With more and more people buying cell phones, it becomes more significant to know how to use your cell phone without looking obnoxious. Cell phones play an important role in our lives, but cell phone rage, like road rage, air rage and general rage is rising. Here are some tips for cell phone etiquette.

Out with a group of friend(s) and your cell phone rings? Excuse yourself from the group and take the call elsewhere. Taking the call elsewhere will not disrupt the flow of conversation within the group.

With a friend and the cell phone rings? Keep the call short and sweet. Otherwise, it gives the appearance that the friend you are with is less important that the caller.

Out on a date? The point of the date is to be able to spend time to get to know the other person. I would suggest that you disregard such calls. The romance is lost by the sound of the ringtones of your cell phone. Your date will appreciate your undivided attention.

It’s a good idea to put your cell phone on vibrate when in restaurants, theaters, churches, weddings and funerals. When I’m out in a restaurant, I feel like asking for the non cell phone ringing section. Like many others, it is not often do I get to spend a quiet evening away from the children, work or other distractions. An evening going out to dinner with my husband is supposed to be relaxing, and we do not enjoy being distracted overhearing how wonderful your life has become since you started using Viagra.

I was in a movie theater once and someone’s cell phone rang and the individual took the call. Someone else in the theater did not react well to the intrusive call and started shouting at the cell phone user. The cell phone user ignored the cell phone raged individual and the focus of the movie was lost and everyone’s attention was on these two people. While nothing came of the incident, a relaxing evening out with my husband was lost. I felt like asking for our money back. The next time we will.

There is no question that cell phones are an important part of our lives. Use cell phones with good manners. Everyone will appreciate it.

P.S. – As for ringtones… Not all people will appreciate listening to the latest pop tune or classical music each and every time your cell phone rings. May I suggest using the vibrate feature instead of your ringtones in a public place.

Data loss is an expensive reality. It’s a hard fact that it happens more often then users like to admit. A recent study by the accounting firm McGladrey and Pullen estimates that one out of every 500 data centers will experience a severe computer disaster this year. As a result, almost half of those companies will go out of business. At the very least, a data loss disaster can mean lost income and missed business opportunities.


The other side of data loss is the psychological and emotional turmoil it can cause to IT managers and business owners. Despair, panic, and the knowledge that the whole organization might be at risk are involved. In a sense, that’s only fair, since human error is one of the two largest contributing factors in data loss. Together with mechanical failure, it accounts for almost 75 per cent of all incidents. (Software corruption, computer viruses and physical disasters such as fire and water damage make up the rest.)


Disk drives today are typically reliable. Human beings, it turns out, are not. A Strategic Research Corp. study done in 2000 found that approximately 15 per cent of all unplanned downtime occurred due to human error. A significant proportion of that happened because users failed to implement adequate backup procedures, either having trouble with their backups, or having no backup at all.


How does it happen that skilled, high-level users put their systems – and their businesses – at such risk?


In many cases, the problem starts long before the precipitating system error is made, that is, when users place their faith in out-of-box solutions that may not, in fact, fit their organization’s needs. Instead of assessing their business and technology requirements, then going to an appropriate engineered solution, even experienced IT professionals at large corporations will often simply buy what they’re sold. In this case, faith in technology can be an vice instead of a virtue.


But human intervention itself can sometimes be the straw that breaks the technology’s back. When the office of a Venezuelan civil engineering firm was devastated by floods, its owners sent 17 soaked, mud-coated disks from three RAID arrays to us in plastic bags. A tough enough salvage job was made even more complex by the fact that someone had frozen the drives before shipping them. As the disks thawed, yet more damage was done. (After eight weeks of painstaking directory-by-directory recovery, all the data from the remaining fifteen disks was retrieved.)


Sometimes, the underlying cause of a data loss event is simply shoddy housekeeping. The more arduous the required backup routine, the less likely it will be done on a regular basis. A state ambulance monitoring system suffered a serious disk failure, only to discover that its automated backup hadn’t run for fourteen months. A tape had jammed in the drive, but no-one had noticed.


When disaster strikes, the normal human reaction is panic. Because the loss of data signifies critical consequences, even the most competent IT staff can jump to conclusions, and take inappropriate action. A blank screen at a critical time can lead to a series of naive decisions, each one compounding the preceding error. Wrong buttons get pushed, and the disaster only gets worse. Sometimes the pressure to correct the system failure speedily can result in an attempt to reconfigure an entire RAID array. IT specialists are typically not equipped to deal with crisis modes or data recovery techniques. Just as a good physician is trained to prolong life, the skilled IT specialist is trained to keep the system running. When a patient dies, the physician turns to others, such as nurses or counselors to manage the situation. When significant data loss occurs, the IT specialist turns to the data recovery professional.


Data recovery specialists are innovative problem solvers. Often, the application of basic common sense, when no-one else is in any condition to apply it, is the beginning of the journey towards data recovery. The data recovery specialist draws on a wealth of experience, married to a “never say die” attitude, and a comprehensive tool kit of problem-solving procedures. Successful recovery outcomes hinge on a combination of innovative logistics, applied problem-solving, and “technology triage,” the process of stabilizing an affected system quickly, analyzing and treating its wounds, and preparing it for surgery. The triage process sets priorities, such as targeting which files are needed first or which are absolutely vital to the functioning of the business, and establishes whether files might be recovered in less structured formats (such as text-only), which may be desirable when time is crucial.


The art and science of professional data recovery can spell the difference between a business’ success or its failure. Before that level of intervention is required, though, users can take steps to ensure that the probability of a data loss disaster is minimized.


Basic to any business technology plan is a regular fire-drill procedure. Back-up routines may be in place, staff may assigned to specific roles, hardware and software may be configured – but, if the user isn’t completely sure that everything works the way it should, a data loss event is inevitable. Having adequate, tested, and current backups in place is critical. A hardware breakdown should not be compounded by human error – if the malfunctioning drive is critical, the task of dealing with it should go to a data recovery professional.


Just as data loss disasters are rooted in a combination of mechanical failure and human error, so, too, the data recovery solution lies in a creative marriage of the technological and the human. The underlying philosophy of successful data recovery is that technology is something to be used by human beings, not something that uses us.

The video gaming experience is different for everyone, it could end in hours of entertainment for a family or for the less experience, the final result could be disappointment due to lack of knowledge of how to operate the game console. When you are shopping for a new game console, you may find it difficult as there are so many different options to choose from. The information you are looking for can be very difficult to find, but you will find there’s a lot of misinformation out there.

First off, here are some questions that you need to ask yourself and you should keep in mind while reading:

-What are the types of games that interest you?
Do you plan on buying an HDTV anytime soon or do you already have one?

What type of budget do you have to work with?

Do you prefer multi-player games, or single-player games?
Have you got any of the old school gaming systems?

The PlayStation 3 was the most pricey for quite a while. Fortunately, prices are lower now than at that time. For only 400 USD (it all depends on the model you plan on buying)this price is more comparable. Prices change constantly so chech the latest video games console prices online.

The PS3 is an experience, it is more than just a game console. As it’s compatible with Blu-Ray, CD, and DVD media, it also has the ability to play DVDs in HD. The PS3 would be perfect for those with an HDTV and no HD movie player as you can get both of your movie and gaming experiences in the same box. This is with the latest technology of Blu-Ray, the leading high-definition movie format. Without an HDTV display, movies in Blu-ray format don’t provide any better quality. This feature doesn’t translate well for use with a standard definition set.

While virtually the same as the PS2 controller, the controller features motion sensing technology known as Sixaxis. The controller, which can be tilted in six different directions, is able to sense which of the directions to which it has been tilted. How well this is going to work varies from each game. Doing it well means you’ll gain lots of experience, doing it wrong means you’ll be nothing more than a problem. You need to keep in mind that the Sixasis controller is missing the vibration feature. The DualShock 3 controller with vibration will not be included with the new PS3’s, even though it has been released, until June 12, 2008.

Video games for the PS3 and Xbox 360 are pretty much the same the same for either system.

