...FUTURE STATEMENT Solar Technology Although not widely used, I believe the future of Solar energy technology products such as Solar panels is bright. Solar technology is one of the green energy sectors that is making a lot of difference here at home and around world. For instance, the use of solar panels in homes is very popular in most third world countries since energy cost is expensive. The cost and accessibility of this technology is much easier than here in the U.S. For instance in Africa, the use of solar panels in homes is very common. Cheap imports from China have made it affordable for most home owners. The panels are easily available and are installed by contractors without any red-tape if the person can afford it. Although, most of these countries are poor and lacks basic infrastructures, solar energy has given them the opportunity to be less dependent on fuel imports and benefit the technological advantages of a clean energy economy. On the other hand, here in the U.S. the use of solar panels in homes is not as popular as other countries. The average American homeowner doesn’t know where to buy these panels or how to get them installed. Home buyers have the perception that solar panels are not affordable so they are reluctant to consider them as an option when they build or buy a new house. Furthermore, the burden of getting licensing and permit scares off a lot of homeowners who otherwise would have benefited from this green energy technology. Regardless, I am...

...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 measure...

...Application is a term used to describe the different types of cable i.e. cat5, cat5e, and so on and the different shielding or fire rating Unshielded Twisted-Pair is copper wire that is used in a twisted pair. Which is two conductors of a single circuit that are twisted together to prevent crosstalk UTP typically have only one outer covering or jacket for one or more of the twisted pairs. Shielded Twisted-Pair is copper wire that is almost the same but also with the outer covering each twisted pair is also shielded separately and then shielded again before the outer jacket Fiber-Optic Cable bandwidth is dramatically higher than with copper speeds and it uses a strand of glass or plastic to transmit data using light pulses transmission distances are much further away it is not susceptible to outside EMI or crosstalk interference. It is more secure than copper wire it very hard to tap in to unlike copper wire. Dark Fiber is just a term used for unused or unneeded strands of installed fiber because you always want to install more than you need cause networks always grow.

...Ryan Heath NT1310 12/14/14 Unit 1 Assignment 1 Cell Phones: Cell phones use both data and voice networks. Although most people text now a days and rarely do people call each other. 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. Pager: A way to notify individuals of incoming calls by tone, it uses a data signal. This was the start of the text message area. People could use a series of numbers to send messages. VOIP: Voice over IP is a phone that uses digital technology to make phone calls on the internet rather than through phone lines. A VOIP phone allows us to bypass the phone companies completely, it uses data networks. Skype/Facetime: To use these services you have to have a data network in order to get on the internet to use...

...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...

...Network Topology Star Topology has its own cable that connects to a central hub or switch, multipoint repeater, or even a Multistation Access Unit. Data passes through the hub to reach other devices on the network. A hub, switch, or computer acts as a router to transmit messages this is in its simplest form. Star reduces the chance of failure in the network by connecting all of the systems to a central node. Star is the most common networks because of the ease of configuring and troubleshooting it. If a wire goes bad only one node will go down which prevents a huge impact on productivity. However, because a star involves a central hub or switch as well as a lot more cabling it cost more to implement. Bus topologies computers are connected to a single cable or trunk or backbone by a transceiver either directly or by using a short drop cable. All ends of the cable must be terminated, that is plugged into a device such as a computer or terminator. The number of computer affect the performance since only one computer at a time can send data the more computers you have on the network the more computers there will be waiting to send data. If there is a break in the line all computers will fail. Bus is inexpensive and very easy to install. They are limited in security and number of devices that can be on the network. Bus can only transmit slowly at 10 \Mb/s. Ring topology network computers are connected by a single loop of cable, the data signals travel around the loop in one...

...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 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...

...Introduction One of the most important items about gaming is there are winners and losers (in a fun and entertaining way), which influences and entices players all over the world. All of the variables involved with the networks that provide gaming platforms are so dynamic and diverse. From games that are purely for fun or learning there will be a huge market for deploying bigger networks. This is one reason networks growth should grow exponentially. Below is what I have identified as a gaming or Local Exchange network. “Retrieved from, http://www.psu.com/a018031/” 12/17/2013 Posted January 17th, 2013 at 19:30 EDT by Timothy Nunes “Retrieved from, http://www.hcl-axon.com/Our_Products/gamedge/” 12/17/2013 “Retrieved from, http://compnetworking.about.com/od/homenetworking/ig/Home-Network-Diagrams/Hybrid-Network-Diagram.htm” 12/17/13 By Bradley Mitchell References • Home Wi-Fi Security Checklist Cited in the "Handbook of Electronic Security and Digital Forensics" and other titles! • Fixing Common Internet Connection Problems There's nothing more frustrating than a broken Internet connection.

...Fixed line vs Cellular Cell phones have limited coverage area, unless in a big city with a lot cell phone towers, but there are other ways the signals can be blocked as well. Which makes a cell phone less dependable. The batteries in a cell phone need to stay charged to make or receive calls, and as long as it is charged you can use your phone any time even if you are somewhere where there is no power. Cell phone plans are usually cheaper is you are just getting a plan to talk on the phone and not a plan that includes data. A land line always works (unless it a cordless phone and the power goes out). You do not need to charge a land line phone that is connected to the wall, and you do not have to worry about a weak signal. The cost is more especially if you need to make long distance calls because that is not included in a normal plan. Voice vs Data Cell phones use both, you can use the voice and data at the same time because they no longer use the same antenna. Landlines phones use both, the key tones use data because the tones transfer as data, and you talking is using the voice SMS/text uses data, and is transferred as a message with characters over the data network Fax uses the data, when a fax is sent it gets immediately digitized and packaged in secure TCP packets and sent to natural data inc and then secure networks operation center for final delivery. Pagers use data, they receive a number via a small screen from incoming callers VOIP uses the data network...

...Windows 8 is a Microsoft operating system that is designed for home users as well as for business purpose. Its development started even before its predecessor’s release Windows 7 in 2009.Windows 8 is a system that is particularly orientated to touchscreen hardware. There are some important changes and additives that make it look and differently than the users are used to. For example, the Start menu is completely substituted by a Start screen that can be taken away from the desktop easily by touch screen pen and also by just a normal mouse or keyboard key combination. It contains all the important applications also the ones that are active at the moment. All the icons in the old version of the operating system are changed into tiles that can be juggled with. It can stay constantly on the screen or can be hidden.And now the most important that users expect to hear – when will it be available for the public and for what price? The official release date is the 26th of October, 2012. It was preceded by three pre-release editions while still being developed and tested for the period of the 13th of September 2011 until 31st of May 2012. There will be four editions issued on the market – two general editions just for conventional use, one Pro release of Windows most ardent devotees and Enterprise edition which is for business purposes. ² Windows 8 is the current release of the Windows operating system, produced by Microsoft for use on personal computers, including home and business...
