A Networking Academy delivers web-based content, online assessment, student performance tracking, and hands-on labs to prepare students for industry-standard certifications. The CCNA curriculum includes four courses oriented around the topics on the Cisco Certified Network Associate (CCNA) certification. LAN Switching and Wireless, CCNA Exploration Labs and Study Guide is a supplement to your classroom and laboratory experience with the Cisco Networking Academy. In order to be successful on the exam and achieve your CCNA certification, you should do everything in your power to arm yourself with a variety of tools and training materials to support your learning efforts. This Labs and Study Guide is just such a collection of tools. Used to its fullest extent, it will help you gain the knowledge and practice the skills associated with the content area of the CCNA Exploration LAN Switching and Wireless course. Specifically, this book will help you work on these main areas:  ¦ LAN design principles and concepts  ¦ Ethernet operation with switches  ¦ Basic switch configuration and security  ¦ VLAN concepts and configuration  ¦ VTP concepts and configuration  ¦ STP, RSTP, and rapid PVST+ concepts and configuration  ¦ Inter-VLAN routing concepts and configuration  ¦ LAN wireless concepts and security issues LAN wireless configuration using Linksys WRT300N routers  ¦ Troubleshooting LAN switching and wireless configurations Labs and Study Guides similar to this one are also available for the other three courses: Network Fundamentals, CCNA Exploration Labs and Study Guide, Routing Protocols and Concepts, CCNA Exploration Labs and Study Guide, and Accessing the WAN, CCNA Exploration Labs and Study Guid e. Audience for This Book This book’s main audience is anyone taking the CCNA Exploration LAN Switching and Wireless course of the Cisco Networking Academy curriculum. Many Academies use this book as a required tool in the course, while other Academies recommend the Labs and Study Guides as an additional source of study and practice materials. The secondary audiences for this book include people taking CCNA-related classes from professional training organizations. This book can also be used for college- and university-level networking courses, as well as anyone wanting to gain a detailed understanding of basic switching and wireless technologies. 00_2028_fm. qxp xviii 4/3/08 5:08 PM Page xviii LAN Switching and Wireless, CCNA Exploration Labs and Study Guide Goals and Methods The most important goal of this book is to help you pass the CCNA exam (640-802). Passing this foundation exam means that you not only have the required knowledge of the technologies covered by the exam, but that you can plan, design, implement, operate, and troubleshoot these technologies. In other words, these exams are rigorously application based. You can view the exam topics any time at http://www. cisco. com/go/certifications. The topics are divided into eight categories:  ¦ Describe how a network works  ¦ Configure, verify, and troubleshoot a switch with VLANs and inter-switch communications  ¦ Implement an IP addressing scheme and IP services to meet network requirements in a medium-sized enterprise branch office network  ¦ Configure, verify, and troubleshoot basic router operation and routing on Cisco devices  ¦ Explain and select the appropriate administrative tasks required for a WLAN  ¦ Identify security threats to a network and describe general methods to mitigate those threats  ¦ Implement, verify, and troubleshoot NAT and ACLs in a medium-sized enterprise branch office network  ¦ Implement and verify WAN links The LAN Switching and Wireless course focuses on the second, fifth, and sixth bullets. The Study Guide portion of each chapter offers exercises that help you learn the LAN switching and wireless concepts as well as the configurations crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes some or all of the following types of exercises:  ¦  ¦ Skill-building activities and scenarios  ¦ Configuration scenarios  ¦ Concept questions  ¦ Packet Tracer Activity Vocabulary matching and completion Internet research In the configuration chapters, you’ll find many Packet Tracer Activities that work with the Cisco Packet Tracer tool. Packet Tracer allows you to create networks, visualize how packets flow in the network, and use basic testing tools to determine whether the network would work. When you see this icon, you can use Packet Tracer with the listed file to perform a task suggested in this book. The activity files are available in this book’s CD-ROM; Packet Tracer software, however, is available through the Academy Connection website. Ask your instructor for access to Packet Tracer. The Labs and Activities portion of each chapter includes a Command Reference table, all the online Curriculum Labs, and a Packet Tracer Skills Integration Challenge Activity. The Curriculum Labs are divided into three categories:  ¦ Basic: The Basic Labs are procedural in nature and assume you have no experience configuring the technologies that are the topic of the lab.  ¦ Challenge: The Challenge Labs are implementation in nature and assume you have a firm enough grasp on the technologies to â€Å"go it alone. † These labs often only give you a general requirement that you must implement fully without the details of each small step. In other words, you must use the knowledge and skills you gained in the chapter text, activities, and Basic Lab to successfully complete the Challenge Labs. Avoid the temptation to work through 00_2028_fm. qxp 4/3/08 5:08 PM Page xix xix the Challenge Lab by flipping back through the Basic Lab when you are not sure of a command. Do not try to short-circuit your CCNA training. You need a deep understanding CCNA knowledge and skills to ultimately be successful on the CCNA exam.  ¦ Troubleshooting: The Troubleshooting Labs will ask you to fix a broken network. These labs include corrupted scripts you purposefully load onto the routers. Then you use troubleshooting techniques to isolate problems and implement a solution. By the end of the lab, you should have a functional network with full end-to-end connectivity. Packet Tracer Companion Most of the hands-on labs include Packet Tracer Companion Activities where you can use Packet Tracer to complete a simulation of the lab. Packet Tracer Challenge Each chapter also includes a culminating activity called the Packet Tracer Skills Integration Challenge. These activities require you to pull together several skills learned from the chapter— and from previous chapters and courses—to successfully complete one comprehensive exercise. A Word About Packet Tracer Packet Tracer is a self-paced, visual, interactive teaching and learning tool developed by Cisco. Lab activities are an important part of networking education. However, lab equipment can be a scarce resource. Packet Tracer provides a visual simulation of equipment and network processes to offset the challenge of limited equipment. Students can spend as much time as they like completing standard lab exercises through Packet Tracer, and have the option to work from home. Although Packet Tracer is not a substitute for real equipment, it allows students to practice using a command-line interface. This â€Å"e-doing† capability is a fundamental component of learning how to configure routers and switches from the command line. Packet Tracer v4. x is available only to Cisco Networking Academies through the Academy Connection website. How This Book Is Organized Because the content of LAN Switching and Wireless, CCNA Exploration Companion Guide and the online curriculum is sequential, you should work through this Labs and Study Guide in order beginning with Chapter 1. The book covers the major topic headings in the same sequence as the online curriculum for the CCNA Exploration LAN Switching and Wireless course. This book has seven chapters, with the same numbers and names as the online course chapters. If necessary, a chapter uses a single topology for the exercises in the Study Guide portion. The single topology per chapter allows for better continuity and easier understanding of switching commands, operations, and outputs. However, the topology is different from the one used in the online curriculum and the Companion Guide. A different topology affords you the opportunity to practice your knowledge and skills without just simply recording the information you find in the text.  ¦ Chapter 1, â€Å"LAN Design†: The exercises in the Study Guide portion focus on LAN design concepts, including vocabulary and the three-layer hierarchical model. The Labs and Activities portion includes a Basic Lab, a Challenge Lab, a Troubleshooting Lab, and a Packet Tracer Skills Integration Challenge activity.  ¦ Chapter 2, â€Å"Basic Switch Concepts and Configuration†: The exercises in the Study Guide portion help you understand basic Ethernet and switching concepts, including building the MAC address table and collision and broadcast domains.

