is your most basic form or network; this is where all the computers belong to the same network and plugged into the same hub. WLAN is your second most basic home network, this is where you are wirelessly connected to the internet in your home and can be connected through multiple devices. WAN is a network...

...Chapter 2 Mind Map Chapter 2 Lab Two Extra Sources Some of the things that I have learned from searching information on chapter two are that there are way more networking systems then I have ever dreamed about. I just thought WAN stood for wide area network and was just another name for the internet. I learned that WAN is everywhere we are and imbedded in our lives. One of the biggest claims of this would be the ATM. I have used it many times but never knew that it was running off of a WAN. I also found out that WAN can be localized as well as worldwide and that it can incorporate the city you live in, the state you live in, and even the United States. Mind Mapping is a brain emulating method for generating and organizing ideas. This was inspired by a great man and his way of doing things, which was Leonardo da Vinci's and his approach to note-taking. Now that is something really cool and another reason we should have been doing something like this a long time ago. Mind mapping is more than just a simple brain storming tool, it is a tool that we can use to organize our lives, organize our jobs and our responsibilities, and it can even be used to organize our day to make us more proficient in our jobs. I am glad that I have been introduced to this tool so early in my career. Bibliography WAN, MAN, LAN, PAN, And SAN: Evolution, Not Revolution | Digital ICs content from Electronic Design. (n.d.)....

...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 requiring re-amplification of the signal. http://www.imakenews.com/drs/e_article001146955.cfm?x=b11,0,w https://people.richland.edu/dkirby/142fibercable.htm Exercise 4.3.2 Rank the three main types of cable (UTP, SMF, and MMF) in a hierarchy of use for connecting network devices based on your completed comparison table....

Why is this inefficient for establishing a connection to the Internet? What was the limitation of the data rates available on this type of Internet connection? First you had to make sure that your call waiting feature was turned off so that there wouldn’t be any interruptions in the service. Because it was like using the telephone, your data rates were charged as long distance telephone calls by the minute. 9.1.2 The term broadband Internet generally refers to higher-speed and constantly available connections to the Internet. The term represents an evolution of Internet connectivity, but it originally referred to the type of media usage. Broadband and baseband are the two types of media usage available. Briefly define these terms and explain the difference between them. Broadband – The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. It also includes several high-speed transmission technologies such as Digital Subscriber Line (DSL) Cable Modem.

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.
