What does 'Multi-user Login' mean?

Multi-user Login is a feature of multi-user software, which allows several people to access the same computer at the same time. Multi-user systems are time-sharing systems. To prevent leaving the CPU idle while waiting for I/O operations to complete, most batch processing systems for mainframe computers are "multi-user." In this context, though, "multitasking" is more commonly used. An example is a Unix or Unix-like system where numerous distant users have simultaneous access to the Unix shell prompt (through a serial port or Secure Shell). Another example of a thin client is utilizing several X Window sessions spread across multiple terminals powered by a single system.
