Mainly include: IDE electronic integrated drive, SCSI small computer system connection, fiber channel, SATA serial hard disk, RAID card, MD device, and finally the USB and Type-C double-sided pluggable interface that everyone knows better is for PC and digital equipment Technology developed to transfer data between. These hardware interfaces are widely used in information communication products such as computers and mobile devices. Let's take a look at the classification of common interfaces in this article: infrared, DB, PCI, serial, PS/2, Dock, RJ11, RJ45, RF, AV, DIN, VGA, DVIH, DMI, BNC, RCA analog audio, S /PDIF, XLR, SM card, MMC card, SD card, XD card and other interfaces, these interfaces are used between the device software.