Are you ready to get your laptop battery to last for a while? Understanding what type of battery you have and how to care for it can go a long way toward that goal. Steps that will extend the life of one type of rechargeable battery will kill another type of battery. Being knowledgeable on the type of laptop battery you own can go a long way towards being able to use your laptop battery for a long time to come.

Know What Kind of Battery your Laptop Uses

The three most common rechargeable batteries on the market include lithium ion, nickel metal cadmium, and nickel metal hydride. Most laptop batteries today use either lithium ion batteries or lithium ion polymer batteries for a number of reasons. You can confirm this by pulling your laptop battery out from the bottom or back of your laptop and examining the tiny writing on it. Look for something that says either lithium ion, nickel cadmium, or nickel metal hydride.

Advantages of Lithium Ion Batteries

The most common battery in modern laptops uses lithium ion technology. This battery has a number of advantages over the other types of rechargeable batteries. I’ll list them below:

Lithium Ion Batteries don’t develop a battery memory. Both other types of rechargeable batteries can develop a ‘memory’ for shorter charges drastically shortening the amount of time your battery lasts between charges. Lithium Ion batteries though, don’t suffer from memory problems.

Lithium Ion Batteries hold their charge for a long period of time. The other battery types will lose their charge if left to sit around even if they aren’t being used. Lithium Ion batteries will hold their charge for a lot longer between charges even if the battery ends up sitting around for a while.

You get more battery life than the other rechargeable types. For the same size and weight, lithium ion batteries last longer between charges because more of the bulk of the battery is dedicated to capacity rather than just ‘overhead’.

For information on the disadvantages of lithium ion batteries, check out printerinfosite.com.

Quick Way to Kill Your Lithium Ion Battery

Avoid the following list of things in order to get the maximum life out of your laptop battery. Some of the most common things to avoid include:

Do not subject your battery to extreme temperatures. Lithium ion batteries do not handle heat well. One of the quickest ways to kill your battery is to leave it in a hot car even for a short period of time. In fact, if you aren’t going to use your battery for awhile, you are better off storing it in the refrigerator but NOT the freezer, that will kill it too.

Avoid completely discharging your battery where possible. While other types of rechargeables like nickel cadmium batteries need to be completely discharged, doing this with lithium ion batteries will kill it. As much as possible, recharge your battery when it has around 40% of its battery power left. Recharge often.

What’s Your Processor?

First and most important thing to consider when buying your motherboard – what CPU or processor are you using? Motherboards are made differently, not all motherboards will support all CPUs. What CPU you select will determine the type of motherboard you get.

For example, if you want to use an Intel Pentium 4 CPU, the motherboard you select must be able to support that brand and model of CPU. The motherboards are also designed to support specific speeds for a CPU, so make sure it can support the speed of the processor as well.

Choose Your Chipset

What is a chipset? Well, chipsets are the main controllers on the motherboard – they allow the CPU to interface with the various components and expansion cards installed.

When choosing your chipset, always bear in mind the type of memory supported by the motherboard. Make sure that the board supports the type and amount of RAM you need. Generally, choosing a chipset that supports high speed memory will allow your system to perform better.

Expansions Slots and Connectors

If you intend to various peripherals to the computer, then the number and type of expansion slots and connectors is important. By default, most motherboards these days have USB 2.0 ports incorporated into their design. If you do a lot of video capturing and editing, you’ll also want to have a Firewire (IEEE 1394) port. If you intend to buy expansion cards, make sure the board comes with an ample number of PCI slots.

Do You Need to Overclock?

If you want to overclock your CPU (though I don’t particularly encourage it) – you should ensure you get a motherboard that supports overclocking. You’ll want a motherboard that has a wide range of adjustments to CPU settings, including CPU voltage and bus speeds.

Other Features

These days, most motherboards have a whole host of extra features loaded into them. These can include things such as on-board Ethernet, audio, a RAID controller or even graphics. I find such features very handy as they help you save money – you need not buy additional expansion cards.

Conclusion

In short, make sure you do your homework when purchasing a motherboard. Go to the motherboard manufacturer’s website and read about its products. Download the motherboard manual and see if its well documented.

