A grid computer looks something like this, except the computers are spread in rooms around the world

There are a number of areas of investigation in which amounts of data to be analyzed is so extensive that it would be a decades shuffle through or combine them with conventional computers and scientific methods. A possible solution to this problem would be for the use of very expensive super-computer networks, which can rent out their work for different teams. But the best way, some scientists say, is that the average computer user in the lease at least part of their computers' processing power on a computer network, which consists of millions of ordinary machines, which at the same time.

The network can be used for a wide range of possible applications, ranging from modeling of the formation of the universe and galactic collisions to find a cure for dengue fever and the discovery of extraterrestrial life. By itself, each of these studies would absorb enormous amounts of work and the ridiculously high amount of computer resources. But by splitting the work between the many small users, this problem can be solved. In principle, experts say, more computers, the better. More processors can be used to either find work as quickly as possible, or analyze large amounts of information than first planned.

"The results will be shared by researchers who are interested in the development of drugs against the disease [such as dengue fever]. Actually, if you download the program from real volunteer company, then it is very safe. On the other hand, if the user has a hacker, they can to ensure that data which they work. But the chances are remote, for most often are shared, so that even a real hacker could obtain only a small amount of data. He could not cope with big picture, "Taipei-based Research Academia sinica expert Simon Lin told BBC World Service's Digital Planet.

He added that "costs [in relation to this type of research] are much lower. And secondly, we see the strategic importance of the Asian population in scientific cooperation. This is something they are less known. I think this is part of a very long-term displacement or transformation. Ultimately, science in the 21st century will be performed in a different way. This major change in the Internet and digital technology for us, but the scientific process has not really changed much and volunteer computing is one of the possible directions that can change the way we conduct scientific research. “

"Well, there is an altruistic imperative, you can actually feel good. You will contribute to scientific research and the search for UFOs or perhaps even something to cure cancer. Many of these systems now offer a points system where you may be able to submit experiments or things you want to research the system and then you built up enough points in the system, you just made yourself. This is an appeal to a large part of the time for academic researchers, but you can see in the future that there is a time when people have access to grid computing for personal projects, technology blog Tech Crunch Europe Editor Mike Butcher concluded.

How Flash Memory Works?

Flash memory are solid state electronic devices with random access memory capabilities, used for fast digital information on storage. They are used in a wide range of applications such as storage of BIOS living in a typical digital computers, as the winner of the capacity of hard drives for digital cameras and memory cards for laptop computers and video consoles.

The technology used to produce flash service is based on EEPROM (electrically programmable with erasable read-only memory) chips, which comprise the memory banks set up in storage boxes made in the network of columns and rows. A basic cell has two baggage MOS-transistors to each intersection, and are separated by one layer of oxide. The two transistors are known as floating gate and control gate.

When the floating gate is tied to the line of cellular stores edin'1 "bit logic. The value promeni'0" logic through a process known as the Fowler-Nordheim tunneling, which changes the distribution of electrons inside the floating gate. When the charge relates to floating gate of the column, it passes through the transistor, then sewage system land in which the formation of a negative charge is created by the other side of the oxide layer.

After Electric charge forms, no other electrons can penetrate the layer and on the other side due to electrostatic forces, thus establishing a distribution slightly higher fee of 50% between the floating gate and control gate, which records kato'1 "logic. However, when the fee allocation between the two transistors falls below 50%, then the cell is evaluated as baggage edin'0" bit logic.

To delete flash memory and return to electronic distribution inside it, a high-voltage charge is used to generate electric fields that study of all cells na'1 "logic. This can be done in certain blocks of memory or the whole chip. Flash services may retain the information only on condition that they have power, however, flash RAM can maintain the information stored without requiring any additional sources of energy.

There are several types of flash service, each with different characteristics in terms of size and storage capacity, but they all shares roughly the same properties. They are solid state devices, thus, which have no moving parts to keep them quiet, have quick access speeds and are relatively small in size. They consume low amounts of power while in use and can provide storage capacity ranging between a few kilobytes of several tens of gigabytes.

Eee PC now officially with Microsoft's Windows XP

Eee computers were running Windows XP already for some time by the ultra-mobile PC enthusiasts who are on the small device, which meet their needs. Asustek decided that it's time, the mystery of the relationship between the machine and the operating system from Microsoft official and presented his version of Windows XP.

The choice of the operating system allows the user to purchase a Windows XP-based computer, instead of the eye-candy, but mysterious Xandros Linux-based operating system. The part of "Easy to learn, work and play, the philosophy that the yard a series of Windows Live products, such as mail, messenger, photo gallery, and the" Family Safety "child safety more with the operating system.

Another message is the input level Microsoft Works suite, but only in certain regions, because the software is not limited to certain versions, the limits of localization.

The new operating system, gave rise to concerns Eee PC holders because of the wear and tear of the rumors about the leveling algorithms, which are suspected, increase the life of the disk finds included. While the vast majority of Linux-based operating systems (and some integrated version of Windows), which deals with the computer-solid state drive easily through the integrated functionality for wear leveling algorithms, the standard version of Windows XP will pay no attention to this aspect .

However, I must say that there is no danger of running Windows XP on Eee's solid-state drive. Eee flash drive has an estimated life of 1 to 5 million cycles letter before the outage-out should normally occur. In view of the fact that SSD device can be at a speed of 3 megabytes per second (as opposed to ordinary DBVARIANZ 'Write a speed of about 80 MB / s), would enter port listed After more than 84 years writing on the Even SSD.

The PC Eee not officially prices at the time of his writing, but it is claimed that the version of Windows XP comes to $ 30 to $ 60 premium, based on the submission of Linux. There is a question that remains unanswered: What is it for the version of Windows XP in the Eee July, the day on which Windows XP is gradually abandoned by Microsoft?
