Data enters the system it gets converted into binary computer language. This data is sent through the network and encapsulated into packets. These packets have headers and trailers which indicate the direction of travel. Therefore the packets carry the information to and from destination. In addition this includes a number place in other words it keeps its place in the order it was sent.
The packets travel through routers as in goes through the network. The access network router would be the first router. The packets are not limited to just one router sometimes these packets will travel through multiple routers in multiple topologies. This can include Regional Networks, Long-Haul Networks, and Ocean Networks. The network and each router will determine which direction of travel is best path for the packet. As things change within the network something are slower than others it learns from it and makes changes for better performance. With this method the packets will more than likely arrive out of order. Depending if you use TCP or UDP, you will get an acknowledgement of the receipt of each packet to the sending system. The sending system will resend any lost information. When the all the packets get to the destination, they get put back in order based on the header and trailer information. Than the data goes the reverse order of encapsulation to be read at the server or computer. This all happens usually at the milliseconds, in reference to time taken. The server would send information back along similar lines except that the data could take a different route based on the routers routing table at the time of…...

...Unit 6. Assignment 1. AD User/Group Design Scenario Dear Junior Admin, I received your E-mail and in response I recommend that you do the following. Since there is a domain for each department, such as Marketing, accessing one printer is rather easy. To start off you will need to create a group that allows access to the one printer within each department in your company. After creating each group you must then assign it to a domain local group, global group and then to a universal group. Then you will need to add it to the marketing domain local group. For HR, you will need to take all of the users within the forest and add them to a global then universal group. Proceed to take the universal group and add it to the domain local group within their domain. These users will then have access to whatever is in that universal group, therefore you must make sure that you assign the printer for them to print vacation requests to the HR department. You must take a slightly different approach for R&D. To allow access to only the server, you must first create a domain local group that has some administrative rights. Add them to a customized admins group that you have control of. You can assign these rights and permissions as you create and assign them. Remember to limit their access to their local machines only. You can do all of this through the desktop local user account settings. You may also take a different route if you choose to. This is one of the approaches you may......

...The world is connected more than ever through the use of the internet. From paying bills to shopping or enjoying leisure time on the web; taking advantage of the internet has become second nature to society. Focusing in on one specific type of networking entertainment, online gaming has become a major league sport in its own right. Online gaming allows people from all around the world to connect together to team up or fight against one another. Behind the scenes is where the real magic happens. Between the gamers sits countless devices and hardware not to mention miles and miles of land. Using Call of Duty as an example, each gamer has a copy of the map being played on installed onto their local computer. Every time the gamer moves the direction of their character, their data is sent from their machine to their router, and then out past the demarc point. On the other side of the demarc is where the service provider picks up the data and moves the data from local network to the central office (better known as the local exchange). The central office then sends the data over the MAN (metro area network) or WAN (wide area network) to continue the data to game server. If the data hasn’t reached the server yet (for example the gamer lives in Michigan and the server is in California) the data will be passed over the core (also known as long-haul) network which connects MANs and WANs of different geographies together. On the off chance the Michigan gamer decided...

...Michael Campbell 10/15/2014 NT1310 Unit 5 Lab1 New Building – Wired and Wireless The advancements in technology have made it necessary to rely on a combination of solutions to keep the cost so there is not any sacrificing security. For the most part, the basis of the network will be a wired solution. A wired solution will keep the security high, so a hacker would have to be physically attached to the network to gain full access. Running a wired network is more cost effective because wireless technology is still new enough so the cost is higher. By running new wired networks, longevity can be built into it by planning ahead. Racks, patch cabling, and wired routers are less difficult to troubleshoot. A wireless solution is can be very attractive due to the fact that there are relatively few cables, but they are more susceptible to security issues and cost is higher than wired networks. This network is less of a physical set up and more of a logical network, due in part to assigning and managing all of the IP addresses. Wireless routers, wireless access points, and Wi-Fi network cards have their limitations, however they can be utilized in areas (such as an internet café) where security is not as important. The tools for both types of installs are mostly the same, with a few differences depending upon the cable types being used; the testing tools change a bit when going after the range of the wireless network. There are many apps for your smartphone that allow you to......

