But there is more than one way to get broadband to your
computer. You might think you don’t have a choice, but
you do. Everyone in the continental United States has at
least one broadband service provider available. If you live
near a city, you may have a half-dozen broadband service
provider options.

his is going to be great fun. I know computers all
too often have the opposite effect on people, but not
this time. You don’t have to be serious at your computer
all day, and probably the best way to have more fun with
your computer is over a fast broadband connection.
By the time you read this first part of the book, you’ll
know your options, and you’ll have gone through
checklists to help you decide which service provider
delivers what you need. Then your new broadband
connection will help you stop frowning when you sit down
at the computer and start grinning.

ack when sneakers were shoes kids wore to play
in rather than $200 foot-borne status symbols,
one company distilled its advantages into the clearest
advertising slogan ever. If you wore its shoes, you could
“run faster and jump higher.” Doesn’t that capture the
dreams of every kid lacing up sneakers?
Broadband makes your computer run faster and jump
higher. Doesn’t that capture your desires every time you
sit down at the keyboard?
To be honest, broadband Internet access doesn’t make
the computer sitting on your desk process bits faster or
start bouncing around. Computer speed ratings are
derived from a set of variables including processor
speed, the amount and type of computer memory, and
the access ratings of your hard disk.
Broadband does, however, make the Internet and World
Wide Web run faster and jump higher for you and your
computer. Web pages appear in a snap rather than at a
snail’s pace. E-mail’s with photos or other images drop
into your inbox rather than drip forever down your
phone line. With broadband, you will finally realize why
people get excited about Internet radio.
The world of computing will get so much faster, you may
need a seatbelt for your chair. So strap yourself in and
hang on tight.

4 Part I ✦ Determining Which Broadband Is Right for You
Computing Without Interruption
A friend of mine helped a taskforce at Texas Instruments (TI) in the mid-1980s to
study the balance between system response time and user productivity. The
taskforce studied mainframe applications, but the idea remains the same. The
study results showed that after a half second, the user’s concentration broke,
and it took mental effort and time to refocus on the task when the system finally
presented the updated information on the screen.
If you’re the same type of person TI studied nearly 20 years ago, after a half
second of waiting for a Web page to update, you probably lose patience and your
train of thought. The way everything in life has sped up during the last 20 years,
the time now could be less than a half second.
Involved computing sessions demand that screens change as fast as possible. If
they take longer than half a second, as far as your train of thought being
disrupted they can be 4 seconds or 2 minutes. But life on the computer really
runs faster and jumps higher when screens update in a half second or less.
Typical Web Page Download Speeds
An interesting note from broadband provider NTL.com in England shows how long
it takes to download a typical Web page (50 Kbps in the example). Here’s how
they break it down:
✦ 56 Kbps modem: 7.9 seconds
✦ 128 Kbps broadband: 3.5 seconds
✦ 600 Kbps broadband: 0.7 seconds
✦ 1024 Kbps broadband: 0.4 seconds
Nice dovetail with our TI study conclusions, isn’t it? If you get broadband download
speeds of at least 1 Mbps, most pages update in less than a half second.
Now you can justify the cost of broadband to your spouse by saying that faster
speeds mean fewer breaks in concentration, which means you’ll finish on the
computer faster than ever before. (Let me know if your spouse falls for that
rationalization.)
Support files download in a flash
Nothing interrupts your time on the computer more than a pop-up window
demanding you stop what you’re doing to download a file, update, virus
definition, or browser plug-in. Windows users see these computing roadblocks

