New Technology: Is It Worth the Hefty Cost?

Without fail, anytime a juicy bit of new technology hits the market, the exorbitant price tag puts it out of reach for even the middle class Americans. One of the latest inventions, Dyson's air multiplier, is no exception. I saw one for the first time at the mall last weekend, just 9.95, when I searched for a better deal on the internet I found them for only 9.95 with free shipping. This blade less fan looks like it came right of the set of one of those futuristic sci-fi flicks.

It comes as no great surprise that Dyson would be the one to create this super modern fan, but after revolutionizing the vacuum industry the bag less Dyson Ball, and the hand drying industry with the Dyson Air blade, this fan appears to be somewhat of a let down. While Dyson's other inventions have radically improved the performance over their competition, this fan doesn't seem to offer a significant improvement over the tried and true versions which have been used since Dr. Schulyer Wheeler, an American engineer who at the age of 22 invented the two bladed electric fan in 1886.

It does have a few redeeming characteristics. It is beautiful; compared to a standard circular fan it is practically a work of art. The thing is unquestionably different, it looks more like an ultra modern sculpture than it does a fan. I could easily picture one sitting on Captain Kirk's desk in his quarters on board the Enterprise. I do like the infinite speed control much better than the pre-programmed speeds you have to choose from on the other fans and it will certainly be easy to keep clean. Also, if you have young kids or pets around, the Dyson fan is unquestionably safer with no spinning blades to damage little fingers or paws.

New Technology: Is It Worth the Hefty Cost?

On the other hand, the Dyson fan is sadly deficient in other areas. The people at Dyson claim that; "The Air Multiplier quietly bathes users in a constant cool breeze." The breeze is smooth and steady, but the 12 inch model puts out no more volume of air than the ten inch fan sitting on my desk. It doesn't cool the air anymore than a conventional bladed fan and I've had hair dryers that made less noise than it does, in fact, my conventional fan is so quiet that I can barely hear it running at all, a trait that I treasure in my office. So it would seem that the Dyson Air Multiplier falls quite a bit short of accomplishing its boast. Without a doubt, Dyson now has the most ludicrously overpriced fan on the market today, but if you are shopping more for looks than functionality, or if you just happen to be looking for a great conversation piece, then by all means run out and buy you one.

In the past, I have often found myself at odds with the findings of the panelists at Consumer Reports Magazine but in their July 2010 issue they didn't give it any more of a thumbs up than I did. In fact, they ended their report by saying, "You'll save a good 4.99 by buying a conventional fan."

The sad part is that for the same cost of one Dyson Air Multiplier that will almost cool one person, I can go buy three small window air conditioners and cool three small rooms down close to the temperature of a refrigerator. I for one give my vote to the air conditioners.

Another emerging technology is electro chromic windows or smart windows. With the turn of a switch these windows change from transparent to opaque or shaded by an electric signal. This will make traditional window shades and blinds obsolete. There are several companies offering these windows but they are so expensive that they don't even have price lists. The windows are custom built and the pricing is all done by quotes.

The newest technology always comes with a top heavy price tag and I used to pay it. I remember paying seven hundred and fifty dollars for my first VCR, the last one only cost me a measly sixty nine dollars. When I bought my first Camcorder I shelled out a whopping 00.00, but the one sitting on the shelf in my office right now I paid less than 0.00 for and it will run circles around that first antique. My first internet ready computer cost me over two grand, it had a whole ¼ gig hard drive and a whopping 56 megs of ram. My cell phone has more computing power than that computer did and for only a fraction of the cost, not to mention that it will fit into my shirt pocket.

No, I no longer run out and purchase the newest technology when it first comes out, instead, I wait for China to copy and mass-produce it for hundreds of dollars less and anymore, you don't have to wait very long at all to get the cheaper version. I'd be willing to bet that by the time you start thinking about fans in 2011, the Chinese version will be on the market, maybe theirs will even be quieter.

Role of Information Technology in Growth of Business

Information technology (IT) refers to the management and use of information using computer-based tools. It includes acquiring, processing, storing, and distributing information. Most commonly it is a term used to refer to business applications of computer technology, rather than scientific applications. The term is used broadly in business to refer to anything that ties into the use of computers.

