What does it mean when a system is referred to as "multi-tasking"?

When a system is referred to as "multi-tasking," it means that it can perform multiple tasks simultaneously. This capability allows the operating system to manage the execution of various applications at the same time, providing the user with the ability to switch between them without having to close any. In a multi-tasking environment, the system allocates processor time to each task, enabling users to run applications like web browsers, word processors, and media players concurrently.

For instance, a user could be editing a document while also listening to music and browsing the internet all in real-time, demonstrating the seamless integration of various functions. This makes for a more efficient and productive user experience, as multiple processes can be handled without interrupting one another. Multi-tasking is a fundamental feature of modern operating systems, enhancing both usability and functionality.
