A Good Registry Cleaner Like Regclean For Your PC’s Health

June 30th, 2009 Anthony Jeffreys

by Michael Foreman

The high tech revolution has made computer indispensable tools for humans. We basically rely on it for everything that we do.

Students use computers. The secretary and the receptionist at the next door firm use computers. We even use computers to entertain ourselves for when we dont feel like watching the television.

Our common remedy to the situation is to go to some computer technician who charges way too much and then asks more for a hardware that has to be replaced or something like that.

We also take it upon ourselves to purchase the newest antivirus software that comes along our way.

During those circumstances when they just dont do it, you need to start thinking about your registry. But what is a registry? Your registry is the part of your computer that stores various information like the hardware connected to your computer, your system option, or your used memory.When youve been using your computer for a long time already, your registry can be corrupted and it may slow down your computer.

Your computer then needs the Reg Clean. A registry fixer program, the Reg Clean is a software that will make your registry start working perfectly again.

The Reg Clean is perfect for those who may not be computer experts because it has very simple user face. Reg Cleans ease of use is just unbelievable.

Another reason why you should get the Reg Clean is that it maintains your system even without you knowing it. You can have the Reg Clean automatically startup when you hit the power on your computer. You do not have to keep reminding yourself to scan because the Reg Clean can do it all for you.

But whats really amazing with your Reg Clean is that it creates a back up of your registry.

When you encounter serious issues, you can just open up your back up registry and you can get your system working back into normal. Its that easy.

My Thoughts On The Reg Clean Program

June 26th, 2009 Mark Lucee

by Joe Mannes

Scanning your registry for errors and ridding it of all corrupted files are tasks that you have to always do routinely to make sure that your computer performs at its optimum.

The action is very much like how an antivirus programs quarantines or deletes viruses.But Im sure you may be wondering what a registry is and why its important to make sure that its all fine.

Viruses and malwares may be things that you know perfectly but then you should also keep your registry well maintained. Keeping your registry in order is very much the same way that youd do to keep your computer free from bugs. You do this because you know that you are at risk of getting viruses from using the internet and you prevent whatever destruction a virus does by killing it before it even does harm.

Your registry is a very important part of your computer which affects your system directly because it is where essential information is stored.

These information are in the form of your system options, your attached hardware information and your used memory. You will have a perfect and error-free registry when you purchase your pc but it will start to get messed up day after day.

There are plenty of registry fixer programs out there available in the market. But for the purpose of explaining the common features of a program of that kind, well look to the Reg Clean as a model.

The very basic thing that the Reg Clean does is to scan your registry for any damaged files and then rid them out of your registry.

Its as simple as that. If you want to keep your computer free from registry errors, you can have the Reg Clean on auto start up so that it starts scanning when you turn your computer on.

But the most convenient of the Reg Clean features is how it can create a back up file of your registry so that if you have to corrupted files that are important to the proper functioning of your computer, all you need is to restore your old settings.

What to Look for in a Data Centre

June 23rd, 2009 Amy Nutt
by Amy Nutt

A data centre is a facility where computer systems and their associated components are physically housed. Data centres include a backup power supply, redundant data communications connections, environmental (climate, etc.) controls, and security devices. Any business that relies upon a computer network and web-based applications can reasonably expect to require the use of a data centre. Some companies build their own data centres on their premises. Many other companies, (especially those with complex business functions that rely heavily on technology) elect to outsource their infrastructure and web hosting to a service that includes use of the vendors data centre. The latter has several different benefits, including:

- Greater value with managed hosting options – Better use of your time and resources – Business continuity and quick responsiveness in disaster recovery situations – Bonus added-value features

Shopping for a Data Centre Once youve made the decision to outsource your managed hosting and data centre needs, you must start the grueling process of searching for a vendor. There are many different factors to consider when evaluating infrastructure-hosting vendors. Not the least of these factors is the actual data centre itself. Take the time to evaluate the data centre properly and make sure you are thorough about assessing if it will meet your organizations needs. Below are some guidelines to help get you started.

Identify Your Needs It seems logical, right? Well, you would be surprised to learn how many IT managers search for outsourced data centre space or services without really taking stock of their datas physical needs. If you are a small or large company that doesnt quite transmit much data your needs will be much different than they would be for a huge online business that sees thousands of web transactions daily. Think about what your needs are before you start meeting with vendors.

Inspect the Facility At the very least, good data centres must possess certain physical qualities and properties. When you first walk into a data centre, you may not find it to appear very interesting. Generally, you will see a large or small room (or it can be as large as an entire building) with row upon row of 19-inch rack cabinets, which contain (mostly) servers and some other communications or storage equipment. You should confirm that backup power (at least one, but more is better) in the form of uninterruptable power supplies or diesel generators are present. In order to prevent power failure to any part of the system, you should confirm that all elements of the electrical system (including backup power) are fully duplicated. The data centre should be carefully climate-controlled with air conditioning so that the temperature ranges from 20″25 C (68″75 F) and humidity ranges from 40″55%. Physical security is a crucial component in a good data centre. Make sure physical access is restricted to selected staff and select a data centre that offers video camera surveillance and permanent security guards 24 hours a day.