Cable a network that is similar to the one shown in Figure 6-4. You can use any current switch in your lab as long as it has the required interfaces shown in Figure 6-4 and supports 802. 1Q encapsulation. The router you choose must support inter-VLAN routing. The output shown in this lab is based on Cisco 2960 switches and an 1841 router. Other switch or router models may produce different output. Set up console connections to all three switches. Step 2. Clear any existing configurations on the switches. Clear NVRAM, delete the vlan. dat file, and reload the switches. Refer to â€Å"Lab 2-1: Basic Switch Configuration (2. 5. 1)† if necessary for the procedure. After the reload is complete, use the show vlan command to confirm that only default VLANs exist and that all ports are assigned to VLAN 1.

Caught in the Trap free essay sample

Aromas confronted me as I walked in the door. Masalas—or spices—like curry, cumin and cinnamon each contributed. I sat on the edge of my chair—eager like a child on Christmas. I wanted to experience these exotic spices. They were delicious and fiery, yet flavorful. This is not the first time I desired something new. I yearn for knowledge and enrichment. If I hear something I don’t know much about, I look it up. A new technique, style, movie, or crisis—my desire for understanding and knowledge ranges. This time, the Indian food caught me in its trap. I needed not only the flavor—but also the culture. I needed to know more. I needed to understand. This is how I came across Hinduism. I saw the fascinating three-like symbol, the Om, before and I had looked it up. I knew it was Hindi. But my eyes were blind to Indian culture and religion. We will write a custom essay sample on Caught in the Trap or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Enthralled by the beauty of the symbol and the delicious food, I started my research online. Then, I turned to books. One about Hinduism. An India travel guide about customs. And lastly, The Bhagavad Gita—a book essential to Hindus. I started with basics and grew. I learned that the cow is sacred and therefore, beef is not eaten and cows not slaughtered. This was something I found fascinating. Beef is vital in America. A good steak, special and expensive. But in Hinduism, the cow is a symbol of life and honored. I was drawn in by the open-mindedness towards other religions. Hindus believe that religion is the same just named differently. This appealed to me because religion is about loving and accepting and in Hinduism this is true. Hinduism is diverse, allowing its own followers to believe in a variety of things. Religion tends to be strict, and the diversity and variety in Hinduism made it appealing. The travel guide explained Hinduism is a way of life and is reflected in the customs. The Bhagavad Gita gave me insight and helped me learn from the same text that a Hindu would learn from. All this new information made me think in ways I hadn’t before, pose questions and challenge my beliefs. Did I still believe the religious foundation built around me? I wasn’t sure. â€Å"Aren’t you a Hindu or something?† asked my brother. I knew this question was coming, but I still didn’t have an answer. â€Å"I’m not sure.† Before claiming it, I want to fully understand. And I am still working towards that. I may adapt to this religion, I may not. But it doesn’t matter. This search is about understanding and delving into the intriguing unknown. The Indian food caught me. Forever I will recall my first meal at Tandoori Nights a year ago and what stemmed from it. What will catch me next?

Innovating Treatment of Addictive Behaviors free essay sample

Affinity to something is a normal human experience. Having favorites can be considered as a natural phenomenon. When the inclination on a particular something become excessive and has gone out of proportion, it is deemed as an addiction. â€Å"Addiction† is one of the most important and useful concepts in the field of behavioral and clinical psychology. A single definition of addiction cannot be considered as accurate and precise and consider other definition as incorrect. This is because the term addiction is an abstruse word, and definition may vary in different social groups due to its relative aspect, in which descriptions are based solely on opinions. It has no definite boundaries and sets the premise of its definition (West Hardy, 2006). The concept of addiction continually changes throughout time. Nowadays, it was linked to a kind of syndrome impairing the control system of behavior, as losing control over behavior may have noxious effects. We will write a custom essay sample on Innovating Treatment of Addictive Behaviors or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The afflicted control system leads to feelings of extreme urge to do a certain activity or takes great priority in a persons life. A person with addictive behavior experience lacks the ability to maintain abstinence (West Hardy, 2006). Addictive behaviors are one of the major causes of detrimental health problems in the medicine field. These behaviors are also the reason behind unreasonable spending of a great sum of money in health care, rehabilitation, legal, and educational aspect (Prochaska, 2004). Addictive behaviors are a major dilemma which encompasses different social and economic aspect of an individual. Developing an addictive behavior could be destructive and may hinder a person’s social and occupational well-being. The documented treatment for addictive behavior shows low success rates and numerous frustrations. Some of the frequent encountered problems are the inability to identify borderline patients suffering from addictive behavior and the unsatisfactory management and application of appropriate treatment (Nagel, 1989). Overeating, compulsive sexual behavior, and alcoholism are documented addictive behaviors which are discussed separately. The separate documentation for the addictive behavior manifested by these disorders largely contributes to the confusion on the field. There are few attempts wherein specialists try to integrate the different objects of addiction and try to formulate various theories that explain the psychological and behavioral phenomenon. However, these attempts failed to establish a concrete body of knowledge and literature encompassing the various aspects of addictive behavior (Nagel, 1989). It is predicted that efficient treatment on addictive behavior could be developed through the integration of the conventional treatment practices and research paradigms with the contemporary treatment practices. These practices include comprehensive and innovative paradigms (Prochaska, 2004). Prochaska (2004) presented different kinds of approaches that could be used in treating persons with addictive behavior. One of these is the patient and population paradigm. Psychotherapists who are advocates of this approach focus their attention on the statistical data on the efficacy of a certain treatment on the individual patient. They often neglect the percentage of the total population participating on the treatment process. This paradigm is concerned on the impact of the treatment which is calculated as efficacy multiplied by the percentage of the participants. The paradigm is trying to explain that the higher efficacy of a particular treatment does not connote greater impact (Prochaska, 2004). Another approach of treating addictive behaviors is the passive-reactive and proactive paradigms. In the past, therapists utilized the passive-reactive approach. This approach was employed for patients suffering from intense pain, illness, and distress. However, there was the undeniable presence of cases of chronic behaviors and most patients were not suffering pain and ailment. Therefore, they needed an approach that best fit their situation which was the proactive approach (Prochaska, 2004).

