Selecting The Right Computer

Wednesday, October 22nd, 2008

There’s no question that personal computers were built with baseline functionality- all of them can process documents, and to a certain extent, play multimedia and display the same. However, there are significant difference when we think of specific needs of users of personal computers.

Here is an easy to understand scenario: compare a student and a professional PC gamer. If you are thinking about which types of PC fits which, then you can expect significant differences between the two.

Here is a question to ask: what does a student need in a computer? Put yourself in the shoes of a university student, and think about what types of work and activities you will be engaged in. A PC is more likely to function as a typewriter or word processor for the average college coed. It is already a given that you will be printing and submitting a lot of papers and reports.

If you think about the degree or course of the student, such as engineering or architecture, then you can expect that there are certain changes from the basic type of PC. Definitely, the student has a huge database of files to be saved, and possibly even special software for designing. For sure, he needs ample disk space to accommodate all his files.

Now, if we are talking about space, then we are talking about hard disk space here- the lowest is 80, then there are those that reach 300 now. So that’s fixed- how about computing power? A student will not need a computer with extreme computing power or clocked speeds exceed 1.5 GHz- what would be the point? For video cards, it is the same- a regular video card with 512 MB will do. If the student plays some games, that baseline is also sufficient for playing. However, as for the gamer, it is another whole different thing.

A gamer would be using the personal computer in two ways- for work and for leisure. The leisure part would be the one that would tax the computer most, because it would be running algorithmic engines non-stop, playing multimedia and receiving input from the user at the same time.

In terms of the hard disk space, how much would a game fanatic need? For sure, 300 GB of disk space would not be enough, so a larger and more generous hard drive is needed. However, hard drives that can take more than 300 GB tend to be costly, so a way to get around this for gamers is to install more than one hard disk onto their PC. Think about it: installing one game may use up more than 5 GB of space alone, and a lot of virtual memory will also be needed as the game is being played.

When thinking about a processor that is powerful enough for the gamer, the basics simply would not do. Intel Skulltrail is one that is highly recommended for these purposes.

When is the best time to use my nitrous system?
When you see blue lights flashing behind you (joking), or you want to go fast, or do an unbelievable smoke show.Answer: The e-Ram is a distant cousin of the full blown turbo or supercharging system which employs a centrifugal impeller that must run all the time. They have to produce matched engine airflow, with high-pressure air compression (4 to 15 PSI is normal). This requires a tremendous amount of HP to drive the device.

What is a “silencer ring”?
A silencer ring is a metal baffle placed into the turbocharger inlet to reduce whistle from the turbocharger. It is installed in Ram truck engines at the request of Chrysler. The silencer ring has no effect on engine output, EGT, or boost levels. Removal: Remove the flex hose from the front of the turbo that goes to the breather.A silencer ring is a metal baffle placed into the turbocharger inlet to reduce whistle from the turbocharger.

How does a Magna Charger supercharger compare with a turbocharger?
All forced induction devices increase air pressure and density in the intake manifold by pumping more air than the engine would use without it. This concentrated charge of air results in a more powerful combustion stroke in the engine’s cylinders, resulting in improved performance over naturally aspirated vehicles. A supercharger is connected directly to the crankshaft by a belt; unlike a turbocharger, which is driven by exhaust gases.First of all, there are a couple different types of superchargers (positive displacement and centrifugal). The most popular these days seems to be the centrifugal supercharger which is basically the same design compressor as a turbocharger compressor. These compressors both increase in airflow and efficiency with impeller RPM’s. (Which basically means that doubling the impeller RPM doesn’t double the airflow, it increases the air flow exponentially.Every month I hold a Keyword Clinic teleseminar.

How to Create Your Server Backup

Monday, October 13th, 2008

Memory storage devices in your computer are great, but invariably, most of them have to face the problem of failure at least once. One day or the other, it is bound to happen, and when it does, it can leave you terribly stranded. You can prevent this by having server backup.

You have several methods for creating a server backup. The first is to load all your important files to a writable CD or DVD. All computer systems at present are equipped with CD/DVD writers and even if your computer doesn’t have one, you can buy one from a computer accessories store easily. It’s a very convenient option and having all of your important data safely stored elsewhere allows you to keep your mind worry-free about hard drive crashes.