constantly, but Microsoft can’t be blamed for all the interruptions. Here’s a quick
list of interruption requests on my systems recently:
✦ Windows automatic update files (okay, I can blame Microsoft for this
one)
✦ QuickTime browser plug-in update (from Apple for equal time)
✦ Mozilla plug-in update for Macromedia Flash Player
✦ Real Player update
✦ Norton virus definition files
Each interruption demands that you stop and download a file or files.
Sometimes, for example with a browser plug-in, it takes just a minute or two.
With Microsoft and other operating system files, it can take hours to download a
weekly update package. The same can happen if you download an update to
your browser or one of your multimedia players.
I get more aggravated by the 3-minute interruption and download than the
half-hour ones. When you know it will be 30 minutes, you can start the download
and go do something else. You can take advantage of being forced from your seat
at the computer by wandering around for a few minutes and grabbing a snack.
But when I’m searching for something on the Web and one of those file download
boxes appears and makes me slam to a stop, I curse and glare at the monitor
until I can escape from the trap and go back to my search.
With broadband, however, the downloads arrive in a fraction of the time that
they do with a dial-up connection. What used to be a 3-minute distraction is now
a 30-second annoyance.
Of course, when downloads, such as patches for your operating system estimate
they will take 30 minutes to download over a dial-up line, the broadband user
can laugh. Table 1-1 lists file download times, and you can see that downloading
a file that takes 30 minutes to dribble down a dial-up line takes 5 minutes over a
broadband connection.
Vendors now like you to download a small (under 1MB) file that triggers an
update download of the other 99MBs or whatever. The first time or two I got
fooled by this it really steamed me. I downloaded the 1MB file and installed that,
only to see the newly installed application begin the real work of downloading
for what seemed like 24 hours. With broadband, I get up and start looking for a
snack because the download and installation will probably take 15–20 minutes.
With dialup, my computer is hosed for the evening and I want to threaten the
computer with a baseball bat.
As more companies move toward constant updates for security and operating
system patches, these interruptions will increase. Vendors want users to get
broadband service because it makes it easier on them and because they can
keep stuffing those large updates down the pipe to users.

6 Part I ✦ Determining Which Broadband Is Right for You
If you get one of those annoying “download this update now” windows when you
have broadband, it’s no big deal. It will never be pleasant, but with broadband
the aggravation speeds by quickly.
Applications arrive in a blink
Patches and updates arrive on their schedule and not yours, but the
applications you find and download also take time. Waiting for a file you want,
such as a new spam filter or digital music player, can be as frustrating as waiting
for a complete virus definition file.
Unlike patch and upgrade vendors, developers offering files for download want
your download experience to be quick and painless. Files are often zipped
(compressed) to save time during downloading. You may not even know when
you receive a compressed file because it will often have an .exe extension and
decompress itself automatically when you install it.
Searching for handy utilities, such as those shown in Figure 1-1, changes from
burden to delight when files download quickly. In fact, broadband connections
download files so fast that most of the time you don’t have to save the file and
run it later because you can download and install at the same time.
Figure 1-1: DownLoad.com is one source for new applications that you can
download quickly over broadband.
Table 1-1 contrasts download times for large files using broadband and dial-up
connections.

Do not take these numbers as absolutes or performance guarantees. Many
variables across the Internet influence download times, just like congested
roads influence drive times (yes, the Internet has rush hours). This table
shows estimates based on real-world tests done by the nice folks at NTL.com
in the United Kingdom. But now you see where broadband marketing
companies get their justification for touting broadband as being up to
20 times faster than regular dialup, don’t you?
The application vendors really, really want to persuade customers to
download their programs rather than look for boxes on the store shelves.
Offering applications online is much cheaper for the vendors because they
don’t need to pay for packaging and shipping, and they cut the retailer out of
the equation to save even more money. The vendors say the move provides
fresher programs that include the latest fixes and updates. You will soon get
almost all your programs via the Internet. Transfer speeds and reliability
become even more important when you’re downloading a 150MB office
suite.
How I Will Write Speeds
Different people use different acronyms for speeds, and it can get confusing. Just
when you think you have it right, a typo will mess you up.
Here’s what I will use:
✦ Kbps: Kilobits per second.
✦ KBps: Kilobytes per second
(K for Kilo isn’t an even 1,000. it’s 1,024 because that’s what you get from 2 to
the power of 10.)
✦ Mbps: Megabits per second
✦ MBps: Megabytes per second
(M for Mega isn’t an even 1,000,000, but rather 1,048,576 because that’s what
you get from 2 to the power of 20.)

