While most parents are aware of the potential dangers of allowing children to use chat rooms and social networking sites without supervision, many may be unaware of the danger posed by games consoles that connect to the web.

At present, the most popular web-enabled home game consoles on the market are the Nintendo Wii, the Microsoft Xbox 360 and the Sony PlayStation 3. These consoles all offer the ability to send files such as photographs to other users via email.

In addition, there are a range of games available for each console that allow users to interact with other gamers over the internet, allowing users to converse in written text, audio and even video. All this functionality, while very popular among young people, also makes games consoles a potential means to offend for internet predators.

Online child grooming is the practice of meeting and befriending a child online with a view to winning their trust in preparation for attempting to engage them in sexual activity. In 2003, for example, prosecutors in Houston, Texas tracked down and arrested a 24 year old man who had made contact with a 13 year old girl via her Sony PlayStation 3 and persuaded her to send him naked pictures of herself using the console.

Since internet usage exploded in the mid-nineties, laws have developed to criminalise online child grooming. The Sexual Offences Act 2003 made it an offence to arrange a meeting with a person under the age of 16 with the intent of committing a sexual act, so the meeting does not have to have taken place for the perpetrator to be prosecuted, as long as evidence can be presented to prove that the grooming took place.

In most cases, computer forensics experts are engaged by police forces and prosecutors to help identify perpetrators and analyse the consoles for evidence. At the time of writing, it is possible for a computer forensics analyst to trace a perpetrator to a physical location via their registered profile or IP (internet address) and to extract evidence of criminal activity from a console, even after a suspect believes it has been wiped of data.

Parents can take an active role in protecting their children by utilising the parental control options present on all of the above consoles. These allow parents to block particular websites or functions, or indeed prevent web access altogether. However, a March 2009 report from computer security firm Symantec suggests that many parents are not taking adequate action to protect their children online.

The report revealed that UK children spend an average of 43.5 hours online per month, but 46% of parents stated that they had not set parental controls, 25% stated that they had not spoken with their children about practicing safe habits online and 28% said they did not supervise their child’s internet usage.

With a recent report suggesting that as many as two thirds of UK children own a games console, it seems that millions of young people could be vulnerable to online abuse. As a concerted and coordinated effort by console manufacturers, parents, police and prosecutors seems the most effective way to ensure that the activities of internet predators are monitored so that abuse can be prevented and perpetrators can be successfully prosecuted.

Every generation of Microsoft operations systems increases the demands on your computer’s hardware. A computer than can run Windows XP just fine may struggle under Vista. It is almost certain you’ll need to add Compaq RAM memory before upgrading your operating system.

Vista’s Memory Requirements

If you want to install Vista on your Compaq, Microsoft recommends at least 512 MB of Compaq RAM memory to run Vista Home Basic and 1 GB for Home Premium, Business or Ultimate. However anyone who knows much about PCs knows that suggested requirements are fairly laughable. Yes you could get Vista running on this amount of memory and it will work fine, as long as you don’t run any other software. Fire up your word processor or your checkbook program and suddenly the system slows to a crawl. If you enjoy games, good luck trying to get a computer game to run with that amount of memory!

A general rule of thumb is to at least double the memory required and that means a Compaq memory upgrade of 1 GB for Basic and 2 GB for the other versions. More is better, so don’t be afraid to max out your computer’s memory capacity. You will be surprised how much faster things run when you do.

The Limits of 32-bit Vista

Your Compaq RAM memory is broken out into many, many tiny pieces of information. If you have 1 GB of memory, you have just over one billion compartments that the computer can fill with data. However, to find that information the computer needs the address of the right compartment. Without getting into the tedious subject of binary math, a 32-bit operating system like XP can address up to 4 GB of memory. More than that and the operating can’t use it because it can’t create a number big enough to read or write data there.

However a 32-bit operating system addresses 4 GB of memory only theoretically. Many addresses are reserved by the computer hardware so can’t be used by Windows or by other software you run. That means that realistically a 32-bit operating system can access only about 3.5 GB of memory. While that’s adequate for now, will it be adequate in the future?

64-bit Vista Breaks the Barrier

Users who want to install truly huge amounts of Compaq RAM memory can choose a 64-bit version of Vista instead of a 32-bit version. These have much higher memory limits. 64-bit Vista Home can fully support up to 8 GB of memory, Home Premium 16 GB and other versions 128 GB or more!

Most versions of Vista, particularly the ones pre-installed on off the shelf computers such as Compaq, are 32-bit. Buyers must explicitly ask for the 64-bit version. When you do so, the sky’s the limit on your Compaq memory upgrades. Lots of memory translates to terrific performance, so don’t let your system be handicapped by 32-bit Vista.

