For (1) service, we need a virtual-circuit subnet. Let us see how that works. The idea behind virtual circuits is to avoid having to choose a new (2) for every packet sent. Instead,when a connection is established, a route from the(3) machine to the destination machine is chosen as part of the connection setup and stored in tables inside the (4) . That route is used for all traffic flowing over the connection, exactly the same way that the telephone system works.When the connection is released, the virtual circuit is also terminated. With connection-oriented service, each packet carries an (5) telling which virtual circuit it belongs to.
空白(2)处应选择()A、processorB、deviceC、routeD、terminal
问题
An internet is a combination of networks connected by (1). When a datagram goes from a source to a (2), it will probably pass many (3) until it reaches the router attached to the destination network. A router receives a (4) from a network and passes it to another network. A router is usually attached to several networks. When it receives a packet, to which network should it pass the packet? The decision is based on optimization: Which of the available (5) is the optimum pathway?
空白(3)处应选择()A、destinationsB、routersC、packetsD、computers

【说明】Linux是一个类似UNIX的操作系统,其功能强大,适合构建网络服务平台,提供DNS、WWW、FIT、NAT等服务。 在安装Linux前,必须对硬盘进行分区。在Linux系统中可用设备名称指定分区,命名方法是在驱动器的设备名称(/dev/had或/dev/hdb)后加上指定分区的数字,1~4代表主分区,逻辑分区从5开始编号。 若某系统使用两个IDE硬盘,第一个硬盘a分为3个分区,其中一个为主分区,另外两个为逻辑分区;第二个硬盘b分为5个分区,其中两个为主分区,另外3个为逻辑分区。那么硬盘a的主分区设备名为(1),硬盘b的第三个逻辑分区的设备名为(2)。 系统安装完成后,需要配置网卡。/etc/sysconfig/(3)是网络配置文件,提供IP地址、域名、网关等信息。