Know how you almost never use your floppy drive for anything anymore? Before
long, you may use your CD-ROM drive to play music CDs rather than load new
applications. That means downloading rather than installing off a local drive,
and that means you need faster downloading.
Immersive Experiences
Computing without interruption enables you to get more work done. The next
step, for relaxation, is to immerse yourself in some type of entertainment.
Watching a movie in a modern theater moves beyond the uninterrupted
experience into an immersive experience. Sounds come from all around you. The
screen takes up most of your field of sight. Darkness diminishes distractions
from other audience members. When someone in the audience gets and takes a
cell phone call, the movie world is destroyed and you are dropped back into the
modern world where fools and their phones are never parted.
Broadband access transforms using your computer into something at least
closer to an immersive experience, even though you can’t duplicate a theater.
The screen fills most of your vision. Lower prices make a surround speaker
system affordable. And you control whether every cell phone in the area is on
or off.
Modem fans may take exception to this. Wait, they cry, can’t you do everything
listed in the previous paragraph over dialup? Yes and no. You can get the
surround sound speakers, lean close to the monitor, and turn off your cell phone.
What you can’t do, however, is maintain your immersive entertainment world
when the video jerks, stutters, and stops. You can’t immerse yourself in music
recorded at painfully low quality to enable transmission at dial-up speeds. You
can’t convince yourself that ground steak with ketchup is a filet mignon with
b´earnaise sauce.
Beyond entertainment, informational and educational programs take advantage
of computer-based video regularly. Although a short video clip illustrating snake
locomotion would be better on a big screen TV, it provides more valuable
information moving on the computer screen than just a static picture.
Broadband performance can change your computer from something to work on
to a speedy research assistant, from a maker of odd noises to a high-end music
entertainment center, and from a displayer of still pictures to a streaming video
treasure chest. Let me give you some examples.
Streaming audio
Today, finding and listening to interesting music outside the mainstream has
become a do-it-yourself project. If you live in a rural area, you have few radio
stations to choose from. If you live in or near a major city, you have more

stations but not more choices because corporate radio conglomerates now own
multiple stations in every metropolitan area. One owner and one program
manager means mainstream radio plays the same few tunes over and over.
Internet radio and online music sites will change your world if you’re a music
fanatic. If you just like music, you’ll find more sources for more tunes from more
groups than you’ll ever hear on radio. In fact, depending on your music
preferences, you’ll find more music online than you’ll find in the largest music
store in the largest cities. BeSonic, shown in Figure 1-2, will thrill music fans and
particularly fans of European musicians.
Figure 1-2: One of my favorite Internet music tools for finding new groups.
Before I talk about some of the Web sites you should visit to explore the world of
music outside corporate mainstream control, let me give you an idea of what will
appear in the next year or two. Computers will drive the audio entertainment for
many households. This will occur whether you get a broadband connection or
not, but it will be much more fun if you have the fast Internet connection
broadband provides.
Consumer product companies (think Sony, Motorola, Phillips, and the like) now
race to include computers inside their equipment. Computer companies (think
Dell, HP, and Gateway) now race to include consumer products in their catalogs,
all of which connect to their computers. Which side will win? I bet those
consumers interested in linking the Internet into their stereo systems will win

first; then the benefits will slow down for a couple of years until broadband
speeds make downloaded video streams (as in movies) worthwhile. Although
video fans have a strong push underway to liberate the TiVO and make it a
broadband downloading tool rather than a second generation VCR. That will be
interesting to come home to a downloaded movie you ordered from work via a
Web site and had it sent to your home.
Before that happens, however, Hollywood will aggravate almost as many people
as the music industry has by trying ill-considered security measures to keep
honest people from enjoying their movies although doing nothing to stop
large-scale pirating operations. For the next couple of years, spend your money
and attention on the constantly improving world of streaming audio, and you’ll
have plenty of fun.
Lamented Music Site: RIP, MP3.com
The most popular Web music site for 4 years, MP3.com deserves a word of thanks
and a lament for its passing. No site did as much for unknown bands than MP3.com
did. I found many bands playing my favorite type of pop music (ska/punk bands
with horns) by listening to play lists assembled by music fans and posted on
MP3.com. Imagine good friends sitting you down and going through their favorite
cuts of their favorite CDs, and you have the idea.
In 2001, Vivendi Universal, one of the world’s major record companies, bought
MP3.com. Fans worried, but the independent music stayed online. Mainstream
artists from Vivendi and their partners blanketed the front page and much of the
interior advertising, but you could still find great songs, for example: the funniest
rock song I’ve ever heard, “A Slut Named Rachel,” from Skasmopolitan.
At the end of 2003, however, Vivendi sold MP3.com to CNET.com to use in some future music venture. The pleadings of fans worldwide fell on deaf ears as CNET.com
shut down MP3.com and took all music offline despite the offer of several other
Web sites ready to host the music files. A sad day indeed.
Quick hit: Example sites
Listing every streaming audio site on the Internet would take the rest of the book,
and I would still miss some. Here are a few places to go to get started in your
search for new and interesting music, or, if you prefer, old and interesting music.
Although GarageBand.com doesn’t generate the most traffic of all music sites, I
show it in Figure 1-3 because of Apple Computer. Apple released a new music
software package in early 2004 called Garageband and I doubt they worried
about overlapping the established Web site of the same name. The two have
nothing to do with each other except the name confusion.

