Open systems Interconnection (OSI) model was developed by the International Organization for Standardization (ISO)as model for a puter munications architecture, and as a framework for developing protocol standards.在開放系統(tǒng)互連(OSI)模型是由國際標(biāo)準(zhǔn)化組織(ISO)模型對(duì)計(jì)算機(jī)通信架構(gòu),以及一個(gè)框架,用于開發(fā)協(xié)議標(biāo)準(zhǔn)。6. The transport layer provides a mechanism for the exchange of data between end systems…….傳輸層提供了終端系統(tǒng)之間的數(shù)據(jù)交換。2. Two protocol architectures have served as the basis for the development of interoperable munications standards: the TCP\IP protocol suite and the OSI reference model.兩個(gè)協(xié)議架構(gòu)作為發(fā)展的基礎(chǔ)通信標(biāo)準(zhǔn):互操作的TCP / IP協(xié)議和OSI參考模型。三The physical and network access layers provide interaction between the end system and the network………物理和網(wǎng)絡(luò)訪問層提供了終端系統(tǒng)和網(wǎng)絡(luò)之間的交互作用,在這里傳輸和應(yīng)用層提供的是端到端的協(xié)議。最近,幀中繼和ATM網(wǎng)絡(luò)擔(dān)任主要角色。6. It is usually the case that the LAN is owned by the same organization that owns the attached devices ……..通常情況下,某一機(jī)構(gòu)擁有局域網(wǎng)及其附屬設(shè)備,而對(duì)廣域網(wǎng),這種情況很少,或者網(wǎng)絡(luò)中至少有一小部分是沒有所屬權(quán)的。5.Receiver will attempt to estimate the original s(t),based on r(t) and its knowledge of the medium ,producing a sequence of bits g(t)。3. Further, the transmission system may it itself be a network through which various path may be taken.此外,傳輸系統(tǒng)本身也可以是一個(gè)供不同路徑通過的網(wǎng)絡(luò)。9. The primary purpose of HTML is to describe how to format the text content of a web pageHTML的主要作用是描述一個(gè)網(wǎng)頁的文本內(nèi)容的格式。6. ●If you’ve never been on the internet before, you might not know what it is and how it really works. the word “internet” describes the network that started in 1983.如果你從未上過因特網(wǎng),你可能不知道因特網(wǎng)是什么,它是怎樣工作的,,在1983年因特網(wǎng)描述了網(wǎng)絡(luò)工作。4. To get to website you want, you need to use the correct Uniform Resource Locator, or address.你需要通過正確的URL或是網(wǎng)址來訪問你想訪問的網(wǎng)站。2. User can read text, view pictures, listen to sound, and even explore interactive……….用戶可以在萬維網(wǎng)上讀文本、看圖片、聽聲音、甚至還可以探索交互式的虛擬環(huán)境。10. In this case, the router serves as the translator between the information on your LAN and the Internet.這樣,路由器在局域網(wǎng)和互聯(lián)網(wǎng)絡(luò)間就作為信息傳遞的翻譯工具。 it is similar to a uperintelligent brighe. Routers select the bes
