An application running on a typical operating system is best described as a process. Many processes may be active at the same time. Only one process can actually be running at a time.
Multitasking is a fundamental feature of modern operating systems, allowing multiple applications to run concurrently on a single computer. Process scheduling is the method by which the OS determines which processes, or applications, are given access to the system's resources at any given time. The OS uses a scheduler to allocate CPU time to each process, switching rapidly between them to give the illusion of simultaneous execution. This is known as time-sharing.
