Final answer:
Concurrent processes implement interleaving by running processes simultaneously, allowing multiple processes to progress concurrently and make progress on their tasks. The correct answer is B.
Step-by-step explanation:
Concurrent processes implement interleaving by running processes simultaneously. Interleaving is the execution of multiple processes in an overlapping manner, where they take turns to execute one instruction at a time. This allows multiple processes to progress concurrently and make progress on their tasks. Each process is given a small time slice, called a quantum, during which it executes. The operating system then switches between the processes, giving the illusion that they are running simultaneously.
Concurrent processes implement interleaving by running processes simultaneously, which allows multiple processes to advance by quickly alternating execution within a shared CPU environment.
The student asked how concurrent processes implement interleaving. The correct answer is b. By running processes simultaneously. In concurrent computing, interleaving means that processes take turns executing their instructions in a shared CPU environment. It appears as if operations are occurring simultaneously, because the context switches between processes are fast and occur at a granular level. This allows multiple processes to advance without waiting for each other to complete. It is important to note that while processes appear to be running at the same time, the actual execution within a single-core CPU is not simultaneous but is quickly alternated (interleaved) to give the illusion of concurrency.
