Salinity Lab Report Essay Example

Saltiness Lab Report Paper On the off chance that you put these life forms in a jug and turn on the lights, you get photosynthesis. On the off chance that you turn off the lights, you turn off the essential creation. Haziness has no impact on breath. This is on the grounds that cell breath is really the converse procedure of photosynthesis. Oxygen is a need of life prerequisites for fundamentally all living beings. * In this lab we are trying how various degrees of saltiness in the water by implication influences the gross essential efficiency in sea-going plants. To quantify this you would utilize the light ND dim container technique. Just breath (R) can happen in the container put away in obscurity. The abatement in broke down oxygen in obscurity bottle after some time is a proportion of the pace of breath. Both photosynthesis and breath can happen in the jug presented to light, anyway the distinction between the measure of oxygen delivered through photosynthesis and that devoured through breath is the net essential profitability (NAP). The distinction in broke up oxygen after some time between the containers put away in the light and in obscurity is a proportion of the aggregate sum of oxygen delivered by photosynthesis. The aggregate sum of oxygen delivered is known as the gross essential efficiency (GAP). The condition for this technique is as followed: GAP= NAP + R NAP= light jug beginning DO R= starting DO-dull container Materials: 18 moll jars 2-1000 ml measuring glasses Stirrers salt Weigh pontoon Scale Distilled water Tap water Tape Sharpie Tin foil Dissolved oxygen test Compact plant leaves Dissolve oxygen test Plastic film Procedure: 1. Plug in and set up disintegrated oxygen test 2. Accumulate 18 jars 3. Separate the flagons into 3 gatherings (0. 25 g/ml, 0. 02 g/ml, and zero MGM/l) 4.

Name the following 6 flagons 0. 25 g/ml on the grounds that those flagons will have saltiness substance of 0. 25 g/ml. 6. Mark the last 6 jars 0. Egg/ml which will have saltiness substance of 0. 02 g/ml 7. Utilizing the scale and a gauge pontoon, weigh out 0. 25 grams of salt. 8. Fill the 1 liter container with faucet water and pour the 0. 25 grams of salt. 9. Blend and disperse the water to the 60. 25 g/ml jars. 10. Rehash stages 6 through 9 utilizing the necessary estimations. 11. Utilizing the broke down oxygen test measure and record the information for every one of the 18 cups. This quantitative information will be your underlying broken up oxygen. 12. Spot one reduced plant leaf into each cup and impermeable seal every carafe utilizing the plastic film. 13. Inside the 3 separate gatherings, split the cups into two gatherings. Enclose half of the gathering carafes by tin foil and the other half spot under lights. (I. E. : The 6 zero saltiness flagons will transform into two gatherings of 3. ) 14. Hold up 3 days and afterward record discoveries. Utilize this information to ascertain NAP, R, and GAP. Conversation: From the information gathered, I got negative GAP and R esteems which shows a mistake in the lab/information assortment. The gathering that wound up with a positive gross essential profitability was the 0. 02 MGM/l gathering. Every one of the 3 saltiness varieties had moderately a similar net essential efficiency, with 4 MGM/l being the most reduced and 4. 8 MGM/l being the most elevated. The measure of saltiness in the water likewise demonstrated no distinction in the plants breath. The most minimal was - 4. 7 MGM/l in both 0. MGM/l and the zero saltiness gatherings. The gathering with the most elevated measure of salt in the water had the most noteworthy breath, which isnt something that would occur, all things considered. Assessment: A primary wellspring of blunder in this lab was the kind of Lana we utilized. Either the salt didnt influence it much or it didnt photosynthesis just as we arranged. There was a blunder in the information assortment in light of the fact that the breath esteems and gross efficiency esteems were negative which would not occur, all things considered. Another issue with this lab is that it requires a long time to get everything set up on the principal day and can nearly take two days which would not work since you have to gather the underlying DO and taking over one day would not make the DO understanding introductory. End: My speculation was not upheld.

