Top 10 Supercomputers in the World

Supercomputers are defined to be the fastest line of computers. Contrary to mainframes and microcomputers, supercomputers are dedicated to execute only a few programs simultaneously. This is to avoid compromising the speed needed for tasks requiring a lot of processing speed. Among the functions of supercomputers are weather forecasting, high-end graphic animations, dynamic calculations, nuclear power researches, and fuel exploration.

The speed of supercomputers is measured in FLOPS (Floating Point Operations Per Second). Before, supercomputers are stuck to what is called “Petaflop Barrier” or A thousand teraflops. However, in June 2008, the “Petaflop Barrier” has been shredded by IBM’s Roadrunner installed at DOE’s Los Alamos National Laboratory (LANL). Today, there exists two supercomputers breaking the petaflop barrier.

Holding on to the No. 1 spot as the world fastest computer running in 1105.00 Teraflops is IBM’s Roadrunner found in Los Alamos National Laboratory, USA. Second place is the second teraflop barrier-breaker with a speed of 1059.00 Teraflops is Cray XT5 of Cray Research at Oak Ridge National Laboratory, USA. Third spot is running in 825.50 Teraflops called JUGENE of IBM located at Jülich Research Centre, Germany. Fourth place is Pleiades of SGI based in NASA/Ames Research Center, USA with a speed of 487.01 Teraflops. Fifth post is Blue Gene/L by IBM installed at Lawrence Livermore National Laboratory, USA running in 478.20 Teraflops. Sixth placer is called Kraken by Cray Research found in National Institute for Computational Sciences, USA with a speed of 463.30 Teraflops. Seventh place holder is IBM’s Intrepid running on 458.61 Teraflops at Argonne National Laboratory, USA. In eighth position is called Ranger by Sun Microsystems located in Texas Advanced Computing Center, USA with a speed of 433.20 Teraflops. IBM’s Dawn is in ninth place with its 415.70 Teraflops speed installed in Lawrence Livermore National Laboratory, USA. The top 10 supercomputer as of ISC09 conference on June 23, 2009 at Hamburg, Germany is called JUROPA by Groupe Bull located in Jülich Research Centre, Germany.

What’s the Right Desktop For You?

With so many desktop computers today, how do you know which is the right one for you? Choosing a desktop can be dizzying with the choices available. The different specs of each of these can give you a hard time deciding. With the advancement of computers today, a particular desktop might be outdated very quickly so you really need to determine the best features out of the options available.

What you need to do first is to decide what you need the computer for. It includes what you’re going to do with your desktop, whether you do games, watch movies, and so forth. To be safe, you should consider the desktops in mid-ranges when it comes to their specifications. You only need the powerful ones if you intend to use software that requires heavy specifications. You can perform a search first in the internet if you still don’t know what you want, there is a lot of information you can find there using the search engines we have. The common things you need to consider aside from the hardware and the specification of a certain desktop are the things like warranty, technical support, upgrades, and the quality of each component. A quality part such as the keyboard and mouse can make you comfortable even if you work for hours, so make sure you have those quality ones.

You also need to consider all the “extras”: examples are the DVD burner, more USB ports, and a webcam although they are not that necessary for your desktop, theycan still give easiness and enjoyment while you do your work. If you’re willing to pay extra amount then why not include them.

Before making a decision, list the entire brand you want for the components of your desktop and compare prices and quality with what’s available in the market. Do these and you will get the best value out of your budget, as well as a desktop just right for you which will give you comforts while working.

The Fastest Best-Selling Desktop Computer Processor Ever

This is really a jaw-dropping speed processor a computer can ever have. I am talking about the AMD’s Athlon X2 Dual-Core QL-64. It belongs to the AMD’s X2 multi-core processor family with an awesome CPU speed of 2.16 GHz. It is equipped with the 65nm AMD’s manufacturing technology but with a smaller wattage rate of 35 watts. It is definitely the fastest computer processor these days.

Athlon X2 Dual-Core QL-64 has two separate CPU cores on a single die. Each core is running on 2.16 GHz speed. The standard multiplier for determining the overall speed of a processor is 1.8. So when two cores are running together, Athlon X2 Dual-Core QL-64 can have an astounding speed of 1.8 X 2.16 = 3.88 GHz. You could barely feel any buffering or lagging even when you are running on different high-end multi-thread software applications all at the same time.

