It’s not exactly breaking news that our world is becoming increasingly wireless. Many of our daily activities that once needed a wired connection can now be done wirelessly!

The cell phone craze was probably the first revolution that seemingly happened overnight. The convenience of being constantly connected or plugged in to the your business, friends, or family was an undeniable need that was quickly met. For many people it has become a necessary in their daily lives.

Wireless computers, notebooks or laptops may just be the second wave in our struggle to becoming a totally wireless world. The ability to be constantly connected to your business and/or loved ones is revolutionizing the way we use computers and the Internet.

The ultraportable, versatile little notebook computer, will no doubt play a major leading role in our wireless struggle to be constantly connected. It’s the ‘portability’ of the notebook or laptop computer that holds the most appeal and is its major selling point. And its popularity is growing.

It is estimated that over 42 million computer notebooks will be produced this year in 2005. The market for laptop and notebook computers is growing at a rate of 20% each year according to Taiwanese notebook makers. And they should know — they make 70% of these notebooks or their components for such major players as Dell, Hewlett-Packard and Gateway.

But it’s the portability and wireless communication these devices offer that’s increasing their popularity among most users.

Just how is this wireless communication accomplished by the notebook or laptop you ask?

Wireless notebooks uses three major wireless data standards in order to transfer data. The one that is probably most common is 802.11b, also called Wi-Fi which stands for Wireless Fidelity.

Wi-Fi or 802.11b transfers data wirelessly at a maximum rate of 11Mbps for up to 150 feet. It uses the 2.4GHz radio spectrum and although it says 11Mbps, you will probably only get around 4-6Mbps in actual use. But this is enough bandwidth for high speed Internet, gaming and most file transfers.

The 802.11a is another standard that uses the 5GHz radio spectrum, so it has 8 channels available instead of only 3 that’s available with 802.11b. The ‘A’ version also permits a larger transfer, at a maximum of 54Mbps.

The other standard, 802.11g, is a hybrid of ‘A’ and ‘B’ — its also capable of 54Mbps but it uses the 2.4 GHz spectrum and is compatible with 802.11b devices. Some notebooks like the Fujitsu LifeBook N6010, have a tri-mode 802.11a/b/g wireless system that uses all three forms! The next technology in Wireless Communication is 3G EV-DO! Sounds like one of those funny robots from Starwars — but it stands for evolution-data optimized. This new technology will change how we view and use the world wide web.

Verizon Wireless 3G EV-DO began commercial operations in Oct. of 2003 and is now expanding to over 125 million US consumers by the end of 2005. With download speeds of 400 to 700 kbps and bursts up to 2 Mbps, 3G has really given us wireless Internet this time. It has or will turn the Internet into a truly wireless system that’s devoid of any cables or lines. It will be everywhere — no space within our biosphere will be without the Internet very soon.

Of course, it should be kept in mind, that any group of computers can be made wireless by using a wireless router and a wireless network adaptor for each computer. Also, many notebooks and computers come with a Bluetooth module, which allows for wireless communication between any sort of electronic devices — from cell phones to computer to stereos to headphones.

However, if you’re setting up a wireless network or if you’re using your wireless notebook or laptop at hotels and airports — security will be a concern. Anyone within distance, possessing the right equipment and a little ingenuity may get access to this wireless system. For major corporations or the lowly homeowner; safeguards need to be taken to prevent unwanted visitors from interrupting your peaceful wireless universe.

There are usually two basic methods of securing wireless networks, WEP and MAC address filtering. The MAC (Media Access Control) is the physical address or unique hardware identifier given to each device in the network. Then you manually enter a list of addresses that can use or access your wireless network.

The other filtering process is more secure, WEP or Wireless Encryption Protocol requires a shared key between the users and then using this key to encrypt and de-encrypt data that’s transmitted between your network users.

Many major hotel chains and other businesses are now offering ‘Wi-Fi’ services as an added convenience to their patrons. These ‘hot spots’ are popping up everywhere, even at some gas stations. You may need to sign in or get a password or key to access these services.

But like your cell phone conversations, any radio transfer or transmission will not be as secure as a wired connection. Keep this in mind if privacy is a major concern for you. But don’t let it stop you from enjoying the convenience, portability and practicality of your wireless notebook or laptop.

It’s a wireless world after all.

Science-Fiction meets reality with this new video display technology.