All About Abbreviations

About Abbreviations About Abbreviations About Abbreviations By Guest Author This is a visitor post by Letia Graening. A contraction is characterized as an abbreviated form of a word or expression. However, did you realize that there are a wide range of sorts of shortened forms? Here is a rundown of truncation types: Abbreviation †This structures a word utilizing the underlying parts or first letters of a name. For instance, ABBA, MADD, and OPEC are generally abbreviations that take the primary letter from each word to frame another word. Lesser realized abbreviations incorporate scuba and laser. The last models demonstrate that not all abbreviations must be promoted. Initialism Also called alphabetism, this is a gathering of letters, each articulated independently, utilized as a truncation for a name or articulation. Models include: CD, TV, and UK. Truncation This kind of condensing comprises just of the initial segment of a word. These are regularly utilized when alluding to appropriate titles, for example, months of the year or days of the week, e.g., Mon., Fri., Apr., Oct. Cut †Similar to truncation in that you are utilizing a piece of the word to shape the condensing, yet for this situation you’re utilizing either the center or end. Normal cut truncations incorporate telephone (phone) and cooler (fridge). Aphesis For this situation, you have dropped the unstressed vowel toward the start of the word. These are frequently accidental and calmly spoken adaptations of the words. Maybe the best model is cause rather than in light of the fact that. Portmanteau The mixing of at least two words will give you a portmanteau. A portion of my undisputed top choices incorporate liger (lion and tiger), spork (spoon and fork), skort (shorts and skirt), and brinner (breakfast and supper). A few interesting points when utilizing truncations: Anybody can make up a shortening and many are non-standard. They should, in this manner, be kept separate from formal composition. In the event that the full word would be promoted (e.g., Sunday or January), try to underwrite the contraction (e.g., Sun. or on the other hand Jan.).

Robotics

Robotics Once largely the province of science fiction, roboticss already permeate our daily lives. We may not realize it, as science fiction novels, television, and film have shaped our expectations of the appearance and function of robots. And those popular images of robots â€" machines like Wall-E, C-3P0, or the Terminator, do not yet exist. We do not live in a society where robots are as common in every household as silverware. However, not only are we headed there, already, robots of astounding functionality are in use around the world. Moreover, many corporations are racing to not only develop robots that meet our preconceived notions of what a robot should be, but also make them as ubiquitous as cellphones. Governments are striving to enhance their viability as weapons. In addition, academics are vigorously searching for singularity â€" the point at which robot intelligence will outstrip human intelligence. © Shutterstock.com | Willyam BradberryFueling all of this activity is the exciting field of robotics, which promises â€" or threatens â€" to transform our world in just a few short decades. In this article, we will look at, 1) definition of robotics, 2) history of robotics technology, 3) trends in robotics research, 3) semi-autonomous vs. autonomous robots, 4) robotics in industry and government, 5)  consumer robotics, 6) the future development of robotics technology, 7) the benefits of robotics technology, and 8) the ethical implications of robotics.DEFINITION OF ROBOTICSRobotics is the cross-disciplinary study of the design, development, and deployment of robots, which involves electronics, engineering, computer science, bioengineering, physics, philosophy, and psychology. We then must define robots, which is no easy task. In 1979, the Robot Institute of America defined robots as:A robot is a reprogrammable, multifunctional manipulator designed to move material, parts, tools or sp ecialized devices through variable programmed motions for the performance of a variety of tasks.Is a car then a robot? The Oxford Dictionary defines a robot as:“A machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer.”The first part is good, but the second part is clearly reflective of our popular conception of robots, and is contradicted by new biological tissue-based bio-robots, among other new developments. As the technology evolves, so too must the definition. For our purposes, we will define robots using the first part of the Oxford Dictionary definition, which is inclusive of not only new developments in robotics technology, but also the historical development of robots and robotics.A HISTORY OF ROBOTICS TECHNOLOGYScience