An alternative approach involves using an external hard disk drive to create a server backup. It is similar to your computer hard disk drive, except you can plug it externally using USB ports or comparable slots. You can copy whatever you require on to the external disk. This way if your PC hard disk crashes, you will have all your data safely tucked in your external drive.

For businesses another good option is RAID, or redundant array of independent disks. RAID works by storing backups of all your data on multiple disks, giving you added multiple levels of safety. Even if one or more disks crash, there are others to safeguard your data.

Businesses have another choice, where an external services company stores all your data online for your convenience. Just like Google documents and Yahoo bookmarks are stored on the web; these companies host your data online via web servers. This is a relatively inexpensive service and an ideal backup server solution for mid-range and corporate businesses.

ETX: A Radical New Platform

Tuesday, September 23rd, 2008

Computer-On-Modules, or COMs, come standardized with the ETX, microETXexpress, and the ETXexpress systems. They offer standard functionality you can customize to any application needs. This provides for an inconceivable amount of flexibility, all the while allowing the user to keep its functionality. The total design of the ETX baseboard keeps related costs to a minimum. Indeed, products that have embedded ETX modules are very scalable and enjoy longer life cycles.

ETX solutions have enjoyed a wide variety of industrial applications, especially in the automotive industry. These complex software topologies have been integrated into such amenities as Adaptive Cruise Control and Lane Departure Warning systems. Meanwhile, engineering teams have been developing hardware that emphasizes the intersection of human need and computer precision.

With the advent of Computer-on-Modules, an old idea has been re-invigorated. Daughter boards, otherwise known as add-on modules, had one specific IO function. They would add exceptional connectivity or input/output requirements to an off-the-shelf processor board. Computer functions have now become more and more generalized, creating a need for highly integrated, small, less expensive, application-specific functions.

The synchronization of chipset advances with processor evolution, has presented a major challenge to most embedded systems. The result is better Computer-on-Modules which allow for an automatic upgrade path. The latest generation of interconnections enjoys the use of LVDS, or Low voltage Differential Signaling technologies, that make it possible to match the interfaces to any generic processing module. Computer-on-Modules currently utilize x86 models that possess a variety of standards and proprietary solutions.

There are currently applications that use embedded PDA with PXA255 X-Scales and WinCE 5.0 operating systems. These also use PXA255 and other diverse bus interfaces and mobile POS systems on ETX platforms. Certain industry CPU modules DMM-PC, X-board, ETX, and ETXexpress have successfully addressed the interface and speed to market problems. ETX is compatible with many baseboard designs and can be adapted for CPU architectures that are both comprehensive and customer driven. The use of interchangeable modules is scalable and offers many advantages over slower system integrators.

by Alan Wilson

Whether it will be for home use or business use, Lexmark ink cartridges can offer excellent quality printing. This is because it is designed to be compatible with Lexmark inkjet printers. There are several factors to consider in choosing the best inkjet cartridge for your inkjet printer. These include print quantity, expected print quality, print speed, features, paper type, and the printer to be used?that is, one should identify the need then choose the appropriate one among the different Lexmark inkjet cartridges available to suit that need.

Coming a long way since the early 90’s

Lexmark started as one of IBM?s groups in 1991. Later on, the company went public and detached itself from IBM in 1995. In the process, it had to do away with all the IBM logos printed on its products such as the laser, dot matrix, and inkjet printers. Lexmark became the first company to release a printer in the market that costs below 100 USD. It also made history by being the first to develop printing in 4800 x 1200 and 3600 x 1200 dpi resolutions. Moreover, in the world of photo printing, it pioneered in developing a stand-alone photo printer.

Lexmark was the first company to offer a printer for less than $100 and was also the first to come up with a printing of 4800×1200 and 3600×1200 dpi resolution. It also was the first to make a photo printer that could work on its own as a stand-alone model.

Genuine Lexmark ink cartridges deliver top performance for the customers varied printing needs. There are available inkjet cartridges that come at a cheaper price, often sold by less reliable suppliers under their own name or even a well-known brand name. Of course you will save money, but you could end up with a counterfeit ink cartridge with inferior quality that clogs and damages your printer head or the printer itself. Remember that bad ink can easily ruin your printer; you can easily end up paying more for your damaged printer. Original, high quality and compatible inkjet cartridges are the best choice.

To maintain the level of performance of your inkjet printer, you should always install a compatible inkjet cartridge. With the quality and reliability of Lexmark inkjet cartridges, as backed up by the company?s history and reputation, it is the choice if you are going for the best.

