FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards.

Detailed explanation-2: -AGP, in full accelerated graphics port, graphics hardware technology first introduced in 1996 by the American integrated-circuit manufacturer Intel Corporation.

Detailed explanation-3: -AGP is a port (it only connects two nodes) while PCI is a bus. AGP does not replace the PCI bus, it is a dedicated connection that can be used only by the graphics subsystem. AGP and PCI also differ in terms of their minimum length and alignment requirements for transactions.

Detailed explanation-4: -(Accelerated Graphics Port) An earlier hardware interface from Intel for connecting a graphics card (display adapter) to a PC. Introduced in 1997 and superseded by PCI Express in the late 2000s, a single AGP slot on the motherboard provided a direct connection between the card and memory.

Detailed explanation-5: -AGP Connectors And Slots Each AGP card has one or two slots in its card edge. If a video card has the 3.3 volt slot, then it can use 3.3 volt signaling. AGP 2.0 added the 1.5 volt slot on cards which could use 1.5 volt signaling. If the card has both slots then it can use both signaling voltages.