Figure 1-3: One of the best sites to find new groups and their music.
GarageBand.com does a good job showing the most popular tracks in each main
genre with its Charts pages. For many songs, you can download an MP3 file for
personal use. GarageBand also makes it easy to find CDs for sale by groups; it
shows whether they have live gigs planned (although those don’t seem to be up
to date), and you can leave messages for the artist or group. The site also helps
you find groups that sound like another band.
Music File Formats
Here’s a quick rundown of the most common music file formats. The format type
is usually indicated by the file extension.
✦ .wav: Music file format developed by Microsoft and IBM. Since Windows
95, Microsoft made .wav files the standard for all PC sounds. But the high
fidelity file format requires nearly 10MBs per minute of music.
✦ .aiff: Audio Interchange File Format, the Apple Macintosh version of .wav
files, including the high fidelity and large file size.
✦ .mp3: mp3 is short for MPEG version 3, from the Motion Picture Experts
Group. MP3 is the third generation of a compressed file format that requires
about 1MB per minute of music at nearly the same fidelity as WAV files.

✦ Ogg Vorbis: An open source, royalty free file format similar to MP3 but
not as popular for downloadable music files.
✦ .wma: Windows Media Audio file format, the default to Windows Media
Player. Often used by music services because of embedded digital rights
controls in the file format.
www.SoundClick.com
Perhaps the most popular of the music sites after the unfortunate demise of
MP3.com, SoundClick appears to be chasing that market full tilt. They promise
to create play lists so people can string together their favorite tunes, like
MP3.com did, and they now show the number of plays a tune has gotten.
www.CDBaby.com
Built by a working musician trying to market his own music, CD Baby now
showcases nearly 55,000 CDs, all straight from the artists. You can listen to
tracks CDs, search genres you like, and crank up your PC speakers.
www.IUMA.com
The Internet Underground Music Archive (IUMA) started in 1993 and was one of
the first music sites on the infant WWW. It includes a streaming radio station and
offers multiple tracks from every artist. It offers free MP3 downloads, streams in
MP3 or Real formats, links to CD sales and the like.
www.VitaminiC.com
Connected to IUMA, VitaminiC offers much more international exposure and
song protection by using Windows Media format files.
www.Ampcast.com
Another artist-oriented site, Ampcast started in 1998 and already includes
play lists for gathering your favorites together. The site streams plenty of
tracks, provides downloads, and sells CDs directly to you or recommends other
sites.
www.AcidPlanet.com
One of many sites sponsored by music tool vendors, this Sony-owned site
showcases artists using their products. In this case, Sony now owns Acid Pro
and Sound Forge, among others, and the music posted has almost all been
created or modified by Acid Pro or Sound Forge software.

Not just another music product vendor, BeSonic offers a ton of European groups.
(TerraTec is a German company.) Its excellent Mood Radio page, shown in
Figure 1-2, is at the beginning of this section. The site also provides a visually
cool artists “cube” to help locate groups playing the type of music you want.
Many artists provide a play list of their favorite BeSonic artists, offering another
way to get some interesting connections to different artists.
www.ArtistLaunch.com
This site is pretty self-explanatory, but adds some nice touches with a CD
catalog that lists CDs for sale by genre. The graphics are large enough so you can
actually see the CD cover, an unusual idea for many sites.
www.DMusic.com
This artist promotion site provides an icon beside its songs so you can send a
friend a link to that song. Clever marketing.
Streaming radio Web sites
Internet radio stations may be the only place left to hear interesting new music.
Small groups who self-publish their own CDs or sign with one of the many small
labels need distribution to reach new ears, and corporate-owned radio certainly
won’t give it to them. Next time you complain when hearing the pop vixen de
jour again and again during the day, look to the Internet.
When I searched Google.com for “streaming radio stations,” I received 2,810
listings. Internet radio stations come and go, so there’s no guarantee which of
the 2,810 stations will be up and running if you check them out.
However, here are a few you should give an ear to as you start your own journey:

