In computing, time-sharing is the concurrent sharing of a computing resource among many tasks or users by giving each task or user a small slice of processing time. This quick switch between tasks or users gives the illusion of simultaneous execution.
iPadOS is a mobile operating system developed by Apple for its iPad line of tablet computers.It was given a name distinct from iOS, the operating system used by Apple's iPhones to reflect the diverging features of the two product lines, such as multitasking.
Time-sharing was first proposed in the mid- to late-1950s and first implemented in the early 1960s. The concept was born out of the realization that a single expensive computer could be efficiently utilized by enabling multiprogramming, and, later, by allowing multiple users simultaneous interactive access.

Alongside dropping support for the iPad Mini 4, the iPad Mini (5th generation) is the only supported iPad with the exclusive 7.9-inch display.
The term "preemptive multitasking" is sometimes mistakenly used when the intended meaning is more specific, referring instead to the class of scheduling policies known as time-shared scheduling, or time-sharing. Preemptive multitasking allows the computer system to more reliably guarantee each process a regular "slice" of operating time.
Multitasking may refer to: Computer multitasking, the concurrent execution of multiple tasks (also known as processes) over a certain period of time Cooperative multitasking; Pre-emptive multitasking; Human multitasking, the apparent performance by an individual of handling more than one task at the same time
Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car. Multitasking can result in time wasted due to human context switching (e.g., determining which step is next in the task just switched to) and becoming prone to errors due to ...
