How Graphics Cards Work"

How Graphics Cards Work"
The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card. A graphics card's job is complex, but its principles and components are easy to understand. In this article, we will look at the basic parts of a video card and what they do. Think of a computer as a company with its own art department. A graphics card works along the same principles. Creating an image out of binary data is a demanding process. The graphics card accomplishes this task using four main components: Next, we'll look at the processor and memory in more detail. Related:  Tech Tips / LearnTech Pro

Understanding Chipsets: What is a Chipset, Anyway? - Gamers Nexus - Your hub for gaming hardware, news, PC builds, and reviews Known for having the coolest-sounding naming scheme in computing, chipsets operate at the core of every build we do here at GN -- by this point, all of you know the basics: P67 is good, Z68 is better, X79 (SB-E) is expensive; the 970 is good, the 990X is great, and AM3+'s 990FX is expensive (sort of). Great, so we have an idea of what to get relative to other chipsets, but that doesn't mean much. That's about as useful as knowing "DDR3 is better than DDR2," without truly knowing why. It's brochure knowledge. As we did with our GPU dictionary and SSD dictionary, this chipset guide will help explain what, exactly, a chipset is responsible for and what you should look for in future editions. This helps keep everyone on the cutting edge as new technology is announced and, better still, helps you actually understand what is needed, not just recommended.

How To Not Get Sued for File Sharing (And Other Ideas To Avoid Being Treated Like a Criminal) As of July 2006, the Recording Industry Association of America (RIAA) has sued over 20,000 music fans for file sharingin just under three years. In 2004, the Motion Picture Association of America (MPAA) joined this misguided, anti-consumer crusade. Filing lawsuits against anonymous "Doe" defendants, the RIAA and MPAA seek to uncover the identities of P2P users and force them to pay thousands of dollars in settlements. Many innocent individuals are being caught in the crossfire. While there is no way to know exactly what the RIAA and MPAA are going to do or who they are going to sue, users of publicly-accessible P2P networks can take the following steps to reduce their chances of being sued: Either: Make sure there are no potentially infringing files in your shared folder. Or: Note: Not all clients allow you to turn off "sharing." Additional Considerations: What if I've Already Been Sued? These links may provide helpful information:

Civic Networks: Building Community On the Net - An Article by Scott London All sorts of reasons have been advanced in recent years to explain the decline of community in America, including the way we design our neighborhoods, the increased mobility of the average American, and demographic shifts like the movement of women into the labor force. But the onslaught of television and other electronic technologies is usually cited as the main culprit. As Harvard sociologist Robert Putnam puts it, these technologies are increasingly "privatizing our leisure time" and "undermining our connections with one another and with our communities." This essay appears in the book Composing Knowledge, edited by Rolf Norgaard (Bedford/St. In his essay "The Strange Disappearance of Civic America," Putnam draws a direct parallel between the arrival of television and the decline of what he calls "social capital" — the social networks, trust, and norms of reciprocity that are the essence of healthy communities.

How to Hunt Elephants MATHEMATICIANS hunt elephants by going to Africa, throwing out everything that is not an elephant, and catching one of whatever is left. EXPERIENCED MATHEMATICIANS will attempt to prove the existence of at least one unique elephant before proceeding to step 1 as a subordinate exercise. PROFESSORS OF MATHEMATICS will prove the existence of at least one unique elephant and then leave the detection and capture of an actual elephant as an exercise for their graduate students. COMPUTER SCIENTISTS hunt elephants by exercising Algorithm A: Go to Africa. EXPERIENCED COMPUTER PROGRAMMERS modify Algorithm A by placing a known elephant in Cairo to ensure that the algorithm will terminate. ASSEMBLY LANGUAGE PROGRAMMERS prefer to execute Algorithm A on their hands and knees. DATABASE ADMINISTRATORS do not need to go out and capture elephants when they can retrieve them simply with an ad hoc query: STATISTICIANS hunt the first animal they see N times and call it an elephant. - Portable software for USB, portable and cloud drives Online Books : "The Essential Psychedelic Guide" - Ecstasy INTENSITY: 2 to 4 MATERIAL: Ecstasy is a synthetic compound developed in 1914 as a potential dietary aid. However, its psychoactive effects were not discovered until the mid-Seventies. It was used widely in therapy from this time until 1985 when it was made illegal. Its chemical name is 3,4-methylenedioxymethamphetamine (MDMA), commonly known as "X", "E", or "Adam." It usually comes as a white crystalline powder or made into tablets. DOSAGE: 125 mg. (1/8th of a gram) is generally considered a single dose of ecstasy. THE HIGH: When ecstasy is coming on it feels fantastically exhilarating. Most X users report that their first couple of experiences are like being in heaven, and leave a strong impression. Ecstasy is not really "psychedelic" in the same way as other substances in this journal. Ecstasy rarely produces a bad experience, but there are some negative aspects to ecstasy's signature. I've read numerous clinical articles on ecstasy. See the 2C-B chapter. 1.
