Broadband DSL and Dial-up The
Ability to reach the World. What is broadband? The Internet is getting more elaborate day by day. Web pages are swarming with animation, downloadable movies and music abound, and even e-mails from Grandma and Grandpa can contain pictures or even home video clips. The phone modems used by most people to get Internet access to date have reached the limits of their performance, necessitating new technologies to allow users to surf the Internet without having to wait minutes (or hours) for a page or file to download. This new technology is collectively known as broadband. Broadband comprise a variety of different systems, but they all have one major goal: to increase the rate a user can send and receive data, and thus make the Internet (and other online activities, like videoconferencing) easier and faster to use. For the uninitiated, broadband is a bewildering array of acronyms and technical babble, most of which isn't really all that important to someone who's just trying to get a good deal on fast Internet access. Below we'll explain a few of the more important bits of jargon, but for the most part, we'll concentrate on making sure that you know exactly why you need to upgrade to a broadband service to view Web pages, play games, listen to music or streaming video's designed or developed by ROBBIE 19 Publishing Company on the web today. We often update our software and hardware in an effort to stay up with the latest broswers, technology and most of all our clients needs. What can broadband do for you? If you access the Internet from home, you've probably been using what's known as a dialup connection; in other words, you dial a telephone number on your computer, hear a series of weird sounds, and end up surfing the Internet about a minute later. Sometimes you get busy signals, or the connection speed suddenly drops to a snail's pace, or somebody in the house picks up the phone and cuts your connection right in the middle of an important download. Depending on your service provider, you might even have to carefully limit the amount of time you spend online, or else pay extra hourly fees. The first advantage of broadband is that it generally avoids the hassles associated with dialup connections. With most forms of broadband, you can surf the 'net freely, without worrying about tying up your phone line or using up a precious allotment of hours. The second (and for many, the most important) advantage of broadband is speed: lots of it. If you've sat around twiddling your thumbs while waiting for a web page to download, you know how annoying a slow connection is. With broadband, those aggravations are reduced or even eliminated. Not only will web surfing be faster in general, allowing you to hop from web page to web page almost as fast as you can click your mouse, but the speed of broadband opens up a host of other possibilities for both home and business users. Streaming media are movies and music that can be viewed on your computer without first saving them to your hard drive, much like the way you've always been able to watch a television show without having to record it on a VCR first. Downloading a streaming video on a dialup connection is akin to picking up a faint TV signal using a coat hangar as an antenna; the signal can fade in and out, and even at its best, it's not great. With a broadband connection, a streaming video will come in fast and steady, with much better video quality. Computer gamers can play online against opponents around the world, without lag or slowdown, and without the worry that a family member's important phone call will interrupt a vital shoot-em-up tournament. Some broadband connections even allow video conferencing, similar to the videophones that every science fiction movie character seems to have. While video conferencing is now possible using multiple ISDN lines and expensive equipment, the expense is far out of the budget of most residential and small-business users; the speed and cost of broadband brings this once-rare capability within reach of the average consumer. |

In the computer industry, connection speed is measured in "bits
per second" (bps), and space is measured in "bytes". You
might say "I downloaded a 5 megabyte file at a rate of 3 kilobits
per second."

