计算机的接口有很多,按数据传输方式的不同可以分为“并口”和“串口”两种,相信用过电脑的人都不会感到陌生。顾名思义,所谓的并口是指数据并行传输的接口,而串口则是数据串行传输的接口。
There are many computer interfaces, according to the different ways of data transmission can be divided into “parallel port ” and “serial port ” two, I believe that people who have used the computer will not feel strange. As the name suggests, the so-called parallel port refers to the parallel data transmission interface, and serial data interface is the serial transmission.
