WWW服務使用的協議為（）。
A、HTML
B、HTTP
C、SMTP
D、FTP
正確答案： B
解析： 本題考查與網絡服務協議有關的概念和知識。HTML（HyperlinkTextMarkupLanguage，超文本標記語言）是一種描述文檔結構的語言。HTML語言使用描述性的標記符（稱為標簽）來指明文檔的不同內容。標簽是區分文本各個組成部分的分界符，用來把HTML文檔劃分成不同的邏輯部分（或結構），如段落、標題和表格等。標簽描述了文檔的結構，它向瀏覽器提供該文檔的格式化信息，以傳送文檔的外觀特征。用HTML語言寫的頁面是普通的文本文檔（ASCII），不含任何與平臺和程序相關的信息，它們可以被任何文本編輯器讀取。HTTP（HypertextTransferProtocol，超文本傳輸協議）是應用層協議，由于其簡捷、快速的方式，適用于分布式和合作式超媒體信息系統，HTTP已被廣泛應用于WWW信息服務系統。HTTP是一種請求／響應式的協議。請求的格式是統一資源標識符（URI）、協議版本號等信息。服務器接到請求后，給出相應的響應信息。SMTP（SimpleMailTransferProtocol，簡單郵件傳輸協議）是Internet上傳輸電子郵件的標準協議，用于提交和傳送電子郵件，規定了主機之間傳輸電子郵件的標準交換格式和郵件在鏈路層上的傳輸機制。SMTP通常用于把電子郵件從客戶端傳輸到服務器，以及從某一服務器傳輸到另一個服務器。默認地，SMTP在TCP協議25號端口監聽連接請求。FTP（FileTransferProtocol，文件傳輸協議）是Internet上的一項主要服務?？梢栽诰W絡中建立一個具有一定存儲空間及訪問安全權限設置的FTP服務器，然后用戶通過FTP客戶程序連接FTP服務器，利用FTP提供的服務實現文件的"下載"或"上傳"功能。
