Less time delays speeds up your work and allows you to get more done in a shorter period of time. Video cards are actually a small computer designed specifically to perform the video function. Video cards have a processing chip designed specifically for the video display function similar to the central processing unit or CPU found on the motherboard. The better video boards have 128-bit processing function. Video boards also have read only memory or RAM just like the CPU that speeds the process of the video board and saves the video board relying on system RAM that can be saved to speed up the processing of the computer itself.
Video boards come in various types.
Currently the best video boards are Accelerated Graphics Port or AGP compatible. The AGP main memory use is dynamic, meaning that when not being used for accelerated graphics, main memory is restored to use by the operating system or other applications. Video cards that are only expected to display 2-D or two dimensional images will limit the user in displaying multimedia presentations which include movies and videos that can be used to illustrate learning tapes or other images. Computers will be using more and more 3-D applications in business programs. Many applications have screens that are too dark or too light or simply need some adjustment to the picture position or size to become more easily viewed.
