Video Card

The processing of video Generally, video is a reference to the computer's ability to display data. This might include still, or moving pictures. Video may also refer to the video system components in the PC, such as a video processing card, video memory, or the monitor on which you view output. (output to your display 1) To present or show, as in 'to display the contents of a folder', or perhaps a picture. Or... 2) The overall 'look-and-feel' of the computer 'Desktop', including fonts, icons, colors, pictures, and more. Or... 3) May also be used to describe the attached monitor, or monitor settings, as in 'My display is a 17" Sony'. device) is one of the most demanding tasks for a PC . To help with the demands of video, many manufacturers supply their PCs with a specialized video device called AGP . AGP is short for Accelerated Graphics Port. It was designed specifically for handling 3-D graphics.

 

AGP

AGP has a dedicated 'channel', or ' bus A 'bus' is the group of wires, stamped conductors, and connectors that transfer data from one component to another. The 'System' bus' is part of the motherboard. All internal data flows through the system bus' to and from the CPU. Another bus type is the I/O, or 'external' bus. ', to main memory and works together with the RAM Short for Random Access Memory, RAM is memory chips used to temporarily store data until needed by the CPU. RAM is located on a direct path to the CPU and is electrical (vice mechanical), so data held in RAM can be accessed much faster than data stored on the hard disk (a mechanical device). in main memory to provide accelerated graphics Shortened to 'AGP' from Accelerated Graphics Port. AGP was designed for 3D graphics. It has a dedicated 'channel', or 'bus', to main memory and works together with the RAM in main memory to provide fast video response. The 'bandwidth' of AGP is capable of two or more times the processing speed of a PCI (plug-in card) graphics adapter. . The 'bandwidth' of AGP is capable of two or more times the processing speed of a PCI graphics adapter. AGP graphics may be built into the motherboard , or the motherboard may contain a specialized bus in which a third party AGP card may be plugged, or both, with the AGP card used to supplement the 'on-board' graphics.

For those systems without AGP For Accelerated Graphics Port. Designed for 3D graphics, AGP has a dedicated 'channel', or 'bus', to main memory and works together with the RAM in main memory to provide accelerated graphics. The 'bandwidth' of AGP is capable of two or more times the processing speed of a PCI (plug-in card) graphics adapter. support, it is common for power users to buy a third-party PCI Short for Peripheral Component Interconnect. PCI 'expansion cards' allow expansion of features of the computer. They plug into slots provided on the motherboard. PCI bus architecture is capable of 64 bit throughput, but is gradually being replaced by 'USB', and other expansion technologies. card, which plugs into the motherboard The motherboard is the 'base' into which other components are plugged. Made of a non-conductive material into which conductive circuits are 'sandwiched'. These circuits carry data from one component to another. The circuits are called 'printed circuits' because they are so thin they appear to be 'printed' on the surface. (in a PCI slot).

 

 

Video RAM - How Much?

Do not accept a system that has less than 8MB of video RAM. Because so much of the performance of your PC depends on VRAM, the amount, and type, of video RAM is important to the function of your PC. The PC display is the primary way the PC talks to you. The monitor The primary output device for display of computer data. There are several technologies used in building monitor displays, including cathode ray tube (CRT), liquid crystal display (LCD), and more recently, gas plasma, a 'flat screen' technology that allows construction of monitors so narrow (front-to-back) they can be hung on the wall. should be right for the task - as well as the card that feeds the display
