How Does the Internet Work?
TheThe Internet is a worldwide collection of computer networks, cooperating with each other to exchange data using a common software standard. Through telephone wires and satellite links, Internet users can share information in a variety of forms. The size, scope and design of the Internet allows users to:

connect easily through ordinary personal computers and local phone numbers;
exchange electronic mail (E-mail) with friends and colleagues with accounts on the Internet;
post information for others to access, and update it frequently;
access multimedia information that includes sound, photographic images and even video; and
access diverse perspectives from around the world.
An additional attribute of the Internet is that it lacks a central authority—in other words, there is no "Internet, Inc." that controls the Internet. Beyond the various governing boards that work to establish policies and standards, the Internet is bound by few rules and answers to no single organization.

Many people think that the Internet is a recent innovation, when in fact the essence of it has been around for over a quarter century. The Internet began as ARPAnet, a U.S. Department of Defense project to create a nationwide computer network that would continue to function even if a large portion of it were destroyed in a nuclear war or natural disaster.

During the next two decades, the network that evolved was used primarily by academic institutions, scientists and the government for research and communications. The appeal of the Internet to these bodies was obvious, as it allowed disparate institutions to connect to each others' computing systems and databases, as well as share data via E-mail.

The nature of the Internet changed abruptly in 1992, when the U.S. government began pulling out of network management, and commercial entities offered Internet access to the general public for the first time. This change in focus marked the beginning of the Internet's astonishing expansion.

According to a survey conducted by CommerceNet and Nielsen Media Research in early 1997, nearly one out of every four Americans over the age of 16 is an Internet user. And the number of users worldwide is believed to be well into the tens of millions. Other statistics are equally startling:

• A CNN report stated that Internet traffic in 1996 was 25 times what it was just two years earlier.
• The market research group IntelliQuest pegged the number of Internet users in the U.S. in late 1996 at 47 million - a 34 percent increase over the first quarter of that year.
• According to IBM, 146 countries currently have at least some level of Internet access.
• The technology research firm IDG estimates that by century's end, one billion people worldwide will have access to personal computers—more than doubling the computer-savvy population of 1996.

The Internet explosion coincides with the advent of increasingly powerful yet reasonably priced personal computers with easy-to-use graphical operating systems. The result has been an attraction of recent computer "converts" to the network, and new possibilities for exploiting a wealth of multimedia  capabilities.

2.you tube

YouTube is a video-sharing website on which users can upload, share, and view videos, created by three former PayPal employees in February 2005.[3]
Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, BBC, Vevo, Hulu and other organizations offer some of their material via the site, as part of the YouTube partnership program.[4]
Unregistered users may watch videos, and registered users may upload an unlimited number of videos. Videos that are considered to contain potentially offensive content are available only to registered users 18 and older. In November 2006, YouTube, LLC was bought by Google Inc. for $1.65 billion, and now operates as a subsidiary of Google.

YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, who were all early employees of PayPal.[5] Hurley had studied design at Indiana University of Pennsylvania, while Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign

The first YouTube video was entitled Me at the zoo, and shows founder Karim at the San Diego Zoo.[11] The video was uploaded on April 23, 2005, and can still be viewed on the site.[12]
YouTube offered the public a beta test of the site in May 2005, six months before the official launch in November 2005. The site grew rapidly, and in July 2006 the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day.
3.Large Hadron Collider

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature.

The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (574 ft) beneath the Franco-Swiss border near Geneva, Switzerland. This synchrotron is designed to collide opposing particle beams of either protons at an energy of 7 teraelectronvolts (7 TeV or 1.12microjoules) per particle, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus.^[1][2] The term hadron refers to particles composed of quarks.

The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics, including the existence of the hypothesized Higgs boson^[3] and of the large family of new particles predicted by supersymmetry.^[4] It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories

Operational history

The first beam was circulated through the collider on the morning of 10 September 2008.[31] CERN successfully fired the protons around the tunnel in stages, three kilometres at a time. The particles were fired in a clockwise direction into the accelerator and successfully steered around it at 10:28 local time.[32] The LHC successfully completed its first major test: after a series of trial runs, two white dots flashed on a computer screen showing the protons travelled the full length of the collider. It took less than one hour to guide the stream of particles around its inaugural circuit.[33] CERN next successfully sent a beam of protons in a counterclockwise direction, taking slightly longer at one and a half hours due to a problem with the cryogenics, with the full circuit being completed at 14:59.

