What is SDIO protocol?

SDIO Protocol is a widely used Bus for interfacing modem (device) to application processor (Host). SDIO Protocol is used for Data exchange between host and device. Initially, the SDIO Protocol bus used operates at 50MHz (SD2. 0) Specification. SDIO uses either 1-bit or 4-bit data transfer between host and device.

What is difference between SDIO and SD card?

It is simple, SDIO is for IO (IO functionality) and SD is only for storage (memory), the SDIO card side is able to interrupt the host processor while as SD doesnt interrupt the host side, host has to read or write to the SD card.
