An operating system for a computer that allows several users to communicate simultaneously across the network is known as a system with multiple users (OS). With an operating system built for multiple users, numerous people can use a single computer or network at the same time. Each user will have their own account and be able to perform their own tasks.
When several users need to share the same materials or information and collaboration and interaction are crucial, multi-user methods of operation are commonly used. These kinds of systems are useful in settings where numerous users need access to comparable machines or networks, including offices and educational institutions.

What is Multi-User Operating System?
When multiple users may access a single system running a single operating system, the system is said to be multi-user. These systems often have a great deal of complexity to them, and they have to handle the demands of the different users that are linked to them. Typically, users will be seated at terminals or PCs that are networked to the system, along with additional system devices like printers. The way that multiple users access the same operating system from separate workstations distinguishes multi-user operating systems from connected single-user operating systems.
Creating an operating system with multiple users is primarily intended to be used for batch processing and time-sharing on mainframe computers. Large businesses, the public sector, academic institutions like large universities, and servers running Windows or Ubuntu now frequently use this multi-user operating system. Multiple users can access the hardware, kernel, and operating system simultaneously on these systems.
Typically, its duties include managing memory and processing for other programs that are already executing, recognizing and utilizing system hardware, and effectively managing user interactions and data requests. Because multiple users depend on the operating system to function correctly at the same time, it's especially crucial for multi-user operating systems.

Components of the multi-user operating system:
Memory is made up of RAM, or main memory. Since main memory limits the number of applications that may run at once, it is considered a crucial component of the operating system. Every program that is run needs to have its physical storage replicated since the system has the ability to correct data that is stored in main memory.The several kinds of tangible storage
- Disc: A hard disk's capacity to store enormous amounts of data also dictates how many programs may run simultaneously.
- Disk floppy: Though it costs less, it is still drinkable.
- Disks with optics: They read and write data using a laser. They are portable and have a huge data capacity.
- Tapes: Though pricey, they have a massive data capacity Kernel Located in the primary memory of the computer system, this part may communicate with the hardware directly. Because it is built in a low-level language, the multi-user operating system uses the kernel component at a low level.
- Processor: The central processing unit (CPU) is the name of the computer's central processing unit.
- Device handler: Fulfilling every request from the whole device request queue is the device handler's main objective. In order to function in continuous cycle mode, the device handler first removes the I/O request block from the queue side. The handler is based on the idea of a queue with the first in, first out (FIFO) rule.
- Spooler: On-line peripheral output simultaneously. All computer activities are executed by the spooler, which also simultaneously produces the results.
- Interface user: Provide an easy-to-use environment for everyone utilizing the computer system. It serves as the interface for users and hardware or software. One of the systems that uses the multi-user programming approach is the mainframe. To keep information about transactions and bank accounts, banks utilize it extensively. This mainframe offers several benefits, including scalability and security.
Types of Multi-user Operating Systems:
The following categories comprise multi-user operating systems:
The distributed operating system functions as a network that facilitates communication and operation between end users. A distributed operating system, which is often referred to as distributed computing, is made up of several different parts. The components are spread across several computers so that the user can communicate and work together as a cohesive unit.

This system allots a brief amount of CPU time to each user task. Each time slice that is created from the CPU time is too small for the user. Time slicing is the term for this CPU time division technique. Round Robin Scheduling is another name for the scheduling algorithm known as time slicing. It ensures that every process in the system has an equal chance to use CPU time.
A partial analysis of the time-sliced system is the mainframe.
Systems with many processors used simultaneously are referred to as multiprocessor systems. Because many processors operate side by side, using multiple processors improves system performance. It operates more quickly than the operating system with a single processor. If one processing in a multiprocessor system fails, the other processor finishes the tasks it was given.
Examples:
An operating system designed for multiple users can share a number of devices, including hard drives, plotters, fax machines, and printers. This feature allows users to share their own documents. Under this arrangement, a tiny amount of CPU time is allotted to each user.
Operating systems with multiple users have the capability to perform many jobs and multiple programs concurrently.
The phrase "background processing" describes the execution of commands "in the background," as opposed to processing them. Real-time communication between the system and other programs is typical.
A technique by which multi-user operating systems can handle multiple user requests simultaneously by rapidly switching between jobs.
The operating system is responsible for managing the hardware and software resources of a computer.
The multi-user operating system conceals a number of its features from users. It is caused by things like the OS being intuitive or things like disk formatting that occur at the bottom end.
Multi-user operating systems include Linux, Mac OS X, Windows 1010, Unix, and Ubuntu, among others.
An operating system (OS) for computers that enables numerous users to access a single system running a single OS on separate computers or terminals is known as a multi-user OS. Multi-user operating systems include Windows 1010, Mac OS X, Linux, Ubuntu, and Unix.
What kinds of features are offered by operating systems for single and many users?
An operating system that allows only one user to access the computer at once is known as a single-user operating system. An operating system that permits multiple users to access a computer at once is known as a multi-user operating system. All of the CPU's resources are loaded into a single superuser's profile by the bootloader.
What is the function of a multiuser?
Numerous users can share a single computer system's resources thanks to multiuser operating systems. The cost per user of accessing pricey resources is decreased through sharing. It allows users to collaborate in an office setting, for example, by working from a shared database of data. It is possible for users to message one another.
Where is multi-user used?
Computer software that permits several users to access a computer is known as multi-user software. Systems for sharing time can have several users. In order to prevent the CPU from being idle while it waits for I/O operations to finish, the majority of batch processing systems for mainframe computers may also be referred to as "multi-user."

How to work the Multi-User operating system?
The multi-user system contains the single master system. Every network user has the ability to open their local copy of the system and access the master system at any time and from any location. Another term for the local version is a "functioning model." On their local working model, any user can make changes, remove files, and add new ones; however, until this model is saved to the master system, no other users will be able to access it.
Advantages of the Multi-user Operating System
- Prevents Disruption: Multiple computers and gadgets running on the same network are part of a multi-user operating system. As a result, the harm done to one network computer does not affect the others. That way, it prevents interruption, which is the main benefit of an operating system with multiple users.
- Resource Distribution: A person can make the file they are working on visible to other users by sharing it. As a result, the file is always accessible to any user that needs it. For instance, the person working on the file can share it with other users so that they can examine it if they would like to.
- Used in Buses, Trains, and Airlines: The ticket reservation system makes use of a multi-user operating system that allows several users to log in at once, book and cancel tickets, and verify the availability and status of tickets that have been booked.
- Data backup: Since data backups are completed on the user's machine, the multi-user operating system facilitates data backups.
- Server stability: Servers from all over the world in all time zones can be accessed remotely thanks to the multi-user operating system. The server is methodical and stable since the newest technologies have been incorporated into the hardware and software upgrades.