On 19 September 2008, a quench occurred in about 100 bending magnets in sectors 3 and 4, causing a loss of approximately six tonnes of liquid helium, which was vented into the tunnel, and a temperature rise of about 100 kelvin in some of the affected magnets. Vacuum conditions in the beam pipe were also lost.[34] Shortly after the incident CERN reported that the most likely cause of the problem was a faulty electrical connection between two magnets, and that – due to the time needed to warm up the affected sectors and then cool them back down to operating temperature – it would take at least two months to fix it.[35] Subsequently, CERN released a preliminary analysis of the incident on 16 October 2008,[36] and a more detailed one on 5 December 2008.[37] Both analyses confirmed that the incident was indeed initiated by a faulty electrical connection. A total of 53 magnets were damaged in the incident and were repaired or replaced during the winter shutdown

4.web camera

A webcam is a video camera which feeds its images in real time to a computer or computer network, often via USB, ethernet or Wi-Fi.

Their most popular use is the establishment of video links, permitting computers to act as videophones or videoconference stations. This common use as avideo camera for the World Wide Web gave the webcam its name. Other popular uses include security surveillance and computer vision.

Webcams are known for their low manufacturing cost and flexibility, making them the lowest cost form of videotelephony. They have also become a source of security and privacy issues, as some built-in webcams can be remotely activated via spyware.

Early development

First developed in 1991, a webcam was pointed at the Trojan Room coffee pot in the Cambridge University Computer Science Department. The camera was finally switched off on August 22, 2001. The final image captured by the camera can still be viewed at its homepage The oldest webcam still operating is FogCam at San Francisco State University, which has been running continuously since 1994.

5.GPS NAVIGATOR

An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drivetrain, a gyroscope and an accelerometercan be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban canyons or tunnels.

Some sorts can be taken out of the car and used hand-held while walking.

Steven Lobbezoo developed the first commercially available satellite navigation system for cars. It was produced in Berlin from start 1984 to January 1986. Publicly presented first at the Hannover fair in 1985 in Germany, the system was shown in operation on the evening news (item in the Hannover fair) from the first German television channel in that year. It used a modified IBM PC, a large disc for map data and a flat screen, built into the glove compartment. It was called Homer (after the device from a James Bond movie).

Alpine claims to have created the first automotive navigation system in 1981. However, according to the company's own historical timeline,the company claims to have co-developed an analog automotive navigation product called the Electro Gyrocator, working with Honda. This engineering effort was abandoned in 1985. Although there are reports of the Electro Gyrocator being offered as a dealer option on the Honda Accord in 1981, it's not clear whether an actual product was released, whether any customers took delivery of an Electro Gyrocator-equipped Accord, or even whether the unit appeared in any dealer showrooms; Honda's own official history appears to pronounce the Electro Gyrocator as not practical. See below for Honda's history of the project.

Honda claimsto have created the first navigation system starting in 1983, and culminating with general availability in the 1990 Acura Legend. The original analog Electro Gyrocator system used an accelerometer to navigate using inertial navigation, as the GPS system was not yet generally available. However, it appears from Honda's concessions in their own account of the Electro Gyrocator project that Etak actually trumped Honda's analog effort with a truly practical digital system, albeit one whose effective range of operation was limited by the availability of appropriately digitized street map data.

6.IPOD

The Apple iPod line has been upgraded many times, and each significant revision is called a "generation". Only the most recent (highest numbered) generation and refurbished units of previous generations of the iPod line are available from Apple for each model (classic, nano, shuffle, touch). Each new generation usually has more features and refinements while typically being physically smaller and lighter than its predecessor, while usually (but not always) retaining the older model's price tag. Notable changes include the touch-sensitive click wheel replacing the mechanical scroll wheel, use of color displays, and flash memory replacing hard disks.

7.YOTA

Yota (Russian: Йота) is the trademark of a Russian multinational telecommunications services provider (primarily high speed mobile broadband, with some video, TV and music services)Yota currently operates in Russia, Belarus and Nicaragua and will launch in Peru very soon^] Having launched as a flagship WiMAX technlogy base, in May 2010, it announced a move to LTE.

Since launch, Yota has promised unlimited, high-speed, mobile internet access to its customers.

Laptops of the future

http://www.youtube.com/watch?v=7H0K1k54t6A,

The Future of Laptops and Notebooks is going to be one of the Craziest thing that is going to happen in the future. With theVideo shown, we come to a conclusion that you need not purchase a briefcase for your laptop and also throw away all the Tablet PC’s that we are getting released now from different Big Companies like the Toshiba,
MSI, Apple, etc.
The Future of Laptops is something like a bag which is going to hang on your shoulder and look like a Cool Mattress that hangs like a gym Bag. But when you roll your your future laptop it totally becomes a Slate what we have in the market. The complete thing would become a large multi touch screen with the USB ports and stylus to play around  with.So it comes like a complete package with all features of the computers till date. It would have Multitouch screen, USB Ports, Web cam, and would have all the features with the best feature of molding into a bag like structure when not in use. Watch out the Video for more adventure.(http://cnettv.cnet.com/future-laptops/9742-1_53-50083277.html)