C OKelly is an author for House of Memory, offers more than 10,000 types of memory for computer models of all types including Kingston memory , Compaq RAM memory, and other affordable ways to complete your Compaq memory upgrade.

Registry errors are the difference between a fast, fully-functional brand new computer and an old slow computer filled with error messages. Registry errors can cause programs to crash, your entire computer to freeze up, the dreaded Blue Screen of Death, and even your computer to shut down unexpectedly.

Simply cleaning the registry, however, will speed up and fix your computer dramatically. This article will give you three ways to do that.

HOW CAN I FIX REGISTRY ERRORS?

Fix the registry your self

Fixing registry errors yourself is possible, but it is difficult, time consuming, and dangerous. Because tinkering with the registry can easily screw up your computer for good, it is not easy to access, diagnose, or repair. The registry key information is highly technical, and requires a lot of computer knowledge to decipher and understand. If you have a PHD in computer science and several weeks of free time available, you could theoretically analyze and clean your registry yourself.

Although generally inefficient and risky, this approach does have has its uses. If you have the technical knowledge, you may be able to successfully isolate and repair one specific problem that’s really annoying you. Repairing one problem would also be much faster than trying to clean and fix the entire registry, taking only hours instead of weeks.

Have a professional fix your registry

If you lack the technical expertise to clean the registry yourself, you could always have a professional at a computer repair shop do it. This will at least prevent the computer from getting worse by accidentally changing or deleting the wrong registry key. You can be fairly confident your computer will run faster and smoother once you get it back.

On the other hand, a professional repair is expensive and time-consuming. It will take a least a day, possibly more. You’ll most likely be charged an hourly rate by the computer repair technician, which can quickly add up. Finally, there is always the possibility of the repairman snooping through your confidential information.

Use a registry cleaner program

Of all three solutions, this is the easiest, quickest, and cheapest. Besides, if you take your computer to a repair shop to clean the registry, they will mostly likely use a registry cleaning program themselves to do it-only you’ll have to pay quite a bit more than it would cost you to simply buy the registry cleaning program yourself.

Registry cleaning programs are simple and easy to use. At the touch of a button, the program will scan your computer’s registry for error (which may take several minutes), then display a list of the errors it found. At the touch of a second button, it will fix the errors it found.

There are tons of registry cleaning programs available, ranging in price from free to expensive. Free registry cleaners are cheap, but usually not as efficient as the paid ones. They may only look for certain types of registry errors and ignore others. Even in the categories they’re looking for; they may not find as many errors as they could.

Paid registry cleaners range in price from $20 to over $100, but most are under $50. These usually search for more types of errors, and find more in each category. The program can be regularly updated. Finally, if fixing something in the registry backfires and causes another error, most paid registry cleaners have the option to restore the registry to the way it was before the new error occurred.

Finally, when you buy a registry cleaning program, rather than paying a repairman to run the program for you, not only do you pay less, but you can run it as often as you want. Buying a good, reliable registry cleaner is definitely the cost-effective and efficient way to go.

Making sure your scanner is in tip top condition is the key to the life of your equipment and good quality image scans. Experts recommend that a scanner flat bed be cleaned about every 100 scans and that the rollers inside be cleaned every 3,000 to 5,000 documents. Usually the glass flat bed of a scanner can be cleaned with glass cleaner, but the interior is trickier, many times requiring the help of a professional or the use of a scanner roller kit.

To perform a maintenance cleaning at home, you will need:

1. Non-streak glass cleaner
2. Soft, lint-free cloth
3. Can of compressed air
4. Mild soap/detergent
5. Scanner roller kit (optional)

To Clean the Scanner Bed:

A good scanner bed is made out of glass, and as we all know, glass can get dirty and dusty at the drop of a hat. And a scanner that is not crystal clear makes for an image that can be distorted or look soiled. To begin, spray the glass cleaner on your non-abrasive cloth. Wipe glass bed until you have gotten rid of all fingerprints and debris. Then, wipe the bed again with the dry end of the cloth to get streak-free results. Be sure to never spray the scanner bed surface directly with the cleaner.

To Clean the Chassis (Scanner Exterior):

First, remove all dust and dirt by spraying the chassis with a can of compressed air. Second, work on any grease marks found on the chassis with warm soapy water that contains a mild detergent safe for cleaning plastic. Your ordinary liquid dish soap is appropriate for this type of surface. For stubborn grease spots, you can also use a solvent.

To Clean the Scanner Interior:

Most scanner manufacturers do not recommend any interior cleaning be performed except by a professional service. Some manufacturers, however, suggest using a specific cleaning device called a scanner roller kit you can purchase at stores that sell computer supplies. But, if you don’t want to front the cost of either of these options, some manufacturers recommend cleaning the bed with either a soft camel hair brush or a can of compressed air.