Mostly businesses today create data that can be stored and processed on computers. In some cases the data must be input to computers using devices such as keyboards and scanners. In other cases the data might be created electronically and automatically stored in computers.

Small businesses generally need to purchase software packages, and may need to contract with IT businesses that provide services such as hosting, marketing web sites and maintaining networks. However, larger companies can consider having their own IT staffs to develop software, and otherwise handle IT needs in-house. For instance, businesses working with the federal government are likely to need to comply with requirements relating to making information accessible.

Role of Information Technology in Growth of Business

The constant upgrade in information technology, along with increasing global competition, is adding difficulty and hesitation of several orders of scale to the business and trade. One of the most widely discussed areas in recent business literature is that of new organizational network structures that hold survival and growth in an environment of growing complexity.

Effective implementation of information technology would decrease liability by reducing the cost of expected failures and increase flexibility by reducing the cost of adjustment. The businesses reaction to the environment remains to be the vital determinant for its effectiveness. The capabilities and flexibilities of computer-communication systems make them gradually more appropriate to businesses by being able to respond to any specific information or communication requirement.

Information Technology is having impact on all trade industries and businesses, in service as well as in manufacturing. It is affecting workers at all levels of organizations, from the executives to middle management and clerks. Information technology is increasingly becoming a basic factor of all types of technologies such as craft, engineering, routine, and non-routine.

The advances in Information Technology would result in remarkable decline in the costs of synchronization that would lead to new, concentrated business structures. It enables the business to respond to the new and urgent competitive forces by providing effective management of interdependence.

In the near future businesses would be facing a lack and a redundancy of information called information glut. To solve the information-glut companies will need to introduce methods for selective thinning out of information. Improvements in telecommunications will make it easier to control business units dispersed over different parts of the world. Advances in telecommunications, would result in increased distance-communication. Indirect communication would be preferred for well-structured information for routine, preprogrammed and decision processes.

My Xbox 360 Has the Red Ring of Death - What to Do Next?

The Xbox 360 is an excellent piece of machinery that is worthy of great recognition, however recently the console has been plagued with a major hardware error, which is commonly known as the red ring of death. This could be due to the fact that The 360 was rushed along in the production process in order to beat the PS3, or simply because the designers overlooked a major design flaw.

Nonetheless, whatever the reason may be, many dedicated gamers are extremely frustrated with the problem and are seeking a permanent fix, as it is something that cannot be repaired very easily or quickly without the right information. Some gamers have been through as many as 4 gaming consoles in order to combat this problem; and guess what? There is no guarantee that Microsoft will send them a fifth console which won't encounter the same problem again. Luckily for you, I have discovered a way to permanently rid yourself of the red ring of death for good and it doesn't involve sending your console away to Microsoft or pay for costly repairs.

Refurbished

But before we go into the remedy for the red ring of death lets look at exactly what the red lights mean. Firstly you may be in luck and not be suffering from the red ring of death; if your Xbox only displays 1 red light then it means you are having a general hardware failure. This isn't all that major and it can generally be fixed by disconnecting and reconnecting the cables or Removing and re-inserting the hard drive, contact Microsoft customer support if the problem persists. 2 red lights on your button indicate that the system is beginning to overheat, if you see this warning then immediately turn the console off and let it cool down before resuming play, also try keep it in a well ventilated area for future use. If your AV plug is loose, then your XBox 360 will show 4 red lights, this is a simple problem and it can be easily fixed by plugging the cord back in its place.

My Xbox 360 Has the Red Ring of Death - What to Do Next?

Well if you aren't presented with any of the above symbols and are seeing 3 red lights, then I'm afraid your console has been contaminated with the red ring of death and your console is pretty much a regular piece of junk until you have it repaired. The red ring of death is caused due to one major problem and that is excessive overheating. The trouble is that during intense game play the heat sinks within the console become so hot that they eventually melt the thermal compounds between the CPU and GPU. This causes a general hardware failure within the console and you are presented with the Red Ring of Death to inform you of the malfunction.

Now, if you are seeking a solution to the dreaded problem then you have a few options at your disposal:

1. You can send you console back to Microsoft and have them fix it. This is an easy process however it can be a lengthy one, as it could take upto 8 weeks to get your console back. Also you will most probably receive a different refurbished console which could encounter the same problem in the future. As I mentioned earlier some gamers have been through as many as 4 consoles only to see their fifth console become doomed again.

