140CPS11420C Quantum

140CPS11420C通信網(wǎng)絡(luò)的核心是OSI（開放式系統(tǒng)互聯(lián)）參考模型。1984年，國際標(biāo)準(zhǔn)化組織（ISO），提出的開放式系統(tǒng)互聯(lián)的七層模型。OSI模型自下而上分為：物理層、數(shù)據(jù)鏈接層、網(wǎng)絡(luò)層、傳輸層、會話層、表示層和應(yīng)用層。（也可把5、6、7層作應(yīng)用層）   

（1）物理層（Physical Layer）：定義了傳輸介質(zhì)、連接器和信號収生器的類型，規(guī)定了物理連接的電氣、機(jī)械功能特性，如電壓、傳輸速率、傳輸距離等特性。典型的物理層設(shè)備有集線器（HUB）和中繼器等。有了物理層，就可以通過線路跟另一臺電腦交流。 

（2）數(shù)據(jù)鏈路層（Data Link Layer）：確定傳輸站點(diǎn)物理地址以及將消息傳送到協(xié)議棧，提供順序控制和數(shù)據(jù)流向控制。典型的數(shù)據(jù)鏈路層的設(shè)備有交換機(jī)和網(wǎng)橋等。 

MAC地址屬于數(shù)據(jù)鏈路層，相當(dāng)于人的身份證。有了這一層，發(fā)送過去的比特流可以得到檢測這樣就不會出現(xiàn)錯誤的信息了。
