However, when the number of communication connection ports is reduced, the hub that can be connected to external hardware will be very smooth, but most of the memory storage devices connected to the hub are only for simple external devices. Card readers, hard disks, and CD-ROMs are used on hardware, and the memory storage devices used by external card readers can be divided into MMC, CF, SM, SD, MD and other types. When you want to read different types of When using a memory storage device, it is necessary to purchase a relatively large number and types of card readers for use, which makes the cost of purchasing hardware for consumers very considerable. In addition, the general external hardware CD-ROM drive and card reader currently need to be properly connected to the computer before they can be used. Use, and it is easy to cause inconvenience to consumers in operation. When accessing or transmitting data of the same or different types of memory storage devices, it is generally a stand-alone external card reader, hard disk, and CD-ROM drive or a computer. The card reader, hard disk, and CD-ROM installed in it are stretched. From the above, it can be seen that all kinds of commonly used devices have the shortcomings of narrow applicability, high purchase cost, and inconvenient use.
