Nope it would be single user operating system because at any time it would be providing service to a single user. It doesn't matter that the current user is different from the last user as it is essentially serving one user at a time. Multiuser operating systems allocates system resources to multiple concurrent users with memory protection mechanism using paging or segmentation. Views Â· View Upvotes.
A multi-user system, by definition, supports concurrent processing of multiple tasks (once known as time-sharing) or true parallel processing if it has multiple CPUs. While batch processing systems often ran jobs for serveral users concurrently, the term multi-user typically implies interactive access. Before Ethernet networks were commonplace, multi-user systems were accessed from a terminal (e.g. a vt100) connected via a serial line (typically RS-232). This arrangement was eventually superseded by networked personal computers, perhaps sharing files on a file server.
