When you consider that computers now consume about 10 percent of the electricity generated in North America and that a great many PCs still end up in landfills, leaching deadly chemicals, it makes sense to adopt more eco-friendly computing options.
John Hiddema, technical consultant for Nerds on Site, is one of the many people making a conscious effort to go green. He recycles, buys organic produce, uses cleaning products less harmful to the environment, owns energy-efficient appliances, and has configured his
PC to use less energy. He’s also going green on the job. Some of the work he does for clients’ computer systems can be done remotely from his home office, drastically reducing his need for a car.
Here are some tips for making your technology use more eco-friendly.
1. Manage power consumption
Did you know that approximately 40 percent of the energy used for home electronics is consumed while these devices are turned off or idling? Techies refer to computers and related gadgets that draw power while not in use as vampire load. Turn off and unplug everything when you’re not using it. Even simpler: shut down everything and then turn off the power bar. 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 »
The Windows Experience Index Score was introduced in Windows Vista and used to give you a good idea of the capabilities of a computer. You can use a computer’s Experience Index base or sub score to help determine if it’s what you need when purchasing a new computer.
The Experience Index Score rates your computer’s components performance from 1 to 5.9 with 1 being the worst performing and 5.9 being the best. The score’s benchmarks were established when Windows Vista was released.
Base Score Explained
The base score represents the overall performance of your system as a whole, based on the capabilities of different parts of your computer, including RAM, CPU, hard disk, general graphics performance on the desktop, and 3-D graphics capability. More »
most of the DVD recorders made by LG and Panasonic are now able to record in all current DVD formats: DVD+R/+RW, DVD-R/-RW, and DVD-RAM. In addition there are more DVD recorders that are able to reccord in either DVD-R DL (double layer) or DVD+R DL (double layer) as well.
In addition, Sony offers standalone DVD recorders that can record in the DVD-R/-RW/+R/+RW formats, while Toshiba and several others have introduced DVD recorders that record in DVD-R/DVD-RW/DVD-RAM. Pioneer DVD Recorders record in DVD-R/-RW only. More »
