3.Which of the following protocols can be found at the application layer?()A.TelnetB.TCPC.SNMPD.UDP

4.A transport layer protocol has several responsibilities. One is to create a process-to-process (program-to-program) communication; TCP uses port (71) to accomplish this. Another responsibility of a transport layer protocol is to create a (72) and error-control mechanism at the transport level. TCP uses a sliding (73) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (74) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (75) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver.（71）A．numbersB．connectionsC．diagramsD．resources

    TCP/IP（ ）layer protocols provide services to the application（ ）running on a computer.The application layer does not define the application itself,but rather it defines（ ）that applications need--like the ability to transfer a file in the case of HTTP.In short,the application layer provides an（ ）between software running on a computer and the network itself.The TCP/IP application layer includes a relatively large number of protocols,with HTTP being only one of those.The TCP/IP（请作答此空）layer consists of two main protocol options--the Transmission Control Protocol（TCP）and the User Datagram Protocol（UDP）.

    A.application
    B.session
    C.physical
    D.transport

    答案：D
    解析：
    TCP/IP传输层协议为运行在计算机上的应用软件提供服务。应用层没有定义应用本身，而是定义了应用需要的服务，例如采用HTTP可以传输文件。简而言之，应用层提供了运行在计算机上的软件与网络之间的接口。TCP/IP应用层包括了很多的协议，HTTP仅是其中之一。TCP/IP传输层主要由两个可选的协议组成——传输控制协议（TCP）和用户数据报协议（UDP）。
