Samsung enters the field of flat computers with the Galaxy Tab, a device that tries to compete with the iPad ftom Apple.
Galaxy Tab was presented at the IFA exhibition in Berlin. The device uses Google's Android and initially will be available a model 7-inch screen and memory 16 or 32 GB that can be extended with the use of a memory card. The Tab supports connection via Bluetooth, wi-fi and mobile networks, has embedded chip GPS and gyro mechanism that automatically adjusts the display depending on how you hold the device. Samsung has not announced prices for equipment weighing 380 grams, and promises to enrich the series in 2011.Ακρόαση

The quad-core desktop PC with an operating frequency above 3.0GHz considered for some time high-performance products, but the processor has just announced that IBM is giving new meaning to the word "speed." The innovative company has the technical specifications of the z196, with new quad-core processor (default) frequency of operation is set at unrealistic levels of 5.2GHz.
Thus, the z196 is automatically designated as the fastest processor in the world, taking the crown from the IBM Power6 4.7GHz. The z196 has no more, no less, 1.4 billion transistors, or about 300 million more than the exapyrinous processors from Intel. All this in an area of 512 square millimeters, made using the technology of 45 nanometers.
Each core has 1.5MB L2 cache and the shared L3 eDRAM cache has a capacity of 24MB. It is not, so the possibilities of the new processor that IBM has decided to add and L4 cache, which connects different processors in a multi-chip module (MCM). We are talking about a common L4 cache capacity 192MB, through liaison with speed 40GB per second.
Of course, this processor is not addressed in the mainstream market and will contribute the exclusive mainframes to IBM. The price has not been announced yet, but I will move the region of hundreds of thousands of euros less per item.
The technical director of PandaLabs, Luis Corrons, announced the findings of research on the spread of malware circulating at the moment. According to the survey, approximately 25% of threats at this time to action are designed so as to be transmitted by devices connected to a USB port. One of the most familiar worms that are transmitted via USB is Stuxnet. Until a few weeks ago, this worm-and-operated not only undisturbed, and operated a fundamental defect in the Windows management system shortcuts (shortcuts). Basically, the worm infects a computer simply when the unsuspecting user opens a file manager and just sees the contents of the file. The Stuxnet automatically copies itself to the hard disk, without requiring the execution of a file.
Of course, transmission of malware via USB is not a new phenomenon. The virus Conficker used routinely to USB sticks to broadcast throughout the course of 2008. A fully updated antivirus and a lot of attention from the user's side are the best defenses against the threats. These two and timely action by Microsoft every time you discovered a security hole in Windows ...
