USB (Universal Serial Bus) is a low cost interface connection. It is now the most common computer connection with many devices such as keyboards, printers and digital cameras using it as standard. As the number of compatible devices has grown the need to easily access them has also increased. This has meant many users now need to expand and extend the USB connectivity of their laptop or desktop computer. Expanding allows devices to be shared, split and accessed by more than one computer or enabling a computer to connect to multiple USB devices at the same time. Expanding overcomes the problems of the limited number of USB ports often supplied with modern computers, especially smaller laptops and netbooks. Extending increases the distance USB signals can be sent so a computer doesn’t have to be closely situated to the peripheral. This combats one of USB’s major limitations in that the standard maximum recommend length for a USB cable is 5m due to performance restrictions. However, for some applications for example interactive whiteboard installations, 5m is not always enough so signals need to be extended.
The most common method of expanding USB is through the use of simple USB hubs. Hubs allow multiple USB peripherals to be connected to one USB port. Hubs in turn connect to a host computer transmitting all connecting signals to it. The problem of port congestion is then solved as hubs generally have anything from 2 to 8 ports. Hubs are commonly free standing but are also built into devices such as monitors.
USB switches expand peripheral connectivity by allowing them to be shared with multiple computers. They are a cost effective solution especially useful for devices which need to be accessed by more than one computer, such as printers. They eliminate the need for duplicate devices and multiple cables. Switches alternate between computers as the users decide who has access to the equipment at that particular time.
USB sharing hubs combine the functionality of both a hub and a switch and can serve multiple USB devices between a number of computers at the same time. Just like switches, sharing hubs are ideal for larger, more expensive equipment that needs to be accessed by more than one person at a time, but with the capability that allows users to do this simultaneously.
As with expanding, extending USB can also be achieved using a number of methods. A simple way of extending USB is by using extension cables. USB extension cables are useful for extending devices over shorter distances and typically max out at around 3m in length. The ‘plug and play’ capability of extension cables makes them a simple and easy to use solution. They work with both smaller and larger devices such as card readers and printers. USB extension cables are ideal for use with wirelss dongles or with products that have built-in USB cables.
A simple, cost effective way to extend USB over very long distances is by using Cat.5 USB Extenders. As their name implies, these devices use standard Cat.5 Ethernet patch cable to make the long distance connection. A transmitter is connected to a computer via its USB port while a receiver connects to the USB peripheral at the opposite end. The two units are then connected using Cat.5 cable. Commonly used with devices such as interactive whiteboards, extenders are a great solution for connecting devices further away from a host computer than an extension cable would allow. Distances of up to 50m can be achieved; however, USB 2.0 is not usually supported so devices are limited to USB 1.1 performance of up to 11Mbps. Cat.5 USB Extenders are probably the cheapest and easiest solution for connecting a USB device and host computer over great distances.
Perhaps the ultimate form of USB extension is USB over IP servers which allow USB devices to be connected to a network. Equipment such as a standard USB printer can be transformed into a shared network device as the server provides an interface between the device and a network. It simply connects the device to a network via Ethernet so the device can be used by anyone on the network wherever they are in the world!

With the ever expanding market and the growing craze for latest technology, the mobile phone market in UK is emerging as never before. The market is being flooded with numerable brands, latest handset designs and some very good service providers such as Vodafone, Orange, O2 etc.
The mobile phone industry is growing at an enormous pace with the trend expected to continue in the coming future.
Improved cameras, enhanced memory, sleek body and much more have become the usual characteristics of mobile phones these days. Now the quest is to create the thinnest of the handsets and the new mobile phones that would come in to the market would be termed as wafer thin. The term also suggests that apart from being very narrow in width, the mobile phone handsets will also be much lighter in weight than before.
The mobile phone manufacturers and designers have been successful in understanding well the needs of the customers and then developing hand sets around those needs with features that cater to each of those needs. For instance they realised that it is a tedious task for an individual to carry a digital cameras, an mp3 player, a mobile phone, and other similar devices while travelling. Keeping this in mind they embedded all these features in the mobile handsets which resolve the problems of carrying too many gadgets. Internet access and data transfers through infra red and Bluetooth enabled mobile phones have become a common feature in terms of utility for the consumer. Such integration of functions was one of the first step towards design development for mobile phones, the next step that is still being under taken in this direction is that towards enhancement of these integrated functions such as higher data transfer speed, higher mega pixel cameras to improve clarity, mobile phone compatibility with printers and so on. Such emerging trends come into picture after various mobile phone companies undertake research and development at a continuous pace. Newer technologies keep coming out at a result and mark improvements over the existing ones. Consumer remains the main beneficiary of all these efforts.

Due to many requests I will discuss virus removal. This is of great importance these days as newer and nastier viruses are being released all the time. The best offense is a good defense so it is imperative to have
anti virus protection. If it is too late to protect and you already have a virus read on.
As I said, the best offense is a good defense. Of all the software you buy the one you should not skimp on is an anti virus program. I have heard several stories recently of people paying $350.00 to have a virus removed and the operating system reinstalled. This really doesn’t make any sense because installing an operating system requires formatting, (erasing), the hard drive which would eliminate any viruses contained on it anyway. Protect yourself first and avoid being put in that position.
Once you are infected you must act quickly. Delay will just allow it to change more of your system settings. If the virus gets into the root of your system it can be very difficult to remove. This is called a root kit virus and they attach themselves to necessary system files. With that being said I suggest that you proceed with caution because deleting the wrong files can cause great damage to your system, sometimes so bad you are unable to boot up at all. Here are links to two free root kit anti virus programs. The first is from Sophos. I haven’t used it yet myself but they do have good reviews. . .
http://www.sophos.com/products/free-tools/sophos-anti-rootkit.html
The second is from AVG and I have used this one. It is fast, thorough, and free. Here is the link to this program. . . .
http://www.softpedia.com/get/Antivirus/AVG-Anti-Rootkit.shtml
Before you use a root kit anti virus it is imperative that you disable ALL real time scanners from your anti virus, spyware, and adware removers as well as your firewall. Use extreme caution when you choose to delete anything a root kit anti virus finds. If you are unsure about what to do go to this link and look up what the program has found to verify if it is a virus or not….
http://www.f-secure.com/en_EMEA/security/security-lab/latest-threats/virus-descriptions/
Before you begin scanning for spyware follow this tip. Use a cleaning program to clear out junk files and temp files first. It will cut down on the scan time for your anti virus. Don’t forget to purge your temporary internet files and cookies too. You also need to make sure your programs have the latest updates.
Here is what I do when I am presented with an infected computer. I will run two anti virus programs, one at a time. I will scan two or three times with one until it doesn’t detect anything anymore, then I will uninstall it including the virus vault. Then I install a different anti virus and run it several times, the choice of programs is up to you. Here are two other options for you. Get Microsofts free malicious software removal tool from this link.
http://www.microsoft.com/security/malwareremove/default.mspx
I also run Spybot and Adaware afterwards just to make sure I got everything. Spybot is for spyware but it definitely will find a virus too.
Once you think you have found everything I suggest making sure. There are a few sites that offer online scans. The only one I have used before is Kaspersky and it is free and thorough. You just go to the site and let it scan. At the end you will get a report that shows any malware left on your system. Here is the link..
http://www.kaspersky.com/virusscanner
After removing any viruses from your computer it is always a good idea to clean it up. Use your cleaning utility to clean the system and registry. After that run your defragmenting program. You should now be at a nice clean system state. This is the perfect time to set a restore point and use your backup program to create a new backup. You do have a backup program don’t you?
