Digital data can also be represented by（71）signals by use of a modem. The modem converts a series of binary voltage （72） into an analog signal by encoding the digital data onto a carrier frequency. The resulting signal occupies a certain spectrum of （73） centered about the carrier and may be propagated across a' medium suitable for that carrier. The most common modems represent digital data ..

OSPF is a link-state routing protocol. It is designed to be run internal to a single (71) system. Each OSPF router maintains an identical (72) describing the autonomous system's topology. From this database, a routing table is calculated by constructing a shortest-path (73) . OSPF recalculates routes quickly in the face of topological changes, utilizing a minimum of routing (74) traffic. OSPF prov..
