接口的工作模式 以太網(wǎng)卡可以工作在兩種模式下：半雙工和全雙工。 半雙工：半雙工傳輸模式實(shí)現(xiàn)以太網(wǎng)載波監(jiān)聽多路訪問沖突檢測(cè)。傳統(tǒng) 的共享LAN是在半雙工下工作的，在同一時(shí)間只能傳輸單一方向的數(shù)據(jù)。當(dāng)兩個(gè)方向的數(shù)據(jù)同時(shí)傳輸時(shí)，就會(huì)產(chǎn)生沖突，這會(huì)降低以太網(wǎng)的效率。 全雙工：全雙工傳輸是采用點(diǎn)對(duì)點(diǎn)連接，這種安排沒有沖突，因?yàn)樗鼈? 使用雙絞線中兩個(gè)獨(dú)立的線路，這等于沒有安裝新的介質(zhì)就提高了帶寬 。例如在上例的車站間又加了一條并行的鐵軌，同時(shí)可有兩列火車雙向 通行。在全雙工模式下，沖突檢測(cè)電路不可用，因此每個(gè)全雙工連接只 用一個(gè)端口，用于點(diǎn)對(duì)點(diǎn)連接。標(biāo)準(zhǔn)以太網(wǎng)的傳輸效率可達(dá)到50%～60% 的帶寬，全雙工在兩個(gè)方向上都提供100%的效率。