The Common Life

The Common Life After reading "The Common Life," and "The Uses of Sidewalks," it is easy to see that the main idea in both essays is security. The question that arises from reading the two essays is: What method is best to provide security in a community? In both essays, though used in different ways; the community is used as a means for security. The types of security provided by both essays are very natural. Though the police are preferred by most people as means of protection, the community looking out for each other is done rather naturally. Thoroughly analyzing both essays can show which security procedure is more efficient compared to the actual police department.Scott Russell Sanders, the author of "The Common Life," has very interesting ideas when it comes to adding better security to the community. Sanders wanted to take the more natural approach in obtaining security. With most people, having a gun, security throughout the home and the police department seem like natural approaches towards security.Sanders Preserve - Glenville, New YorkSanders does not think this is the way to achieve better security. His approach is to get to know the people in the community better. By doing this, as the individual gets to know the people in their neighborhood better, they start to look out for them and make sure they are o.k., without knowing they are doing it. This reflects more of a side-effect rather than the actual intention. It seems as though Sanders analyzed this idea in motion and noticed it was a building block for security. Sanders thought up this idea in hopes that it would spread from community to community, in order to increase security awareness. This was a safe environment could be established.The ideas of Scott Russell Sanders are very interesting yet his ideas have...

Read and Understand Measurements in House Plans

Read and Understand Measurements in House Plans Its easy to purchase house plans from a website or house plan catalog, but they hardly ever come with directions for reading floor plans. What are you buying? Will the completed house measure up to your expectations? The following hints come from an architect who designs luxury house plans and custom homes. He wants you to know about measuring. - ed. Key Facts About Measuring area: measured in square feet (or square meters), the rectangular length times the width; the area of a triangle is one-half the base times the heightvolume: the length times the width times the heightarea of a composite: for an irregularly shaped room, divide the room into regular shapes (rectangles and triangles) and sum the areasgross area: measured from the exterior wall foundation, so the area includes wall thicknessnet area: measured from interior walls; area of the living spacearchitect scale: a three-sided measuring device with six measuring edges (described as prism-shaped), similar to a ruler, but used to interpret the true size of a line drawn to scale on a floor plan or blueprint Size Up Your House Plan When you compare house plans, one of the more important characteristics you’ll consider is the area of the floor plan - the size of the plan - measured in square feet or square meters. Heres a little secret. Square feet and square meters are not measured the same on every house plan. Any two house plans that appear to be of equal area may not really be. Does this make much difference when you’re choosing a plan? You bet it does! On a 3,000 square foot plan, a difference of only 10 percent might unexpectedly cost you tens of thousands of dollars. Question the Measurements Builders, architects, real estate professionals, bankers, auditors, and appraisers often report room sizes differently to better suit their particular needs. House plan services also vary in their area-calculation protocols. In order to compare floor plan areas accurately, you’ve got to be sure that the areas are counted the same. Generally, builders and real estate professionals want to show that a house is as big as possible. Their goal is to quote a lower cost per square foot or square meter so that the house will appear more valuable. In contrast, appraisers, assessors, and county auditors usually measure the perimeter of the house - a typically very rough way to calculate area - and call it a day. Architects break the size down into components: first floor, second floor, porches, finished lower level, etc. To arrive at an apples-to-apples comparison of house areas you’ve got to know what’s included in the totals. Does the area include only heated and cooled spaces? Does it include everything under roof? Even garages? What about closets? Or do the measurements include only living space? Ask How Rooms Are Measured But even when you’ve discovered exactly what spaces are included in the area calculation youll need to know how volume is counted, and whether the total reflects the net or the gross square footage (or square meters). Gross area is the total of everything within the outer edge of the perimeter of the house. Net area is that same total - less the thicknesses of walls. In other words, net square footage is the part of the floor that you can walk on. Gross includes the parts you can’t walk on. The difference between net and gross can be as much as 10 percent - depending on the type of floor plan design. A traditional plan (with more distinct rooms and therefore more walls) might have 10 percent net-to-gross ratio, while a contemporary plan may have only six or seven percent. Likewise, larger homes tend to have more walls - because larger homes generally have more rooms, rather than simply larger rooms. Youll probably never see the volume of a house plan listed on a house plan website, but the number representing the area of a floor plan often depends on how the volume is counted. Typically, the upper area of two-story rooms (foyers, family rooms) isnt counted as part of the floor plan. Likewise, stairs are only counted once. But not always. Check how volume is counted to be sure you know how big the plan really is. Plan services that design their own plans will have a consistent policy on area (and volume), but services that sell plans on consignment probably dont. How does the designer or plan service calculate the size of the plan? Sometimes that information is found on the services website or book, and sometimes you have to call to find out. But you should most definitely find out. Knowing how area and volume are measured can make a very big difference in the cost of the house you ultimately build. Conclusions Leave the Building to Builders. Damian Gillie/Construction Photography/Avalon/Getty Images The guest writer, Richard Taylor of RTA Studio, is an Ohio-based residential architect who creates luxury house plans and designs custom homes and interiors. Taylor spent eight years designing and renovating homes in German Village, an historic district in Columbus, Ohio. He has also designed custom homes in North Carolina, Virginia, and Arizona. He holds a B.Arch. (1983) from Miami University and is an active blog writer on social media. Taylor says: I believe that above all, a home should create a quality living experience as unique as the people that live in it, shaped by the owners heart, and by his image of home - thats the essence of custom design. Construction designs can get complicated, so let your building crew decipher the symbols the way they are trained to do. A couple of things for the homeowner to keep an eye on include the orientation of the building on the lot (where is south and the sun? where are the doors and windows?), the HVAC symbols (where is the ductwork?), and for future reference its good to know where your load-bearing walls will be located. And how big will your new house measure out to be? According to the U.S. Census Bureau Survey of Construction, the average new single-family American house was 2,392 square feet in 2010 and in 1973 it was 1,660 square feet. A small home is considered 1,000 to 1,500 square feet. And tiny homes? Could you live in less than 500 square feet? Thats the plan!