The Heliodisplay includes patented and patent pending technology to transform normal ambient air and display video images into free-space. Some Heliodisplay models are interactive allowing a finger or hand to move images around in the air as if one were grabbing a tangible object.

The Heliodisplay requires a power outlet, and a computer, TV, DVD or alternate video source. The current version of the Heliodisplay projects a 22′ to 42′ (depending on model) diagonal image that floats above the device.

The Heliodisplay system is backward compatible and accepts most 2D video sources (PC,TV, DVD, HDTV, Video game consoles). For connection to a computer, the Heliodisplay uses a standard monitor VGA connection; for TV or DVD viewing, it connects using a standard RGB video cable.

Interest in this new technology has been so strong, that curious visitors have crashed IO2Technology’s website.

Obvious Applications :

Less Obvious Examples:

While the new video capability will doubtless usher in a new era in computing and home entertainment, I wouldn’t rush out and buy one just yet. That is, unless of course you have a burning desire to part with some extra cash in hurry.

I haven’t seen the system in person, so I can’t say for sure, but the old computer axiom of “Never buy version 1.0 of anything.” probably applies here.

Odds are that the price is out of line for most people. Also, all the kinks in the system are most likely not perfected yet.

I get this impression because IO2Technology is taking only limited numbers of orders right now. This tells me that the company has limited production capacity and is not fully prepared for demand. They probably haven’t sold enough units yet, to account for all possible system configurations and usage scenarios. So for now, I’d steer clear of buying one for home or small business.

Still, the announcement is impressive because it is bound to create another era of “Star Trek” type innovations and change some of the ways that we react with our computers and televisions.

If your computer crashes unexpectedly, everything comes to a halt. Prior to crashing your computer will likely start freezing up. This is an indication that your computer has to be fixed before it gives up completely. Fixing the computer does not need to involve replacement of the computer with a new one. Your current computer likely just needs a little attention.

Identifying the reason for crashing is essential prior to fixing the computer. The initial step is to reboot your computer. If the rebooting goes smoothly, it is apparent that you are facing a problem with your registry. If you cannot reboot instantly, then rebooting your computer in safe mode and locating a registry cleaner to fix your problem is essential.

Every file present in your registry contains a command or direction for every program and application on your computer. Registry files are the files that give your computer the instructions for what to do next. If these registry files get corrupt or misplaced, your computer fails to understand what to do. In these instances, your computer loses control, eventually leading to a crash.

At this stage the priority is to fix these registry files. In such situations it is suggested that you do not try to fix the registry yourself. Immediately find registry cleaner software and scan your computer to locate any errors. This software will identify all the missing entries or errors, restoring them right away. In many cases, your computer will be back to normal. It is recommended that you run this software once a month for best results.

Another cause of crashes is when new software is installed. If you have recently installed a new program or file, this could also be the source of the problem. You should locate the program and uninstall it. In case you are incapable of booting up your computer in normal mode, you are advised to try booting in safe mode first. If the new program is at fault, removing it should solve the problem. Obviously you would not re-install that program later on.

Most computer crashes occur due to a problem with the computer’s registry files. This is the core reason for any crash. So, running registry cleaning software and eliminating all errors is essential to avoid computer crashes in the future. Subsequently, fixing the registry files will keep you from having to ask the question ‘how do I fix a computer crash’ again.

I’m sure most pc users have probably asked themselves the question ” Why is my computer running so slow? ” several times and have struggled to come up with any logical reasons. There really are many reasons why a computer can suffer from speed degradation and less overall functionality but most of the time you will find that it is in fact the windows registry that lies at the core of these problems. Now most of us are aware that there are many free registry cleaner tools available on the internet which can fix these problems but how many of us know what the registry is?

The registry is a very important component of your operating system in that it acts as a central database which stores all of your operating systems hardware and software related configurations. What people don’t realise is that the information in this database is constantly changing due to the fact that most pc users frequently add or remove hardware and software components from their pc’s. Over a period of time this will end up having a negative effect on the registry as it will build up a large amount of redundant and obsolete entries which will consequently affect Windows’ ability to process information from it ultimately resulting in poor program and task functionality.

When this happens you will start to suffer from symptoms like speed degradation, corrupted DLL files, missing application files, unused start menu items, deleted desktop shortcuts and the inability to execute programs and tasks.When this happens you will know that its time for a scan with a free registry cleaner tool. So the next time you ask yourself the question ” Why is my computer running so slow? ” you will at least have a bit more understanding as to why this is.