Dont Forget About Service Though there are many other considerations when inspecting data centre facilities, the most important ones are the redundant power supply, climate control, and security. You must consider, however, that the data centre is only part of a larger package. Dont forget to analyze all the aspects of the hosting solution you are considering. Talk to different vendors and try to get a sense of the value thats added to their overall service. If you can, try to speak with current and/or former clients of the hosting provider to ask questions about their experience with the service.

Any business that relies heavily on computer based applications can use data centers to help their business. Managed services help your business during times of crisis in disaster recovery situations.

5 Steps to Speed Up Your Computer

June 17th, 2009 Sunny Emmerwitz
by James Blaine

These days, it seems like everything runs at an extremely fast pace. Our computers can perform any task in a fraction of the time it would take humans to do it. When our PC runs slowly, it can be very frustrating to deal with. This problem is even worse if your profession requires you to be online at your computer during the day, and your work depends on a fast running machine.

The biggest issue with a slow PC is that not only can you not perform all your most important activities, but you take up time that could have been spent moving on to other important projects. Additionally, a slow computer may lead to crashes if the problem is not identified and fixed as soon as possible.

It can be hard to identify which of many issues is affecting your PC. Most likely, there are too many issues going on to know which one is causing the most problems. One thing that for sure is that your computer’s problems are results of a mix of many contributing factors.

Spyware and viruses are probably the biggest factors contributing to the problems with how your computer operates. There are others too, such as hard drive errors, not enough memory, errors in the registry, fragmentation issues, and insufficient RAM for your workload.

If you are to the point that your computer speed completely drives you crazy, you should be relieved to know that there are many different things that you can do to increase pc performance. The first and easiest way is to upgrade the components of your system. You should increase your RAM to 512 MB or more and make sure that your processor has a speed of at least 1.8GHz.

Those two things should increase speed most of the time. If the computer is still too slow, there are ways to clean it up. The cleanup process isn’t as complicated as it sounds, so here are a few ways to do it to get the PC running faster.

1. Make sure to run your anti-virus software regularly. If yours is out of date, or if you don’t have one, get new, up to date anti-virus software. There are viruses all over on the internet and there’s always a chance your computer could get infected.

2. Get a good Spyware removal program and get rid of all Spyware on a bi monthly basis.

3. Your hard drive needs to be defragmented regularly. Defragmenting is the process of collecting files from all around your computer and bunching them together to make more space available. It can take some time, but it will always make your PC faster.

4. Remove all the unnecessary programs that come pre-installed on your computer. You don’t need most of them and they just slow you down.

5. If at all possible, avoid running multiple programs simultaneously. This eats up your RAM and will always result in slower processes.

These simple steps, when done properly and regularly, can save you a lot of time and money on computer repairs. So stop your computer from acting up and running slow by making sure that you optimize your computer performance on a regular basis.

Getting the most out of your computer is a lot easier when you have a great machine. James highly recommends quality PC’s from Dell for a great mix of powerful and stylish computers.

The Basics of Wireless Network Installation

June 17th, 2009 A Nutt
by A Nutt

The appeals of Wireless network installation are numerous. The first, of course, is a limit to the number of wires running through a home or office. A wireless network also allows for a very simple installation, since your knowledge of wiring and electrical work can be minimal, but still be adequate for installing a wireless network.

Additionally, the wireless configuration allows you to have a great deal of flexibility in how you locate equipment around the home or office.

In order to set up a wireless network that is internet ready, you will need only two primary components.

The first is wireless LAN (or Local Area Network) cards. It’s important that each PC on the network have its own wireless card.

They need to be inserted into an unused PCI slot located inside of a PC. The antenna portion of the card should be at the back of the PC with the antenna extending up.

Installing the LAN card is not a complicated operation, and can be accomplished by a novice in computer installation. Simply open the computer case carefully and find the slot where the LAN card fits. There is likely only one available, but any computer that does not have a built in wireless system will have a LAN slot.

Ground yourself by touching something metal or plastic to dispel static, then screw the card into the slot with the screws provided. Make the electrical connections, replace the PC covers, then start up the computer. You’ll need to intall drivers specifically for that LAN card. Repeat for each computer that will be on the network.

The second component of a basic wireless network is the wireless router. These routers allow you to share a single internet connection between numerous computers. Depending on the router’s specifications, they can accommodate between four and sixteen computers on a single wireless router.

If you have internet from your cable provider, they may have supplied a cable modem, but those are rarely wireless. You’ll need to plug a wireless router into the modem, then route your PCs through it. If you have a DSL or ADSL connection, purchase a DSL modem.

You’ll then configure your network. Log onto your router/modem through your PC. Read the owner’s manual for the router for specific directions. You’ll want to direct it to automatically assign IP addresses to any PC attached to it. It’s recommended that you stick to basic network configurations and use the 192.168.01 as the first IP address and the 0.9 as the ending address, which gives you the potential for eight additional devices to be installed, if you like.

