What is a raid setup on a computer system?Like anything else it depends who you talk to.Raid hard drive systems had their acronym explained as Redundant Array of Individual Drives and Redundant Array of Inexpensive Drives. The acronym for this is the shortened term RAID.Capacity, reliability and performance are all important for file servers or other computer systems when you are storing large or very important files.It is often said that It is not if you hard drive will fail. It is at what point in time your hard drive will fail.Of course if your hard drives fail even if you have backup the last bit of data which was being written onto the hard drive when the failure occurred will be lost.You can get much greater capacities, avoid losing data from disk failure, and do all this with the RAID (the acronym for the system).RAID can now be done with standard commercially available hard drives so the cost is now within your price range for all the benefits and peace of mind RAID will give you.RAID can be simply explained as putting the hard drives in parallel sequence.The host adapter (usually called the RAID system controller) sits between one higher stream (on the computer side) and several lower rate data streams (on the hard drive side). When the computer writes to the disks , the host adapter takes high stream data and breaks it into many synchronized streams , one for each of the disks in process called Striping . Upon reading the data the host adapter takes the data stream from each disk multiplexes the sets of data streams and coordinates sending the resulting combined set of data onto the computer.It is all a matter of redundancy which makes RAID such a good thing in most cases.There are six different levels of RAID functionality depending on your requirements. the level of data security and integrity you want as well as the size of hard drive space you want.First of RAID Level 0 which spreads the data across multiple disks. You can get a similar effect to the RAID Level 0 by having multiple disks and using the features in Windows 2000 or its successor Windows XP.Since the data volume and rate to any specific disk is a fraction of the aggregate you will receive larger capacity and better performance from a RAID 0 setup than from any one conventional disk.As well data can be sourced from multiple drives as once. This can be most useful in shared situations which may benefit from enhancements in speed, two examples which come to mind are game servers and peer to peer (P2P) file or music file sharing servers.However since there is no allocation for error correction or redundancy RAID 0 is not a safe system for vital data. Data will be lost on disk failure. Only use RAID 0 in situations where you need the extended disk capacity or performance gain but not enhanced data reliability.Secondly in sequence there is RAID Level 1.In the same way that RAID 0 focuses solely on storage capacity and performance with no concern whatsoever on reliable data storage RAID 1, which us also called Disk Mirroring uses disks in pairs to save the files in a redundant manner.Several points.One performance may be slower as it takes time for the host adapter to send the data and for the drives to write it to disk,Secondly a user may delete or damage files which of course will be stored in that way on both drives.Raid 1 hence offers better reliability than RAID 0 or the conventional drive setups but does not give full security for your data or enhanced performance.Next in sequence we have RAID Levels 2, 3 and 4.Raid 2 adds one or more disks to hold error correction codes with which lost data can be reconstructed.Raid Level 3 is the same as RAID Level 2 but uses a simpler code the maximum storage capacity with Raid 3 may be somewhat less.Raid Level 4 is nearly the same as RAID LEVEL 3 but instead of Striping across disks is operates at a sector level, You now have the better situation of both a simpler , less intensive demanding system and as well as good data reliability . In addition performance may be enhanced as large data blocks can be written faster due to more coordinated writing to the drives in smaller sector areas.Lastly is RAID Level 5.Raid level 5 is the same as the excellent RAID Level 4 except that instead of dedicating a single disk to storing the data the data stream is striped across all the disks. You have greater performance with greater reliability for your computer systems.A RAID setup may take some effort and training on your part.Base your planning for your new RAID system on a careful analysis of your needs.What is important in your situation currently? Disk size capacities, data reliability and integrity, performance or a combination or all.
