What is Barcode Barcodes encode numeric or textual information in a printable, machine-readable form. The use of barcodes can significantly reduce cost of warehouse management and inventory. Two main forms of barcodes exist today: Linear or normal barcodes encode data over a horizontal stretch of space or one dimension. This kind of barcode typically encodes between four and forty digits or characters. So called area codes encode data in two dimensions, resulting in much higher density which allows for up to three thousand characters to be encoded. Most linear barcode types will only encode numbers or digits. Two notable exceptions are Code 39 and Code 128 which can also encode alphanumeric characters like letters. Two dimensional area codes usually encode numbers, letters and special characters. The most common linear barcode type is Code EAN which is used to encode article numbers in retail. It's used throughout the world with the notable exception of the USA which uses a...

Download Accelerator Software Provides a Faster Download Over half of all households that connect to the Internet have a broadband connection these days, mostly cable or DSL. Which means the other half does not and still uses dial-up. Modems are much faster than they used to be in the early days of computing, but today's websites are larger and require a lot of bandwidth to load quickly. To make matters worse for those on slower connections, even simple software updates are now often dozens of megabytes and can take a long time to download. What it all means is that modem users need a break! Fortunately, there are things that can be done to make a connection faster. You see, the operating system software on today's computers is not optimized for fast downloads. Microsoft's primary goal is simply to make sure Windows works with all the different hardware out there. Compatibility is important, of course, but it can be frustrating when things just don't work as well ...

Introduction To Fiber Optics Technology Understanding how fiber optics are made and function for uses in everyday life is an intriguing work of art combined with science. Fiber optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibers enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. Fiber optics have a highly transparent core of glass, or plastic encircled by a covering called "cladding". Light is stimulated through a source on one end of the fiber optic and as the light travels through the tube, the cladding is there to keep it all inside. A bundle of fiber optics may be bent or twisted without distorting the image, as the cladding is designed to reflect these lighting images from inside the surface. This fiber optic light source can carry light over mass distances, ranging from a few inches to over 1...
