Running more than one application at a time is called what?

Multitasking refers to the ability of a computer system to run multiple applications or processes simultaneously. This capability allows users to switch between different tasks, such as listening to music while browsing the web, enhancing productivity and user experience. The operating system manages the resources and time allotted to each application, ensuring that they all function effectively without interfering with one another.

While terms like simultaneous processing and concurrent execution might seem related, multitasking is the widely recognized term specifically used to denote the ability to run more than one application at a time, emphasizing the user's experience and interaction with the system. Run-time management, while it might involve overseeing applications during their execution, does not specifically capture the essence of running multiple applications simultaneously in the context typically applied to users' tasks.
