What Is a MultiMedia Card and How Is It Used in Digital Photography?

A MultiMedia Card, also known as an MMC, is a form of solid-state memory introduced by SanDisk in 1997. Measuring 24 mm × 32 mm × 1.4 mm a MultiMedia Card is similar in size and shape to an SD card. MultiMedia cards have been used in many digital cameras since their introduction. The introduction of the SD card has seen a decline in use of the MultiMedia Card, but many devices with an SD card slot support the use of MultiMedia Cards so there is no need to throw away those old memory cards just yet!
