Two of the fastest ways you can connect to the internet these days is with DSL or cable access, so let’s take and explore the argument of dsl verses cable internet and find out which is best. Of course, the choice may be subjective, but there is an ongoing debate of dsl verses cable and which you should choose for your high speed internet needs.
DSL – or digital subscriber line – is run through a regular copper telephone wire that runs from the telephone company into your home just like a telephone line. In fact, if you want dsl service, you can run it straight through your regular telephone line. It loads pages and allows surfing of the internet three to five times faster than a dial-up connection. To get dsl service, you will need a phone line, a dsl modem, and an Ethernet card plus you must be located within a certain distance of the telephone company’s central office.
Cable internet, on the other hand, utilizes the unused broadband portion of the coaxial cable that brings you television service. Most cable companies who have internet access want you to have their television service bundled with internet service or else you will have to pay a higher fee. Like with dsl, you’ll need a special modem – a cable modem – and an Ethernet network card, but there are no distance requirements as with dsl.
So let’s really ask ourselves, dsl verses cable – which is better? In general, most people agree that cable internet is hands-down the winner over dsl. While cable internet is definitely faster and more reliable, the cable lines are shared by area meaning that anyone within a specific area who has cable internet shares the same lines. That can cause a log jam if everyone is using their computer at the same time. So what we are saying is that if there are twenty people on a network and fifteen of them are using their computers at the same time, you may experience some lag as opposed to if only five are using them at the same time.
With cable internet, you are always logged on. With dsl, you are not always signed in and may have to physically connect when you want to go online. Cable is often cheaper than dsl as well. So when we really look at the dsl verses cable debate, it is obvious that cable is the way to go for the most reliable and fastest way to connect to the internet.
The Australian Government in partnership with the National Broadband Network intends to deliver world-class quality and economical Internet service strategies to all Australia. Since the cutting edge Internet broadband innovation was rolled out into the marketplace, millions of homes have effectively switched from ADSL2+ to an NBN Internet plan.
In rural and remote Australian communities, satellite NBN rules supreme. As the more common NBN services such as fixed line and fixed wireless lines are not readily available in backwoods, the National Broadband Network launched two satellites into orbit to send signals to customers residing in the Wilderness. The launch of satellite internet plans in Australia has reduced the digital divide in the country. It has improved the overall online experience of customers residing in the bush.
Here are some advantages of satellite broadband service:
- The use of satellite technology means availability is not limited to a particular area. There are no special requirements as far as installation is required nor do you have to be within reach of an existing cable network (copper or fibre optics)\
- Reliable, high-speed Internet gain access to at all times
- Equipment for NBN satellite broadband consisting of a satellite dish is all supplied by the NBN satellite Internet service. You do not have to buy any additional equipment outside that of what is already being provided by your ISP
NBN satellite Internet is proof of an enhanced communication infrastructure in the nation. Households in rural Australia can now improve their experience online as well as connect better with the world. People in the rural areas now have access to the next generation of web technology and bid goodbye to conventional ADSL which is often slow and unreliable in rural areas of the country.
The digital divide will soon become outdated thanks to the schedule of NBN satellite in remote places of the nation. From interactions, e-commerce, and efficiency, the new technology introduced by NBN via their satellite broadband service will help increase your understanding and keep you abreast on the latest developments in your field of interest.
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.
Fiber optics have a large variety of uses. Most common and widely used in communication systems, fiber optic communication systems have a variety of features that make it superior to the systems that use the traditional copper cables. The use of fiber optics with these systems use a larger information-carrying capacity where they are not hassled with electrical interference and require fewer amplifiers then the copper cable systems. Fiber optic communication systems are installed in large networks of fiber optic bundles all around the world and even under the oceans. Many fiber optic testers are available to provide you with the best fiber optic equipment.
In fiber optic communication systems, lasers are used to transmit messages in numeric code by flashing on and off at high speeds. This code can constitute a voice or an electronic file containing, text, numbers, or illustrations, all by using fiber optics. The light from many lasers are added together onto a single fiber optic enabling thousands of currents of data to pass through a single fiber optic cable at one time. This data will travel through the fiber optics and into interpreting devices to convert the messages back into the form of its original signals. Industries also use fiber optics to measure temperatures, pressure, acceleration and voltage, among an assortment of other uses.
