Computer Tips and Help: Buying a New Computer?

Technology has advanced so much during the past few years that any entry-level computer is going to have more than enough “horsepower” for the average computer user. So the days of being concerned about the size of the hard drive and speed of the processor have pretty much passed into history. RAM (memory) is still vitally important so I would not recommend any new system with less than 512MB. 1GB is even better; and if you’ve got your eyeballs set on the full, bells-and-whistles version of Windows Vista, 2GB will warm the cockles of Mr. Gates’ heart.One topic I always encourage when giving out computer tips and help to shoppers is to purchase locally, if at all possible.

A Brief 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 100 miles.

There are two kinds of fiber optics. The single-mode fiber optic is used for high speed and long distance transmissions because they have extremely tiny cores and they accept light only along the axis of the fibers. Tiny lasers send light directly into the fiber optic where there are low-loss connectors used to join the fibers within the system without substantially degrading the light signal. Then there are multi-mode which have much larger cores and accept light from a variety of angles and can use more types of light sources. Multi-mode fiber optics also use less expensive connectors, but they cannot be used over long distances as with the single-mode fiber optics.

Portable Media Inputs For Computers

Portable media is one of the most popular things that can be used. Whether it is for an MP3 player, a digital camera or something that is just used to transport files around, portable media can be used to easily transfer information from one computer to another. There are numerous portable media inputs to look into.

The most popular of the portable media inputs for computers is the USB input. The Universal Serial Bus input is used to improve plug and play compatibility so that devices can be easily connected to a computer without having to restart the computer or install additional software. Flash drives are especially popular among USB inputs, but various other programs and hardware will use this. This includes MP3 players that use USB connections to connect the player to the computer or portable video players that work in the same way. Hardware for the computers have been using USB inputs too, including computer speakers, monitors and printers.