Processors The core of your system how to choose the one thats best for youThere are a few things that you need to consider when looking at processors and when thinking about what processor would be best for your system. The things you need to look at are socket type. If you dont know what socket types are, they are the pins located on the bottom of the processor, the number and pattern are what determines the type. Bus speed, or front side bus, this is the rate at which information moves from the processor to the motherboard, this will affect the overall speed of your computer. Other things to be considered are how to purchase your processor and if its compatible with your motherboard or the motherboard you are looking at purchasing.Socket types and motherboards go hand in hand. The socket type has a hand in determining the motherboard and what socket types a motherboard can accept obviously has a say in what type of processor you can look at. Each processor you look at is going to tell you the speeds at which it can process data this is the bus speed. This is an important factor when choosing your processor. The faster the speed the more you can do with the processor because the more the processor can handle. Something that also needs to be considered the faster the processor the hotter it will get. Some of the higher end processors come with their own fans and are a good investment if you plan on using your computer heavily. Once youve determined the bus speed, the socket type, and if the processor youre looking at is compatible with your computer its time to check out where to buy it. There are several options you can purchase it OEM or retail. Heres a run down of the difference, OEM this is usually what happens when you purchase it without a box and no heatsink and fan. Retail is you simply purchase just the processor itself in a retail box with the manufacturers heatsink and fan. There can be some real savings either way depending on what you need and what youre looking for. Another word on motherboard compatibility, older motherboards may not be able to handle the latest processor technology and visa versa making sure your processor is one that is going to work well with your motherboard is one of the most important factors that need to be addressed while deciding on your processor.There are two main producers AMD and Intel each have their good points. Most people will have heard more of Intel, or have heard of the Pentium. AMD came into the market late but rivals Intel in quality for value. Intel does still have some edge as they produce the chipsets, which allows them to adapt faster to new technologies. However the AMD 64 and Pentium D are about equal so the choice of who to go with is up to you and your personal preferences and needs.Now that you have the basics on choosing your next or first motherboard, you might want to check out some of these top manufacturers AMD or INTEL.
I dont know what other nationals have against us as Americans.I was talking to another national when I visited Europe some months back. Do you know what she said?She said we Americans are a very fastidious lot. She was specific and said we have embraced Satellite television with open arms when it was introduced because of the unprecedented programming options it offers.But does that make us fastidious? I dont know, but we do have a lot to be thankful for when it comes to Satellite TV. But what do we Americans really think about Satellite TV?Talking about Satellite TV- after a decade what do we have? The same set of people who swore Cable TV is the one and only TV option have switched allegiance without battling an eyelid when satellite TV with all its awesome offers made its grand entry.This was in spite of the fact that satellite TV was an expensive service back then (but now cheaper than Cable TV), and it was also pretty difficult to navigate. The operators of the service caught on to this fact quickly and went to work with the sole aim of gaining the confidence of customers.They came out within a short time with a product that was simply irresistible; small satellite dishes that can be easily mounted on almost any surface and which have the ability to provide unlimited programming channels to subscribers.This masterstroke catapulted satellite TV to the top of the market with an annual growth rate of about 30%, and leaving cable television a distant second at only 10%.What was responsible for the huge leap was the great price review the service also underwent as it became more affordable to a wide spectrum of the society coupled with its now improved programming which is now in digital format.The last point above is obviously the major reason behind the high quality picture and audio of satellite TV.Due to the rather strangle hold the cable television companies have over the localities they operate in they became sloppy in the area of customer service.Satellite TV providers on the other hand have a wider area of operation hence deal with a wider population who if not treated with courtesy will simply walk off to the nearest competitor. This is why they offer flawless customer service which has also helped bring in more subscribers.