You want your router to be the primary gateway and also the primary DNS, so both of these boxes should be set to the router IP (182.168.0.1). Other boxes should be blank or contain default indicators.

The next step is to go to the Network Connections screen in a PC start menu, right click on wireless network and go through properties to indicate that you want the router to obtain an IP address automatically.

Are Managed Hosting And Dedicated Hosting The Same?

June 13th, 2009 A. Nutt
by A. Nutt

Both a managed hosting service and dedicated service mean running a server that is not shared with anyone else. Beyond that, the services you get will depend largely on the provider since there is no industry standards set for servers. What this means is that fully managed to one provider may mean the same as self-managed to another provider. It is the term ‘managed’ that causes the confusion.

Many things can be involved in managed hosting including – Application monitoring – System updates – Intrusion detection – Server monitoring – Backups – Database administration

These are only a few of the many items which can fall under the term of managed hosting. Because there are no industry standards, it is best to check the details before you decide on a dedicated hosting site. Managed hosting is always dedicated but dedicated hosting has different management definitions depending on the provider. Dedicated hosting can further be broken down into different types

- Basic: This is normally is chosen if low RAM, Hard Disc and Operating System on the server – High End: Usually involves Quad Core Configuration – Bandwidth Dedicated – Database Dedicated – Server Mirroring Dedicated

You will notice that ‘managed’ is not mentioned in any of the categories. Management is above and beyond what dedicated servers provide. For those still learning their way around computer terminology, it can get confusing because the words are often interchanged and terms like dedicated hosting and managed hosting are often implied to mean the same thing.

Always read the fine print when choosing a server. Terminology often is misused and you may not end up getting the services you are expecting. Until there are industry standards the confusion will continue. Simply put, dedicated hosting means that you do not have to share a server. Managed hosting means whatever the provider decides it means. Therefore, even though they are used together very often, they do not actually mean the same thing. Colocation services and dedicated services are more closely related than dedicated servers and managed servers.

In summary, there are different types of dedicated servers but they all mean not having to share a server. Managed servers can mean a variety of different services in addition to having a dedicated server. When referring to web hosting; dedicated servers are basically a rented service which includes the server, the internet connection and the software whereas managed hosting refers to the administration of the website. Managed hosting goes above and beyond what dedicated servers provide. Managed hosting is an additional service with varying degrees of options available depending on the provider. While they are often used in the same context, they mean very different things. Again, managed hosting is always on a dedicated server but a dedicated server does not necessarily mean you will get managed hosting. Different providers offer different management hosting on top of the dedicated server they provide. Managed hosting and dedicated servers do not have the same meaning.

Studio XPS 13: Well-dressed Business Laptop

June 13th, 2009 Dindo Donald
by Dindo Donald

The basic concerns of notebook makers and notebook users are on the necessary role and routine of the laptop. But with Studio XPS 13, performance is joined with a graceful look. At first look, you will notice its classy projection but theres more to it than its covering ” the nVidia Hybrid SLI graphics. Hybrid power enabled switching the graphics card to a low power consuming state and the SLI enables scaling the graphics power to the integrated NVIDIA motherboard GPU. And astonishingly, you can scarcely experience lagging using this business laptop. And it offers up to 8GB of RAM, a very good upgrade if utilized.

This notebook comes in two design options with its 13-inch screen ” the CCFL screen (compatible with 2MP camera) and the WLED screen (compatible with 1.3MP camera) which is a brighter one. Despite its differences, both has a resolution of about 1280×800, good enough to be integrated with facial recognition software which can be configured as a security feature.

You can also enjoy in the Studio XPS 13 is the backlit keyboard, hinge-lights which indicate the battery charge and computer power status, the integrated webcam, and the Vista PCRestore. The keyboard is remodelled to fit the small size and therefore some keys were moved.

Its brilliant genuine leather accents and glossy surface is indeed an attractive combination. The leather part provides the grip while the glossy element provides the elegance. But these stylish cover is negated by the aluminium hinges which looks like a misplaced plastic attachment. It certainly is a distraction.

Also, Studio XPS 13 doesnt have enough ports and connections. It only contains 2 USB ports ” one is a regular USB port while the other is an e-SATA USB port where you can also plug in a regular USB device. These two ports are found on the left side of the notebook alongside the security cable slot, VGA, Ethernet, display-port connector and an HDMI port. On the opposite side, we have the ExpressCard slot, FireWire port, DVD drive, and the power connector port. The back part has no ports and connections showing only a single vent for hot air.

Now this vent has its drawback with respect to its screen. The left side of the display will result to staining since it blocks the vent for hot air. Now, this would further effect to screen deformation, or worse, a wrecked computer screen.

Generally, this portable machine has good performance in terms of its basic functionality. But the cover function design and the connections, are a bit awkward. And with these faults, it made the Studio XPS 13 impractical with the price of $1,524.00.

Technical Specifications:
