Slots

The AGP slot allows you to insert the AGP graphics card. AGP is an interface speci-

fication designed for the throughput demands of 3D graphics. It introduces a 66MHz,

32-bit channel for the graphics controller to directly access main memory.

The PCI slots support LAN cards, SCSI cards, USB cards, and other add-on cards

that comply with PCI specifications. At 32 bits and 33 MHz, it yields a throughput rate

of 133 MBps.

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines

over which devices can send interrupt signals to the microprocessor. The PCI IRQ
