If your computer has just been getting slower and slower since you bought it and mistakes are becoming more frequent, it's prison term for a tune up. This means running the latest updates, using certificate applications and on a regular basis maintaining your computer and a good deal more. Your computer can communicate with thousands of different devices but it can only do so using device drivers.
What clients have wanted, but more significantly needed, over the past classes has changed substantially. As businesses become leaner and headcounts reduce, so priorities and their drivers have altered. So called "Have-to-haves" or essential requirements are the issues ones getting any traction, relegating "Nice-to-haves" to the back-burner until they either become irrelevant or are escalated for other grounds.
Many devices need to be apportioned an area of memory to shop informations and or a Direct Memory Access (DMA) channel. A DMA channel allows a device to make a data stream directly between it and the computers memory without passing through the C.P.U..
The motherboard is the heart of the computer, every portion of the computer relies on the motherboard to work right. It maintains connection between every PERSONAL COMPUTER component and ensures that things are operating smoothly between them. Many marks of motherboard failure is that the computer won't kick up, not reaching the STATION test, erratic system behavior, different combinations of portions not working. Because everything is linked up to the motherboard certain parts may or may not work right if the motherboard is defective so be sure to try out those parts before thinking they 're dead and getting new ones.
The condition software is generally used for computer software that is an essential office of the computer system. It shops and procedure all encoded data or computer instructions on PERSONAL COMPUTER. Computer software has very vast scope in computer world.

External hard drives
We have all heard the term phrase external hard drive, yet some may still not fully understand what that phrase means. By definition an external hard drive is basically a drive that is not found inside the pc rather, it is often connected to a laptop or pc by means of an external connection. In other words the external hard drive is found outside the pc tower. The individual can transport the external hard drive without having to reopen the pc to retrieve the device.
The advantages of external hard drives over the normal internal drives are portability, accessibility, and independent nature. External hard drives are not found within the pc, rather the drive is connected to the pc with a network cable. Any time the user wishes to use the external hard drive, he/she can simple connect the drive to the working pc. This feature allows the user more hard drive capacity for files, music, and other media forms. Should the individual need the saved files again at another location, the individual can simple take the external hard drive with the saved data and connect it to another pc. This ability to move around important data is a key feature of external hard drives.
In terms of accessibility, the stored files on the external hard drive can be accessed by any machine the user wishes to connect. For example, the individual may wish to copy certain files he/she had been working on at a home pc to the pc in the office. External hard drives permit such accessibility to off site files.
Another important advantage of external hard drives is its independent nature. If the internal hard drive becomes infected by roaming computer viruses or the drive just dies for no reason. The external hard drive will not be infected by any destruction or damage to the internal drive, therefore files and documents copied onto the external hard drive will be safe and secure should something happen to the internal one. As safety becomes an ever growing concern on the Internet, external hard drives can be used to store sensitive material separated from Internet access. This allows with the use of backup software, the user to maintain sensitive documents and files from possible Trojan and spyware attacks.
Although there are many advantages in regards to using external hard drives, one must remember that external hard drives are hard drives with specific capacity, shelf life, and vulnerability to viruses and damage. External drive does not infer that it is immune to the factors that can cause damage to internal drives. The computer user will still need to be cautious when working with external drives.
External hard drives are easy to purchase as they can be found at any computer store or on the Internet. Some brand names include Seagate, Samsung, Iomega, Western Digital, and Toshiba. Prices will vary, depending on the brand, design, capacity, performance and any other added feature such as USB support. Often the prices of external hard drives range from under 100 dollars to well above 200 dollars. Again it will depend on the features the user is looking for in an external hard drive.

Sony AIT-5 Backup Tape Devices
Today’s modern data rich IT environments need faster and higher capacity solutions, which can ensure long term preservation of critical business data within their limited budgets. The organizations require high performance storage mediums that are user-friendly, shorten the processing time, offer highest levels of data security and support automated systems. The role of tape storage technology has gone under significant transition from simple data security to more write-once archiving.
According to the survey conducted by IDC (international data corporation), during the first quarter of 2006 the revenue generated from the mid-range and small business market was many times greater than that of Enterprise market segment. This increased storage demand in the SMB segment influenced Sony to increase the capacity and recording performance of its next generation AIT-5 tape format.
