An operating systemthat enables more than one user to access the same data is called

A multi-user operating system is one that allows multiple users to access the same data at the same time. This type of OS enables different users to log into the system and access files, folders, and programs that are shared across the network. Each user can have their own account with individual permissions, which controls what they can and can't access. For example, in a multi-user operating system, a user can save a file on a shared folder, and other users can access and modify that file if they have permission. This allows multiple users to collaborate and work together on the same documents, databases, or projects. In contrast, a single-user operating system only allows one user to access the data at a time, while a multi-tasking operating system allows one user to run multiple programs simultaneously. Virtual memory is a technology that allows the computer to use a portion of the hard drive as additional RAM, enabling the computer to run more programs than it could with physical RAM alone.
