Question

What is the multi-user Operating system?

Answer 1

Multi-user software is software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete. However, the term "multitasking" is more common in this context.

An example is a Unix server where multiple remote users have access (such as via a serial port or Secure Shell) to the Unix shell prompt at the same time. Another example uses multiple X Window sessions spread across multiple terminals powered by a single machine - this is an example of the use of thin client. Similar functions were also availabe under MP/M, Concurrent DOS, Multiuser DOS and FlexOS

Answer 2

Multi user operating system is a type of Operating system that can manage the different computer systems at once.

Operating system is a system software that manages the software resources, Hardware devices and provides the common application services for computer system. Operating system installs the connection between Humans and Computers. Because of operating system only, we can perform work and give instructions to the computer.

In short, Operating system is a system software that creates the interface between computer and user. Operating system helps us to communicate with computers without knowing their language. It is not easy to use a computer system, mobile, TV any digital device without having operating system in it.

Operating system provides common services to computer system like File search, Calculator, Various in built apps, Word, PowerPoint and excel etc. Due to which, it becomes easy to use a computer system. If we use a computer system without OS, then we will just seeing Binary codes on our screen. Which aren't easy to get understood.

What is 32 Bit and 64 Bit ?

32 Bits system can handle ram only 3.2 GB of ram. 32 Bits system processes the data simultaneously and output in given in seconds. This systems required 32 bit CPU and OS.

64 Bits systems can handle ram up to 17 Billion GB. This systems processes the data in the bit of second. This are very simultaneous systems. This systems 64 bit CPU and OS.
