Video Cards
A video card is an expansion card that is made to generate and output images to display. A lot of video cards offer added functions like rendering 3D scenes, video capture, TV turner adapter, MPEG-2 and MPEG-4 decoding, FireWire, light pen, TV output, or the ability to connect multiple monitors. The first video card made by IBM PC was made in 1981.
The MDA could only work in text mode representing 80 columns and 25 lines in the screen. It had a 4KB video memory and was made in just one color. Later more video cards were made with MDA. Then there was some that was with VGA and S3 and more colors were able to be used. In 1995 that’s when the 2D and 3D ones were made. Video cards use a lot of electricity and that make a lot of heat.
If the video card gets over heated it can be damaged. That’s why there are cooling devices to help that problem. The three that are most commonly used for the video cards are the heat sink, the computer fan, and the water block. The heat sink is a passive cooling device. It keeps the heat away from the pictures card’s core, or memory by using a heat metal. This is usually copper or aluminum. The computer fan is usually jus a fan that is changed often for quicker cooling.
The water block a heat sink suited to use water instead of air. The water is pumped through the water block and transfers the heat into water and that makes it cool. This is the most effective cooling solution they use. Video card also use a lot of power. Video cards are great to use when you like to display a lot of pictures.

Toronto Rocks $18.41 Like most festival shows, the Toronto Rocks concert, a SARS benefit held on July 30, 2003 before a teeming crowd of 490,000, is a pretty mixed bag. For one thing, the Guess Who, Rush, AC/DC, and the Rolling Stones–the headliners–are all well past their primes. They’re still kicking, of course, and fans of each will relish their sets.
