===Memory cards===
Although many early PDAs did not have [[memory card]] slots, later models had either some form of [[Secure Digital]] (SD) slot,<ref name="lenovo"/> a [[CompactFlash]] slot or a combination of the two. Although designed for memory, [[Secure Digital Input/Output]] (SDIO) and CompactFlash cards were made available that provided [[peripheral]] accessories like Wi-Fi or digital cameras to devices with software support. Some PDAs also have a USB port, mainly for [[USB flash drive]]s.{{Dubious|date=August 2010}}  Some PDAs use [[microSD]] cards, which are electronically compatible with SD cards, but have a much smaller physical size.