your display going at full speed. Your computer, whether running an operating

14 Part I ✦ Determining Which Broadband Is Right for You
system from Microsoft (Windows), Apple (OS X), or Linux needs certain
minimum requirements to support streaming video. These aren’t absolutes, but
good guidelines.
Streaming video over the Internet suffers terribly when compared to the
streaming video appliance everyone watches for several hours per day: the TV.
Just about every major corporate content provider (TV networks, movie
studios, music video producers, and infomercial hucksters) wants to make the
Internet, and your computer, a broadcast receiver much like a television.
The world doesn’t really need a new form of TV. And sitting at my desk watching
a video window of maybe 4.5 inches wide by 2.5 inches high when a 37-inch
Toshiba TV sits in the next room strikes me as stupid. So I hope the corporate
content providers don’t manage to turn the Web into more TV stations.
But the race for eyeballs will not stop for me or you. Look for new products over
the next 3 years to link your computer, your broadband connection, and your
HDTV set-top box. Look for appliances that act as the go-betweens for your
wireless home network and your HDTV, including storing video streams for later
viewing. I wonder what the TiVO developers are really up to?
The many geniuses, artists, humorists, and just plain nuts on the Internet
provide enough videos to keep a person mesmerized for years. Any users with a
few dollars a month for a hosting service can offer their own videos to the world.
Be glad they do, because you’ll see some things online you’ll never see on TV,
even if you have full access cable or satellite.
An example of all that’s good and bad about corporate content providers is AOL.
AOL broadband puts streaming video right up front for users. (Its streaming
audio includes a wide range of interesting artists in 175 CD-quality radio stations
as well.) Advertisements abound, of course, but music videos and movie trailers
work well through AOL when you have a broadband connection. Using AOL
broadband also allows multiple members of your family to be online at the same
time. You can enforce parental guidelines that restrict your children’s access to
mature sites as long as you ensure that your children surf the Web through AOL
rather than with Internet Explorer or another browser.
The faster your CPU and the larger your memory, the better. A faster hard disk
always beats a slower one. Most computers built since 1998 include an Ethernet
networking connection that supports 100 Mbps, so you’ll be fine there.
Specification minimums are shown in the following list:
Chapter 11 covers networking in depth.
✦ CPU: Intel Pentium III or AMD Athlon (faster is better)
✦ RAM: 128MB (more is better)
(The information about the previous two items can be found by clicking Control
Panel ➪ System.)

✦ Video: 800 × 600, at least 16-bit depth (more is better)
✦ Sound: Two powered speakers (the ones that came with your PC aren’t
worth much)
✦ Broadband: At least 200 Kbps (faster is better)
Of course, the fastest new computer in the world won’t give you decent
streaming video if you use a dial-up connection. Broadband service on an older
computer beats the streaming audio and video performance of a newer
computer without broadband every time.
Many of the Web sites offering streaming video give warnings about mature
themes. Although the short films usually equate to a movie rated R, some may
go further, so keep an eye on your children. Some sites with movies go much,
much further.
Yes, there are adult movies and pictures on the Internet. In Part III, I’ll explain
how to control who in your home or office sees what, and what the legal
ramifications are for business owners who provide Internet access to their
employees but don’t monitor those same employees when they pipe
“entertainment” videos into the company network.
If you become a big fan of streaming videos on your computer, you might look
for one more accessory to enhance your enjoyment. Go to the bookstore and get
one of those full-page magnifying sheets or at least a big magnifying glass. You’ll
get tired of leaning toward the screen and squinting, I promise.
Quick hit: Example sites
There may be more streaming video sites than streaming radio stations, believe
it or not. But the number includes hundreds or thousands of sites using
streaming video to teach you something. Remote education often includes
streaming video, and there are educational sites for every career or hobby you
can imagine. Figure 1-4 shows the AOL 9.0 Enhanced video section.
In Figure 1-4, I mixed education (a National Geographic clip about volcanoes)
with entertainment (AOL). Few people consider AOL an educational site,
although I used it with my children to take advantage of its parental controls.
Hiding Internet Explorer and forcing the kids to use AOL made it possible for me
to relax when they were on the Internet.
I’m not sure how AOL does it, but the same music videos look better through
AOL than on MTV.com. Perhaps there is something to all AOLs talk about
broadband. And the extra speed makes it easier for my teenaged daughter to
keep a dozen IM windows open while playing Solitaire, watching TV, and talking
on the phone.

provoking, or both. Some of the famous short films that have been e-mailed

Not edgy, unless you think movie trailers for R-rated movies push the
boundaries of good taste. But when you hear about a new movie through the

This used to be edgy, but is now alternately mainstream, corporate, tired,
greedy, or historical. But there are a ton of music videos here, and few things on
the Web benefit more from a broadband connection than music videos.

