The difference between U disk and card reader
Card reader is a special card reader, because it is very small card, but almost all of them, the reader can read these cards, and then openU disk is inserted into the USB port to read,The two are storing data
Card reader is actually a converter, that is, TF, SD and other cards converted to USB read outSo USB is not the same type of equipment (through the USB packet capture software can be seen, insert U disk and insert the TF card reader equipment is not the same type)With a reader, you can unify various memory cards into USB interfacesIn any case, unity means less trouble
The card reader is only able to read the memory card... Look what type of memory card you want to read...Digital cameras, mobile phones and so on, as long as the socket can be common.Plus the card is the same as the U disk. No difference.. But the U disk storage chip is embedded in the board
The U disk can directly store what is on the computer. The card reader is only a transmission medium. The reader has to put a memory card in it to store the data from the computer into the memory card of the card reader. The card reader itself does not have storage function.The difference between U disk and memory card is that the U disk has large capacity, large volume and fast transmission. It is used for direct transfer and storage of data. Generally independent use, easy to carry.The memory card is not used independently, he must need to use external equipment, general parasitic use, such as mobile phone, digital camera memory card to write data, with the reader will read the memory card data to a computer.From the view of function is u = card reader + memory card
U disk is their own memory, there are USB interface, you can directly plug in the computer to read and write operations.The card reader is used to plug memory cardsMemory cards are storage systems, but they don't plug into the computer directly, so there's a reader.Use a reader to connect the memory card to your computer.It's so simple
