Final answer:
The PCI Interface supports two bus widths: 32 bits and 64 bits.
Step-by-step explanation:
The PCI Interface supports two bus widths: 32 bits and 64 bits.
32-bit PCI bus: This is the original implementation of the PCI interface. It uses a 32-bit data path and operates at a clock speed of 33 MHz, resulting in a maximum data transfer rate of 133 MB/s.
64-bit PCI bus: This is an extension of the original PCI interface that allows for a wider data path of 64 bits. It operates at the same clock speed as the 32-bit bus, but it can transfer data at twice the rate, reaching a maximum speed of 266 MB/s.
