Plug and play completion on PCI and AGP

I am attempting to make out what is dissimilarity among both pci and agp. Which platform perform better to for then pnp devices and does pnp devices stays steady enable on any motherboard. The option lies in motherboard settings.

1) PCI bus was enough for many years, giving an amount of bandwidth for all peripherals many users desire to connect. Apart from one graphics cards and 3D games were challenging higher presentation. PCI bus could not hold all data in sequence passing between main processor and graphics processor. As result, Intel made Accelerated Graphics Port (AGP). AGP is bus devoted entirely to graphics cards.

2) Bandwidth across AGP bus is not shared with any other elements. Though PCI keep on to be bus of choice for majority peripherals, AGP has taken over devoted task of graphics processing. Though, new bus technology has hit market that spell end for AGP.

3) Interrupt requests, is known as hardware interrupt which is utilized in different parts of PC to get awareness of CPU. If you are moving mouse many time each time it sends IRO to CPU to display that it is doing some thing. Now we are having PCI, before it every hardware element required individual IRQ setting. Direct memory access, with this without consulting CPU all devices is organized to access system memory.
