Other operating systems do not have all of the concurrent mechanisms that Linux has.
Concurrency is a term used in software engineering to describe techniques and processes that enable a computer to do many tasks at once or at least seem to do so.
To do this, new hardware and software features were necessary.
Linux handles real-time signals and integrates all prior UNIX concurrency mechanisms.
An operating system (OS) is a piece of software that manages the hardware and software resources of a computer while also offering standard functionality to other programmes.
Time-sharing operating systems may include accounting software to measure the cost of processing time, storage, printing, and other resources.
