What are the differences between VGA, DVI, RS232, UART, SCSI, SATA, and other interfaces?
Both VGA and DVI are video transmission lines. The former is a traditional analog transmission, and the latter has many types, which only transmits numbers or analog or digital models. In short, the latter's video signal transmission quality is higher than the former, and the transmission speed is faster. At present, many monitors on the market use DVI interfaces (including HDMI, HDTV, And the Displayport of cleui)
Interfaces are very easy to differentiate:
RS232 should be a protocol standard. It is an interface standard for serial data communication developed by the US Electronic Industry Alliance (EIA. You can simply think that UART is a practical application of RS232.
UARTThis is what we usually call the serial port. Asynchronous, serial. Generally, it is used with maxcompute to convert the level to the 232 level that the PC can receive or convert the 232 level output by the PC to the TTL level that the microcontroller can receive. In addition, the serial port debugging assistant will be used during debugging to implement many functions and make it easy to use.
SCSISmall Computer System Interface (Small Computer System Interface), used between a Computer and a smart device (hard disk, soft drive, optical drive, printer, scanner, etc) independent processor standard for system-level interfaces. SCSI is an intelligent universal interface standard.
SATAIt is a hard drive interface that we are familiar with, including traditional hard drives and solid state drives.
These are all very well differentiated, because they are completely different in terms of appearance.