historians generally credit the first robot to Archytas, an ancient Greek scholar and contemporary of Plato, who, in 350 BC, developed an artificial flying device whose form mimicked a bird’ s form and whose propulsion was powered by steam. Approximately 100 years later, the Greek inventor Ctesibus created automated clocks powered by water. These early inventions paved the way for further exploration of automated machines, with further advancements throughout the centuries leading to famed inventor Leonardo DaVinci’s robot â€" an armored knight in 1495; the Digesting Duck (robot) of French inventor Jacques de Vaucanson in 1739; and Swiss inventor Pierre Jacquet Droz’s animated dolls, built in the late 18th century. Most of the robots of the time were built to amuse and entertain European royalty; Droz’s dolls are notable for being programmable and a precursor to the modern computer.In 1822, Charles Babbage, an English scholar, invented (but never built) what is considered the first computer: a machine based on levers and gears, rather than the then-recently created electric circuit (by the Italian physicist Alessandro Volta in 1800). As computers are key to most robots in service today, as well as major fields of robotics study, it is worth noting here. Further advancements in mathematics, physics, mechanics, and electrical engineering over the next century and a half years led to the development of remote controlled robots. The term robot itself (from Czech writer Karel Capek’s play R.U.R. or Rossum’s Universal Robots) was popularized by science fiction writer Isaac Asimov, whose fiction has been influential on robo-ethics, and the term “artificial intelligence.”The 1950s, 1960s, and 1970s saw the rise of automated machines introduced for commercial manufacturing purposes as well as significant scientific explorations in artificial intelligence and biomechanics. However, beginning in the 1980s and early 1990s, robotics began to seep outside of the lab and into the hands of consumers, notably through LEGO robotics kits, which were simultaneously introduced to retail stores and classrooms. With the explosion of the Internet in the la te 1990s and the early 2000s, came a similar frenzied commercial drive to adapt robotics technologies, such as sensing, thinking, and acting, into electronically powered consumer products, thus blurring the line between what we think of as robots and actual robots. However, the Internet, and more specifically, the advent of the Digital or Information Age, also accelerated work on the development of service robots, military robots, research robots, and other machines strictly defined as robots.TRENDS IN ROBOTICS RESEARCHBecause robotics involves so many disciplines, approaches, and goals, there are dozens of different branches of robotics. They include, but are not limited to:Aerial robotics: the development of unmanned aerial vehicles (UAVs, commonly known as drones);Artificial intelligence: the development of self-thinking machines;Bio-robotics: the design of robots that emulate biological beings;Robot learning: the design and refinement of the way robot programming processes infor mation; andKinematics: the study of motion, in this case applied to robots.Fundamentally, some of the major trends in robotics research today that encompass most of robotics’ diverse branches include:Standardization: the creation of a common robot operating system;Miniaturization: which reflects advances in nanotechnology and medical applications for robots;Parallel processing: the development of robotics CPUs that mimic the human brain;Biological modeling: modeling robotic motion on human and animal motion; andIncreasing robotic autonomy.How Robots Will Change The World Documentary SEMI-AUTONOMOUS VS. AUTONOMOUS ROBOTSRobots are either semi-autonomous or autonomous. Semi-autonomous robots are those that are controlled manually by a human, or by their programming. They may be able to learn but that learning has a finite ceiling. Autonomous robots, in contrast, are those that can think, act, and adapt to sensory input. Completely autonomous robots are the ultimate goal of the arti ficial intelligence branch of robotics. However, while academics make strides towards that end, others work to refine the many semi-autonomous robots active today. Usually, these are found in industry and government, are known as service robots, and are designed to perform a specific function.ROBOTICS IN INDUSTRY AND GOVERNMENTManufacturingService robots have been utilized in industrial manufacturing processes to automate various phases of production since the 1960s. Most often, these robots are purely functional in design. One of the first industrial robots was an “arm,” created by George Devol in 1961, and used to manufacture auto parts at General Motors. Today, industrial