Sony AIT-5 tape drives provide unmatched data accuracy and economical backup solutions for the data rich applications. AIT-5 is the most advanced and latest generation in AIT lineup. New Sony AIT-5 tape features 400GB capacity. Good news is that the data compression capability of AIT tapes is greater than the traditional drives. AIT tape drives reliably carry out the data compression process at 2.6:1, which means that the compressed storage capacity of AIT-5 cartridge reaches 1.04 TB. Backward read-write capability of Sony AIT-5 drive includes prior 2 generations AIT-4 and AIT-3.
For regulatory compliance, the most reliable and efficient WORM (write once read many) technology has been employed to the Sony AIT-5 products. The size of Sony AIT5 tape is approx. one third the size of other competing tape technologies of similar capacity, which makes it more space efficient. Sony has intelligently reduced the tape length by 40% and has increased its areal density to store more amounts of information. Increased bit density has helped to improve the signal-to-noise ratio.
Sony AIT-5 drives feature unique dynamic tracking read/write head that assure extremely precise data reading and recording in the narrow track paths. This also helps to boost the searching speed and provides exceptional tape stability. The best cleaning cartridge you can use with Sony AIT-5 drives is SDX5-CL AIT cleaning cartridge.
Sony has used AME-III media formulation that has significantly enhanced the smoothness and uniformity of AIT-5 tape’s storage media. Smooth tape reel helps to lower the friction when it comes in contact with the head, thus extending its working life to 30,000 tape passes. You can reliably use the following AIT tapes with Sony AIT-5 drives:

SonicWALL SonicPoint Ideal Solution
SonicWALL SonicPoint-N Access Point Devices meet all the security requirements you need in implementing the wireless networks in your businesses. Supports dual-band Exceptional Wireless Performance with business class features including WPA/WPA2, SSL VPN, Wireless Intrusion Detection Services (WIDS), wireless firewalling, secure Layer 3 wireless roaming, and integrated Wireless Guest Services (WGS).
Implementing wireless access in business class networks needs a thorough risk assessment regarding the security issues that may arise. This is reasonable since, unlike wired security which is physically secured, wireless networks are not confined to the inside of buildings. Wireless security is inherently easier to crack than wired networks because there's no need for a physical connection to your network. Data transfer occurs over the airwaves, and that makes accessing it easier.
Firewall with the intrusion detection systems are typically deployed in each of the perimeter networks which face direct to the internet. Firewalls control the flow of traffic between the private networks and the un-trusted / public networks. All the traffic from the public networks are controlled, authenticated, filtered, and logged according to the policies set.
In traditional wireless access points, generally the wireless connection is protected by the latest industrial security encryption Wi-Fi Protected Access (WPA/WPA2). Any traffic which is successfully authenticated will flow to the private networks no matter whether the traffic contains harmful packets or not. Business / corporate networks require strong security protection for all the traffic flow from both wired and wireless connections. Wireless traffic must also be controlled and treated in the same way as those wired traffic by such kind of firewall and even filtered by such kind of intrusion detection system. Therefore, business class wireless networks need special wireless access point devices which are specifically designed with strong security in mind. Consider SonicWALL SonicPoint-N.
What this Product Does
SonicWALL SonicPoint-N Access Point Devices are designed with business class features with strong security protection. SonicWALL SonicPoint-N Access Point devices are powered by the latest wireless industrial standard 802.11n with dual-band technology to support either 2.4 GHz or 5 GHz frequency bands, and are compatible with 802.11b/g legacy clients.
Combined with the multiple-input multiple-out (MIMO) technology that applies multiple antennas at both the transmitter and receiver, the SonicWALL SonicPoint enhances throughput and reliability. The APs support 40 MHz channel bonding and packet aggregation to support physical data rates of up to 300 Mbps.
Business Class Security Features
Like other wireless access point devices, SonicWALL SonicPoint-N supports industrial wireless security WPA/WPA2 and also WEP to support legacy clients. And to support your business class networks, the SonicWALL SonicPoint features wireless Intrusion Detection Services (WIDS), wireless firewalling and secure Layer 3 wireless roaming to allow all the wireless traffic to be controlled and filtered based on the security policy sets.
Not just that, SonicWALL SonicPoint-N integrates Wireless Guest Services (WGS) to allow you create security boundary to enforce password access for customers and other third-party guests. With this WGS feature, you can provide wireless guest Internet access through the auto-generation of guest accounts without compromising the integrity of your private network. And with the VAP (Virtual Access Point) features, you can enable up to 8 SSIDs to provide logical segmentation of secure wireless network traffic and secure customer access while sharing the same physical infrastructure. Users can roam from one SonicPoint to another SonicPoint while maintaining secure access to your complete wireless networks.
