Time sharing in operating systems allows multiple users to interact with a computer simultaneously by allocating a small time slice for each user’s process. This approach ensures responsiveness and efficient CPU utilization by quickly switching between tasks, giving the illusion of parallelism. Essential properties include process scheduling, where the OS manages the order and duration of execution; context switching, which saves and restores the state of processes; and user interactivity, enabling real-time user engagement with applications. Overall, time sharing enhances system efficiency and user experience by maximizing resource utilization.
Running of the jobs in an orderly way is known as batch system OS. On the other hand, tasks are allotted specific OS switches and time in time sharing OS.
The system must process data immediately, and cannot wait like a batch OS would
A hard real-time system guarantees that critical tasks complete on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the operating system to finish any request made of it. A soft real time system where a critical real-time task gets priority over other tasks and retains that priority until it completes. As in hard real time systems kernel delays need to be bounded
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
No.. The time sharing systems mostly do not have long term schedulers.This is because in these systems, the new processes are directly put in the ready queue itself.If the no of process becomes very large then MTS is invoked.
TSOS stands for Time Sharing Operating System; it was an operating system for RCA (Radio Corporation of America) mainframes of the RCA Spectra 70 series.RCA was in the computer business until 1971. Then it was sold to Sperry Corporation; Sperry offered TSOS renaming it to VS/9. In the mid seventies, an enhanced version of TSOS was offered by the German company Siemens and was called BS2000 here.While Sperry (respectively Univac after the company was renamed) discontinued VS/9 in the early 80's, BS2000, now called BS2000/OSD is still offered by Fujitsu Siemens Computers and used on their mainframe customers primarily in Europe.TSOS was the first operating system that supported virtual addressing of the main storage. Beyond that it provided a unique user interface for both, time sharing and batch which was a big advantage over IBM's OS/360 or their successors MVS, OS/390 and z/OS as it simplified the operation.
The name of the computer can be changed in the Mac OS X System Preferences' Sharing section.

The BIOS. The BIOS provides services to the OS and the OS provides services to the applications.
Operating System (OS) Software
Normally there is only one OS installed at a time.
right click then click properties then i dont know
