Graphics cards for PCs
The two elementary interfaces between man and computer are the keyboard and the mouse for manual data entry, and the monitor which basically returns the computer's response to our input actions. For an analogue peripheral device like the monitor to visualize computer data, an adapter is required which converts the digital computer signals into a form that is comprehensible by the display. This, basically, sums up the function of a graphics, or video, card fitted in a PC. Because video card manufacturers release faster and better VGA cards all the time, keeping track of market developments has become difficult if you want to make an informed choice.