Flexible Deployment
Deployment is very flexible; you can deploy easily even without the availability of the power outlet because the device supports the 802.3af Power over Ethernet (PoE). Options include 3 removable external antennas with optional TNC connectors to support other 802.11 wireless antennas; wall or ceiling mounting.
If you have already deployed any types of SonicWALL security appliances such as TZ Series, NSA or E-Class NSA series, you can centrally administer the SonicWALL SonicPoint with them without pre-configuration. And the good thing is that the system can detect and identify any rogue access points on either the 2.4 or 5 GHz frequency bands.

The Best For Your System
If your computer comes with elementary memory, then definitely you need a memory upgrade. There are different types of computer memories; and every memory has its own distinct functioning. In general, a computer memory has four prominent characteristics namely, volatility, mutability, accessibility, and address-ability respectively. The performance of a memory is therefore based on these virtual characteristics.
The volatile or temperamental memory is the emotional computer memory, which functions in a similar manner human emotions work. As humans have vacillating emotions and so does the computer’s volatile memory. Volatile needs constant power supply. If there’s no power, then there’s no volatile.
The dynamic and static computer memories are part of random access memory or the RAM. Both are volatile in nature, and need constant power source altogether. Dynamic memory refreshes itself after regular intervals of time, whereas the static memory doesn’t refresh itself. The mutability characteristic of a computer memory is meant for reading and writing storage files, and come as immutable and mutable types respectively. It is extensively used for both secondary and primary storage purposes. ROM is a classic example of mutable and immutable storage memory which is quite crucial in writing on CDs, DVDs etc.
Sequential computer memory works great for off line storage purposes, as it is slow and all the information is gathered and accessed in a sequential order. Accessible is quite common in RAM as well as sequential memory, and gives an access to the stored files, which seemingly appears as instantaneous.
Lastly, the address-ability characteristic of memory is in three forms namely location, file, and content. For fast computer operations it is very necessary that you go for regular memory upgrade. If you are not upgrading the memory from time to time, then you are losing heavily on your computer efficiency. Memory can be purchased from third party vendors, but make it sure that you get original memory and along with the warranties, or else, in case of any technical fault, you’d be at the problem end.

Hub Troubleshooting
There are various parts of a network that can go wrong. You have to make sure that every part of the network functions correctly including the network adapters, cables, connectors, switches, hubs, routers, etc. Network hardware isn't the only thing that needs to be setup correctly; there may be software issues as well.
Here we'll talk just about some hardware aspects of a hub. A hub and a switch have practically the same function. Switches have replaced hubs, so if finding good troubleshooting for a hub is hard, try doing a search for an Ethernet switch- the information can easily be applied to a hub.
The speed of your network will only operate as fast as your slowest component if you have a 10/100 Megabit per second hub. If you have an old computer with a 10 Megabit per second (Mbps) network adapter consider upgrading to a 100 Mbps network adapter.
The length of cable also plays a role in the speed of the network. The maximum length for a RJ-45 cable for a 10 or 100 Mbps network is 328 feet. The length of cable between two 10/100 Mbps routers needs to be 15 feet or shorter.
Check how your cables are positioned if you have long cables. Make sure your network cable isn't coiled or bound together. This can create electromagnetic fields that will disrupt data transfer between the two Ethernet ports.
It's important to route your Ethernet cables properly. Try to avoid placing cables near lights, power outlets, and power supplies. These may create strong electromagnetic interference between the two Ethernet ports as well.
Make sure the connections at the Ethernet ports line up. Pins 1, 2, 3, and 6 need to line up exactly or you may have connectivity issues. Use a CAT5 cable to get the best results.
You cannot connect more than two 10/100 Mbps hubs together. To connect the hubs together make sure you use the uplink connector. If there is no uplink port then you need to use a crossed over network cable.
Canon PIXMA MP540 Review
Canon, like the majority of of its competitors, have managed to produce a number of all-in-one printers based on a similar print engine and to differentiate the models depending on feature set. The PIXMA MP540 works by using a similar 5-ink print system as with the £100 MP620, however, this machine is priced at 25% less, thus something has to go.
Looking a bit like past Canon all-in-ones, having gloss black piping along with highlights reminiscent of an oriental lacquer box, this particular machine appears clean and well proportioned, when closed.
