Introduction Think about how you access the Internet today. There are basically three different options: * Broadband access - In your home, you have either a DSL or cable modem. At the office, your company may be using a T1 or a T3 line. * WiFi access - In your home, you may have set up a WiFi router that lets you surf the Web while you lounge with your laptop. On the road, you can find WiFi hot spots in restaurants, hotels, coffee shops and libraries. * Dial-up access - If you are still using dial-up, chances are that either broadband access is not available, or you think that broadband access is too expensive. The main problems with broadband access are that it is pretty expensive and it doesn't reach all areas. The main problem with WiFi access is that hot spots are very small, so coverage is sparse. What if there were a new technology that solved all of these problems? This new technology would provide: * The high speed of broadband service * Wireless rather...

Introduction In most of the world, camcorders, or video camera-recorders, have been a familiar sight for nearly 20 years. People take them everywhere: to school plays, sports events, family reunions and even births! When you go to a popular tourist spot, you are surrounded by them. Camcorders have really taken hold in the United States, Japan and many other countries around the world because they are an extremely useful piece of technology that you can own for under $300 (or more than $100,000). How can such a small device do so much? Particularly for anyone born before the 1980s, it's simply amazing that quality video cameras are now readily available as consumer items, and that they're so easy to use. Camcorders have been a familiar sight for nearly 20 years. The Basics A typical analog camcorder contains two basic parts: * A camera section, consisting of a CCD, lens and motors to handle the zoom, focus and aperture * A VCR section, in which a ...

Introduction Nearly every desktop computer and server in use today contains one or more hard-disk drives. Every mainframe and supercomputer is normally connected to hundreds of them. You can even find VCR-type devices and camcorders that use hard disks instead of tape. These billions of hard disks do one thing well -- they store changing digital information in a relatively permanent form. They give computers the ability to remember things when the power goes out. In this article, we'll take apart a hard disk so that you can see what's inside, and also discuss how they organize the gigabytes of information they hold in files! Hard disks store digital information in a relatively permanent form. Hard Disk Basics Hard disks were invented in the 1950s. They started as large disks up to 20 inches in diameter holding just a few megabytes. They were originally called "fixed disks" or "Winchesters" (a code name used for a popular IBM product). They later became known...

Introduction When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols. There are lots of different ways that electronic devices can connect to one another. For example: * ­C­­omponent cables * Electrical wires * Ethernet cables * ­WiFi * Infrared signals The art of connecting things is becoming more and more complex every day. In this article, we will look at a method of connecting devices, called Bluetooth, that can streamline the process. A Bluetooth connection is wireless and automatic, and it has a number of interesting features that can simplify our daily lives. ­The Problem When any two devices need to talk to each other, they have to agree on a number of points before the conversation can begin...