...Cell Phones – Cellphones use both voice and data communication. To give an example: a person talking on a cellphone will use “voice” communication. On the other side, “Data” technology is also used on smartphones which allow them to search the internet and download different files. Landlines – Landlines usually and more than common use voice communication. Though newer landlines have the option to use what’s called a NCID (Network Caller ID) which uses data sent over a TCP connection. SMS/Text Messaging – SMS or text messages can be used in a variety of ways. Examples include: cellphones and internet texting. SMS does not use any kind of voice technology and therefore is sent over data networks. Fax Machines – Fax machines have analog modems. This type of modem technology uses the voice network. When the receiving end gets a fax connection it listens for a digital connection that has been converted from an analog signal using a voice network. Pagers – Pagers were primarily a data network. They worked by sending numerical short messages, something that may have been a bit similar to texting but with numbers. Since the introduction of data pagers, voice pagers have also been brought into the picture. These types of pagers use the” voice” network. VOIP Phones – VOIP (Voice over Internet Protocol) is a technology that can transmit audio messages over the internet. VOIP is transferred over an internet protocol it thereby uses data networks.

The older cell phones used voice only, they didn’t have the capability of a data network. You can also stream audio and video using your cellular network. Landline Phones: Landline phones are voice only. There is no way to use data through a landline phone. It can be used for internet but that is through a dial up connection. Landlines work within a network of central hubs that started out with a human operator connecting you to another person. SMS/Text messaging: Text messaging is a data service that allows users to send messages back and forth between their devices. You can also send pictures through text messages. Fax Machines: A fax is sent immediately gets digitized and packaged in secure TCP packets and sent to natural data Inc. Fax machines use an analog data signal.

Assignment Requirements Respond to the following scenario with design considerations and recommendations: You are an IT Administrator for a newly founded company and have been tasked with designing an IP addressing scheme and a plan for allocation and management of IP addresses. The company will currently have a single, physical location with approximately 145 hosts (computers, printers, etc.). IT plans should accommodate 50% growth within the next two years. At a minimum, address these specific questions, in addition to any other concerns/considerations: 1. What subnet range/s should be used? 2. Should IP addresses be dynamically or statically assigned? 3. Should one or more network/subnets be used? 4. If DHCP is used, should a router, firewall or Windows Server be utilized and why? Respond in detail, justifying your recommendations. In your response, consider future growth and design considerations. Submission Requirements 1-2 pages, Microsoft Word, double-spaced, 12 pt. font In response to your question I would use a classless addressing and start at 172.16.0.0 for your network address with a subnet mask of 255.255.255.0.

...Unit 1 Summary: Chapters 1,2,3,4 Chapter 1 – The TCP/IP and OSI Networking Models: * A network model sometimes also called either a networking architecture or networking blueprint refers to a comprehensive set of documents used to describe the functions of a network as a whole * The international organization for standardization (ISO) took on the task to create such a model, starting as early as the late 1970’s beginning work on what would become known as the open systems interconnection (OSI) networking model. * IP defines addresses for several important reasons. First each device that uses TCP/IP needs a unique address so that it can be identified on the network and IP also figures out how to group addresses together. * The term IP host refers to any device, regardless of size or power that has an IP address and connects to any TCP/IP network * The Current OSI Model: 1. Application 2. Presentation 3. Session 4. Transport 5. Network 6. Data Link 7. Physical Chapter 2 – LAN Fundamentals: * File Sharing: Each computer can be configured to share all or parts of its file system so that the other computers can read, or possibly read and write, the files on another computer. * File Transfers: A computer could install a file transfer server, thereby allowing other computers to send and receive files to and from that computer. * The term collision domain defines the set of devices whose frames could collide *......
