Why each option
SD (Secure Digital) cards are non-volatile flash memory storage devices commonly used in portable consumer electronics such as mobile phones and digital cameras.
SD cards are widely used as removable storage media in mobile phones, digital cameras, tablets, and other portable devices due to their compact form factor and ease of data portability.
SD cards use NAND flash memory, which is non-volatile - meaning stored data is retained even when power is removed, making them suitable as persistent storage media.
184-pin connectors are associated with DDR SDRAM desktop memory modules, not SD cards, which use a small edge connector with far fewer electrical contacts.
SD cards are flash-based storage devices and cannot be used as system RAM - they are far too slow and use a different interface than the memory bus required by a CPU.
