Answer Posted / Ishwar Singh Gwal
A job in MapReduce represents the high-level processing of a user's workflow, consisting of multiple map and reduce tasks. Each task processes data in parallel by splitting it into several input splits, performing the map or reduce operation on each split, and then shuffling and sorting the output. Tasks are executed on worker nodes in response to job requests from the client.
