　　IC697CMM741以太網(wǎng)控制器(Ethernet Controller)，也被稱為網(wǎng)絡(luò)接口控制器(Network Interface Controller, NIC)或以太網(wǎng)適配器(Ethernet Adapter)，是處理和控制網(wǎng)絡(luò)中所有設(shè)備通訊的硬件設(shè)備。它通常位于計算機主板上，或者作為獨立的插卡或USB設(shè)備連接到計算機中。以太網(wǎng)控制器的主要功能是實現(xiàn)計算機與以太網(wǎng)之間的通信，負責(zé)將數(shù)據(jù)包轉(zhuǎn)換為可在以太網(wǎng)上傳輸?shù)母袷?，并通過物理連接與其他設(shè)備進行通信。

　　IC697CMM741以太網(wǎng)控制器的運行原理是通過物理層和數(shù)據(jù)鏈路層實現(xiàn)數(shù)據(jù)的發(fā)送和接收。當(dāng)需要發(fā)送數(shù)據(jù)時，以太網(wǎng)控制器將數(shù)據(jù)進行封裝，加入MAC地址等信息，然后通過物理層的信道將數(shù)據(jù)發(fā)送出去。當(dāng)接收到數(shù)據(jù)時，以太網(wǎng)控制器會進行解封裝，獲取數(shù)據(jù)內(nèi)容，并將數(shù)據(jù)交給操作系統(tǒng)進行進一步處理。

　　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.
