What Does CardBus Mean?
CardBus is one of the two categories of PCMIA interfaces (with the other being PC Card) found in devices such as desktops, laptops and other similar devices. CardBus is a 32-bit interface capable of supporting higher data rates. CardBus is required in most devices for using high-bandwidth, high-speed capabilities.
Techopedia Explains CardBus
CardBus was introduced in the 1995 release of the PC Card Standard. The operating system must support 32-bit data paths in order for CardBus to function. Based on the 32-bit version of PC Card technology, it is similar in some aspects to PCI, such as in case of signaling protocols. In other words, available in the PC Card form factor, CardBus is a 32-bit, 33 MHz PCI bus. Both PCI and CardBus are supported by many chipsets. CardBus sockets are capable of operating both the 32-bit CardBus as well as 16-bit PC Cards. Based on the card properties, the adapter characteristics are programmed into the CardBus socket.
