With the availability of the Release Candidate for Windows 7, Microsoft has also made public the system requirements for the operating system. The good news? Users who have already moved to a Windows Vista-tailored machine will not need to upgrade their hardware yet again just to accommodate Windows 7. In fact, the system requirements for the next iteration of Windows are roughly the same as for its precursor, with Beta testers indicating that Windows 7 outperforms Windows Vista on the same hardware.
Without further ado, the System Requirements for Windows 7 are “1GHz or faster 32-bit (x86) or 64-bit (x64) processor; 1 GB of RAM (32-bit)/2 GB of RAM (64-bit); 16 GB of available disk space (32-bit)/20 GB (64-bit); DirectX 9 graphics device with Windows Display Driver Model 1.0 or higher driver,” according to Microsoft.
The Redmond company emphasizes that the system requirements presented above represent the bare minimum required to run Windows 7. More »
What, exactly, are supercomputers? The clue is in the name, really: they’re powerful computers capable of calculating many millions of floating operations per second (FLOPS) essentially, they’re very, very fast.
While any array of powerful computers, such as a modern-day web server which consists of several motherboards (the main circuit board of a computer) running in parallel can be considered a supercomputer, generally the term is reserved for machines that dedicate their entire hardware to one complex task at any given time.
Take the NEC Earth Simulator in Japan, for example, which was created specifically for modelling weather problems associated with global warming. Or the world’s fastest computer, BlueGene/L at Lawrence Livermore National Laboratory in the US, which simulates the behaviour of biomolecular structures and protein folding. It’s capable of 600 trillion FLOPS (tera-FLOPS or TFLOPS), whereas, the six-year-old Earth Simulator is only capable of 36TFLOPS. BlueGene/L won’t hold the top spot for long, though. Supercomputers twice as powerful will be online soon. More »
For most users, Firefox doesn’t use an abnormally large amount of memory. For others, however, Firefox’s memory consumption is a major problem. Typical Firefox memory usage reported by Windows is around 50-100 MB, with virtual memory usage at 100-150 MB. These numbers will vary because Firefox is configured by default to use more memory on systems that have more memory available and less on systems with less.
1. System Extensions
WindowBlinds can dramatically increase memory use. To continue using WindowBlinds and Firefox without memory issues, add Firefox to WindowBlind’s exclusion list.
2. Download History
Firefox can slow down or hang if the download history is allowed to accumulate. Clear the download history (you may need to exit Firefox and delete the file “downloads.rdf” from the profile folder in some cases) and change this setting to solve the problem: More »