2050. People made ​​a big leap forward, new discoveries in medicine, construction(building resistant to earthquakes), cars are charged with environmentally friendly fuel.Everyone at home has a technique which is much easier work

http://vkontakte.ru/video3342683_159525808-laptops today,as well   as rugs and windows, which are able to cleanse itself,

I'll have a car.
you can now transform your love for those turntables into another interesting activity we all enjoy, eating. This design is one among the few that looks at the lighter side of life. This dining tray is primarily designed to match turntables, making eating more fun than before. Well, Emir Rifat Isik puts it well, “turntable + dining tray = fun design.” This quirky and compact model shows skillful blend of musical dining set. The dining tray features fork and knife, salt and pepper shakers and a base. Well, it is only a concept as of now and no information regarding its initial prototype has hit the media yet

All the people at home will be robots!!!.  we have acting robots – I know, it won’t make much of a film – we also have robots which can mimic facial expressions. But when, where, and why, will we get to see and use, a robot that can go to the fridge, pull out a Bud so you can sit back and amuse yourself on the latest release of the PlayStation 27.

However, Robots are picking up pace, and seem to grow immensely superior. So expect Robots to be already here by 2050, and themselves, picking their artificial brains, trying to uncover new technology, before 2050?

1.The microwave oven was invented as an accidental by-product of war-time (World War 2) radar research using magnetrons (vacuum tubes that produce microwave radiation, a type of electromagnetic radiation that has a wavelength between 1 mm and 30 cm).

In 1946, the engineer Dr. Percy LeBaron Spencer, who worked for the Raytheon Corporation, was working on magnetrons. One day at work, he had a candy bar in his pocket, and found that it had melted. He realized that the microwaves he was working with had caused it to melt. After experimenting, he realized that microwaves would cook foods quickly - even faster than conventional ovens that cook with heat.

2.A laptop (notebook)^[1][2] is a personal computer for mobile use.^[3][4][5] A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. A laptop battery in new condition typically stores enough energy to run the laptop for three to five hours, depending on the computer usage, configuration and power management settings. When the laptop is plugged into the mains, the battery charges, whether or not the computer is running.

Portable computers, originally monochrome CRT-based and developing into the modern laptop, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, and cheaper and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes.

3.A Dishwasher  is a mechanical device for cleaning dishes and eating utensils. Dishwashers can be found in restaurants and private homes.

Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 55 to 75 °C (130 to 170 °F) at the dishes, with lower temperatures used for delicate items. A mix of water and detergent is used for cleaning purposes, followed by clean water to remove the detergent residue. Some dishwashers have multiple wash and rinse periods within the complete cycle. In some dishwashers, a rinsing aid (also called rinse aid) can be added to the rinse cycle to improve drying and avoid water spots remaining on dry items.

4.Fridge (band) 

 are an English post-rock band, comprising school friends Kieran Hebden, Adem Ilhan, and Sam Jeffers. Initially Hebden played guitar, Ilhan bass, and Jeffers drums, but Hebden and Ilhan soon adopted a variety of other instruments, and by 1999's Eph the sampler was playing an increasingly important role in the group's music. Hebden, Ilhan and Jeffers all attended Elliott School in Putney, which has become regarded as a hotbed for musical talent; other notable alumni including Hot Chip, Burial and The xx - all of which members of Fridge have worked with.

Hebden began a solo career in the late 1990s under the name Four Tet while the other two members attended college. Ilhan has also released three solo albums, Homesongs (2004), Love and Other Planets (2006), and Takes (2008) under the name Adem. The band's fifth album (and first in six years), The Sun, was released in June 2007.

The three musicians have also worked on occasion as the backing band for Badly Drawn Boy, and remixed his single Another Pearl.

Fridge also played their first public gig in six years, at Bardens Boudoir in Dalston, London on 9 August 2007. They followed this up with a performance at the 2007 Field Day festival in Victoria Park, London.

5.Hair dryer  is an electromechanical device designed to blow cool or hot air over wet or damp hair, in order to accelerate the evaporation of water particles and dry the hair. Blowdryers allow to better control the shape and style of hair, by accelerating and controlling the formation of temporaryhydrogen bonds inside each strand. These hydrogen bonds are very powerful (allowing for stronger hair shaping than even the sulfur bonds formed bypermanent waving products), but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair.Hairstyles using blowdryers usually have volume and discipline, which can be further improved by the use of styling products and hairbrushes during drying to add tension, hold and lift.

Blowdryers were invented around the end of the 19th century. The first model was created by Alexander Godefroy in his salon in France in 1890. The handheld, household hair-dryer first appeared in 1920. Blowdryers are used both in the beauty salon by professional stylists, and in the average household by consumers.