At the risk of sounding biased, I’ve always preferred ASUS motherboards. However, its all up to you. Consider what features are important to you and go get your motherboard. As I said earlier, don’t scrimp on the motherboard. Its one of the most important PC components, so get the best you can afford.

The USB standard has become the universal means of connection peripheral devices and equipment to the computer. Computers have either two or four USB port connectors. Each of these can support a large number of connections but to be able to attach more than two or four devices requires a multi-connection hub. There are many different types of hubs and this article seeks to explain some of the important considerations in selecting the best choice of hub for your system.

The USB bus system in computers was introduced in 1996 and has gone through a number of developments and enhancements. It started out as USB 1 which was very slow and had many bugs. Version 1.1 brought a higher bandwidth of 12 MBits/second. The latest version of 2.0 gives a bandwidth of 480MBits/second and is fully backward compatible with USB 1 and 1.1.
Link to a table showing differences between USB speeds (http://www.usb-products.com/usb-speed.aspx)

Port Connections and Power
All USB standards support up to 127 connections (or devices) per computer port. It is unlikely that this would be achievable as the port can only supply 0.5 Amps maximum. Some devices consume a full 0.5 Amps, so are powered from a power adaptor from the mains supply.

Bandwidth Sharing
Generally, the bandwidth of the port (http://www.usb-products.com/usb-port.aspx) is shared between all the devices that are attached through a hub. This means that if you want to add two USB 2 devices with a USB 1.1 device, the bandwidth is shared between all three devices. However, there is an extra complication. Most hubs (http://www.usb-products.com/usb-hub.aspx) have a single chip controlling the bus. This means that the hub will work at the lowest bandwidth determined by the connected devices resulting in the USB 2 devices working at much lower transfer speeds. Nearly all USB hubs on the market today (passive and powered) operate like this.

Multiple Chip Hubs
The transaction translator (TT) is the name for the controlling chip that assigns bandwidth to each connected device. In hubs that have one TT all devices share the same bandwidth and operate at the speed of the slowest. In hubs with a TT per socket, each receives a share of the bandwidth, but this is not restricted to the slowest device.
Examples of this type of hub is the Belkin Tetra hub (http://www.usb-products.com/Products/Hi-Speed-USB-2-0-4-Port-TetraHub.aspx) This has 4 ports each with its own TT.

What this means in reality is that a multiple TT hub will provide much higher bandwidth per port when several devices are connected from one hub.

Maximum Performance and choice of Where to connect a device
If you are after maximum performance for each of your USB 2 devices, each device should be plugged into its own USB port in the computer. Additional plug in cards can provide a vast number of USB ports for most needs. However, this situation might be going too far except for the most demanding of situations. Although several USB devices might be connected at the same time it is unlikely that they will all be in use together.

A useful compromise is to plug small bandwidth devices together into a single hub. These would include: mice; keyboard; Speakers; little used devices.

For devices that require a high bandwidth and are used often, direct connection in to a USB port is the best option. Devices would include: Flash memory drives; external disks; Web cams; Other frequently used devices.

If you don’t have sufficient ports then either more ports should be added with a plug-in card or a good quality hub with multiple transaction translators should be used. The devices placed on the hub are those that are used less often. Those devices placed directly on the port are used most often.

Link to a selection flow chart that helps in selecting a hub (http://www.usb-products.com/USB-Hub-Selection.aspx)

Access Considerations
What type of configuration and mix of port and hubs will depend on the number of devices that you wish to attach. Desktop computer cases usually have ports in the front of the case for easy access. These can be used for devices that are often plugged / unplugged and require the highest bandwidth. These are flash memory drives and portable external drives and MP3 players.

USB hubs tend to clutter up the area with cable connections and power lead. These naturally go out of sight if possible or behind the monitor. For mobile computers, a small compact hub can be obtained. These may have there own wind-in or tidy away cables.

Powered and Passive Hubs
Hubs may be restricted in their use without a power connection as passive hubs rely on the power of the USB bus. Powered hubs have a mains power adaptor to provide additional power for devices. These devices range in the power they require. It is possible to run a number of different devices all from a single passive hub running of a USB port as long as they have low power requirements. With only 0.5 Amps current it only takes one of the devices requiring the full power requirement for the hub to be overwhelmed. Nothing serious is going to happen though except that the single will degrade and many or all the devices will loose connection with the computer. To avoid this situation a powered hub should be used.

