PCI-X is short for PCI-eXtended. It was developed in 1998. PCI-X is a computer bus and expansion card standard that enhances the 32-bit PCI Local Bus for higher bandwidth demanded by servers. It is a double-wide version of PCI, running at up to four times the clock speed, but is otherwise similar in electrical implementation and uses the same protocol.
PCI-X has been replaced in modern designs by the similar-sounding PCI Express, with a completely different connector and a quite different logical design.
As you can appreciate in the below picture, the two long white slots are PCI-X while the small white slot is for PCI.
PCI-X offered increased speed over PCI and has steadily increased to more than 30 times that of the original PCI bus. PCI-X clock increases the frequency of the data bus from 66 MHz to 133 MHz while conventional PCI supports up to 64 bits at 66 MHz
An ExpressCard is an interface to allow peripheral devices to be connected to a computer, usually a laptop computer. ExpressCards is a hardware standard replacing PC cards or PCMCIA cards.
CardBus is the latest enhancement to the PCMCIA 5.0 or later. PMCIA stands for Asociación Internacional de Tarjetas de Memoria. CardBus was introduced in 1995 and present in laptops from late 1997 onward. The main purpose of CardBus was to extend the existing PCMCIA bus to allow more powerful devices, and also provide support for 32 Bit I/O.
PCMCIA is the short for Personal Computer Memory Card International Association. It is pronounced as separate letters. PCMCIA is also known as PC Card.
PCMCIA was originally designed for adding memory to portable computers, the PCMCIA standard has been expanded several times and is now suitable for many types of devices
The primary advantage of AGP over PCI is that it provides a dedicated pathway between the slot and the processor rather than sharing the PCI bus. In addition to a lack of contention for the bus, the point-to-point connection allows for higher clock speeds.
PCI-X is the upgraded version of PCI. It differs mainly in the fact that the PCI-X bus is 64-bits wide, and runs at higher frequencies of up to 533MHz, compared to PCI frequency that runs up to 66MHz.
AGP Pro was launched in 1998 as an AGP interface extension specification for advanced workstations. AGP Pro bus is a specification that provides a direct connection between the graphics adapter and memory.
ISA is an old technology that has been replaced by PCI, PCIe and so on. ISA slots are usually black, long and the gold contacts are large.