All major network television Web sites
ABC, CBS, NBC, CNN, and even Fox offer plenty of streaming videos, although
most are from the TV rerun closet. The news sides of the major networks often
include video from other parts of the world not shown on network television
often.
Corporate sites
www.Apple.com/Quicktime
Apple computers didn’t invent multimedia computing, but don’t say that to a
Macintosh fan unless you want to fight. The QuickTime player is a must-have, even
when you already have Windows Media Player and Real Player on your system.
Video Players
Just like with audio players, you have some default video players (Windows Media
Player and Apple’s QuickTime depending on your platform) and some third-party
players. Here are some of the most popular third-party players and Web sites for
download:
✦ RealPlayer (multiple versions): www.real.com
✦ Winamp: www.winamp.com

Communicating Over Broadband
This may seem an odd heading, because broadband is all about sending
information. But information isn’t always communication, and when I think
“communication” I think of a two-way conversation. Many of the broadband sites
listed in the previous section are as two-way as radio and TV.
Some people believe the power of broadband, that of fast communications
across the public network, should be more than just “they broadcast and we
watch.” The beauty of getting a fast Internet connection is that it frees you to do
all sorts of things you couldn’t do before.
Here we hit upon one of the disruptive technologies you hear about sometimes,
when a new technology disrupts established businesses and no one saw it
coming. In the past, voice was analog and data was digital. The two didn’t mix.
But that was the old world, when all telephones had wires attached and all music
played from vinyl records. (Kids, ask your parents to show you a record.)
Voice over broadband
Today, voice conversations can be turned into data streams, just like music can
be turned into digital data on a CD. The process works much like capturing
music for the CD, in fact, because the sounds of the voice are captured, sampled
by the new Internet Protocol (IP) phone, and sent onto the network as digital
data. On the receiving end, the digital data packets are converted from bits back
into sound, just like your CD player does for the music it carries.
The technical term for all this is Voice over IP and the shorthand is VoIP. You
pronounce it just as funny as it looks: vo-eep.
Here’s where things get all tangled up. As I’ll explain in Chapter 3, there
are two primary types of broadband services: over telephone lines owned
and controlled by the telephone companies, and over cable lines owned
and controlled by the cable companies. There are other broadband service options, but they don’t get into the VoIP world yet.

If you’re the cable company, adding VoIP services gives you a wonderful new
feature to sell. Data networking companies like VoIP as well. since it gives them a
wonderful new feature to sell.
Guess who doesn’t like VoIP? The telephone companies. Does VoIP give them a
new product? No, it replaces their most important product. The great value in
Digital Subscriber Line (DSL), the broadband product sold by the telephone
companies, is that it runs over existing telephone wires. The telephone
companies want customers to keep using telephone services running over
telephone lines, not to replace them by running VoIP over cable.
In the long term, VoIP will become more important and more common. The
underlying network technology supporting VoIP makes it much cheaper to carry
voice conversations across data networks than across a pair of telephone wires.
VoIP quality goes up with each new product, and large companies save millions
of dollars by replacing dedicated telephone circuits with VoIP over data
networks for internal calls. One data network connection can carry as many
telephone conversations as a hundred pair of telephone wires, and the tools
used to manage the data network also manage telephone calls running over
those data networks.
The telephone companies, especially the large national carriers with huge
investments in data networks as well as telephone systems, are joining the VoIP
bandwagon. If you can’t beat ’em, join ’em, and it’s better for the telephone
companies to keep their customers than it is for them to keep protecting their
investment in telephone wires.
Individuals and small businesses now have options to buy VoIP telephones and
bypass the telephone companies if they believe the marketing from the cable
companies. Quality keeps going up and the cost keeps going down.
Most small businesses won’t get into VoIP for another year or two. The greatest
value so far is for large companies where the majority of long-distance calling
costs are generated by calls from one employee to another employee. Using
VoIP over existing data networks allows such companies to avoid the long
distance charges from their telecom providers and justify the new VoIP
equipment.
Webcams
News flash: Webcams can be pointed at more than just friendly college girls
asking for your credit card number. Some of the earliest Web entrepreneurs
made a fortune with a cheap camera and a marketing list of voyeurs hiding
behind their monitors. The prurient news value of those webcams
overshadowed all the other ways people used a remote eye.
A few years ago, I interviewed the network manager of a check-cashing service
with branches across several states. This smart guy put a webcam in every check
cashing office. Whenever a security alarm went off in any office, he checked the
webcam before calling the police. It saved him a bundle in false alarm charges.