2. Although I don't recommend it, you could attempt the infamous Towel Trick. You would've most likely heard of this solution already, and even though it works (only temporarily for about 30 mins) it is not a permanent fix and you could cause serious damage to your console in the process.

3. The third option is to repair the red ring of death yourself, with the aid of a quality Online Repair guide, that will run you through the repair process step by step using online videos and tutorials.

So what is the best option? That is totally upto you and you can decide on whichever option you wish to choose, however personally, I would recommend staying away from the towel trick. Option 1 is probably your best choice if you still have warranty and don't want to attempt any repairs yourself. If you don't have warranty then you will have to pay around 0 to have it repaired.

But seriously, why would you want to wait months to receive a repaired Xbox 360 that doesn't even come back repaired? Instead you could fix it yourself within the comfort of your own home with an easy to follow repair guide, these guides have plenty of information and they will walk you through the repair process using online videos and detailed instructions, they even offer live customer support that should help get your console back in action within an hour. The guides also come with a full money back guarantee, so if for some reason you cannot fix your console they will refund your money immediately.

My Xbox 360 Has the Red Ring of Death - What to Do Next?

So if you're Xbox 360 is suffering from the deadly Red Ring Of Death, then check out this Tutorial on how you can fix your Xbox within a couple of hours using the 3 Red Light Fix Repair Guide. I personally used this guide to fix my own Xbox back in the day, it's the first and original guide to be written on the subject and believe me it's the only help you will ever need to permanently fix your Xbox 360.

History of Educational Technology

There is no written evidence which can tell us exactly who has coined the phrase educational technology. Different educationists, scientists and philosophers at different time intervals have put forwarded different definitions of Educational Technology. Educational technology is a multifaceted and integrated process involving people, procedure, ideas, devices, and organization, where technology from different fields of science is borrowed as per the need and requirement of education for implementing, evaluating, and managing solutions to those problems involved in all aspects of human learning.

Educational technology, broadly speaking, has passed through five stages.

The first stage of educational technology is coupled with the use of aids like charts, maps, symbols, models, specimens and concrete materials. The term educational technology was used as synonyms to audio-visual aids.

History of Educational Technology

The second stage of educational technology is associated with the 'electronic revolution' with the introduction and establishment of sophisticated hardware and software. Use of various audio-visual aids like projector, magic lanterns, tape-recorder, radio and television brought a revolutionary change in the educational scenario. Accordingly, educational technology concept was taken in terms of these sophisticated instruments and equipments for effective presentation of instructional materials.

The third stage of educational technology is linked with the development of mass media which in turn led to 'communication revolution' for instructional purposes. Computer-assisted Instruction (CAI) used for education since 1950s also became popular during this era.

The fourth stage of educational technology is discernible by the individualized process of instruction. The invention of programmed learning and programmed instruction provided a new dimension to educational technology. A system of self-learning based on self-instructional materials and teaching machines emerged.

The latest concept of educational technology is influenced by the concept of system engineering or system approach which focuses on language laboratories, teaching machines, programmed instruction, multimedia technologies and the use of the computer in instruction. According to it, educational technology is a systematic way of designing, carrying out and evaluating the total process of teaching and learning in terms of specific objectives based on research.

Educational technology during the Stone Age, the Bronze Age, and the Iron Age
Educational technology, despite the uncertainty of the origin of the term, can be traced back to the time of the three-age system periodization of human prehistory; namely the Stone Age, the Bronze Age, and the Iron Age.

Duringthe Stone Age, ignition of fire by rubbing stones, manufacture of various handmade weapon and utensils from stones and clothing practice were some of the simple technological developments of utmost importance. A fraction of Stone Age people developed ocean-worthy outrigger canoe ship technology to migrate from one place to another across the Ocean, by which they developed their first informal education of knowledge of the ocean currents, weather conditions, sailing practice, astronavigation, and star maps. During the later Stone Age period (Neolithic period),for agricultural practice, polished stone tools were made from a variety of hard rocks largely by digging underground tunnels, which can be considered as the first steps in mining technology. The polished axes were so effective that even after appearance of bronze and iron; people used it for clearing forest and the establishment of crop farming.

