What is the difference, if any, between a UART port and a serial port in a computer?

UART端口和計算機中的串行端口之間有什么區別?

#1


UART is the abbreviation of Universal Asynchronous Receiver Transmitter, the name of the chip that enables the computer to communicate via a serial line (eg. RS-232, RS-485, RS-422).

UART是通用異步接收器發送器的縮寫,是使計算機能夠通過串行線路(例如RS-232,RS-485,RS-422)進行通信的芯片名稱。

The serial port is the RS-232 interface (internally connected to the UART) of the computer.

串行端口是計算機的RS-232接口(內部連接到UART)。

As @SurDin explained some more points I want to add
1.UART takes data parallel and the help of shift register transfer it bit by bit or takes data bit by bit and reform those into parallel form via communication channel like RS-232,RS-485,RS-422.
2.UART has a baud rate generator, transmeter and a receiver.
3.Its baud rate generator gets clocked either by internal clock or by external source.
communication media linked to serial port which internally connected to UART controller.

由於@SurDin解釋了我想要添加的更多要點1.UART采用並行數據並且移位寄存器的幫助將其逐位傳輸或逐位獲取數據並通過RS-232,RS等通信通道將它們轉換為並行形式485,RS-422。 2.UART有一個波特率發生器,轉換器和接收器。 3.波特率發生器由內部時鍾或外部源提供時鍾。連接到串行端口的通信介質,內部連接到UART控制器。