Evaluating practice through theories and models Essay - 1

Evaluating practice through theories and models - Essay Example He was being taken care of by his wife, who was elderly too. The patient had a history of heart failure, diabetes mellitus, and hypertension. His condition was worsened by the fact that he had a low self-esteem, to a point that he wished himself death to unburden his family. He had difficulty in breathing caused by increased ultra filtration. He also had limited water intake because of his renal treatment. In addition to this, he had failed in maintaining his regular food and water balance because he refused to eat and drink. Renal failure also caused him to have difficulty in passing urine (OSU 2013). Mr. Lim depended on his wife and nurses to help him with his activity of daily living (ADL). Mr. Lim and his wife both lacked the critical knowledge of maintaining his condition. These include lack of the will to follow his regimen and dietary adjustments (NKF 2013). Also captured were the psychological effects of the disease on him, and his family’s lack of motivation characterized by depression of both of them. Mr. Lim was negatively affected by these circumstances, and his condition, as a result. Introduction of Orem’s self-deficit theory seemed the best option to get the patient and his family to cope with management of the patient’s condition. Both the patient and his wife were to be subjected to Orem’s self-deficit theory to enable them gain the appropriate knowledge that will benefit all of them. This is because their lack of knowledge of self-care management and supportive education that was essential in Mr. Lim’s management of his chronic condition (Curtin et. al. 2005). Orem’s self-deficit theory was applied, in this case, to improve the condition of Mr. Lim and the psychological well being of his wife. The program took about three months, and the results were encouraging. Mr. Lim was able to portray a positive aura, which was the most essential step in the road to his recovery. This

Marketing Communications on The Smartphone Market Essay - 1

Marketing Communications on The Smartphone Market - Essay Example This research will begin with the statement that integrated marketing communications refer to systems used to plan communications in such a way as to benefit a business by disseminating its marketing campaigns more effectively and thereby lessening its marketing expenses. By integrating marketing structures such as social media avenues, advertising, telemarketing, and direct sales, one can bring more consistency and clarity into the message that is aimed at consumers. Mobile phone companies are constantly seeking an edge in the hyper-competitive mobile phone market by either increasing access speeds or introducing ever more robust application systems into their products. Naturally, these changes inspire marketing executives of mobile phone companies to come up with tactical and strategic marketing plans that allow them to be able to engage potential consumers through the different mobile platforms that are created. Google Inc. created an operating system, Android, that immediately ga ve it an edge in the Smartphone market. Its marketing scheme has played a great role in sustaining its competitiveness.
