A multitasking operating system is an operating system that allows a user to perform more than one computer task simultaneously. Multitasking is the concurrent execution of multiple tasks (also known as processes) over a certain period of time. Multiple tasks are also known as processes that share similar processing resources like a CPU. The operating system keeps track of where you are in each of these jobs and allows you to transition between them without losing data. Multitasking operating systems give more flexibility to several users, and they are happier as a result. Key features of multitasking operating systems include:

  • Background Processing: A multitasking operating system provides a better environment for background processes to run. These background programs are not visible to most users.

  • Secured Memory: The multitasking operating systems have well-defined memory management. Due to this, the operating system does not allow any types of permissions for undesirable programs to waste memory.

  • Time Shareable: All tasks are allotted a specified amount of time so that they do not have to wait for the CPU.

Modern multitasking operating systems also provide memory isolation between processes and support different security levels, allowing OS code to do things user code cannot.