Note about wireless: the speed of wireless broadband depends on how your provider is set up; in many cases, wireless speed is closer to DSL, and in some cases, it's as slow as basic ISDN. Where's the Catch? Actually, there really isn't one, at least not if you shop carefully and know what you're getting. The major concern for most prospective broadband buyers is cost; logically, if your speed is going to increase tenfold, shouldn't the price increase at the same rate? Luckily for your pocketbook, that's not the case. The monthly fee for most residential broadband services hovers right around $50, which isn't much more than the combined cost of dialup service and a second phone line. There are often extra features available for an additional fee, but these aren't necessary for most home users; such features are often geared toward businesses, and are priced accordingly. The main "hidden cost" of broadband comes from the initial set-up. Buying the necessary hardware and paying someone to get it working can sometimes add up to several hundred dollars. However, competition is forcing many broadband providers to offer attractive discounts and promotions. These days, it's not uncommon to find offers of free hardware, free installation, or even easy self-install options. There are other concerns to address, too, but don't worry; the final verdict is pretty good. Availability: Installation Ease: Your computer doesn't need to be the latest and greatest to run broadband; most computers sold within the last five years should be quite capable of supporting a broadband connection. You'll definitely want to check your system specifications, though, just to be sure. If you're not sure what the differences are between USB, PCI and a loaf of sliced bread, most broadband providers and support sites (including this one) have customer service reps as well as quick online tutorials that will get you up to speed on the basic attributes of your computer (hint: ignore the loaf of bread). Reliability:
Don't let this scare you off, though; when properly set up and used, broadband is just as safe (or safer) than talking to someone on the phone. Most businesses use a kind of software program called a firewall to protect their computers; much like a physical firewall, a computer firewall is a sturdy barrier against outside attack. Firewall software is available for home use, and in fact, many providers include or suggest specific firewalls when you install their software. Take some time to learn about security requirements and protection; a few hours during the learning stages can save you a lot of headaches later on. How many kinds of broadband are there, anyway? There are currently five major types of broadband service. Each one has its own advantages and disadvantages, and some are notably better overall than others. We'll cover each one briefly: Cable Modem: The main disadvantage of cable is that the speed of the system is dependent on the number of people who are online at the same time; if many people in your neighborhood are using their cable modems at once, your connection speed may drop considerably. Cable modem performance can undergo significant fluctuations; at its best, it's the fastest of all consumer-level broadband services, but at its worst, it's almost as slow as a dialup service. Cable modem service is a good choice if there aren't too many other cable modem users in your area, and you want a system that's easy to set up and maintain. DSL:
The main disadvantage of DSL is that its speed is dependent on your physical distance from the phone company's nearest central switch (known as a Central Office); the farther you are from the switch, the slower your average connection speed will be. Your home or business will have to pass a loop qualification test run by your phone company before you can have DSL installed. Also, DSL setup can be complex; in many cases, separate visits from the broadband provider and your phone company will be required. DSL is a good choice if you are close to the phone company's central switch, if your phone lines are up to spec, and you need a reliable high-speed connection. While it's not yet as widely available as cable modem service, DSL is often a viable alternative and may sometimes even be preferable to cable modem. Satellite: There are downsides, though. The performance of a satellite broadband connection can be degraded by bad weather, local interference, or a misaligned dish. Also, because of the way the satellite data transfer works, satellite service is not well suited to applications that require constant transmission of small data packets; these include online gaming, web page hosting, video conferencing, and multiple small file downloads. Some satellite providers who have not upgraded to two-way satellite communication equipment also require the use of a phone modem connection to send data to the broadband provider; this results in additional costs and slower speed. However, the monthly costs are usually reasonable, the equipment is often discounted or free, and most importantly, you can get satellite almost anywhere. Satellite isn't as fast or reliable as DSL or cable, but if it's your only choice, it's definitely better than dialup. . ISDN: ISDN is slower than the other, newer forms of broadband. Still, ISDN is often the only choice for many users whose cable and phone companies haven't yet (or aren't planning to) implement local cable or DSL service. ISDN also offers some advantages over satellite (the other widely-available broadband choice). For instance, ISDN is good for use by networked computers, online gamers, and web-page hosts; these are areas in which satellite's performance lags. ISDN lines are often used by businesses because their speed is reliable and constant; ISDN speed doesn't fluctuate as a result of bad weather, location, or cable modem activity in nearby buildings. ISDN hardware is often complex and not easy for the novice to set up, and even basic ISDN service is more expensive than other forms of broadband. However, if neither cable nor DSL are available or suitable, ISDN is a viable, if expensive, way to get a broadband connection.
