通信接口是一种规范，用于定义通信设备之间的连接方式、电气特性、协议等细节。通信接口可以是硬件接口，也可以是软件接口。硬件接口主要包括物理接口和电气接口，用于规定通信设备之间连接的物理形式、电气信号等规格；而软件接口则主要用于规范通信设备之间的通信协议、数据格式等信息。通信接口是指连接通信设备之间进行信息传输的物理接口，其作用是将来自发送方的数字信号转换成适合传输介质的信号并送到接收方，同时将接收方传回的信号转换成适合发送方处理的数字信号。通信接口是实现数据通信的重要组成部分，它决定了不同种类通信设备之间能否互连和正常通信。

A communication interface is a specification used to define the connection methods, electrical characteristics, protocols, and other details between communication devices. The communication interface can be a hardware interface or a software interface. Hardware interfaces mainly include physical interfaces and electrical interfaces, which are used to specify the physical form and electrical signal specifications of connections between communication devices; And software interfaces are mainly used to standardize communication protocols, data formats, and other information between communication devices. Communication interface refers to the physical interface that connects communication devices for information transmission. Its function is to convert digital signals from the sender into signals suitable for transmission media and send them to the receiver. At the same time, it converts the signals returned by the receiver into digital signals suitable for processing by the sender. The communication interface is an important component of achieving data communication, which determines whether different types of communication devices can interconnect and communicate normally.