robots have replaced millions of farmers, manufacturers, cargo loaders, and other labor-intensive occupations. Other jobs have arisen in new fields, but another wave of job displacement may arise with the advances in, and increased deployment of, semi-autonomous robots. The ability of service robots to learn and process complex information could lead to the deployment of robots in fields such as precision manufacturing, trucking, accounting, and even writing.MedicineRecent advances in robotics have been fueled in part by medical research and efforts by the medical community to improve the efficiency of healthcare delivery. Robots like Aethon TUG and the Vasteras Giraffe have been deployed in hospitals to deliver medicine and/or medical equipment throughout hospitals, and to enhance the delivery of medicine to homebound patients, respectively. Other examples include the Bestic, a robotic arm that helps delivery food to patients, and the Cosmobot, a robot design to enhance therapy techniques administered to developmentally disabled children.Robots have also been used increasingly in operations. Robots, such as the ZEUS Robotic Surgical System, have been in use since the late 1990s. Unmanned robotic surgeries have been available to patients since 2006. The burgeoning field of nano-medicin e is full of enthusiastic academic researchers devoted to deliver medicine in the body through nano-bots, which would act similar to antibodies. Unlike most robots, these would be made from biological tissue, rather than metal or polymers.Robotics technologies have also been employed in exoskeletons, to great effect. The firm ReWalk created an exoskeleton that, using sensing technologies, allows paraplegics to walk. It has been approved by the FDA for use, and while it currently costs approximately $70,000, advancements in these technologies as well as computer learning and processing power, may bring the price down in the coming years.MilitaryExoskeletons are not solely the province of medical research. Militaries, especially the U.S. military, have spent a considerable amount of time and money developing exoskeletons for infantry combat use. Such devices would allow soldiers to carry supplies and weapons effortlessly; some might even be capable of flight! They would also allow sol diers a full-range of motion, and be able to operate for long periods without charging. Currently, limitations include cost (as these would need to be produced in bulk to account for hundreds of thousands of soldiers), power limitations, and mobility issues.However, robots themselves have already been introduced on the battlefield. The U.S. Air Force uses aerial drones for surgical military strikes, and for reconnaissance. Other models of robots are used for ground-level reconnaissance, explosive device assessment and disposal, and equipment transportation. They range in size and form. For example, handheld “throwbots” can be pitched through a window or doorway and use their built-in recording equipment for surveillance. Security robotic systems, like the Packbot or TALON are often equipped with tires or treads to travel to a particular destination and perform a specified task. These models are small enough to be transported in a soldier’s backpack. By contrast, robots like th e ACER resemble a bulldozer and are designed for bomb disposal, transportation of weapons, and clearing roadway obstacles.In 2003, the U.S. Army initially announced a $130 billion program called Future Combat Systems that aimed to deploy armed robots in its military forces. However, the program was canceled in 2009 and its more promising initiatives swept into a general modernization program for brigade combat teams. Currently, the U.S., Britain, Israel, South Korea, and China use semi-autonomous robots in military combat.CONSUMER ROBOTICSOf course, not all robotics applications are used for such serious purposes. Consumer robots have been available as toys, pets, and household implements since the 1980s.FunctionsTo-date, consumer robots have generally fallen into one of four categories: toys, pets, social robots, and household implements. Starting with LEGO robotics kits, electronics and toy companies have raced each other to introduce viable robotic toys for kids. And beyond those kits, robot toys have proliferated, from the Tomy Verbot and Playskool Alphie of the 1980s to the Furbys and Sony AIBOs of the 1990s to the RoboSapiens and ASIMOs of today.Many robot toys come in the form of pets. Sony’s AIBO, a robotic toy that can learn and entertain, is a good example, appealing to more than just the market of robot enthusiasts. Indeed, pet robots are a good example of social robots â€" robots designed to provide people with companionship. These can range from the AIBO to dining companion robots such as the JIBO to adult entertainment