The card reader is produced in conjunction with digital cameras, but its use is no longer limited to digital cameras, but has expanded to more fields. Let's follow the editor of explosion-proof card reader from China to have a simple understanding!
The card reader, as the name suggests, is a device that reads data, but it not only supports data reading but also supports data writing. The initial design idea is mainly to make up for the defects of digital camera data output. Since the USB interface was not popular in the early days, the output ports of digital cameras were all connected to the serial port of the computer. Since the data transmission speed of the serial port was very low, it would take a lot of waiting time to copy these data to the hard disk. , Therefore, the card reader came into being. With the development of digital products such as MP3 and PDA, the development of card readers has been strongly promoted. The standard 256M or 512M flash memory of MP3 is obviously not enough to meet our needs, so adding 1G or higher flash memory has become our standard configuration, but if we want to copy MP3 songs to the flash memory, we can only play through MP3. At this time, we need a dedicated connection, driver and software to complete, so the portability of MP3 players is much worse, and if we use a card reader at this time, there is no need for MP3 playback. With the intervention of the device, you can directly store MP3 songs on the flash memory, so that MP3 becomes more convenient to use.
The above is the explosion-proof card reader from China editor: a brief introduction to the relevant knowledge of the card reader.