The A4 scanner can be seen once you lift up the silver and black cover and to the right of this is a flip-up cover with a 48mm LCD screen placed into its underside that reveals a normal Canon user interface, which include a click wheel for menu selection. A flip-up cover under the control panel reveals 3 memory card slots, that can handle all the normal kinds, and underneath it is a PictBridge socket.
On the rear you can find sockets for just the main cable and USB. There is no Ethernet or perhaps Wi-Fi option on this particular machine along with other features missing in comparison with other models further up the range include things such as CD/DVD print, an Automatic Document Feeder and duplexing.
Canon does not make complete unrealistic claims about the speed of the PIXMA MP540, declaring 7.3ppm for the black print and 5.5ppm for the coloured ones. With that, they remain to be somewhat behind from the day-to-day speeds you could expect, especially if your print runs are usually short. It is mainly because of the amount of fidgeting around the printer does before beginning to print.
We have measured a speed of 3.95ppm for our five-page black text document which rose to 6.09ppm for the twenty-page one. And the black text as well as the colour graphics job, five pages again, delivered a speed of 2.94ppm, therefore just the longer text document got near to the claimed speed.
Photo prints are particularly more quicker, with a 15 x 10cm print getting 1:48 in Best mode and 1:03 on Standard mode. Just if you really need high quality reproduction do you have to switch to anything other than Standard mode.
The level of quality of prints from this machine is pretty good overall. The black text were clear, however it is not up to laser quality, the coloured graphics were bright and striking, with excellent combination of black text over the top. Even a colour photocopy results in workable colours and clean text, although there is a few minor blurring of black text over the colour.
Our test photos on the Canon's prime quality Platinum photo paper is exceptional, having beautifully smooth colour variations, lots of detail in areas of shadow and natural colours all the way through. Even on the a bit cheaper Pro paper, the photo images are natural and have a good range of detail. These photos are the best we have seen so far out of any machine under £100
How to Install and Connect a Printer
If you have a computer it is more than likely that you will need to connect a printer to enable you to print out documents etc. When you purchase your printer you will need to install it properly with the least amount of fuss. With the printer will come a printer driver which is the software needed to connect it to your computer.
Here is how you can install a printer:
Switch on your computer and consider the following options that are appropriate to your situation:
• If the printer has a plug and play facility then the Windows application will identify and automate the installation for you. All you have to do is set up the printer and connect it to your computer with the appropriate cables. Switch it on and you are ready to print.
• Printer with disc: Insert the driver software into the CD drive and carry out the on screen directions. Once you have completed all the instructions you should be ready to print
If the printer has neither of the above options then you can do it manually yourself. Proceed by clicking Start - Control Panel then Printer. This will take you to the printer section. Here click the Add A Printer button and the Printer wizard will start up. Then, follow the instructions. Choose the Add a Local Printer and hit the next button.
The Wizard will then ask you to specify which computer slot that you want your printer to be plugged into. Click your cursor on the arrow on the Using an Existing Port Field and choose the required port. If you are not sure which ports to choose then go with the port that Windows suggests. Once selected hit the next button.
The next instruction will ask you to choose the manufacturer of the printer you are installing and the model. Choose which is appropriate to you.
The next instruction is to give your printer a name. You can include your own or just leave the default name which is the printer's manufacturers name and printer model.
You can use this as your default printer. If you wish to change the default to another printer then deselect the Set as the default printer tick box that is under the printer name edit box.
Remember you are not limited to installing one printer as you can install as many as you want. Just remember to set the default printer as the printer you use most often.
Buying Cheap Used Laptops
Frankly it is not advisable to buy cheap used laptops but who's to say one can't?
If you find yourself needing to have a portable data processor with limited budget, it would help to know that with just around $500, you can get a brand new unit with installed windows 7, large hard drive, DVD player/recorder, built in USB, etc.
What are the chances of getting a good, low-priced deal?
Here's a basic pricing scheme:
For $500, you can get a brand new unit with factory and retailer rebates with the latest CPU, a 250 GB to 500 GB hard drive, USB 2.0, built in wireless 802.11G or N, a DVD/CD player/burner and a new warranty. A good place to comparison shop major brands is Amazon.
For $399-$499, you can get cheap second-hand laptops not less than a year old with featured specifications even better than newer models like a light business model with licensed Microsoft Office version. This isn't such a bad deal.
For $299-$399, you can shop for NetBooks instead of getting the lowest priced new Compaq. With this price range, don't settle for slow CPUs or RAM below 1 GB with a 100 GB+ hard drive and XP professional. You can opt for a model with installed Microsoft Office manufactured not more than 2 years ago so that the battery life is still strong.
