5.1.1
The IEEE 802.1standard concerns with the standards and recommendations in the of architecture and internetworking of local area networks (LANs) and metropolitan area networks (MANs), security, network management, and protocol issues above the Data Link Layer.
5.1.2
The original 802.3 standard that defined PoE is IEEE 802.3af. The standard was enhanced in 2009 and give the new standard name 802.3af PoE+.
5.1.3
Standard | Cabling | Maximum Length |
10BASE5 | Coaxial (thicknet) | 500m |
10BASE2 | Coaxial(thinnet) | 200m |
10BASE-T | UTP (cat3, 5, 5e, 6) | 100-150m |
100BASE-FX | Fiber optic | 400m |
100BASE-T | UTP or optical fiber | 100m |
100BASE-T4 | UTP (cat3, 5, 5e, 6) | 100m |
100BASE-TX | UTP (cat3, 5, 5e, 6) | 100m |

1000BASE-SX | MM Fiber optic | 220m or 550m (depends upon fiber thickness) |
1000BASE-ZX | SM fiber optic | 100km |
1000BASE-T | UTP (Cat5) | 100m |

5.1.4
The numeric prefix before BASE in the Ethernet standards defines the transmission speed. The postfix –T implies twisted pair.

5.2.1
A MAC address must be unique for every NIC produced because switches forward frames based on their destination MAC address and if more than one NIC in the same LAN were to have the same MAC address (including the last 24 bits in the MAC address) then the switches would be confused as to which NIC would get the frame.

The Smart Home

...Ruth Rininger Professor Alma Scott CINT 106 7 May 2013 The Smart Home On your morning commute, have you ever thought, did I turn the hallway light off? What about the coffee maker? Did I set the security alarm? With a smart home, you wouldn’t worry about these things at all; you would just pull out your smart phone or your work computer, visit the Internet, and control your house. Have a hard day at work? When you walk in the door, you can have your favorite music playing and the lights dimmed. Worried about what your teenager is doing to your house while you’re away? Just watch him or her online from wherever you are. Do thoughts of the smart home bring to mind images of the Jetsons? The technology is not quite to that level, but give it time. What is a smart house? According to Craven, “a smart house is a house that has a highly advanced automatic systems for lighting, temperature control, multi-media, security, window and door operations, and many other functions” (1). Practically anything in your home can be networked, including drapes and shades, gates, garage doors, door locks, doorbells, lights, dishwasher, refrigerator, heaters, alarm clocks, washer/dryer, microwave, coffeemaker, hot water system, air conditioners, central vacuum system, water controls, pool cover, fireplaces, toys, e-books, lawnmower, cars and other vehicles, piano, weather station, and furniture. Also able to be networked are audio and video devices, such as receivers, amplifiers,......

Be Smart

...English! This can be a challenging and fun exercise for the mind. (Note, try to be patient and positive when studying a language as it may take time to reach the level you desire.) Always ask questions. Asking questions and questioning everything around us constantly is what makes us smarter. There's nothing wrong with not knowing the whys or the hows! Everybody has something that they don't know. But by developing a healthy habit about asking when you don't know something, you'll find yourself getting smarter and smarter. Always learn. There are many sources of information out there. For example: books, documentaries, and the internet. School is just one source of information. If you have straight A's, that doesn't mean that you are smart. Exercising an open mind will make you more intelligent and constantly learning will help you get there....

...Intelligence I have this theory about intelligence. It's an over-simplified theory but here it is... There are three basic levels of intelligence. The first level consists of people who are not smart enough to know anything about the complexities of the universe and the deep suffering humanity has endured since its beginning. These people, unaware of the dark or disappointing aspects of existence, take blissful pleasure in small, insignificant things like a sunny day or a blueberry waffle. They spend their days with dumb looking grins on their faces, talking about unimportant, simple pleasures. The second level of intelligence is made up of people who are smart enough to have a notable understanding of those complexities of the universe and that deep suffering that humanity has endured. With their grasp on the bleakness of existence, they see no emotion in a sunny day, knowing full well that emotions are nothing more than chemical reactions in our brains, triggered by our environment to help dictate our actions in ways that might benefit our species. They fail to see the point in that blueberry waffle, knowing that at any given time, uncounted people around the world are dying of hunger caused by corruption. People within the third level of intelligence are also aware of these detailed and dreary points of our world. They understand the moral failure that so much of our planet endures. They know about the distant, permanently undiscovered details of the universe......

Smart Grid

...Smart Grid: Focus Areas Smart Grid The current electric grid was conceived more than 100 years ago when electricity needs were simple. Power generation was localized and built around communities. Most homes had only small energy demands such as few light-bulbs and a radio. The grid was designed for utilities to deliver electricity to consumer's home and then bill them once a month which is a one-way communication which is illustrated in figure 1; Before smart Grid. Figure 1: Pre and Post Smart Grid communication This limited one-way interaction makes it difficult for the grid to respond to the ever changing and rising energy demands of the 21st century. The smart grid introduces the two-way dialogue where electricity and information can be exchanged between utility and its customers shown in figure 1; After smart grid . Its a developing network of communications, controls, computers and automation, and new technology and tools working together to make the grid more efficient, more reliable, more secure, and more greener. The smart grid enables newer technologies to be integrated such as wind and solar energy production and plug-in vehicle charging. With our participation as informed consumers, the smart grid will replace the old infrastructure of today's grid. And utilities can better communicate with us to help manage our electricity needs.