Registry Cleaners Help Save Your Time and Money

Thursday, July 10th, 2008
by Brian Emmens

You shouldn’t take your PC for granted. Time and money are both important commodities in life, and they’re invariably wasted when you neglect to take care of your PC properly.

You see, even the most hi-tech PCs are still suspect to problems if they’re not consistently scanned. And more importantly, all computers possess registries that, if not regularly checked, can cause the entire OS to deteriorate. If you want to avoid costly PC problems, you should really use registry cleaners.

Classic Examples of What Causes Computers to Break Down

Even the most careful PC user won’t be able to monitor all the files being used, stored, and managed by its computer. Without proper help, computers can easily be victimized by various forms of malware. These harmful programs can cause your computer to experience various problems like freeze-ups and inexplicable blue-screen displays. Such unwanted effects are usually caused by various factors including but aren’t limited to insufficient memory, stuffed hard drives, simultaneous use of multiple backgrounds, wear in internal parts, hardware conflicts, and last but not the least, a clogged Windows registry. Among all these, a clogged Windows registry may pose the strongest threat largely because PC users tend overlook them as a possible culprit.

How to Make Efficient Use of Time and Money with Registry Cleaners

A registry cleaner is capable of ensuring that your Windows registry constantly maintains a clean slate, one free from undesirable clutter like obsolete files. If you have a registry cleaner and you’re running it regularly, you’ll immediately notice a marked improvement in your PC’s performance. Your computer is able to run more smoothly, with no delays in starting up programs and applications. You no longer have any reason to visit a maintenance center and pay for expensive repair fees. With these, you get to save time and money.

Solving problems with your Windows Registry may not seem a crucial move at first glance but don’t let that fool you. If you allow your Windows Registry to continue in a state of disrepair, you might realize too late that it’s the biggest and costliest mistake you’ve made.

Bose Sound Dock Portable Review

Monday, July 7th, 2008
by Rob Reger

Ask nearly any iPod enthusiast and you’ll find that the Bose sound dock is the best speaker system you can buy. The only limitation is that the speakers aren’t portable with a large power supply and cord. The new Bose soundock portable solves this problem with all of the power and punchy sound of the original model. This is simply the best sounding speaker system available for your IPod and it’s portable. These speakers come with a high price tag; at $399 retail you’re not only paying for great sound but the Bose name at the same time.

The sound dock portable comes in two colors: glossy white and black. The speakers have a compact design that measures 12″ x 6″ x 5″ and weighs just over 5 pounds. The new portable soundock is very similar to the original model. One difference is the swiveling dock that rotates into the sound dock body for protection when traveling.

The portable soundock has the same simplistic design as the first sound dock. There are no physical controls aside from volume up and down. There is a small remote control included that operates the volume, playlists, playback control, and power on and off. This remote is small but has rubber buttons that make it easy to use and operate as long as you don’t misplace it. The remote works well enough and I was able to control my iPod from nearly any angle in the room.

The back of the sound dock portable has only two connectors. There is an analog input and a plug for the unit’s charger. It would be nice to have USB ports or video outputs on the speaker system. The sound dock portable is charged by a lithium-ion battery and holds a charge for about eight hours of normal use. If you crank the volume up you’ll get about three hours use which is pretty good considering the volume and amount of Bass the speakers produce.

The only flaw I can find in the speaker’s design is the sensitivity of the volume controls; however, the included remote functions well enough. The sound dock charges your iPod whenever plugged in; charging the iPod will deplete the soundock’s batteries at a much faster rate. The bass port on the back of the speakers also functions as carrying handle. Bose calls it the unit’s Wave Guide Exit.

The Bose soundock portable has an LED light behind the speaker grill that lights up when using the remote control and flashes when the battery is depleted. One problem with the portable unit is that if you leave it unplugged for fourteen days you can only turn your speakers on by plugging the charger in. There are no iPod dock inserts included with the speakers so you’ll have to use the one’s that came with your iPod; however, replacement inserts are available from the Apple store. The power cord has a built in cable winder that makes it easy to travel with; however the plug is large and takes up a lot of room. With a $399 retail price tag it is well worth your while to comparison shop online for sites with the lowest prices and free shipping. There is an optional carrying case but you’ll have to shell out $60 more for that.
