WHAT ARE PCI CARDS AND WHICH IS BETTER:

- 4 Ports Usb 2.0 Pci Card
OR
- 3 Ports Firewire IEEE 1394 Pci Card ?

Depends on what you want.

There are a far greater range of USB products than FireWire ones, but FireWire is reportedly faster (that really depends on certain configurations, but all the same)...

FireWire is mainly useful for transferring digital video from digital video cameras, but USB does just as good a job in this area, if it is available.

Also to add to Agents' info:
Definition and explanation: PCI (Peripheral Component Interconnect) is an interconnection system between a microprocessor and attached devices in which expansion slots are spaced closely for high speed operation. Using PCI, a computer can support both new PCI cards while continuing to support Industry Standard Architecture (ISA) expansion cards, an older standard. Designed by Intel, the original PCI was similar to the VESA Local Bus. However, PCI 2.0 is no longer a local bus and is designed to be independent of microprocessor design. PCI is designed to be synchronized with the clock speed of the microprocessor.

PCI is now installed on most new desktop computers and transmits 32 bits (of data) at a time in a 124-pin connection (the extra pins are for power supply and grounding) and 64 bits in a 188-pin connection in an expanded implementation. PCI uses all active paths to transmit both address and data signals, sending the address on one clock cycle and data on the next. burst data can be sent starting with an address on the first cycle and a sequence of data transmissions on a certain number of successive cycles.

The PCI specifications define two different card lengths. The full-size PCI form factor is 312 millimetres long; short PCIs range from 119 to 167 millimetres in length to fit into smaller slots where space is an issue. Like the full-size PCI, the short PCI is a high-performance I/O bus that can be configured dynamically for use in devices with high bandwidth requirements. Most current PCI cards are half-sized or smaller. There are a number of variations of PCI, including CompactPCI, Mini PCI, Low-Profile PCI, concurrent PCI, and PCI-X.
