How Concurrency and multitasking differs?

Answer 1

Concurrency refers to the ability of a system to manage multiple tasks at the same time, allowing them to make progress independently, often by interleaving their execution. In contrast, multitasking specifically refers to the execution of multiple tasks or processes by a single processor, where the processor switches between tasks rapidly to give the illusion of simultaneous execution. Concurrency can occur in systems with multiple processors, while multitasking is typically associated with a single processor managing multiple tasks. Thus, while all multitasking can be considered a form of concurrency, not all concurrency involves multitasking in the traditional sense.