Athlon X2 Dual-Core QL-64 processor bus speed can also reach around 3600 MHz. Of course, the motherboard controls the bus speed so it must meet with the CPU’s bus speed for optimum performance. Bus speed is the rate at which computer processor can transfer or process information (with different computer parts like motherboard and RAM) per second. Typical bus speed for motherboard would be 4000 MHz and RAM capacity of 4 GB.

Athlon X2 Dual-Core QL-64 has a shared L2 cache memory of 1000 KB (1 BM). The CPU static L1 cache can store information at 128 KB. When this L1 cache is consumed upon computer operation, L2 cache can store up to 1000 KB of data for processing and file swapping. With Athlon X2 Dual-Core QL-64 wattage rate of 35 watts, it reduces the chance of having processor overheat. It also consumes power at a lesser rate almost half of common Intel multi-core processors.

How to Troubleshoot a Printer

A printer is a peripheral that converts a soft copy document into a hard copy document. This device is very much helpful for reports and the like since this would produce a tangible document that can be viewed even without a computer. But what is the use of a printer when it is not working? Here are some basic steps on how to troubleshoot a printer.

First, the printer should be plugged on to a power supply. Check the power ratings before plugging it into a power supply source. The power ratings are usually seen at the back or bottom of the printer. (Caution: Don’t plug the cord when the maximum power rating is less than the power supply source. Example: Plugging a 110V printer to a 220 power supply will damage the printer). After inserting the cord in the power supply source, check the power indicator if it lights. If not, press the on button. This should make the printer power up. If this does not help, contact the manufacturer regarding this issue.

If the printer does not print the document, first, check the printer if it is the default printer. This can be checked by going to the control panel and open printers and faxes (for XP). The default printer is the checked printer (sometimes labeled as the default printer). If the printer being used is not the default printer, right click the printer that is being used and select “set as default”. If the printer is not included in printers and faxes folder, the printer needs to be installed which is described on the printer’s manufacturing handout. Find the installation process and follow it step by step.

If all of these do not solve the issue, refer to the printer’s handbook for more tips on troubleshooting the printer.

Free Your Head from Headaches: Perform Computer Maintenance

Computer equipment maintenance is very necessary to have your computer equipment work efficiently, have it run smoothly. There are a several ways of doing computer maintenance but there are some other ways that are missed. Here is the complete checklist to make the computer maintenance at its fullest.

The things that should be kept in mind are tasks that include backing up, setting up firewalls, keeping computer healthy, resolving power issues, putting a stop to spying, and keeping away from trouble.

Backing Up: Any document that you create on an external drive should be kept safe with backups using other external drives such as USB. However, you should also provide backup for important data or any files saved in your computer hard disk. In case you have to reinstall, also keep backups on computer programs to avoid downloading these programs again and waste a lot of your time. The frequency of providing backups depends on how often you make changes to your documents. Software drivers and operating system disks should be kept in safe place that is moisture-free and easily accessed.

Setting Up Firewalls:

Firewalls are responsible in keeping your computer away from programs that would enable others to access your computer. Hence, it is termed as the “locked gate” for computer hard drive. This can be set up with the use of internet security software such as Norton and others.

Keeping Your Computer Healthy: The best way of keeping your computer healthy is to install a good antivirus software. Often, aside from firewall, this also comes with when availing Internet Security software. The antivirus program scans the files stored in your hard disk and even other external disks and email to detect if they are infected with viruses or worms. This way, you can decide whether to open the file or email message or not because it will give you an alert message and sound. Of course, only nuts would open a virus-infected files or email messages. Update your computer regularly by activating the virus scanning. You can actually set the scanning automatically by setting Automatic Updates.

Power Issues: Electrical surges can damage your computer so it is always recommended to use an excellent power surge protector. In buying one, you should me cautious of surge protectors with MOV or metal oxide varistor because it damages any time. It might be cheap but you put your entire home in risk of fire.