$199-$299 can get you a reconditioned, older unit that is as good as the ones listed above and includes all the software.
For $99-$199, ask to test some cheap used laptops for a half hour and see if you find one you can use for the purpose you are buying it without any problems. If the store won't allow you, save your money another week and just buy a brand new unit.
Lexmark C910 Toner
Colored laser printers are more complex printing machines compared to their monochrome counterpart because a color unit employs 4 color toner cartridges (black, cyan, magenta, and yellow) to produce laser quality, color prints. Consequently complementing the intricate system at work in a color laser printer is the hefty pricing of its consumables; particularly that of the toner cartridge. In the past, laser printer users had no choice but to carry the burden of expensive printing costs. Nowadays, users have the option to recycle empty cartridges and refill its toner hopper with a fresh load of compatible toner supplied with toner refill kits.
Toner Refill Kit Scenario
While colored laser printers such as the Lexmark C910 would require individual refilling for its 4 toner cartridges; it is a rare occurrence for all cartridge units to simultaneously dry up of respective toner supply. In most instances, the black toner cartridge goes empty first. When that happens, users intending to recycle the empty cartridge need to purchase a Lexmark C910 compatible toner. The black C910 cartridge comes with the part number Lexmark 12N0771. The part number is necessary when shopping for toner that is compatible with a particular cartridge. Toner refill kits compatible with the Lexmark 12N0771 cartridge are retailed for around $60 while its OEM counterpart is sold at $215 a piece. Both consumables have been noted to deliver similar quality color prints and likewise rated for the same yield of 15,000 pages at 5% coverage.
The Refill Process
Toner refill kits come packaged with a bottle of toner powder, 1 funnel cap, toner wipes, latex-free gloves and an illustrated instructional material. In order to successfully refill the empty 12N0771 cartridge, users must follow these simple steps and refer to the diagrams and pictures provided on the instruction material.
- Unload the empty cartridge from the printer.
- Loosen the small screws holding the end cap.
- Gently remove the end cap to access the fill plug.
- Pop out the large fill plug using a flathead screwdriver.
- Properly discard old toner and wipe off residue.
- Pull out toner bottle and funnel cap from the kit.
- Tap the bottle of toner to loosen particles and pull off the seal to open.
- Securely attach the funnel cap over the bottle's mouth to prevent toner spillage and insert it into the fill hole to transfer fresh toner powder to the toner hopper.
- When the bottle is empty and/or the cartridge is full, remove the funnel cap from the bottle and set aside.
- Seal the fill hole by twisting the plastic hopper plug until it is firmly seated.
- Put back the end cap and make sure it is in place.
- Shake the cartridge gently from side to side to even out supplied toner.
- Reload the cartridge back to the printer and run a test print.
Samsung CLP-310 Toner Review
You aren't getting extremely quick laser speeds with the Samsung CLP-310 printer, however, it does meet the buildup in providing budget friendly colour laser printing in a small form factor.
Samsung employs talented individuals who are very imaginative with CAD, pencils, rulers and the tensile strengths of plastic and metal materials to create a handful of very great looking electronic products, from tv sets to mobile phones and a whole lot more.
And then there's the CLP-310.
It is a colour laser printer that looks just like the previous mockups for anyone's colour laser printer may perhaps look like, just a bit smaller. This may appear like idle complaining, but then Samsung is the company that produced the extremely appealing ML-1630 Laser Printer. Most probably those design folks have moved on, and what we get is grey and ultimately dull.
This may appear like an odd feature to start with, yet Samsung lists the small size of the CLP-310 as a selling point, and who are we to quibble?
At 388 x 313 x 243mm it is undoubtedly on the smaller end for a colour laser, although the claim that it's small enough to be placed "comfortably on a corner of your home, office, desk or bookcase" is probably a touch optimistic. Unless of course if you have quite large bookshelves, presumably.
If there is a feature that most people look for on a laser printer, it's speed. I'm curious then, that Samsung only rates the CLP-310 at a somewhat slow 16ppm for the black prints and 4pmm for colour. It's really quite a lot more honest compared to the other vendors - particularly Inkjet vendors, which often rate the ppm count at around the rate the printer could spit out blank paper - however it is also not a vote of confidence in what exactly is intended to be among laser's major selling points.
The CLP-310 is connected through a USB 2. only - there is no network port built in, although a tab of plastic on the back points to the potential for this particular framework to accommodate one - and is a printer only. Those people who are after a multifunction device must look elsewhere.
