Answers

1. The answer is True. In fact, it is the tremendous savings of up to 80% off traditional phone calling that makes VoIP attractive to consumers and businesses. The only equipment needed for VoIP is your PC and a microphone (if one is not built into your PC). Beware of VoIP service providers that require you to purchase additional equipment and/or sign contracts.

The newest techno gadget, which is reshaping the way teenagers interact is the Digital Picture Camera 3G Cell Phone. As more and more people have these and as higher bandwidth and video compression technologies are introduced we will see a whole new realm of communication. As people communicate on cell phones with video and pictures we will see a decrease in crime.

Because the criminals will realize they will be caught on phone, by a number of possible passers by if they try any criminal activities. The eyes and ears of the society will evolve in scope and with that we will see random acts of theft, violence decrease. Of course there will always be the smart criminal who tries to figure out in advance a specific plan to evade detection, although the common criminality we generally see will surely render more favorable crime statistics.

Those areas where people have more cash flow such as the Suburbs of large cities or in the Downtown techno sector crowds we will see lessened crime. Although the will then be a "Criminal Divide" in areas where less techno savvy people reside.

Get started creating web pages using text files and HTML code! This article is a continuation of HTML Explained: Part 1, which gives a general overview of HTML. Here, we’re going to get into the nitty gritty of the code itself. Once you see how simple it really is, you should RUN, not walk to the nearest bookstore and grab your own copy of a handy HTML manual. All right, let’s begin.

In viewing the source of web pages, you may have noticed a lot of these things: < >. They’re called HTML tags, and they’re what the computer uses to interpret the HTML code.

NOTE: in this article I had to add spaces to all of my HTML tags so that I could display them without actually having them work. There are two HTML tricks to actually “shutting off” HTML tags, but neither of them function properly in this submission box.

The HTML tags shown here will display like so: < FAKE TAG > but in reality you’re supposed to type them like so:

Used laptop computers are everywhere these days. How can you sift through the mass of available used laptop computers to narrow your search down to the right laptop for you? This is the second part of a series of articles designed to give you a few suggestions for your next purchase.

Assuming you’ve done the visual inspection mentioned in part one, you’re ready to power up the laptop and do some more digging.

Laptop Operating System

Does the laptop you’re looking at come with an operating system? If not, it could be difficult for you to fully test the operation of the laptop. One good alternative to a built in operating system is to download and burn a copy of Knoppix. Knoppix is a linux operating system that runs off the CD-ROM drive instead of the hard drive. This allows you to test the laptop even if it doesn’t have an operating system installed. You can find Knoppix at www.knoppix.com

Quick Power Up Inspection

The Internet, as most people know it, is history.

It just seems like yesterday the Internet was just one big mass of wires and cables; a glorified file sharing warehouse with more than a few too many lines sticking out. One enormous LAN party that just got out of hand, causing a ruckus and spilling out down the block and around the world; creating too many millionaires for no good reason and causing too many sleepless nights surfing the neon pink.

The Internet quietly crept into every facet of our lives… no subject or topic was left unexplored in this binary medium. Suddenly, there it was, the authority on everything. Our lives encyclopedia-ed to death by bits and bites.

But the Internet has always been perceived as a connected medium; tied together by cables, servers and networks. Until now that is, because now everything has changed. And it’s about time, the Internet has been tied to the ground for far too long, it’s time for liberation. Independence Day. Bring it on!

The Internet is going Wireless — for real this time.

Want to save money while promoting your web-based business? Of course you do. Here’s some advice on the matter, from a freelance copywriter who knows: it pays to learn the basics of HTML.

If you’re like me (stubborn), you’ve probably been dodging HTML for many years. All that code mushed together… it’s distressing to look at! But here’s the thing: HTML is your friend. He might be ugly, but he’s a good guy to have on your side.

Once you get a basic understanding of how HTML works, the gibberish starts to make sense. And that’s when you’ll realize how easy it is to create web pages for your own business without having to 1. pay a designer thousands of dollars, or 2. purchase one of those expensive web design programs.

