　　IC697CMM741以太网控制器(Ethernet Controller)，也被称为网络接口控制器(Network Interface Controller, NIC)或以太网适配器(Ethernet Adapter)，是处理和控制网络中所有设备通讯的硬件设备。它通常位于计算机主板上，或者作为独立的插卡或USB设备连接到计算机中。以太网控制器的主要功能是实现计算机与以太网之间的通信，负责将数据包转换为可在以太网上传输的格式，并通过物理连接与其他设备进行通信。

　　IC697CMM741以太网控制器的运行原理是通过物理层和数据链路层实现数据的发送和接收。当需要发送数据时，以太网控制器将数据进行封装，加入MAC地址等信息，然后通过物理层的信道将数据发送出去。当接收到数据时，以太网控制器会进行解封装，获取数据内容，并将数据交给操作系统进行进一步处理。

　　IC697CMM741 Ethernet Controller, also known as Network Interface Controller (NIC) or Ethernet Adapter (Ethernet Adapter), It is the hardware device that processes and controls the communication of all devices in the network. It is usually located on the computer motherboard, or connected to the computer as a separate card or USB device. The main function of the Ethernet controller is to realize the communication between the computer and the Ethernet, which is responsible for converting data packets into a format that can be transmitted on the Ethernet network, and communicating with other devices through physical connections.

　　The operating principle of the IC697CMM741 Ethernet controller is to transmit and receive data through the physical layer and data link layer. When data needs to be sent, the Ethernet controller encapsulates the data, adds information such as the MAC address, and then sends the data through the channel at the physical layer. When the data is received, the Ethernet controller unpacks it, obtains the data content, and passes the data to the operating system for further processing.
