What functions do routers perform in a network? (Choose two.)
gj
(1) Intercept datagrams sent to remote network segments between networks, playing a translated role.
(2) Select the most reasonable route to guide communications. In order to achieve this function, the router will check the routing table based on certain routing communication protocol, and the routing table lists all the nodes contained in the entire internet , the path conditions between nodes and transmission costs associated
with them. If a specific node has more than one path, then select the optimal path based on pre-determined specifications. Because a variety of network segments and their mutual connection situations may change, the routing information needs to be updated in time, which is completed by timing update or updating according to changes determined by the routing information protocol used. Each router in the network dynamically updates its routing table according to this rule to maintain effective routing information.
(3) When forwarding datagrams, in order to facilitate transferring datagrams between networks, routers will divide large data packets into appropriate sized data packets according to pre- determined specifications, and those appropriate sized data
packets will be turned into their original form when reaching the destination.
(4) Multi-protocol routers can connect and use network segments of different communication protocols , they can be used as communication connecting platforms of network segments of different communication
protocols.