Reg Cure is my recommendation as the best free registry cleaner tool available today and has continued to gain much popularity because of its solid scanning and repair abilities. If you would like to download the latest free version and scan your pc now please visit the website below.

Changing the ergonomics for computer workstations was certainly a positive step in helping people avoid the repetitive stress injuries so commonplace at one time.

Carpal tunnel syndrome seemed to affect almost everyone before positive steps were taken to identify the culprit in this new epidemic. Many of my patients that work at computer workstations even have the “proper ergonomic workstation design” picture displayed prominently on the back side of their i.d. badges.

Yet these people are patients in my office for conditions and back problems that aren’t being helped by ergonomics for computer workstations. It’s still possible to slouch and slump in your workstation.

Just being seated for long periods of time creates shortened hamstrings and hip flexors. Slouching and slumping will continue to put stress and strain on your upper back and neck.

The one thing I’ve seen repeatedly that even the best ergonomics can’t seem to help is bad posture. I keep seeing new and improved reminder systems that will help you remember to sit up straight, but less emphasis on really making a lasting change.

Alarms can be shut off or ignored. You can only get reminded or scolded so many times about your posture before you start to tune it out. If you engage in preventative things like stretching and strengthening activities to improve your posture, no one will need to remind you to sit up straight and your workstation ergonomics will be less of a factor in keeping your injury-free and out of pain.

Dr. Natalie Cordova, a chiropractor and posture expert, wants to help you change your posture for good. Learn to improve posture at http://www.ImproveMyPosture.com

Are you frequently asking the question “Why does my computer run so slow”? This was also a question I kept asking myself when my computer was running horribly slow in the past. In fact, anyone who has used their computers for a long time will probably ask the same question at some point.

A slow computer can be a result of various issues. This article will cover the most common causes of a computer slowing down, and how to finally get your computer to run fast again.

Corrupted Registry

90% of the time, a computer will slow down as a result of errors in the computer registry. It is very easy for us to neglect our computer registry, and over time, the registry entries in the registry will get horribly messy. To fix your registry properly, you will need to download a registry cleaner. This program will easily identify all the bad registry entries in your system for you with a scan, and then fix them after you have approved the software to do so.

Running Too Many Programs

You may have installed software that are running in your startup section which you may be unaware of. As more and more programs get installed, your system starts to slow down as it uses up more resources just to keep these programs running in the background. These programs should be turned off or your computer will crash often.

If you are looking to fix your computer, these are the 2 areas that I would look at. I personally managed to get my slow computer running a lot faster after using registry cleaner to fix it. Get your computer back to its original working condition again!

Is your computer constantly slow or crashing? Read the author’s review of the Best Registry Cleaners on the market now at http://www.review-best.com/registry-cleaner.htm and completely clean up your computer registry in 2 minutes!

Overclocking gives your computer an added edge. By overclocking, you push your hardware to be at its ultimate performance. CPUs can often perform more than their official specifications. A 3 ghz can actually run at a peak of 3.3 gigahertz performace. One can safely and successfully push their hardware performance to its fullest. That’s where overclocking comes in.It speeds up your system and provides strong signals.

Although not an absolute, the general rule is, the higher the model, the greater chances of a successful and problem free overclocking. Newer models have more developed parts that are able to run higher than rated speeds and can adjust well to overclocking. A better way to determine if your pc is capable of being overclocked is to find, dowload (for trial and subsequent purchase, but some may be free), and use a software that works at identifying your computer processor.

Getting full specs or information on your hardware can give you clues as to how able your computer peripherals are in adjusting to speed modification and if they are able to endure standing heat. By knowing your pc’s limit you may be able to determine how far you can overclock your computer.

Besides software downloads, much information can be gotten thru internet research. There are numerous overclocking databases online. Most PC websites tackle issues on overclocking. You may also join forums specifically tackling overclocking issues.Most forums nowadays are free for joining. There you are able to glean wisdom from computer enthusiasts who have expert knowledge on overclocking.

Not all hardware can be successfully overclocked. This is most especially true with older computers as their hardware peripherals are not as fully developed and flexible as that of more recent models. Proceed to overclock with great care. Check your computer specs well before overclocking it. Older computers are less able to adjust to speed modification and may experience great problems after being overclocked. When you overclock an unable pc, chances are, you will experiece system data loss, frequent booting problems, frequent system shut downs, frying, crashing, and complete system breakdown. So, know full your computer make up before attempting to overclock it.