Preventing Dirt and Debris from Coming Back:

To make cleaning easier each time, follow these simple rules:

1. Do not scan documents that have white corrective liquid on them. With the heat the scanner produces, the liquid can become soft and stick to the scanner bed.
2. Always keep an eye out for dirt and debris that can fall onto your scanner flat bed. Make sure you do not have food around your scanner as this is one of the biggest culprits.
3. Be aware of larger items such as staples or rubber bands that can fall into the crevices of your scanner.

If you work on a computer network at your job, you will have some idea of what computer security is. Computer network security systems provide the computer security that spans a network of connected computers and is a process of prevention and detection of unauthorized use. Through use of preventive measures the computer network security system will not allow any unauthorized user, sometimes called an intruder, from gaining access to any part of the computer network.

On the other hand, the detection system within a computer network security system will help find out if somebody has tried to make unauthorized entry into the network and in case they succeeded, what were the consequences and what actions did they perform.

Since computer networks are used for many activities that range from banking to investing to shopping as well as communicating among groups and individuals there arises a need to keep the computer network free of attack such as sending forged emails as well as examining personal information and a whole lot of other malicious and unwarranted activities.

Hackers, attackers, crackers or intruders as they are called, are people who do not care about niceties of the law and are constantly devising ways and means to hack into computer networks to gain control of computers to launch attacks on the entire network. Gaining control of a computer on the network allows them to launch attacks, while at the same time concealing their true location. The intruder is constantly discovering holes to exploit computer software and so a computer network security system is essentially needed to not only ward off attacks, but also to pre-empt them.

Firewalls are extensively used in computer network security systems as preventive measures that are designed to enforce an access control policy between computers on a network. The network firewall is a dedicated device that can protect one or more computers. In addition, the computer network security system should have proper and updated anti-virus software installed on the computers across the network.

To Prevent Attacks, Disconnect the Computer When Not in Use

Once the computer is not being used it should be switched off or its Ethernet interface should be disconnected because then the intruder cannot attack the computer. One may also take the precautionary step of disabling Java, JavaScript and ActiveX, if possible. All important data should be regularly backed up on auxiliary storage devices so that there is no permanent loss of important and vital information were the network to be attacked.

Eddie Lamb publishes an abundance of information on a range of topical subjects. This article A Computer Network Security System Should Prevent and Detect Intruders, is just one of a host of useful articles about Security Systems listed on our site map at Security System Guard.

A charting software for traders must tick several boxes. Your choice for charting software is vital to the success of your trading system. A well-designed trading system is useless without the right charting software tools to implement it. However, choosing a charting package, or deciding whether to use one at all, can be very confusing for a newbie trader. This is especially true when you consider that there are literally hundreds of software packages available to assist traders.

You don’t need to spend thousands of dollars paying for good, reliable charting software. Often the price is inflated to capitalise on the belief that the more expensive the software, the better. In truth, most charting packages perform very similar functions and a charting package under $1000 will perform just about all of the tasks required by even the most advanced traders.

When choosing your charting software, here are six things you really need to look for:

1. Longevity. Look for a package that’s stood the test of time. There are plenty of packages on the market, but some of them are here today, gone tomorrow. There’s nothing worse than taking the time to learn a new piece of software only to find it’s no longer supported, since the company that developed it has gone down the corporate drain.

2. Large user base. Choosing a package that has a large, established user base and is supported by well-attended forums will mean that if and when you need help, there will be plenty of support channels available to you (outside the developers themselves). What’s more, there are great new discoveries made by the community that the developers may have never even thought of.

3. Flexibility. Your package should have plenty of flexibility for coding so you can easily define your entry and exit criteria. Avoid packages that are so pre-programmed that you really don’t have any control over what they do.

4. Market scanning ability. A good charting software package will have the ability to quickly and accurately scan the market for securities exhibiting criteria you define.

5. Back testing facility. Choose a package that has a back testing facility within the charting package itself, or one that is at least compatible with a well-established back testing package.

6. Independent data plans. Beware of software packages that force you to use their data. They may be offering you the software cheaply - or even free - but then they tie you into their (often expensive) data plans. It’s best to find a charting package that has third party independent data plans.

And finally, if you’re still having trouble selecting between a few different packages be sure to ask about trial versions. It’s a great way to see if the package is right for you.

Correctly diagnosing PC problems can be difficult and time consuming. It makes it easier when you have a guide to look at for some of the most common problems:

Sound issues: No sound coming from speakers. The first thing to do, would be to make sure that the speakers are plugged in to the computer. If they are, check the speakers to see if they have a switch on the side indicating on or off. Many speakers also have a volume control right on the side. If this is not the problem, go to the next step.

In a shell, type in a play 1, if it works the system will tell you all of the different sound cards installed, and it is probably just the volume being muted. Go to sound mixer and adjust volume control.

