Navino launched its search engine gateway service recently. For most of the Internet surfers, search engine gateway is a pretty new concept compared with meta search engine or multi search engine. Put it in simple, it is a web service, which can let you search the best information from the best content providers in one website.
When we try to find information everyday, most of us might go to Google.com. Yes, it’s true. Most of the time, Google works well. But does Google return the best information? I guess you would agree that the search engine’s ranking algorithm could only give a good answer, but not the best. Well, you may ask, where can I get the BEST? The best weather information? The best book information? The best price for your favorite mp3 player? The short answer is from the brain, from the hand picked information. Therefore, Navino’s editors and their users give out that the best weather website is weather.com, the best book website is amazon.com and the best price information is froogle.
Besides best hand picked information resources, Navino also provide the search engine gateway technology. Using this technology, you can search all the best website at Navino. All you need to do is to add a unique search name before your searching keywords.
For example, if you want to search New York’s weather, you can search with ‘weather New York’ and you will be forwarded to weather.com with the keyword ‘New York’. If you… Read the rest

Wireless networks work using radio waves instead of wires to transmit data between computers. That’s the simple version. If you’re curious to know what’s going on in more detail, then it’s all explained in this article.
Ones and Zeros.
I’m sure you know that computers transmit data digitally, using binary: ones and zeros. This is a way of communicating that translates very well to radio waves, since the computer can transmit ones and zeros as different kinds of beep. These beeps are so fast that they’re outside a human’s hearing range — radio waves that you can’t hear are, in fact, all around you all the time. That doesn’t stop a computer from using them, though.
Morse Code.
The way it works is a lot like Morse code. You probably already know that Morse code is a way of representing the alphabet so that it can be transmitted over radio using a dot (short beep) and a dash (long dash). It was used manually for years, and became a great way of getting information from one place to another with the invention of the telegraph. More importantly for this example, though, it is a binary system, just like a computer’s ones and zeros.
You might think of wireless networking, then, as being like Morse code for computers. You plug a combined radio receiver and transmitter in, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from one place… Read the rest

Fiber cables form one of the most important parts of the networking industry today. Fiber cables are composed of one or more transparent optical fibers enclosed in a protective covering and strength members. Fiber cables are used to transmit data by the mode of light. Various types of fiber cables available are multimode duplex fiber cables, single mode simplex fiber cables, single mode duplex fiber cables, and plastic optical fiber cables.
There are many fiber optic cable manufacturers who manufacture full line of fiber cables in both single mode and multi-mode, simples, duplex and multi-strand. Several manufacturers provide low cost, quick-turn, high volume fiber cables and fiber cable assembly solutions.
Cables with complete assembly of fibers, strength members and jacket refer to fiber cables. These fiber cables come in variety of forms depending upon their usability and place of use. It is important to identify the exact requirement of fiber cables whether they would be easy to install, splice or terminate, etc. This is necessary as it ultimately decides the cost of installing the fiber cables.
Fiber cables are required to protect fibers from external hazards. Thus before installing the fiber cables one should always assess the place of installation of fiber cables. Fiber cables required inside the house or a building are not exposed too much of hazardous condition thus simpler form and not-so-tough fiber cables can be used for installation. But if the fiber cables are to be installed for longer distances and outside premises then… Read the rest