robots, such as Roxxxy. Other robots, such as the Roomba, provide common household functions, such as vacuum cleaning.Roomba FeaturesThe features of most consumer robots parallel advances in the broader field of robotics. They are electro-mechanical (rather than biological) machines, and usually feature the latest in robot learning, sensing and motion technologies, though these are dependent on their primary function and price po int. Many can be integrated with your other electronics, such as your iPhone.CostsRobots available on the consumer market can retail for as little as $20.00 to as much as $10,000 or more. Generally, the more features the robot has, the more expensive it is. As robotic technologies become more inexpensive to produce, the price point will likely drop, as many electronics corporations would love to ensure the average household of the next ten years features at least one robot.Worlds 10 Most Amazing Robots FUTURE DEVELOPMENT OF ROBOTICS TECHNOLOGYWidespread adoptionMuch like popular fiction, scientists and futurists alike do predict that in the next few decades, robots will be in every household. However, few predict the proliferation of humanoid robots. Robotics technologies will instead be propagated throughout all types of electronic devices. This is already occurring. Self-driving cars and smart cities are prime examples. In addition, given that defense departments and healthcare co mpanies are driving investment in robotics technology RD to ensure productivity gains in the military and medicine, they are committed to adopting new technologies that meet safety, productivity, and cost standards.Increased functionalityAdvances in motion and sensing technologies will continue to improve the precision of robot motion, allowing robots to perform tasks once exclusively the domain of humans, as well as some tasks beyond our capabilities. Open sourcing robotics software development will likely yield answers to some tough problems facing roboticists now, but an eventual standardization of operating systems will likely yield the biggest breakthroughs.Integration with artificial intelligence researchEvery new breakthrough in robot learning brings us closer and closer to singularity. At some point in the not too distance future (Noted futurist, inventor and machine learning expert at Google, Ray Kurzweil, predicts by 2029) we will have the ability to develop fully autonomo us robots, which will bring new opportunities and challenges.NanotechnologyAdvances in nanotechnology will most notably have beneficial implications for healthcare, in terms of medicine delivery, healthcare monitoring, medical devices, and surgeries. However, nanotechnology has frightening implications for modern warfare and could, if weaponized, be as destructive as nuclear weapons. Beyond use in some consumer goods manufacturing, there is not much of a consumer market for nano-bots. Nevertheless, there soon might be.BENEFITS OF ROBOTICSAs robotics advances, the benefits of robot utilization grow exponentially. Service robots in industry have lowered production costs and created safer working environments. Military usage of robots has reduced casualties and collateral damage. Robots have also improved healthcare delivery and the advancement, and will likely continue to do so. Moreover, the proliferation of consumer robots may help us, not only in our daily lives, but also understan d ourselves better.ETHICAL IMPLICATIONS OF ROBOTICSRobotics presents us several potential ethical dilemmas, many of which have played out where robotics started â€" in popular fiction. Perhaps the most common ethical question is, if/when we, one day, create artificial intelligence, what is the role of the robot in our society? Even our current level of robotics technology has created a number of issues that we are already wrestling with, including, but not limited to:Privacy issues related to prosthetic devices and data chip implants, and the introduction of robots into policing;Ethical issues related to physical enhancements through robotics technology; the open sourcing of robotic design; the design of robots that can “breed” (create other robots); and the usage of robots in military operations; andPsychological, moral, and philosophical issues related to human interaction with service robots â€" industrial and personal.Introduction to Robotics[slideshare id=1025309doc=introdu ction-to-robotics-1234545871742906-2w=640h=330]

We drug ourselves out of bed and got ready for the long, tiring, 12 hour, car ride. About 4 hours away from Gulf Shores, Alabama, our final destination, we decided to stop at Bass Pro Shop in Birmingham, Alabama. At Bass Pro Shop we looked at hunting and camping accessories while stretching our legs and looking for snacks, so that we could continue straight to Gulf Shores.

