how does a SD card works?explain in detail,..
Hello,
SD cards are a type of flash memory that may be used to store data from a variety of current digital devices. They are unique among storage media in that they may be written to thousands of times and do not require electricity to save their contents. This makes them an excellent choice for gadgets like digital cameras, which demand high levels of power and require media that can be written to numerous times. SD cards, unlike traditional hard drives, have no moving components and are therefore far more resistant to accidental knocks and falls. This has aided their adoption in MP3 players, which are frequently subjected to shock.
The data on an SD card is stored on NAND chips, which are a type of electrical component. Data may be written to and saved on the SD card using these devices. Data can be transmitted from the cards quickly since the chips have no moving components, considerably faster than CD or hard-drive media. Because SD cards' NAND chips do not quickly wear out, data may be written to them thousands of times over their lifespan, making them durable and long-lasting in use.
