This time I will try to discuss about the USB (Universal Serial Bus). Currently, almost all computers have USB connectors are provided on the CPU it. This type of USB connector can connect with some hardware to your CPU. Moreover, its operating system also supports a USB connection, making it easier to install quickly. Some equipment already using USB: Printers connected to parallel ports, and most computers come with only one type of connection. Such as Zip drives, which require high speed when connected to a computer, usually using the ports parallel ports as well, very often face problems with limited speed. Modems used the serial port, as well as with some printers and various other things such as Palm Pilots and digital cameras. Most computers have at most two serial ports, and they are very slow in many cases. Devices that require faster connections came with their own card slot, which of course requires a match to get into the card slot inside the computer case. Unfortunately, a limited number of card slots USB goal is to end all the complexities. Universal Serial Bus provides a single, has created a standard, easy to use to connect up to 127 devices to a computer. Examples of devices that are using a USB connection:* Printer* Scanner* Mice / Mouse* Joysticks* Flight yokes* Digital camera* Webcam* Modem* Speaker* Video phone* Storage devices, drives sepertiZip* Network connectionsAlmost every computer you buy today comes with one or more Universal Serial Bus connectors on the back. These USB connectors let you attach everything from mice to printers to your computer quickly and easily. The operating system supports USB as well, so the device driver installation quick and easy, too. Compared with other ways of connecting devices to your computer (including parallel ports, serial ports and special cards that you install inside the computer case), USB devices are simple amazing!

There have been a number of wonderful inventions during the 20th and 21st century. Some of these creations have been both massive and minute. Very few of mankinds modern creations have revolutionized working life so much as the USB flash drive though. Ok now that might seem a bit much for some people but the reality remains the same – USB flash drives have made the working lives of millions of office workers, teachers, students, IT and other professionals massively more simple. If you already one (or a few) USB flash drives then you’ll know just how incredibly useful they are. If you don’t already own at least one USB memory stick then hopefully this article will help convince you of their absolute usefulness in both your working and personal life. So what’s so great about USB flash drives?SmallPrior to the creation of USB flash drives all external storage devices for computers were either bulky or awkward (dozens of blank discs for example) or sometimes an annoying combination of being both bulky and awkward. USB flash drives are also called Thumb Drives because they’re about the size of your thumb (although some are much smaller now) and you can easily fit several gigabytes of data in your jeans or shirt pocket thus eliminating the bulky and awkward factor straight away. PortableUSB flash drives are about the single most portable data backup device possible. They don’t require an external power source of any kind, nor do you need any cables or tools to set them up and last but not least they don’t require any additional software to be installed for them to work on any modern computer (Windows XP, 2000 and Vista and most Macs) so you can quite literally pick them up and use them anywhere you want. ReliableOnce the data is stored on a USB flash drive you can rest assured that it’s going to stay there and be there when you next need it. This is totally unlike the world of floppy disks or rewriteable CD/DVD discs where they can just stop working for no apparent reason. Flash drives were built to provide consistent and reliable performance. Most of these drives come with built-in write protection to prevent you from overwriting your own important data – if you were silly enough to do so. ToughFor years people fiddled with boxes of floppy disks and CDs/DVDs. These were bulky, easily lost and easily damaged. External hard drives also provided another method of transporting data between systems but the smallest jolt was and is enough to kill an external hard disk stone dead. USB flash drives are based on what’s called Solid State Memory – this simply means that it’s the same as standard computer memory in that it has no moving parts and is therefore almost impossible to damage (except for jumping up and down on it or maybe hitting it with a hammer for example. Please don’t test either of these theories at home!)Mass StorageThe first USB thumb drives only offered between 16MB and 64MB of storage space. The incredible popularity of these drives has driven the desire for more and more storage space to new heights every few months. Currently 8GB USB drives are becoming pretty common and it won’t be long before the 12GB and 24GB models hit the market. To put this in perspective 8GB is enough to hold 2 full DVD quality movies or about 2,700 high quality MP3 files – surely this is enough for you? No?The portability of the USB flash drive combined with reliability and the more than generous storage provided by such a tiny device make them the smart choice for anyone who needs to move files between PCs or simply just keep a second copy of their most precious data on a secure and reliable storage device.

