Plug and play implementation on PCI and AGP

[CAILYN]

I am trying to figure out what is the difference between both pci and agp. I am not able to calculate the difference here. First of what which platform act as better to for then pnp devices and does the pnp devices remains constant enable on the any motherboard. The possibilities lies in the motherboard settings. Need more information on the same.

The PCI bus was sufficient for many years, providing an amount of bandwidth for all the peripherals most users might want to attach. All except one: graphics cards and 3D games were challenging higher presentation. The PCI bus just could not handle all the information in sequence passing between the main processor and the graphics processor. As a result, Intel developed the Accelerated Graphics Port (AGP). AGP is a bus dedicated completely to graphics cards.

The bandwidth across the AGP bus is not communal with any other elements. Although PCI continues to be the bus of choice for the majority peripherals, AGP has taken over the dedicated task of graphics processing. However, a new bus technology has hit the market that just might spell the end for AGP. More on this later in the article, stay tuned.

Plug and Play (PnP) revenue that you can attach a device or insert a card into your computer and it is mechanically documented and configured to work in your system. PnP is a basic perception, but it took a concentrated effort on the part of the computer industry to make it happen. Intel twisted the PnP standard and integrated it into the design for PCI. But it wasn't until several years later that a conventional operating system, Windows 95, provided system-level sustain or maintain for PnP. The introduction of PnP accelerated the demand for computers with PCI, very quickly supplanting ISA as the bus of choice. To be fully implemented, PnP requires three things

In the PNP BIOS the core efficacy that facilitate PnP and detects PnP devices. It also reads the ESCD for configuration information in sequence on the obtainable PnP devices. In the Extended System Configuration Data the file contain all the information in sequence about what is installed in the PNP devices. And in the PnP operating system you can get the information on the any operating system, which can be as Windows XP, which supports pnp. The pnp which is handlers in this operating system will complete the configuration process, which was started by the BIOS for each PnP device.

The Interrupt requests, it is also known as hardware interrupt which is used in the various parts of the computer to get the attention of the CPU. If you are moving the mouse a number of time every time it sends an IRO to the CPU to show that it is doing some thing. Now we are having the PCI, before it each hardware element needed a separate IRQ setting. The Direct memory access, with this without consulting the CPU all the device is configured to access system memory.