After my grandparents arrived, we had a dinner of amazing, juicy burgers. Next we moved on to explore the beach. The sand was cool, and the small, sharp seashells stabbed at your feet as you walked. We watched the beautiful image of the sun sinking into the pink and orange sky as we felt and smelled the cold salt water against our feet. The next day, April 8th, my parents and I woke around 8 a.m. to get ready for our 3 mile run. After running, we spent a couple hours at the beach in the warm sun and chilly breeze. A little while later after having relaxed in the cool air conditioned condo, we got dressed up for dinner at a fancy seafood restaurant in town. On our way there, a group of girls in the car behind us were yelling out the window at their friends and rammed into the back of my grandpa’s truck. My grandpa was upset, so we didn’t make it to the restaurant until around tw o hours later. For dinner, I ordered a steak, and it was mouthwateringly juicy. When we arrived back to our cozy condo my grandparents went up to the rooms and my family and I went out to the beach. My mom and I had our phones so we turned on our flashlights and

Chapter 7: Review Question : 3 3Q) How do the Internet and Internet technology work, and how do they support communication and e-business? Ans) The Internet is a worldwide network of networks that uses the client/server model of computing and the TCP/IP network reference model. Every computer on the Internet is assigned a unique numeric IP address. The Domain Name System (DNS) converts IP addresses to more user-friendly domain names. We will write a custom essay sample on Huhuhu or any similar topic only for you Order Now Worldwide Internet policies are established by organizations and government bodies, such as the Internet Architecture Board (IAB) and the World Wide Web Consortium (W3C). Define the Internet, describe how it works, and explain how it provides business value. The Internet has become the world’s most extensive, public communication system that now rivals the global telephone system in reach and range. Most homes and small businesses connect to the Internet by subscribing to an Internet service e provider. An Internet service provider (ISP) is a commercial organization with a permanent connection to the Internet that sells temporary connections to retail subscribers. †¢Explain how the Domain Name System (DNS) and IP addressing system work. It would be incredibly difficult for Internet users to remember strings of 12 numbers; the Domain Name System (DNS) converts domain names to IP addresses. The domain name is the English-like name that corresponds to the unique 32-bit numeric IP address for each computer connected to the Internet. DNS servers maintain a database containing IP addresses mapped to their corresponding domain names. To access a computer on the Internet, users need only specify its domain name. DNS has a hierarchical structure. At the top of the DNS hierarchy is the root domain. The child domain of the root is called a top-level domain, and the child domain of a top-level domain is called is a second-level domain. The Internet is based on the TCP/IP networking protocol suite. Every computer on the Internet is assigned a unique Internet Protocol (IP) address, which currently is a 32-bit number represented by four strings of numbers ranging from 0 to 255 separated by periods. When a user sends a message to another user on the Internet, the message is first decomposed into packets using the TCP protocol. Each packet contains its destination address. The packets are then sent from the client to the network server and from there on to as many other servers as necessary to arrive at a specific computer with a known address. At the destination address, the packets are reassembled into the original message. †¢List and describe the principal Internet services. A client computer connecting to the Internet has access to a variety of services. These services include e-mail, electronic discussion groups, chatting and instant messaging, Telnet, File Transfer Protocol (FTP), and the Web. E-mail: E-mail enables messages to be exchanged from computer to computer, with capabilities for routing messages to multiple recipients, forwarding messages, and attaching text documents or multimedia files to messages. Although some organizations operate their own internal electronic mail systems, most e-mail today is sent through the Internet. The costs of e-mail is far lower than equivalent voice, postal, or overnight delivery costs, making the Internet a very inexpensive and rapid communications medium. Chatting: Many workplaces have employees communicating interactively using chat or instant messaging tools. Chatting enables two or more people who are simultaneously connected to the Internet to hold live, interactive conversations. Chat systems now support voice and video chat as well as written conversations. Many online retail businesses offer chat services on their Web sites to attract visitors, to encourage repeat purchases, and to improve customer service. Instant Messaging: Instant messaging is a type of chat service that enables participants to create their own private chat channels. The instant messaging system alerts the user whenever someone on his or her private list is online so that the user can initiate a chat session with other individuals. Instant messaging systems for consumers include Yahoo! Messenger, Google Talk, and Windows Live Messenger. Companies concerned with security use proprietary instant messaging systems such as Lotus Sametime. News Groups: Newsgroups are worldwide discussion groups posted on Internet electronic bulletin boards on which people share information and ideas on a defined topic, such as radiology or rock bands. Anyone can post messages on these bulletin boards for others to read. Many thousands of groups exist that discuss