[单项选择]One of the most widely used routing protocols in IP networks is the Routing Information Protocol (RIP). RIP is the canonical example of a routing protocol built on the (71) algorithm. Routingprotocols in internetworks differ slightly from the idealized graph model. In an internetwork, the goal ofthe routers to forward (72) to various networks.
Routers running RIP send their advertisement abOLit cost every (73) seconds. A router also sends an up date message whenever an update from another router causes it to change its routing table.
Routing protocols use different techniques for assigning (74) to individual networks. Further, each routing protocol forms a metric aggregation in a different way. RIP takes the simplestapproach, with all link costs being equal (75) . Thus it always tries to find the minimum hop route. Valid distances are 1 through 15. This also limits RIP to running on fairly small networks.
A. Dijkstra
B. path-vector
C. link-state
D. distance-vector
[简答题] Most Americans spend far more of their leisure time with the mass media than in any other occupation. In addition, most of us hear, see, or read some of the media while engaged in other activities. Thus an extremely large number of our waking hours are spent with the mass media. Of all the media, television is clearly dominant, with newspapers a close second, at least as a source of news and other information. Our exposure to all media is important, however, because all of them contribute materials for the construction of that world in our heads. For most people, increased use of one medium does not decrease use of another. In fact, in certain cases, and especially for certain purposes, the more one uses one medium, the more likely one is to use others.
There are various factors that can cause you to expose yourself to the media selectively, avoiding much of the material with which you disagree. Some of that selective exposure is probably due to the psychological pressure you
