  • 第1题:

    Asynchronous Transfer Mode(ATM)is a(16)that promises to change the fabric of local and wide area communications.The key advantage of ATM is the capability to move voice, data, graphics and(17)at speeds of up to 2 gigabits per second.An ATM switch allows you to create a(18)network that is completely independent from the(19)configuration of the network.ATM uses a(20)called cell switching to convert data into fixed length cells of 53 bytes each, so they can be switched very quickly and efficiently.

    A.technology

    B.video images

    C.logical

    D.physical


    正确答案:A

  • 第2题:

    For each blank, choose the best answer from the four choices and write down on the answer'sheet.

    (66)is a protocol that a host uses to inform. a router when it joins or leaves an Internet multicast group.

    (67)is an error detection code that most data communication networks use.

    (68)is an interior gateway protocol that uses a distance vector algorithm to propagate routing information.

    (69)is a transfer mode in which all types of information are organized into fixed form. cells on an asynchronous or non-periodic basis over a range of media.

    (70)is an identifier of a web page.

    A.ICMP

    B.SMTP

    C.IGMP

    D.ARP


    正确答案:C
    解析:IGMP协议是接收者发现协议。IGMP协议运行在主机和路由器之间,用于路由器维护组播组是否有组成员。IGMP只维护组播组是否有成员,而不维护组播组有哪些成员,因此状态信息不会因组播组成员的增加而增加。
      循环冗余校验(cyclic redundancy check,CRC)是由分组线性码的分解而来,其主要应用是二元码组,主要应用于数据传输过程中的差错控制。
      OSPF是一个内部网关协议(Interior Gateway Protocol,IGP),用于在单一自治系统 (autonomous system,AS)内决策路由。与RIP相对,OSPF是链路状态路由协议,而RIP是距离向量路由协议。它是依靠距离,即跳数来衡量一条路径的好坏。通过距离向量路由算法来传播路由信息。
      ATM是异步传输模式,实现OSI物理层和链路层功能。ATM以独有的ATM信元进行数据传输,每个ATM信元为53个字节。ATM不严格要求信元交替地从不同的源到来,每一列从各个源来的信元,没有特别的模式,信元可以从任意不同的源到来,而且不要求从一台计算机来的信元流是连续的,数据信元可以有间隔,这些间隔由特殊的空闲信元(idle cell)填充。
      URL(Uniform. Resource Locator)是单一资源定位符,是一种用来鉴别文件与资源在WWW中地址的专用表示。