These days, all forms of communication technology face the problem of security and theft of personal details , and ‘bluetooth’ is no exception to these concerns, nor should it be. Most everybody knows by now that all email programs and networks need protection and security. What users of ‘bluetooth’ really do need to comprehend is that ‘bluetooth’ requires the same protection measures as email programs and other communication programs.
The upside for ‘bluetooth’ users is that the recent breaches-of-security scares, as in all scares, are usually way over – dramatized and blown way out of all reasonable proportions. The reality being told, these issues are simple to control, using several protocols now in place to ensure protection for ‘bluetooth’ technology.
It’s very true that there has been several ‘bluetooth’ phones subject to attack and have been hacked into. The majority of devices which are hacked are usually those that don’t use any form of protection or security at all.
Bluetooth specialists say that, in order for anyone to hack their way into a ‘bluetooth’ device, the person hacking has to:
1. Convince two coupled devices to shut down their link.
2. Take the packets that are required to resend the pin.
3. Unscramble the pin.
Of course, the hacker most certainly will be within limit of the phone, and using extremely costly developer – style , high quality, equipment. Top specialists strongly suggest you use a longer pin, using more than 8 digits as being the minimum recommended.
Basics of security.
The “pairing procedure” is the main fundamental level of protection for ‘bluetooth’ devices. Pairing, is the linking of two, or even more, ‘bluetooth’ devices which identify themselves by the profiles they have in common – in the majority of cases they both must use the identical pin.
The central specifications for ‘bluetooth’ use an encoding algorithm, that is is absolutely and safe and secure . As soon as the devices link up, they too become completely protected.
Until they have actually linked, the ‘bluetooth’ devices won’t make contact with each other. Due to the pairing technique and that the range is very short it is – ‘bluetooth’ technology is thought to be well and truly secured.
As the recent news has shown, expert hackers possess sophisticated ways to get past most levels of fundamental security. There are ways to get protection from this type of threat, as you can have installed software to stop hackers from hacking their way in.
Now that ‘bluetooth’ has become popular and more in demand, it’s no wonder safety is constantly in the public eye. As ‘bluetooth’ gets more popular and more improved, security can usually be something that no one will ever take lightly.
If you’ve been thinking about ‘bluetooth’ protection in the past, be safe in the knowledge that newer devices can give significant and much-improved protection. Stopping hackers from creeping in is something every phone-owner is thinking long and hard about – and the maker’s are very much aware of this.

Unlike laptops, desktop PCs have various components that need to be purchased and you may need to look at each component and decide on the specifications before you make your final choice. Making an informed purchase decision when you buy desktop PCs can hold you in good stead later. Some of the components of desktop PCs and factors to consider have been mentioned below. CPU or Central Processing UnitIn most cases the choice that you have in desktop PCs with regards to the processor is Intel or AMD. The processor dictates the speed of the computer based on the number of cores that it has. Memory or RAMThe latest memory unit that is now being used in all desktop PCs is called DDR3. The older DDR2 technology is only used in cheaper, budget desktop PCs. The amount of memory that you may need depends on what you intend to use the desktop PCs for. If you plan to play high end games or do some major multimedia graphic work you will need a memory that is higher than 4GB too. On the other hand, if you want to use only basic spreadsheet and document applications a 2GB memory may also prove to be enough. DrivesMost desktop PCs use 7200rpm hard drives these days, though high end 10,000rpm hard drives are also available. At least a 500GB storage space is best. DVD burners are an essential part of all desktop PCs and Blu-ray is also becoming popular. MonitorDesktop PCs use LCD monitors now and the older CRT monitors are hardly used. Today the price of a 22-inch and a 19-inch is not much, making it the best choice for desktop PCs. There are other aspects like external connectors and video cards that you might also want to consider when you make the purchase for desktop PCs.

