Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time.
The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information.

Why is multitasking important in an operating system?
Usually, modern multitasking OSs also provide memory isolation between processes and support different security levels, allowing OS code to do things user code cannot. A Multi-Tasking Operating System would be an OS that allows for the simultaneous execution of multiple (more than 1) processes.
How does the operating system manage memory and CPU time to allow the computer to multitask?
Multitasking is the mechanism by which the CPU of a computer is able to handle multiple tasks at the same time. During multitasking, the common resources like CPU and memory, are shared and this can cause a delay or latency in the execution of programs.
How does preemptive multitasking work?
Preemptive multitasking is a type of multitasking that allows computer programs to share operating systems (OS) and underlying hardware resources. It divides the overall operating and computing time between processes, and the switching of resources between different processes occurs through predefined criteria.
