10 most important gadgets

This is not grandiose inventions and breakthroughs in science. This is not a discovery, which changed the perception of the outside world. But these devices and technologies behind them have become the embodiment of the revolutionary concepts of interaction with the world of information in the field of entertainment and communications. They will remain in the history of the electronics industry as the original icon, the point of changing trends indicated the turning points of the era of information technology. Top-10,

1. Sony Walkman

It is believed that this player marked the advent of the concept of portable music in the broad masses. First cassette player appeared in 1978 thanks to the engineer Nobitoshi Kiara (Nobutoshi Kihara). Supposedly one of the company wanted to be able to listen to musical operas in the long transoceanic Perel emax, and the result of the works was subordinate Walkman, released on the market as a model TPS-L2, in 1979, and in many countries under the name Soundabout. Initially the device was equipped with two headphone jacks, but later by the decision, refused. With the proliferation of CD and MP3 audio cassette players lost its popularity, but Sony still continues to deliver some models of Walkman in individual countries.

2. ASUS Eee PC

According to ASUS, «Eee» stands for «Easy to learn, Easy to play and Easy to work» ( «Easy to learn, easy to play and easy to work”). The first model netbook, which was the progenitor of a new segment of portable computers, appeared in 2007. Eee PC 2G Surf (700) was equipped with 7 “screen with 800 x 480 and LED-backlit, 2-GB SSD, 800-MHz processor, Intel Celeron-M ULV, 512 MB RAM, GMA 900 integrated graphics and running on Xandros based on Linux. For two years, completing the set of new line of products, including the Windows XP, hard drive to 250 GB, “atomic” CPU and screen with a diagonal of 10.2 “.

3. iPod

iPod came in October 2001 and, of course, was not the first MP3-player. Also, initially it only connect to a Mac, the cost was $ 400. But with the revision of Apple’s development strategy of the product line, introducing support for conventional PCs and the USB connector device has become immensely popular. By September 2009 around the world have sold over 220 million iPod. The series includes models of iPod Shuffle, iPod Nano, iPod Classic and iPod Touch. iPod Shuffle has no display, container carriers, which serve as flash memory and hard drives, ranging in different generations of iPod from 512 MB to 160 GB.

4. GPS-navigators

Global Positioning System is undoubtedly one of the most popular technology today, as the corresponding user devices. The first tests were carried out as early as 1970, today serves 31 GPS satellites. To determine the coordinates of GPS-receiver uses signals from 4 satellites, the location is calculated by measuring the time delay distribution. The accuracy of the system depending on weather conditions ranged from 5 to 15 meters. Because GPS is controlled by the U.S., a country on the other side of the Atlantic are making efforts to develop its own satellite navigation network. Europe is developing a project Galileo, Russia – GLONASS. With the development of technologies for the production of electronics became possible to embed modules reception of GPS signals to mobile phones and other portable multifunction devices.

5. SMS

Because the value of mobile phones can be no doubt, is to assess SMS – not just the short message service, but a phenomenon of the information world, with its inherent characteristics, culture, and the ability to solve many problems of everyday life. For example, fans of communication through the mobile services may be “professional” disease, championships are held on typing speed (the last world record – 160 characters of 41,52 sec), and payment services via SMS has become a familiar tool of calculation. A system to send text messages has been tested in the UK in 1992, although as a standard for mobile communications proposed as early as 1985. In 2008, sent over 4 trillion SMS.

6. Digital Camera

Digital cameras have eliminated many of the shortcomings of film precursors and the consumer “shoot cameras, including concerns about the failure of the remaining stock of images and film, calculated at 24 or 36 frames. With a simple camera and computer, anyone can try their hand at the art of transferring their own view of the world through photography. The basis of this type of devices – a sensitive matrix, made by technique of CCD, CMOS or Live-MOS. Digital images made possible by the proposed the idea of a CCD (charge-coupled devices), George Smith (George Smith), and Willard Boyle (Willard Boyle), who in 2009 received a Nobel Prize for his discovery. In 1981 he was released on SLR camera Sony Mavica with a resolution of 0.28 megapixel, images are stored on magnetic disk. Barrier in 1 megapixel overcome in 1997, the device FujiFilm DS-300.

7. Nintendo Game Boy

Appearing for the first time in 1989, the handheld console Game Boy went quickly to the dominant level among similar devices and stayed there for a decade. Monopoly tried to shake the Game Gear from SEGA and SNK Neo Geo Pocket, but the products Nintendo was out of competition. The console was equipped with 4-MHz processor, a screen with a resolution of 160 x 144, 8-kB main memory and graphics memory of a similar size. In 1998, the Game Boy Color came out with a color screen (56 colors are displayed simultaneously), and in 2001 the stores were replenished Game Boy Advance with color display (512 colors at once, a resolution of 240 x 160) and 16-MHz CPU. As of August 2008 had sold more than 118 million Game Boy and Game Boy Color.

8. USB-stick

Music, movies, documents, software, operating systems, backup copies of files – all individually and collectively transferred to compact devices with flash memory. Gained popularity in the 2000’s, along with lower prices and increase in the amount of memory – a trend that continues to this day. Well-known drawback of such drives is the limited number of write cycles, the same feature is inherent in SSD. Flash memory offer employees of Toshiba in 1984, and the first chip nonvolatile memory such as NOR appeared in 1988, the efforts of Intel. Widespread currently NAND chips are also the brainchild »Toshiba.

9. ADSL Modem

Thanks to technology xDSL high-speed Internet moved from the category of privileges accessible means of entertainment, the solution of many problems and business development. Modification of ADSL (Asymmetric Digital Subscriber Line – asymmetric digital subscriber line) appeared in the 1990’s and implements data transmission over normal telephone lines. Channel Capacity divided asymmetrically between traffic – speed input (available bandwidth from 138 kHz to 1104 kHz) exceeds the rate for outbound (25-138 kHz). ADSL2 + can theoretically provide the first case up to 24 Mbps, the second – up to 3.5 Mbps.

10. iPhone

Apple released the first iPhone in June 2007. The device, which has no physical keyboard, changed the approach to the creation of mobile phones from manufacturers and their perception of consumers. A year later, iPhone 3G model with support for GPS and A-GPS, in 2009 – iPhone 3GS with the new processor Samsung S5PC100, 256 MB RAM and a 3-megapixel camera. Through an online service App Store, users can get access to thousands of applications for the iPhone. By the second quarter of 2009 around the world have sold over 21 million units of this “apple” product.