Tech Bits
If I remember correctly, the first networked webcam watched a coffee
pot in a university in England. People got tired of walking upstairs to find
an empty pot, so they rigged the camera.
Some daycare providers advertise the placement of webcams in every
classroom. Parents use these cameras to check on their children during the day.
Figure 1-5 shows a playpen of a different sort.

Check your local TV station’s news Web site and check out their traffic and
weather webcams. If your local station doesn’t have a good one, check out the
thousands of options at www.earthcam.com/.
Anywhere you have electrical power, you can have a webcam. Every security
camera you see is a webcam, but not viewable by the public. Every traffic
monitoring camera you see watching your downtown streets is a webcam, but
again not open to the public.
Prices for webcams are down to, well, free in some cases. I’ve seen major stores
offer no-name webcams for $25 with a $25 rebate, which is pretty close to free.
Videophones and video IM
First shown to the public at the World’s Fair in 1964, videophones captured the
public’s imagination (and funny faces) from the beginning. Long a staple of every

futuristic movie and television show, videophones have yet to fulfill even a small
portion of their exciting promise.
But once again, the availability of broadband will make videophones work much
better because their big problem in the past has been the limited bandwidth
over telephone lines. The only way to make a videophone at all was to keep the
picture small and the frame rate low, which made no one happy.
Large companies started buying videophones and videoconferencing equipment
years ago to help cut down travel costs. But the costs were high, special network
protocols had to be supported, and only the executives got to play with them.
Those days when only the rich could afford small, jerky images of the person on
the other end of the phone line are gone. Now normal folks can afford
videophones and systems that offer better images than all but the most
expensive equipment a few years ago.
Unlike most competing products, the D-Link i2eye DVC-1100 hooks to your
television via standard video cables and connects to your computer wirelessly.
This makes sense to me. If you want more than one person to be involved on
each end, the TV offers a much better gathering point than a personal computer
(especially if your desk looks like mine).
Prices for electronics like this are tricky to put in a book because prices change
much faster than a book gets reprinted. But the unit shown in Figure 1-6 from

D-Link.com, one of the cost-leaders on the low end, priced this unit not much
more than a video game console. For the first time, a usable videoconferencing
product (I call it more than a videophone because several people can use it)
costs far less than the computer it uses.

For just the webcam but not the videophone feature, the Linksys folks have a

Broadband Gaming
I remember Pong with great fondness. Two lines and a blip ate many of my
quarters. Comparing Pong to modern games gives me the same feeling of
amazement as looking at the first Volkswagen Beetle and a new Ferrari. Yes,
they’re the same thing, more or less, but they’re a long, long way apart.
Today I no longer need to stand next to my gaming partner, each of us holding
the knob on the Pong arcade game unit, to have a shared game experience.
Today I can sit at home and be mercilessly slaughtered by a trigger-happy
10-year-old in Cleveland over the Internet.
If you are a gamer, or are the long-suffering parent of a gamer, you are familiar
with the excitement and addiction awaiting those new to the world of modern
gaming. Gamers push the boundaries of computer technology constantly and
buy the newest, fastest, and most expensive hardware on the market. In a time
where a complete corporate workstation costs less than $2,000, gamers might
spend $3,000 and more on their systems.
Gamers love broadband connections for two primary reasons. First,
downloading takes a fraction of the time it takes with a dial-up connection.
Gamers download new games, new modules for older games, and demos of
upcoming games constantly. Second, a faster network connection means faster
interactive game playing online.
If you have a child gamer and you have broadband, you’ll always know where he
(perhaps a stereotype, but the gamer is usually male) is. He will be at home,
playing over the Internet.
Game play requirements
Besides the most expensive PC systems on the market, what do game players
need? More speed, always more speed. Latency, the technical term for the time
lag between when a command is given and the results take effect, is the enemy of
gamers everywhere.
The Internet, as you will learn later, consists of networks linked to networks
linked to networks. It is, technically, a network of networks.