Do you ever ask yourself, what happened before we had cell phones? Then you think back and remember how it all started. First we had the beepers where we had to pull over and call our friends from a pay phone. Then the first cell phones were created. I remember in the 90’s I had to carry around a big fake Louis Vuitton purse so I could fit the phone inside. It was a huge phone with a long black antenna that didn’t fold in. Now we have cell phones that keep getting smaller and smaller and smarter and smarter. Our cell phones are so smart we don’t even need keypads anymore. We now have smart phones with a <a onClick=”javascript:pageTracker. _trackPageview(‘/outgoing/article_exit_link’);” href=http://www. cirque. com/uploads/products/touchpad. html>touch pad</a> and <a onClick=”javascript:pageTracker. _trackPageview(‘/outgoing/article_exit_link’);” href=http://www. cirque. com/uploads/products/touch_screen_panel. html>touch screen panel</a> technology that allows us to access the internet, map out directions, take photos and video, listen to music, watch movies and even update our social media websites. Its technology at its fines and here are two mobile phones that are leading the innovation of cell phone technology. The iPhoneApple announced the iPhone in January 2007. This phone is a multi-media smart phone with a multi touch screen panel. The cell phone is one of the first to implement a virtual keypad on a touch panel screen instead of a physical keypad. It was also one of the first phones to offer visual voicemail along and iTunes capabilities. When caller ID came out I bet 90% of people started screening their phone calls. Now with visual voicemail you can screen the messages you want to listen to and even listen to them in the order you want. With iTunes capabilities your phone is also a mini iPod that you can plug into your car or strap to your arm for a run. It’s completely flexible. The only thing Apple missed on the launch of the iPhone was GPS capability. But, not for long in July 2008 Apple introduced the new 3G iPhone. The 3G iPhone was faster, smaller, cheaper and had GPS capabilities. Both phones synch easily to your computer for software updates that keep making the phone better and better. The iPhone paved the way for advanced cell phone technology. 5800 Xpress Music Nokia is getting ready to unveil the 5800 Xpress Music mobile phone by year’s end. The new device was designed to give Apple’s iPhone some competition. Along with the iPhone the 5800 will have touch screen panel technology and music capabilities. Per an article from PC World the similarities between the two phones stop there. The Nokia’s touch screen virtual keypad will also work with the touch of a fingernail or stylus unlike the iPhone which uses the touch of your finger pad. The new Nokia went after a more user-friendly software approach as well. Some of the features include a contact bar with photos of friends that you most frequently contact that you can send text messages from. And, going one step further than the iPhone, you can also add feeds to your phone that will alert you when friends update their social networking websites. The new Nokia also supports flash software another element the iPhone does not have. Other cool features include video capture, handwriting recognition and louder surround sound speakers. And the best part about the phone is the cost. The new Nokia will cost half the price of the competitive touch screen phones in the market. We’ve come a long way from beepers and large cell phones. With the advance in technology we can purchase not only a cell phone but a smart cell phone that doubles as your PDA and iPod and it’s small enough to fit in your pocket.

As with the motherboard, there are several beep codes relating to faults with graphic cards. The situation here is further complicated by the fact that some of these codes can also imply problems with the system memory. Assuming there is an AWARD BIOS and a sound of one long beep and two short beeps, this would indicate a problem with the graphics card with a less likely possibility of a fault in the memory.

All it can really do is check out the possibilities in the order of likelihood. Unfortunately, for the average PC user suspecting a fault specific to a board, the options are limited. Unless some specialized test equipment and the knowledge to use it, following procedures are basically restricted by the manufacturers to the following; check the connections by re plugging the card into its socket. If there is an availability enough to have a functional graphics card handy, perhaps from an earlier upgrade, try installing that card. If a card is not present, consider going out and buying the cheapest one you can find, as submission is the only way to be really sure.

Resource Conflict could have a situation whereby your graphic card is OK but is being prevented from working by another hardware device which is claiming the same system resources. The usual method of sorting out this type of problem is by using the Device Manger in the Control Panel. This however, requires access to Windows, which in this situation you obviously haven’t got. What you’ve got to do therefore, is one by one, physically remove every device in the system, restarting each time and seeing if the pc now boots. If and when it does, then the last windows go into the Device Manager to resolve the issue.

Find out how to solve this in the Resource Conflict Troubleshooter. Help is available in most of the operating systems to trouble shoot resource conflict. Increasing the space for the new hardware could solve some of the problems. It’s surprising how many problems can be caused by loose or dirty connections.