The article summarizes the Hyperthreading technology as best as possible in just ten steps.

1. Hyperthreading (HT) is term coined by Intel for Simultaneous Multi-Threading (SMT).

2. Hyperthreading is meant for dual-core or multi-core processors like Pentium 4 with HT or Xeon MP.

3. The technology aims at better utilization of execution units in a processor which otherwise would be idle.

4. This technique is better than its predecessor Multithreading and Superthreading in the sense that in each instruction cycle, a processor can execute instructions from mutliple threads.

5. Hardware implemetation of Hyperthreading is not very complex as reported by Intel “Implementing HT took only 5% more die space in Xeon”.

6. Implemeting HT needs hardware resources to be divided into Replicated(e.g. Instruction Pointers), Partitioned (e.g.Queues) and Shared (e.g. Caches)

7. For actual performance gain, your applications have to hyperthreaded i.e. you have to parallelize your code.

8. Hyperthreaded applications use Shared Memory Programming Model. Most famous Shared Memory Programming standard is OpenMP (Open specifications for Multi-Processing), an effort initiated by Silicon Graphics Inc. and now supported by major industry players. OpenMP library is available for C,C++ and Fortran on both Windows and Unix platforms. OpenMP programming constructs consists of few compiler directives for parallelizing the code.

9. There are compilers and other automating tools that support shared memory parallel programming libraries like OpenMP. Some examples are Intel C++ Compiler, Intel VTune Performance Analyzer and High-Level tools from KAI Inc.

10. Hyperthreading does not necessarily increase performance. With wrong mix of code, it can even decrease performance.

PCs have become a staple in every home. Without PCs, you will find it hard to stay connected and to even do the work required of you in school or in the office. With so much PC packages being shoved to our throat every time we go to department stores and computer shops, you’ll really get quite confused on what you really need and what PC package will fit your budget and lifestyle. To help you through this dilemma, here is a brief backgrounder of the parts of PCs that you should get to know.
Processor.
This is one of the three primary components of your PC. The processor is the part that determines how fast your computer process information. Intel is still the leading brand in processors but competitors such as American Micro Devices (AMD) are slowly catching up, offering cheaper alternative. In shopping for a processor, one should consider the following:
Clock speed – this will show the number of instructions that a computer can execute in a second. This usually comes after the brand name. Processors nowadays are already set at the gigahertz range.
Cache memory – this stores the data that were previously accessed. This simplifies the work of the computer as it would not take twice as long to access information already stored in memory bank. Without a cache memory, much of the work will fall on the RAM (Random Access Memory).
Operating temperature – some processors easily heats up. Before buying, make sure that you have asked about the operating temperature just in case you need to buy additional fans or put the computer in an air-conditioned room.
RAM (Random Access Memory).
RAM serves as the temporary memory of the PC, containing information that are needed for the computer and the programs to function. In addition to processors, RAM also determines the speed of the computer. The higher the RAM, the faster the computer is in accessing information and responding to commands.
Motherboard
This is where all the parts of the PC’s CPU (Central Processing Unit) are attached. Some motherboards already have videocards and soundcards embedded on it while others don’t. what is important however is to choose a motherboard that is compatible with your RAM and processor. Incompatibility of PC hardware can cause major problems and may even lead to the breakdown of your computer.
Hard drive.
This is the part where you store all the information in your PC. Picture a floppy disk with much much larger storing capacity. The hard drive serves as the permanent memory of your computer. Here you install all your programs and save all the documents that you need. It is also important that you buy a hard drive with really big capacity especially now when people are so used to storing multimedia files that may use up a lot of hard drive space.
Video cards
This is the part of the computer which determines the quality of the multimedia images that you will view. The higher the memory of the video card, the better is the picture quality and the colors. Also, video cards are also responsible for how fast multimedia images are accessed. This is especially needed if you use your computer for multimedia activities such as watching a movie or playing video games.
