What action results from a failure to exchange information due to excessive transmission attempts when using an ARQ mode?
The checksum overflows
The connection is dropped✓پاسخ درست
Packets will be routed incorrectly
Encoding reverts to the default character set
توضیح
ARQ protocols retry a bounded number of times rather than forever, so when the retry limit is exhausted the protocol gives up on the link and the connection is dropped, requiring a new connect attempt.