Putting a Stop to Spying: Spyware programs are recommended to have installed in your computer to avoid other parties who are remotely monitoring your computer secretly. Spywares can be downloaded from different online sources; however, choose only the ones that are recommended by computer experts. If you don’t know one, you may try asking the good guys in computer equipment rental shops in your area.

Keeping Away from Trouble: You should also be cautious enough when downloading any data forms. Some have viruses, spywares and Trojan worms in them. Downloadable files from unconfirmed sources are potentially damaging so better keep away from them.

Computer Maintenance can be Fun

We usually think of computer equipment maintenance as another burden or an addition to our household chores. Like any other household chores, computer maintenance is also a requirement to keep it running smoothly and prevent computer problems that may arise any time. However, this kind of mentally can be changed if you know enough about how computer works.

The computer equipment maintenance can be done in a lot more different ways. You can have automatic updates, website updates, and with the use of utilities.

Automatic Updates: I don’t know if computer owners find it fun seeing their computer updating on its own. But generally, the task of setting up the computer updates such as anything that comprises the operating systems (like Microsoft Windows, Internet Security like firewall and antivirus software) is fun to watch. Your mind would think how fabulously technology works. It is a threat not to update the versions of your internet security software and antivirus. If your computer is often used for downloading data and many types of files, it is advisable to have it updated as often as possible.

Windows Update can be done periodically with Internet Explorer browser. It automatically detects latest versions of the currently installed components of Windows.

With Windows XP Home Edition, you can also automate the critical updates by setting it up in the Control Panel. Just go to System then click Automatic Updates so that you can modify the frequency and time of updating.

You will be directed to a page containing the instructions on how to set up the automation of the updating of software versions.

Using Utilities: It is crucially important to have your computer be updated of its components. This is to keep the bad guys away and those who use it. Some internet security software is composed of important tools such as firewall, antivirus, porn-blocker, spyware detector, pop-up blocker, and spam filter. This kind of utility is a great help to keep your computer free from computer viruses, spyware and other things that are potentially computer destroyer.

Of all kinds of computer maintenance performed for computer, defragmenting is not really necessary. The recent review from PC World (a computer magazine) declared that defragmenting does not improve computer performance anymore. Defragmenting is done to gather up the pieces of files and places them together in one adjacent location of the computer hard drive.

Reasons Why Renting is Good

Buying is always the best way of owning something. However, if you don’t have enough financial resources to buy relatively expensive item such as computer equipment or laptop, renting would best suit for you. Having a computer this way offers great benefits in which some of these benefits are unrealized.

There are several options to avail a computer equipment rental service. Such growing number of online PC rentals provides an opportunity for you as a client to have as many choices as you wish. This way, you have the freedom and control which among the online computer shops you would choose. Of course, you would choose a company that would serve you best for a worth-it price.

Computer equipment rental shops are getting popular not because they offer rental service or they sell computer equipment and peripherals. They are becoming popular because of other services that they offer. They also offer rental service on other items that are of in demand use such as household items like furniture, clothes washer and many others.

Recently, stores offer incentives to people who avail their electronic or computer equipment rental service. The more often you avail the service, the more credits you can have. Your credibility as a rental client is established well especially if you have good record in renting any item from a particular store.

You can choose from monthly, weekly or every other week or month as payment schedules to make sure that even paying to the rental service that you avail won’t be a burden to you. Most of the online PC rentals that are able to establish credibility in this particular market industry offer money back guarantees and complete customer satisfying services. However, you should take note of how long does the offer would last in a specific rental option.

Other good thing that computer equipment rental shops offers is that they let you try the service for a particular period of time before having you decide to avail the service. Even on computer sales, they also allow the potential clients to try using the item you would be buying. This way, you can have the privilege to check if the item you would likely buy has all the necessary features you need or if it has defects which can either be minor or major.

Because it is handy, a lot of people find their work done more efficiently with a laptop. Most the jobs depend on laptops now. Business presentations are done wherever with a laptop. Unlike desktop computers, laptops are easy to bring wherever its user would go. However, laptops are more expensive than desktop computers.

To respond to that issue, there came a lot of online companies that offers rental of wide range of laptops. Renting is the best way of saving even if others find it impractical. But for desperate ones who got no computer available to use for the upcoming business presentation, going to notebook rental equipment shop is the best option to save and getting things done immediately.