Although Stone Age cultures left no written records, but archaeological evidences proved their shift from nomadic life to agricultural settlement. Ancient tools conserved in different museums, cave paintings like Altamira Cave in Spain, and other prehistoric art, such as the Venus of Willendorf, Mother Goddess from Laussel, France etc. are some of the evidences in favour of their cultures.

Neolithic Revolution of Stone Age resulted into the appearance of Bronze Age with development of agriculture, animal domestication, and the adoption of permanent settlements. For these practices Bronze Age people further developed metal smelting, with copper and later bronze, an alloy of tin and copper, being the materials of their choice.

The Iron Age people replaced bronze and developed the knowledge of iron smelting technology to lower the cost of living since iron utensils were stronger and cheaper than bronze equivalents. In many Eurasian cultures, the Iron Age was the last period before the development of written scripts.

Educational technology during the period of Ancient civilizations
According to Paul Saettler, 2004, Educational technology can be traced back to the time when tribal priests systematized bodies of knowledge and ancient cultures invented pictographs or sign writing to record and transmit information. In every stage of human civilization, one can find an instructional technique or set of procedures intended to implement a particular culture which were also supported by number of investigations and evidences. The more advanced the culture, the more complex became the technology of instruction designed to reflect particular ways of individual and social behaviour intended to run an educated society. Over centuries, each significant shift in educational values, goals or objectives led to diverse technologies of instruction.

The greatest advances in technology and engineering came with the rise of the ancient civilizations. These advances stimulated and educated other societies in the world to adopt new ways of living and governance.

The Indus Valley Civilization was an early Bronze Age civilization which was located in the northwestern region of the Indian Subcontinent. The civilization was primarily flourished around the Indus River basin of the Indus and the Punjab region, extending upto the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab, (most of the part is under today's Pakistan and the western states of modern-day India as well as some part of the civilization extending upto southeastern Afghanistan, and the easternmost part of Balochistan, Iran).

There is a long term controversy to be sure about the language that the Harappan people spoke. It is assumed that their writing was at least seems to be or a pictographic script. The script appears to have had about 400 basic signs, with lots of variations. People write their script with the direction generally from right to left. Most of the writing was found on seals and sealings which were probably used in trade and official & administrative work.

Harappan people had the knowledge of the measuring tools of length, mass, and time. They were the first in the world to develop a system of uniform weights and measures.

In a study carried out by P. N. Rao et al. in 2009, published in Science, computer scientists found that the Indus script's pattern is closer to that of spoken words, which supported the proposed hypothesis that it codes for an as-yet-unknown language.

According to the Chinese Civilization, some of the major techno-offerings from China include paper, early seismological detectors, toilet paper, matches, iron plough, the multi-tube seed drill, the suspension bridge, the wheelbarrow, the parachute, natural gas as fuel, the magnetic compass, the raised-relief map, the blast furnace, the propeller, the crossbow, the South Pointing Chariot, and gun powder. With the invent of paper they have given their first step towards developments of educational technology by further culturing different handmade products of paper as means of visual aids.

Ancient Egyptian language was at one point one of the longest surviving and used languages in the world. Their script was made up of pictures of the real things like birds, animals, different tools, etc. These pictures are popularly called hieroglyph. Their language was made up of above 500 hieroglyphs which are known as hieroglyphics. On the stone monuments or tombs which were discovered and rescued latter on provides the evidence of existence of many forms of artistic hieroglyphics in ancient Egypt.

Educational technology during Medieval and Modern Period
Paper and the pulp papermaking process which was developed in China during the early 2nd century AD, was carried to the Middle East and was spread to Mediterranean by the Muslim conquests. Evidences support that a paper mill was also established in Sicily in the 12th century. The discovery of spinning wheel increased the productivity of thread making process to a great extent and when Lynn White added the spinning wheel with increasing supply of rags, this led to the production of cheap paper, which was a prime factor in the development of printing technology.

The invention of the printing press was taken place in approximately 1450 AD, by Johannes Gutenburg, a German inventor. The invention of printing press was a prime developmental factor in the history of educational technology to convey the instruction as per the need of the complex and advanced-technology cultured society.