If it does not work, then type in lscpi v if it is successful, the sound card will be displayed. Leave the shell going, and search for the chipset maker of your sound card. This is the thing that makes the sound card work. It is called the driver. Now, go back to the running shell, and type in sudo modprobe snd. Be sure to press Tab before Enter so that you can see the module list. Hopefully, you will find one to match the driver you already found. If your driver is vr244, then you put in sudo modprobe snd vr244. Viola! With any luck , your driver will be installed.

Another common PC problem is issues with your graphic cards. Many times, people report problems with graphics cards when they are playing games on their PC. One of the most common causes of this is too much heat. If you hear a crackling sound, then try putting a fan close enough to blow into the computer to cool it off. Cleaning the heat sink of any dust helps also. Since clean equals cool.

Computer running slow is a real problem today. There are many potential causes for this. The first cause to check for is spy ware or ad ware running in the background of your computer. This can really slow a computer down. A good spy ware program will find and get rid off all those little potentially dangerous spy bots that are lurking in your computer. You should also have a good antivirus program installed at all times. A computer can become infected in seconds. This is another candidate for causing slow computers. Fragmentation of the hard drive occurs when files are moved, changed or deleted. The files then spread out, causing slower computer response. Your computer should have a defrag program to fix this problem. It will allow you to check the volume first, and then defragment if needed.

When too many programs are running at startup, this can contribute to a sluggish computer. There are programs designed to stop unnecessary programs from running when Windows starts. The disk cleanup utility in Windows is a program that you should run regularly. It will compress old files, empty the recycle bin, and delete other unnecessary files.

Most of the time when you hear noise coming from a hard drive, it is a bad sign. More than likely, the hard drive is close to failure. You should run a hard disk diagnostic software program, and then back up important data and be prepared to buy and install, or have installed, a new hard drive. Please note that some sounds are normal in a hard drive. If you hear a grinding, loud clicking, or squealing sound, it is probably the hard drive on the brink of failure. Take recommended steps to save precious data.

With the advancement of technology, come also advances in problems associated with them. Although diagnosing PC issues can be time consuming and nerve wracking at times, with some patience and know how, most PC problems can be overcome.

Frustrated by Windows that do not load quickly? Are you forced to stare at blank azure blue screens that welcome you to windows but do not show you the files on your desktop quickly or give you access to the documents that you need urgently? De-fragmenting the hard disk, removing temporary files, running virus scans, removing unwanted software and doing everything you can think of does not seem to help? You problem could be your Windows registry. What you need is a registry cleaner!

Will reformatting the PC not help? Sure it will, but consider–the amount of time and labor you will have to put in to rebuild your user interface! The innumerable applications that is part of your work routine will have to be reinstalled, configured and set up again so that you can settle down to do the job. All this for nothing! All you perhaps need to do is clean up the registry with a registry cleaner. This should not take you more than a few minutes to half an hour!

Registry cleaners check application paths, uninstall info files, help files, all file extensions, fonts, shared DLLs, folders, start up programs and all files and folder that could be the cause of your PC’s slow response and your consequent misery.

The registry is a kind of register for all the software you load into the system. When you install or uninstall a software application, files and folders in the registry are checked, updated or deleted. Sometimes, the deletion is complete and sometimes partial. Over the years deleted applications leave their stamp on the registry. Undeleted registry entries of applications you have uninstalled and no longer use build up in volume. When Windows loads, it checks the registry for all the applications that need to be loaded into the user interface. It looks at each entry and picks up the relevant information and discards the irrelevant. The process takes longer and longer as “historical remnants” are examined and discarded meticulously. You are forced to stare at the welcome screen with a sense of frustration and chagrin.

So what are your options? You could do a manual clean of the registry. That could be dangerous unless you know for sure, what you are doing. You could end up deleting one of the entries that fire up your most frequently used application and leave you ruing the day you opened up the registry for a manual clean. Alternately you could use a registry cleaner that will quickly and accurately identify all those registry entries that are no longer in use and remove them for you.

If your budget is limited, you could try one of the free registry cleaners to clean out your redundant registry entries. If your budget is unlimited (lucky you!), you could buy yourself a registry cleaner that has a lot of advanced features.

Registry cleaners can do an automatic scan or a custom scan. Automatic registry cleaner scans help the novice fire up the registry cleaner and relax while it does its job efficiently and effectively. They can even set up the registry cleaner to fire up on its own at predefined time frequencies and perform the operation in the background while they continue with their work. Custom scans are for the geeks who know exactly what they want to achieve and have the ability to configure the scan to their needs.

So, if you are indeed cursing the slowness of the windows loading process, get yourself a registry cleaner and banish the problem forever!
