Parallel (simultaneous) refers to processes or actions occurring at the same time. In various fields, such as computing and physics, parallelism allows multiple tasks to be executed concurrently, improving efficiency and speed. For example, in a computer, multiple processors can work on different parts of a problem simultaneously. In everyday life, parallel activities can be seen when people multitask, like cooking while talking on the phone. This concept is essential in many areas, including project management, where teams work on different aspects of a project at once, or in telecommunications, where multiple calls can be handled simultaneously.