Step One: Be Proactive!You won't land any video game tester jobs if you just sit around and wait for a "Game Testers Wanted" ad to appear in the paper. It won't happen. So instead of sitting back and waiting for a miracle to occur, just get out there and find the perfect video game testing job for you.Head straight to the game companies and developers and apply for testing jobs. Since they aren't looking for you, the only logical step is to actively search for them. Once you find them (which shouldn't take too long), apply for a game tester position with them and then repeat the process for as many different companies as humanly possible.On your application/resume, brag about all of your video game achievements, such as the consoles you own, the games you've played, the games you own, the MMORPGs you are apart of, and anything else that shows how much experience you have with video games. And if you want to help your cause even further, create a website/blog that talks about video games, gives reviews, previews, cheats, hints, tips, etc.You have to remember that experience and professionalism count for a lot in this industry. Therefore, the more experience you have and the more professional you are, the better your chances are for getting a "video game tester" job.Step Two: Step Out of Fairy Tale Land and Into RealityYou have to realize that video game testing is a job. Yes, it's a really fun job, but it is still a job nonetheless. This means that you have to treat it as such and take every part of it seriously. Don't merely sit down and play the game to have a good time. Sit down and play the game so that you can collect a paycheck when you're through.Many "wanna-be" testers believe that being a professional video game tester is a "no work, all play" type of career. Honestly, they couldn't be more wrong. Although there aren't huge amounts of work that a game tester must wade through, there are still a few things that he/she has to complete. For instance, filling out reports. Surprised? Well, most aspiring young testers are when they hear that there is actual work involved with video game testing.Contrary to what you may have thought, you won't be simply playing games and giving your opinion on whether they are good or not. You will actually be testing them. You will play through a game, find any bugs or glitches, and then fill out reports on any problems that you come across. This is to help the developers and programmers locate and fix those problems. You don't have to be an English professor or a college graduate to write bug reports, but you will have to have basic writing skills. Aside from the reports, you will also be required to fill out numerous questionnaires; which are typically opinion based.As soon as you accept the fact that you'll be doing actual work as a video game tester, you will have much more success finding testing jobs.
The US is home to a large and growing number of dental implant companies, whose implant manufacturing processes are performed in accordance with strict Food and Drug Administration policies. FDA monitors the manufacture of dental implants as closely as it does that of medical implants, with strict attention to sanitation and quality control.What Dental Implant Companies DoDental implant companies produce all the components used in dental implant surgery; a dental implant is either screwed directly into a patients jawbone, or built as a custom-fitted plate to be instated between the jawbone and gum.The hardware of the dental implant is made of titanium, which is a metal highly compatible with the bodys own systems and almost never causes and adverse reaction in the surrounding tissues. Titanium has been used for nearly forty years in hip transplantation.The implants visible tooth structure is of ceramic. How their titanium hardware and ceramic teeth are built and pieced together is the only thing differentiating the products of different dental implant companies, and different dentists may have preferences for different brands of implants.Innovations From Dental Implant CompaniesDental implant companies are constantly looking for ways to improve their products and their market shares, and one of the recent innovations which many of them have adopted is the use of nanotechnology in their implant surface design. They claim that using nanotechnology will reduce healing time by as much as fifty percent and improve the integrity of the dental implant and bone bond.Dental implant companies which have adopted this technology include 3i, Bicon, Astra Tech, and Straumann. Straumanns SLActive implants, in particular, have been well received by US dentists, but a survey indicated that many dentists using the SLActive implants did not realize they incorporated nanotechnology. A majority of the dentists surveyed said that among dental implant companies using the technology, 3i was the name the recognized most readily.Another advance from the dental implant companies, and one which could have very far-reaching effects on the entire industry, is the introduction of the Immediate Load Implant from Sargon dental Implants. The Immediate Load Implant is inserted and expanded to fill the bone opening immediately, giving the implant much greater stability than is normal at the initial stage of the implant procedure. The FDA has approved the Immediate Load Implant, which has been praised for causing very little bleeding or swelling.Dental implant companies are always looking for the next big advance which will make dental implants available at less cost and inconvenience to a larger number of people. And with ever increasing life spans meaning that more and more natural teeth will have to be replaced, the dental implant companies should be busy for years and years to come!There are more than 50 dental implant companies operating in the United States today. Of these, many have a web site, enabling dentists to research products and the public to research the procedures involved. Typing dental implant comapnies into a search engine will provide a huge amount of information about the companies and the products they make.