In the pre-industrial phases, while industry was simply the handwork at artisan level, the instructional processes were relied heavily upon simple things like the slate, the horn book, the blackboard, and chalk. It was limited to a single text book with a few illustrations. Educational technology was considered synonymous to simple aids like charts and pictures.

The year 1873 may be considered a landmark in the early history of technology of education or audio-visual education. An exhibition was held in Vienna at international level in which an American school won the admiration of the educators for the exhibition of maps, charts, textbooks and other equipments.

Maria Montessori (1870-1952), internationally renowned child educator and the originator of Montessori Method exerted a dynamic impact on educational technology through her development of graded materials designed to provide for the proper sequencing of subject matter for each individual learner. Modern educational technology suggests many extension of Montessori's idea of prepared child centered environment.

In1833, Charles Babbage's design of a general purpose computing device laid the foundation of the modern computer and in 1943, the first computing machine as per hi design was constructed by International Business Machines Corporation in USA. The Computer Assisted instruction (CAI) in which the computer functions essentially as a tutor as well as the Talking Type writer was developed by O.K. Moore in 1966. Since 1974, computers are interestingly used in education in schools, colleges and universities.

In the beginning of the 19th century, there were noteworthy changes in the field of education. British Broadcasting Corporation (BBC), right from its start of school broadcasts in 1920 had maintained rapid pace in making sound contribution to formal education. In the USA, by 1952, 20 states had the provision for educational broadcasting. Parallel to this time about 98% of the schools in United Kingdom were equipped with radios and there were regular daily programmes.

Sidney L. Pressey, a psychologist of Ohio state university developed a self-teaching machine called 'Drum Tutor' in 1920. Professor Skinner, however, in his famous article 'Science of Learning and art of Teaching' published in 1945 pleaded for the application of the knowledge derived from behavioral psychology to classroom procedures and suggested automated teaching devices as means of doing so.

Although the first practical use of Regular television broadcasts was in Germany in 1929 and in 1936 the Olympic Games in Berlin were broadcasted through television stations in Berlin, Open circuit television began to be used primarily for broadcasting programmes for entertainment in 1950. Since 1960, television is used for educational purposes.

In 1950, Brynmor, in England, used educational technological steps for the first time. It is to be cared that in 1960, as a result of industrial revolution in America and Russia, other countries also started progressing in the filed of educational technology. In this way, the beginning of educational technology took place in 1960 from America and Russia and now it has reached England, Europe and India.

During the time of around 1950s, new technocracy was turning it attraction to educations when there was a steep shortage of teachers in America and therefore an urgent need of educational technology was felt. Dr. Alvin C. Eurich and a little later his associate, Dr. Alexander J. Stoddard introduced mass production technology in America.

Team teaching had its origin in America in the mid of 1950's and was first started in the year 1955 at Harvard University as a part of internship plan.

In the year 1956, Benjamin Bloom from USA introduced the taxonomy of educational objectives through his publication, "The Taxonomy of Educational Objectives, The Classification of Educational Goals, Handbook I: Cognitive Domain".

In 1961, Micro teaching technique was first adopted by Dwight W. Allen and his co-workers at Stanford University in USA.

Electronics is the main technology being developed in the beginning of 21st century. Broadband Internet access became popular and occupied almost all the important offices and educational places and even in common places in developed countries with the advantage of connecting home computers with music libraries and mobile phones.

Today's classroom is more likely to be a technology lab, a room with rows of students using internet connected or Wi-Fi enabled laptops, palmtops, notepad, or perhaps students are attending a video conferencing or virtual classroom or may have been listening to a podcast or taking in a video lecture. Rapid technological changes in the field of educational have created new ways to teach and to learn. Technological changes also motivated the teachers to access a variety of information on a global scale via the Internet, to enhance their lessons as well as to make them competent professional in their area of concern. At the same time, students can utilize vast resources of the Internet to enrich their learning experience to cope up with changing trend of the society. Now a days students as well teachers are attending seminars, conferences, workshops at national and international level by using the multimedia techno-resources like PowerPoint and even they pursue a variety of important courses of their choice in distance mode via online learning ways. Online learning facility has opened infinite number of doors of opportunities for today's learner to make their life happier than ever before.
