The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include:   • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web.   • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web.   • Epinions - Thousands of people contribute to a shared library of product reviews. One of the Web's greatest strengths is its worldwide view a...

Find out how these versatile plugand-play devices can store data Similar in nature to a conventional hard drive, a fl ash drive is a very convenient device capable of not only storing data, but also transferring it quickly between computers and digital devices. A form of solid-state storage (electronic, with no moving parts), fl ash drives are both robust and small enough to fit in your pocket and yet can hold vast quantities of data depending on how great their storage capacity. Flash memory is a type of EEPROM (Electrically Erasable Programmable Read-Only Memory) stored as small blocks. The chunks of data stored using fl ash memory can be erased and re-programmed electronically, making it a quick, effective way of transferring files. When you insert the fl ash drive into the computer’s USB port, the computer automatically detects the device. It then acts like an external hard drive, allowing you to immediately begin storing and retrieving data. The internal workings of a fl ash dr...

Only a few years ago, seeing in 3-D meant peering through a pair of red-and-blue glasses, or trying not to go cross-eyed in front of a page of fuzzy dots. It was great at the time, but 3-D technology has moved on. Scientists know more about how our vision works than ever before, and our computers are more powerful than ever before -- most of us have sophisticated components in our computer that are dedicated to producing realistic graphics. Put those two things together, and you'll see how 3-D graphics have really begun to take off. Most computer users are familiar with 3-D games. Back in the '90s, computer enthusiasts were stunned by the game Castle Wolfenstein 3D, which took place in a maze-like castle. It may have been constructed from blocky tiles, but the castle existed in three dimensions -- you could move forward and backward, or hold down the appropriate key and see your viewpoint spin through 360 degrees. Back then, it was revolutionary and quite amazing. Nowaday...

HOW IS FIBRE OPTIC BROADBAND USHERING IN A NEW ERA OF COMMUNICATION? Remember dial-up internet? Most of us do and it’s not so very long ago that speeds of 56K were considered fast when it came to accessing the delights of the world wide web. And while it may have been fine for checking GeoCities pages and bulletin boards, as our demands and uses of the internet became more complex so higher speeds became more necessary, can you imagine using iTunes or YouTube on a 56K modem? Neither could the service providers who now vie for our attention, trying to find the balance between faster connections and lower prices. Currently the fastest speed on offer in the UK and US and most of Europe lie somewhere between 2MB and 10MB while China, South Korea and Japan lead the way in ‘fibre-to-the-home’ broadband lines. However many western nations such as America, Sweden and Romania are following close behind. Over the next few pages we’ll be explaining fibre optics, the amazing technology behind the n...

Seen by many to be the next stage in the evolution of music distribution and reproduction, Spotify is bringing music to the world of cloud computing.  Spotify is a new application that is available for PC and Mac – along with many modern smartphones – which allows you to stream music from a vast catalogue distributed through the Spotify central hub and sourced from every other Spotify user. To use Spotify you would first need to download the Spotify software from www.spotify.com. Once installed, Spotify looks a lot like other media players such as iTunes, but there is a big difference. With Spotify, you don’t have to download the music in order to listen to it (although this is also possible). Instead you can simply stream it over your internet connection.  To use Spotify you would fi rst need to download the Spotify software from www.spotify.com. Once installed, Spotify looks a lot like other media players such as iTunes, but there is a big difference. With Spotif...

Used increasingly in digital products, how does this technology work? Electronic ink (or electrophoretic ink) consists of millions of microcapsules. Each one contains positively charged white particles and negatively charged black particles, all suspended within a clear fluid. When these microcapsules are subjected to a positive or negative electric field, the corresponding particles rise to the top, becoming visible to the eye and colouring that microcapsule.  eBook reader displays coat electronic ink onto a sheet of plastic film, which in turn is laminated to a layer of circuitry. This circuitry forms a pattern of pixels that can be controlled by the display’s software driver, allowing images and text to be displayed in the form of a traditional page of physical paper.   Electronic ink displays differ from LCDs by utilising ambient light to illuminate pixels, with the rays merely reflecting off their surface. This means they have very low power demand, a...

The Zano flying camera is a great tool for snapping pictures of yourself—and it’s far more sophisticated than a selfie stick. The $300 quadcopter uses a suite of instruments to dodge obstacles while autonomously tracking its subjects whether they’re walking through an office, biking down mountain trails, or even diving off cliffs. Lead engineer Ivan Reedman of Torquing Group advises against underestimating Zano’s abilities: “It’s not just a selfie drone.” REMOTE CONTROL  Zano connects to a user’s smartphone via Wi-Fi. Users can pilot the drone using a virtual joystick on their smartphone screen; they can adjust its altitude via a simple slide bar; and they can instruct the camera to stay fixed or rotate to capture different views. TRACKING OUTDOORS  In follow mode, a user sets the drone to trail the phone at a fixed distance. Outdoors, Zano establishes and sustains its position relative to the phone using GPS, gyroscopes, accelerometers, s...

Traditionally physical systems have been designed by engineers using complex collections of rules and principles. The design process is top-down in nature and begins with a precise specification. This contrasts very strongly with the mechanisms which have produced the extraordinary diversity and sophistication of living creatures. In this case the ‘‘designs’’ are evolved by a process of natural selection. The design starts as a set of instructions encoded in the DNA whose coding regions are first transcribed into RNA in the cell nucleus and then later translated into proteins in the cell cytoplasm. The DNA carries the instructions for building molecules using sequences of amino acids. Eventually after a number of extraordinarily complex and subtle biochemical reactions an entire living organism is created. The survivability of the organism can be seen as a process of assembling a larger system from a number of component parts and then testing the organism in the environment in whi...

INTRODUCTION The word biometrics comes from the Greek words “bios” (life) and “metrikos” (measure). Strictly speaking, it refers to a science involving the statistical analysis of biological characteristics. Thus, we should refer to biometric recognition of people, as those security applications that analyze human characteristics for identity verification or identification. However, we will use the short term “biometrics” to refer to “biometric recognition of people”. MAIN FOCUS OF THE ARTIClE This article presents an overview of the main topics related to biometric security technology, with the central purpose to provide a primer on this subject. Biometrics can offer greater security and convenience than traditional methods for people recognition. Even if we do not want to replace a classic method password or handheld token) by a biometric one, for sure, we are potential users of these systems, which will even be mandatory for new passport models. For this reason, it is u...