Let’s start with a general explanation. HTML stands for Hyper Text Markup Language. It’s the basis for every single design element you see on a web page: layout, copy, image placement, links, music, animation, etc. People who design their sites using fancy web page creators with buttons and copy/paste features are merely controlling the HTML code via the program’s graphic overlay. Underneath it all, the code’s still there in its pure form. You can see it if you go to a webpage and then click View>Source from the top menu.

Used laptop computers are everywhere these days. How can you sift through the mass of available used laptop computers to narrow your search down to the right laptop for you? Here are a few suggestions to keep in mind.

Buy from a reputable dealer

It can be tempting to pick up your local classifieds and simply choose the lowest price laptop in the newspaper and buy it from whomever. This is a mistake. Less headache and aggravation will result by buying from a reputable dealer. If something goes wrong with it right after you buy it, you’ll at least have some recourse.

Quick Visual Inspection: Looking for signs of damage

One of the most common ways a laptop is damaged is by dropping it on a hard surface. Look for cracks around the corners of the laptop. You should also look for any chipped plastic around the LCD Screen.

Make sure the hinges of the LCD Screen are in good shape and aren’t cracked or separating from the body of the laptop. This damage can result when someone opens the screen too far. It can also be the result of being dropped.

The titanic developments in new technology have radically changed the way we watch TV and movies at home. Gone are the days when the TV set was a box in the corner with a 20in screen and a tinny speaker. Now most of us prefer to watch movies and sports casts on a widescreen that’s at least 28in from corner to corner.

If you are a fan of home theater then that screen will almost certainly be bigger and be accompanied by a surround sound speaker system to maximise the aural effect and immerse you in the action. As technology improves and equipment becomes cheaper, more and more people will have high definition TVs and home theater set- ups.

However, if Sony has its way, we’ll all be enjoying a completely different movie- watching experience, on a 2inch mobile phone screen. Sony wants to see an iTunes- style download service for movies so we can download them and watch them on the move. Would you watch a film on a cellphone? I wouldn’t.

While most small businesses really do need to find a good local computer consulting business to take care of their computer problems, there are some computer problems that are simple enough for even a technophobe to handle. At Computer Consulting 101, we’ve found there’s one very simple piece of advice that often doesn’t get communicated to non-technical small business end users: When in doubt, reboot first.

Seriously, while it may sound tremendously simple, end users often overlook it during typical computer panic attacks.

Anytime you’re about to consider an issue a real IT support problem and call your computer consulting vendor, always reboot first.

First, exit out of whatever files and programs that you’re working on. Then, run through a Shutdown and Restart sequence to reboot your computer.

If you suspect your computer problem involves something hardware-related, such as with your network card, modem, mouse, keyboard or sound card, you should even go one step further, before calling your computer consulting experts.

Go to your Start menu. Next, shutdown your PC. Then turn the power off for a minute or so? if you’re computer didn’t power itself off on its own. Then finally power your PC back up again and see if the problem resolved itself on its own. Many times a simple reboot is all it takes.

We all know that we should back up our system as soon as possible. But if you’re like most of us, you will get to it tomorrow. The problem is that tomorrow rarely ever comes until you experience a serious computer failure and then it’s too late.

Taking the time to backup your data or entire hard drive is not as painstaking as it may seem. And the rewards of doing so will be great should your system experience a crash.

WINDOWS AND OTHER BACKUP SOFTWARE

If you have Windows XP you will need to install the new Windows backup utility from the Windows XP cdrom. Just place the WinXP cdrom in your cdrom drive and locate the line D:VALEADDMSFTNTBACKUP.

Here you see the first letter as D but if your optical drive has a different drive letter, exchange the D with your drive’s letter. To install the utility, click on the file named NTBackup.msi.

The backup utility will be installed to the system tools group. Click Start, All Programs, Accessories, System Tools, and Backup. There is a neat wizard that will walk you through the backup process.