Every CPU has a set internal number, it’s called a clock multiplier. Multiply that number with that of the ‘front- side bus’ (the reference clock) and you get the processor’s clock speed. By increasing multiplier settings or only the ‘front-side bus’ or by doing both, one can overclock the CPU. However, CPU manufacturer products often have multiplier locking. This is a measure they take to ensure that the intended speed is run by the processer. When the multiplier is locked, it can’t be changed or modified in the BIOS. They do this foremost to prevent CPU ‘re-markers’ from peddling inferior products expensively. Consequently, overclocking is prevented.

The good news is, not all of them are locked. Manufacturers are now offering product lines which do not have the multiplier locking feature. With these new product series, one only needs to adjust the multiplier from ten to eleven without needing to overclock via front-side bus.

Overclock your computer slowly, a level at a time. Abrupt speed setting changes may cause instant system instability or breakdown. Slow overclocks allow you to have a thorough observation on how your computer is reacting to the modification. Work on each level for a long time to see possible system problems before moving on to the next level. Overclock only when hopes are high for your hardware. If not, just budget for a new one. Else, you may find yourself spending much on repairs.

Generally made of carbon frames and glass screens, computer monitors can display color, monochrome and grayscale graphics. There are different kinds of computer monitors depending on their resolution range or display device — and they affect your eyes in different ways.

Kinds of computer monitor

CRT or Cathode Ray Tube computer monitors are the most common. They are compatible with Macintosh and PC systems. Although bigger than other monitor types available, CRT monitors are still ideal for home and office use. They are also cheaper.

More expensive flat screen monitors have higher resolution, while LCD computer monitors have wider color ranges and high-contrast displays. For generating faster pixels, TFT computer monitors are available. Most of these computer monitors have built in speakers, mobile bases and security locks.

Your eyes and your monitor

Are you suffering from eyestrain from working long hours in front of a computer? Do not worry. This condition can easily be averted by adjusting your monitor as well as your usual work methods.

You can reduce eyestrain simply by adjusting the font quality and refresh rate of your computer. Make sure that your computer screen is slightly below your eyelevel and at least 20-26 inches from your eyes. Monitors are equipped with lighting systems which you can adjust to reduce glare or any reflections.

Proper cleaning is also important. Monitors that are clean and dust free are less likely to cause eye irritation.

Also take time to rest your eyes even for short periods. Walk away from your computer and look out the window. This can contribute a great deal in reducing computer strain.

BUYING TIPS AND SAFETY INFORMATION

Environmental changes mean that the way we use water is fast changing. Even in Western Europe and other places where rainfall is common, users were allowed unlimited access. Since water needs energy to produce it (to filter, pump and control it), many countries are gradually installing meters to control and reduce consumption. If you are a small household, you can actually save a large percentage off your present water charge with this series of tips.

Top tip no. 1: When you use your hot tap, always fill a container until the water gets warm

You will be amazed at how much water needs to pass until it gets warm. Even with a modern combi-gas boiler, it still takes about a *bucket* load before the water gets warm. Assuming you have easy access to your toilet’s water cistern (the storage for your w.c’s water), tip it in there. Another option is to use it for washing, where it might get boiled anyway. A further option is to use it for your garden plants. You can even drink it, providing it has originated from your rising main (the direct pipe from your utility company), rather than being stored in a water tank somewhere in the house.

Top tip no. 2: Monitor your water usage

This is especially true when you have a new meter, new house or buy a second-hand house. I speak from experience - it was three months before I discovered our meter was leaking. Monitor the water usage from the outset by checking your meter’s reading - your water company might tell you what you expect to use depending on the number of people in your home. This is particularly important if the meter is outside the walls of your home (you should see leakage inside your home). If in doubt, the easiest way to check is to turn off all internal stopcocks (the taps controlling the water pipe(s) inside your home, thus allowing water to pass from your meter to the start of your pipes. If the meter dial is still turning, it suggests (a) a break in your supply pipe or (b) a fault at the meter. Get the water company out to investigate.

Top tip no. 3: Don’t run the cold tap for any length of time in the belief that the following water is fresher

This is waste - buy a kitchen water filter instead and fill that from the outset. If you’re in a hot country, you can leave your filter in the fridge already cooled.

In the next article, I will look at further cost and environmental savings.
