Examples of popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. So-called mobile operating systems include Android and IOS. A single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency. Disadvantages Single User Single Multi Task Operating System. (Examples of Single User Operating System) Windows; Linux; Mac O/S; MS-DOS; Palm OS; Read More -: मल्टीयूज़र ऑपरेटिंग सिस्टम (Multi User Operating System in Hindi) Conclusion . Multi-User. A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources. For example - the data to be processed and stored on disk, the system permits multiple users to interact with the system at the same time. A real-time operating system may be single-tasking or multi It can be termed as single-user or multi-user OS, and single-tasking or multi-tasking OS.A multi-user system must be multi-tasking. MS-DOS and Windows 3x are examples of single user operating system. Whereas UNIX is an example of multi-user and multitasking operating system. Multi-user operating system is a computer operating system (OS) that allows multiple users to access a single system with one OS on it.It refers to more than one person can be able to log into the computer.Each person will have their own settings. MultiTasking Operating System refers to the ability of a computer to perform more than one task or A DBMS is a single-user if at most one user at a time can use the system. A DBMS is a multi-user if many/multi-users can use the system and hence access the database concurrently. Single-User DBMSs are mostly restricted to personal computer systems. Most DBMSs are multi-user, like databases of airline reservation systems, banking databases, etc. A single-user, single-task operating system, like MS-DOS, with basic kernel functions that are non-reentrant: only one program at a time can use them. 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 Ali's new computer uses a single-user, multi-tasking operating system. Ali wants to know which utility programs he will need to keep his computer secure and running smoothly. Discuss the utility programs Ali will need, justifying why he needs them. The quality of written communication will be assessed in your answer to this question. Multi-tasking refers to the operating system's ability to execute two or more tasks of a single user concurrently. Most of the operating systems used in micro computers were single-user operating systems. These operating systems allow the user to work on one task at a time. For example, in many single-user operating systems, a word-processing Single User - Single Task. These operating systems are designed to support a single user and allow the execution of only one task at a time. Examples include early versions of MS-DOS. Single User - Multi-Task. Single user - multi-tasking operating systems enable a single user to run multiple applications simultaneously. AMTHIL.