Top 5 Qualities of a Good Computer Rental Hub

Since computer rental industry is also getting bigger, the number of online computer rental shops is also increasing. This event makes the searching of good shops to rent computer equipment is made difficult. If you are someone who ventures in computer rental or audio visual rental service providing, then you must know the top 5 qualities of a good computer rental hub in order to stand out from your competitors in the industry.

There are several computer rental shops but only few offers the services that customers are looking for. Quality service and complete inventory of stuff for sale and for renting are not enough; your establishment, the shop itself, should also have other features in order to attract more clients and make them return to re-avail the online computer rental services you offer.

Here are the top five qualities of a good computer shop:

(a) Fast computers: Clients nowadays are expecting too much especially on technology products like computers and audio visual stuff. Giving your client with computers that belong to decade old versions would certainly disappoint them. Of course, you will be receiving bad testimonials about your service. Fast computers are those that are of new models. New models of computers do not necessarily mean to be the latest release models; at least it should be a bit new. Computers this type runs and process tasks fast because of higher speed computer processor. In order to achieve higher computer speed, your computer RAM (Random Access Memory) must be higher.

(b) Fast access: Your computer equipment rental shop should also have fast internet connection. Most of your clients would and avail your service because of having this service feature. Checking your internet service provider for faster connection is needed. Of course, if you find that your ISP is not performing well, then it is better to look for another one—the one that can give faster connection speed that people need.

(c) WiFi: WiFi connection is almost omnipresent among publicly exposed establishments such as coffee shops, bookshops, hotels and restaurants. Adding WiFi features of your computer rental shop is a great advantage because it would mean additional income.

(d) Coffee and Food: Services like offering coffee and food to the clients is not just good for your income but also good for your clients. It is because, this service feature is one of the most in demand. It helps the client to feel relaxed. Of course, anyone likes a place where they can have their stomach get satiated with coffee and excellent food.

(e) Printing and Fax: Of course, your computer rental shop would not be complete without printers and faxes. Printing and faxing services, I would say, is essential to any business that offers computer equipment rentals. Most of the people who avail services like audio visual rental or online computer equipment rental services are office workers if not students who are always doing paper requirements. Taking advantage of this market would have you lead in the competition of getting the highest number of online computer rental clients.

Recycling Computer Equipment

The evolution of technology has banes and boons. Life became easier since the time when technology was invented. Its rapid development has even further enhanced the way of life in general. Doing more in less time and doing big or heavy things easily are achieved with the help of technology products. Comes with this is the harm that it gives to the environment and to the people in general.

Since technology is evolving fast, the things that it produces also quickly becoming obsolete. The need to replace them with newer versions that better serve the users’ needs is inevitable. If the obsolete models are replaced, what would happen to them? Are they just destined to the garbage pit under the earth? Unfortunately, the answer is YES, they are.

Computer equipments are highly toxic to the environment. According to the research that 75% of obsolete computer equipment products are being thrown into the garbage pit, and stored like a time bomb waiting to blow off the earth.

Computer parts such as cathode ray tubes, circuit boards and other related materials contain chromium, mercury, and lead. These elements are highly dangerous. If they are thrown in traditional ways such as dumping them in a garbage can to be thrown later in a dumping site or under few feet below the ground, they would be absorbed by the soil and underground water. Hence, majority of the community are relying merely on underground water, great health risk will be coming at hand. The landfill, where the technology product wastes are dumped, is the most hazardous place. The incineration of wastes would bring toxic elements into the air. Air and water pollution can kill not only the trees, water, air, land and all sorts of environmental components, but such pollutions can also kill the inhabitants of the earth, the humans.

That is the reason why we should not throw our electronic wastes. We can actually make money out of them. So, it is better to keep them; perhaps, you can utilize some of the computer parts for other technology equipment products. The good news is that there are organizations that buy electronic waste. The electronic wastes are recycled by these organizations for helpful purposes.

Recycling is the answer to prevent air, water and soil pollution. It helps the environment and the quality of life of human beings. This is the primary reasons why the recycling of obsolete computer equipment products is considered as great earth-saver.