almost all conceivable topics. File Transfer Protocol(FTP): Transferring files from one computer to another computer. These files can be transferred through internet by using communication software’s like chatting, instant messaging and many. Web: The Web is the most popular Internet service. It’s a system with universally accepted standards for storing, retrieving, formatting, and displaying information using client/server architecture. Web pages are formatted using hypertext with embedded links that connect documents to one another and that also link pages to other objects, such as sound, video, or animation files. When you click a graphic and a video clip plays, you have clicked a hyperlink. †¢Define and describe VoIP and virtual private networks, and explain how they provide value to businesses. The Internet has also become a popular platform for voice transmission and corporate networking. Voice over IP (VoIP) technology delivers voice information in digital form using packet switching, avoiding the tolls charged by local and long-distance telephone networks. Calls that would ordinarily be transmitted over public telephone networks travel over the corporate network based on the Internet Protocol, or the public Internet. Voice calls can be made and received with a computer equipped with a microphone and speakers or with a VoIP-enabled telephone. Although there are up-front investments required for an IP phone system, VoIP can reduce communication and network management costs by 20 to 30 percent. A Virtual Private Network (VPN) is a secure, encrypted, private network that has been configured within a public network to take advantage of the economies of cale and management facilities of large networks, such as the Internet). A VPN provides your firm with secure, encrypted communications at a much lower cost than the same capabilities offered by traditional non-Internet providers who use their private networks to secure communications. VPNs also provide a network infrastructure for combining voice and data networks. Several competing protocol s are used to protect data transmitted over the public Internet, including Point-to-Point Tunneling Protocol (PPTP). †¢List and describe alternative ways of locating information on the Web. The various alternative ways of locating information on the Web are namely: Search Engines: Search engines attempt to solve the problem of finding useful information on the Web nearly instantly, and, arguably, they are the â€Å"killer app† of the Internet era. Today’s search engines can sift through HTML files, files of Microsoft Office applications, PDF files, as well as audio, video, and image files. There are hundreds of different search engines in the world, but the vast majority of search results are supplied by three top providers: Google, Yahoo! and Microsoft’s Bing search engine. Intelligent Agent Shopping Bots : Shopping bots use intelligent agent software for searching the Internet for shopping information. Shopping bots such as MySimon or Google Product Search can help people interested in making a purchase filter and retrieve information about products of interest, evaluate competing products according to criteria the users have established, and nego tiate with vendors for price and delivery terms. Many of these shopping agents search the Web for pricing and availability of products specified by the user and returns a list of sites that sell the item along with pricing information and a purchase link. Web-Blogs: A blog, the popular term for a Weblog, is a personal Web site that typically contains a series of chronological entries (newest to oldest) by its author, and links to related Web pages. The blog may include a blog roll (a collection of links to other blogs) and trackbacks (a list of entries in other blogs that refer to a post on the first blog Wiki’s: Wikis, in contrast, are collaborative Web sites where visitors can add, delete, or modify content on the site, including the work of previous authors. Wiki software typically provides a template that defines layout and elements common to all pages, displays user-editable software program code, and then renders the content into an HTML-based page for display in a Web browser. Social Networking: Social networking sites enable users to build communities of friends and professional colleagues. Members each typically create a â€Å"profile,† a Web page for posting photos, videos, MP3 files, and text, and then share these profiles with others on the service identified as their â€Å"friends† or contacts. Social networking sites are highly interactive, offer real-time user control, rely on user-generated content, and are broadly based on social participation and sharing of content and opinions. †¢Compare Web 2. 0 and Web 3. 0. Web 2. 0 facilitates interaction between web users and sites, so it allows users to interact more freely with each other. Web 2. 0 encourages participation, collaboration, and information sharing. This web 2. 0 is also called as â€Å"Second generation World Wide Web. † Examples of Web 2. 0 applications are Youtube, Wiki, Flickr, Facebook, and so on. This is also termed as ‘ read-write web ‘. Web 3. 0 is also called as â€Å"Semantic web† which means web for the future. In Web 3. 0, computers can interpret information like humans and intelligently generate and distribute useful content tailored to the needs of users. Web 3. 0 is known as the â€Å"Third generation of World Wide Web†. With the help of Web 3. 0, web content was easily carried in the form of natural language. It also consist of micro formats, natural language search, recommendation agents which are commonly known as AI i. e. Artificial Intelligence. One example of Web 3. 0 is Tivo, a digital video recorder. Its recording program can search the web and read what it finds to you based on your preferences. Reference: Kenneth C. Laudon , Jane P.