Smart Card

...Smart Cards for Future Healthcare Systems Secure, efficient, reliable Card-based e-health networks: cutting costs and improving care All around the world, news­ paper headlines warn about the exploding costs of health­ care. Advanced medicines and technology are boosting life expectancy. As a result, people can now look forward to living past the age of 80 – twice as long as 100 years ago. This trend, however, has the side effect of driving up healthcare costs. As people get older, they need more frequent and more expensive care, causing the price of insurance to skyrocket. Clearly, something needs to be done to contain these costs. A number of countries have implemented conventional measures aimed at saving money. One of the most basic measures is the introduction of card­based e­health net­ works, which can help reduce costs remarkably. Card for physicians and phar­ macists, and a Card Application Management System (CAMS). Patient Data Card The Patient Data Card is a PIN­protected smart card incor­ porating a microprocessor and protected by cryptographic functions. It contains adminis­ trative insurance information and entitles patients to seek medical treatment. In turn, the patients give their doctors access to their personal medical data, which is stored either on the card or in the e­health network. The card can also hold information such as elec­ tronic prescriptions. How to cut healthcare costs 1. Reduce fraud 2. Streamline administration 3. Improve communication 4...

Book Smart or Street Smart

...Stephanie Collado Professor Gronsky ENG 103 Book smart or Street smart From when we were little kids to grown adults it is put in our heads that education is the most important experience to have in our life. It lets you be able to achieve any dreams and goals that you want. On the other hand there are people who are successful without school education and succeeded in receiving their careers with talent and hard work. This is what people call street smarts, things that people learn from their own personal experiences or what they see markets more in the social world. People argue that if you don’t go to college and get a degree you won’t have success or wealth, and some people argue that not going to college gives you more freedom and is less time consuming. Having street smarts helps people understand each other better on a more personal level then being judged on how smart or dumb the person is based on a degree. College isn’t accessible to everyone; some people have to be really smart or born into a wealthy family to attend. Having a college education gives people a professional look and the confidence to get a good paying job that will help support their lifestyle. College also lets people express themselves, letting them become comfortable in being social and speaking in front of large groups of people. When going to college some people don’t realize that they are taking out a loans and debts that they’ll have to set an exact plan......

Smart Grid

...critical compo- nents of most efforts to go “green.” Enter the smart grid. A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce costs, and increase reliability and trans- parency. The smart grid enables information to flow back and forth between electric power providers and individual households to allow both consumers and energy companies to make more intelligent decisions regarding energy consumption and production. Information from smart grids would show utilities when to raise prices when demand is high and lower them when demand lessens. Smart grids would also help consumers program high-use electrical appliances like heating and air condition- ing systems to reduce consumption during times of peak usage. If implemented nationwide, proponents believe, smart grids would lead to a 5 to 15 percent decrease in energy consumption. Electricity grids are sized to meet the maximum electricity need, so a drop in peak demand would enable utilities to operate with fewer expensive power plants, thereby lowering costs and pollution. Another advantage of smart grids is their ability to detect sources of power outages more quickly and precisely at the individual household level. With such precise information, utilities will be able to respond to service problems more rapidly and efficiently. Managing the information flowing in these smart grids requires technology: networks and switches for power management; sensor and......

This includes newspapers, magazines, television, internet, film and music. In today’s society that involves technology. Technology in the modern age has connected all forms of media into a new machine. In a fast moving and ever changing industry multi-media devices must be created to give access to the masses. These devices have to be state of the art, reliable, flexible and affordable. Electronic company’s such as Samsung, Sony, LG and Phillips Magnavox have found a way converge multiple forms of media. The creation of the SMART TV has connected television with the internet, and in turn created the most accessible form of media convergence. This paper will walk through the history of television and how it’s advances has brought it the ultimate media convergence. The first successful use of a television was demonstrated in 1927. The unit was created by Philo Taylor Farnsworth. Farnsworth created a system that could capture moving images in a form that could be coded into radio waves and then transformed back into a picture on a screen. The images produced were very primitive but television would grow in the years to come. After Farnsworth invention RCA invested $50 million in the development of television. This investment was used to update broadcasting systems for the new content and to create...

Smart Metering

...SMART METERING WHAT IS A SMART METER? A smart meter is usually an electronic device that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing. Smart meters enable two-way communication between the meter and the central system. CloudIndustries.eu provides you several Smart Metering Solutions as per your needs and requirements. Smart meters are an important tool for helping people understand and quantify energy use. They differ from a traditional meter, by providing accurate energy use data in real-time.  Our aim is to make energy consumption more visible and help people to understand how much they are actually using. WHY DO THEY MATTER? Pretty much everything we do. But when it comes to energy, we haven’t really seen the same technology transformations take place. Many of us have our meters hidden away in a cupboard under the stairs. Smart meters will change this, as they come with a smart energy monitor that shows you what you use, as you use it, and gives you new control over your energy consumption, along with the opportunity to save money. And you can say goodbye to estimated bills and meter readings – smart meters automatically send readings back to your supplier. So when you receive your bill, you’ll know you’re only paying for the gas and electricity you’ve used. WILL I NEED TO DO ANYTHING? Once your smart meter is up and running, your meter......
