网卡(Network Interface Card)是在物理上连接计算机与网络的硬件设备,是计算机与局域网通信介质间的直接接口。由于网络技术的不同,网卡的分类也有所不同,如大家所熟知的ATM网卡、令牌环网卡和以太网网卡等。据统计,目前约有80％的局域网采用以太网技术,因而本文将重点介绍以太网网卡。目前就以太网网卡而言,已有10Mbps、100Mbps、10/100Mbps以及千兆以太网网卡。在选购网卡是应该注意
Network Interface Card (NIC) is a hardware device that physically connects a computer to a network and is a direct interface between a computer and a LAN communication medium. Due to the different network technologies, the classification of network cards are also different, as we all know ATM network card, Token Ring network card and Ethernet network card. According to statistics, at present about 80% of LANs use Ethernet technology, so this article will focus on the Ethernet network card. At present there is 10Mbps, 100Mbps, 10 / 100Mbps and Gigabit Ethernet network card in terms of Ethernet network card. In the purchase card is should pay attention