Every connection between networks is a potential bottleneck. The good thing
about broadband service providers is that they tend to be the large companies
and their customer networks have direct connections to other large customer
networks. The Internet backbone is the highest level of network where all the
largest networks connect.
Some service providers offer a special package for game players. This includes
an extra IP network address so gamers can be online playing without blocking
another family member on another computer from an Internet connection. This
type of arrangement used to be special, but now many service providers
automatically provide a network router for connecting more than one computer
in the home or office to the Internet. But check with your service provider to
ensure it supports a game console connection if that’s the platform of choice for
your gamer.
Using a network router between your computer and the modem provided by the
service provider offers a great troubleshooting option: resetting the cable/DSL
modem. When the going gets gummy, resetting the broadband modem (unplug
it, wait for 60 seconds, then plug it in again) forces a new connection. Just like a
telephone call sometimes has static, a network connection can get the digital
equivalent of static. Resetting the broadband modem helps clear that problem,
making a separate broadband modem an important piece of gear for gamers.
More detailed information on game-specific configuration of routers, firewalls, and proxies await you in Chapter 11. If you don’t know what
routers, firewalls, or proxies are, but fear you need them, don’t worry, I’ve
got your back.
Wrapping yourself in the game world
Few technologies are more engrossing and exclusionary than a good game.
When I first saw the groundbreaking Wolfenstein 3D in 1992, the parts that
scared me the most were the sound effects. The large steel doors that opened
and closed in Castle Wolfenstein echoed with a surround sound that made it
sound like they were opening behind me. That they managed that effect with the
cheap PC soundcards and speakers at the time still surprises me.
Gamers spend hundreds of dollars on video cards to replace the ones you and I
happily use, in order to get the highest resolution and the fastest screen-drawing
times. Check out some of the game sites listed in the next section, and you will
be amazed at the realism and depth of the game environment. You don’t have to
sign up for a paid service just to view screenshots and movies taken from actual
game play, and those will be enough to show you that game effects now equal
movie special effects.
Developers work with hardware designers to try and get physical impact into
games. Even inexpensive handheld controllers vibrate to warn the players. Over
the years, companies sold packs to strap on the players’ backs with speakers
inside to shake them up and special chairs with surround sound and quaking

cushions to reflect driving over rough ground. These expensive options don’t
tend to stay on the market for long, but new ones always appear.
Parents who are afraid that their gamer children exercise only their thumbs may
check into some of the new interactive game additions. A few companies are
selling cameras that mount on the TV and capture physical player movements
and translate those into character moves in the game. Let your child physically
flail around fighting some demons and they’ll get into shape again. Somehow, I
doubt the chance for physical workout will attract too many gamers.
For me, ever since the first time I saw (and heard those steel doors in Castle
Wolfenstein), sound provides the best immersion tool. Broadband offers higher
quality music than dialup by a considerable margin. The difference in music is
about the same as the difference between a cheap AM transistor radio and a
modern FM home stereo.
Get a better sound card, and get better speakers. You can spend as much on
surround-sound speakers for your computer as you can for your home theater.
Although I don’t advocate that outlay, moving up to a five-speaker system for at
least $100 will make a huge sonic difference. Even the game consoles like
PlayStation and X-Box support surround-sound speaker systems.
Are games intruding into everyday life? Radio@AOL has a channel with nothing
but the music from the Final Fantasy game series. Even when gamers can’t play,
they can keep their ears in the game.
The most popular games
Warning, if you’re new to the gaming world, popular online games take money.
You must subscribe to play. And you thought only pornography made money on
the Internet.
The choice of broadband type and other connection details will have no effect
on your choice of games. Gamers play certain games for a variety of reasons,
some of them innocent and some no doubt based in horrible neuroses foisted
upon them by bad parenting. When your kids tell you that, explain to them all
the violence in the game world has rotted their brains and they need to take up
tennis to get fresh air and exercise. Don’t let them tell you Topspin on the X-Box
is the same as real tennis.
Your gamer will, when you hook up to broadband, begin playing multiplayer
games across the Internet. These go by a variety of acronyms made from some
set of the words Massive Online Player Universe and the like. Entire worlds
exist for the big games, including people, places, weapons, and monsters never
seen in real life (thank goodness, if you’ve seen some of those weapons and
monsters).
There are too many games to list them all. Understand that even a relatively
unpopular game may have a hundred thousand fans playing the game online
now and then.
