Which term describes processes that execute during overlapping time periods with potential resource conflicts?

• A. Concurrent Processes
• B. Serial Processes
• C. Batch Processes
• D. Real-Time Processes

Answer: (A)

Concurrence is about multiple tasks making progress at overlapping times. When several processes run during overlapping time periods, they may compete for shared resources like CPU time, memory, or I/O devices, which can introduce conflicts if not coordinated. This overlap is what makes them concurrent—they may run truly at the same instant on multi-core hardware or be interleaved on a single processor. Serial processes, by contrast, execute one after another with no overlap. Batch processes often run in groups and may be scheduled in a way that isn’t interactive or overlapping in the same sense. Real-time processes are judged by whether they meet timing deadlines, not strictly by whether their execution overlaps. So the description fits concurrent processes best: overlapping execution with potential resource conflicts requiring synchronization.
