4.● A glue that holds the whole Internet together is the network layer protocol,(71). Unlike most older network layer protocols, it was designed from the beginning with internetworking in mind. Its job is to provide a -(72) way to transport datagrams from source to destination, without regard to whether these machines are on the same network or whether there are other networks in between them.Communication in the Internet works as follows. The (73)layer takes data streams and breaks them up into datagrams. Each datagram is transmitted through the Internet, possibly being fragmented into smaller units as it goes. When all the pieces finally get to the destination machine, they are reassembled by the(74) layer into the original datagram. This datagram is then handed to the transport layer, which inserts it into the receiving process' input stream.An IP datagram consists of a header part and a text part. The header has a (75) part and a variable length optional part.(71) A. IP (Internet Protocol)B. IP (Interworking Protocol)C. TCP (Transport Control Protocol)D.

    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（请作答此空）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（ ）layer consists of two main protocol options--the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).

    A.iteration
    B.object
    C.interface]
    D.activity

    答案：C
    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)。