“Young Goodman Brown” by Nathaniel Hawthorne Essay Example For Students

â€Å"Young Goodman Brown† by Nathaniel Hawthorne Essay â€Å"Young Goodman Brown† by Nathaniel Hawthorne contains much symbolism. The symbols take many forms from the setting to the characters. The symbols can be viewed as just part of the story line, but apon further thought they represent many different things. Faith, Brown’s wife, is a symbol herself. When he says, â€Å"My love and my Faith,† he is using his wife as a symbol and is really referring to his love and faith in God. He goes on to say â€Å"this one night I must tarry away from thee. He means that he must part from his faith in God to carry on with his journey. He also says to the devil, â€Å" Faith kept me back awhile† and is making reference to a higher being that is trying to keep him from making his journey by delaying it. When Brown finds the pink ribbon that his wife was wearing lying in the forest he says, â€Å"my Faith is gone† and is referring to himself as losing his faith in God. Also, Goodman Brown’s â€Å"errand† symbolizes the Puritan voyage where they were to find the plan that God has set for them and let faith be their guidance. As Goodman Brown continues his â€Å"errand† and thing begin to go array he grows weak and falls to the ground. He begins to doubt whether there really was a Heaven above him and this is a key point when Goodman Browns faith begins to wain. Goodman Brown in panic declares that With Heaven above, and Faith below, I will yet stand firm against the devil! This is similar to a Puritan putting his faith in God and following â€Å"God’ Plan. † The forest that Goodman Brown ventures to in itself is a symbol. In the Puritan days the townspeople were barred from going into the forest because that is where evil lurked and even says â€Å" my father never went into the woods†¦nor his father before him. † Hawthorne described the forrest as â€Å" a dreary road, darkened by all the gloomiest trees of the forest† and even jokes of the evil lurking there when he says â€Å"there may be a devilish Indian behind every tree† and â€Å"What if the devil himself should be at my very elbow! † Hawthorne even uses the main character as a symbol. His name, Young Goodman Brown makes reference to him as being young and a good person. Then Hawthorne gives him such a common last name that it relates him to any and everybody, just like he does in one of his other short stories, â€Å"Everyman†, when he uses this as a reference to all of society. Another symbol that is present in the story is the mysterious man in the forest. He symbolizes the devil or evil in the story and strangely bears â€Å"a considerable resemblance to . † The Devil had with him a staff that bore the likeness of a great black snake. The staff, which looked like a snake, symbolizes the snake in the story of Adam and Eve. The snake led Adam and Eve to their destruction by leading them to the Tree of Knowledge, just as Brown is being led to unfathomed knowledge by the devil, and in turn is being led to his destruction. Just like Adam and Eve, when Brown finds the â€Å" fountain of all wicked arts† his faith is exiled from him just as Adam and Eve were cast from the garden. The story as a whole symbolizes that the potential for evil resides in everybody. The rest of Brown’s life is destroyed because of his inability to face the truth of sin and live with it. The story, which may have been a dream, and not a real life event, planted the seed of doubt in Browns mind, which him to lose his faith in his fellow man and leaves him alone and depressed. His life ends alone and miserable because he was never able to look at himself and realize that what he believed were everyone elses faults were his as well, and this led to his isolation from the community. Brown was buried with no hopeful verse upon his tombstone; for his dying hour was gloom.
