| Explanation & Hint:
A multiuser operating system is designed to enable multiple users to access and use the system resources simultaneously and securely. From the options provided, the following are traits of a multiuser operating system:
- Many users can log in simultaneously with a unique account: True. One of the primary features of a multiuser operating system is its ability to support multiple users logging in and working at the same time, each with their own unique user account. This allows for individualized settings, files, and permissions for each user.
- Users can protect their information from other users: True. Multiuser operating systems provide mechanisms such as file permissions and user group management that help users secure their data and protect it from unauthorized access by other users.
- Resources are shared between users: True. In multiuser systems, hardware resources like CPU, memory, and storage, as well as software resources such as applications and network bandwidth, are shared among all users. The operating system manages these resources to ensure that each user gets what they need to perform their tasks, typically through processes like multitasking and time-sharing.
The other statements are not accurate:
- An administrative user gets a dedicated CPU: This is not a typical feature of a multiuser operating system. While administrators may have more privileges or access, they do not generally get dedicated hardware resources such as a CPU in a standard multiuser environment.
- Each user can only log in once per day: This is also not a characteristic of multiuser operating systems. There are generally no intrinsic restrictions on how often a user can log in within a day; such policies would be set by administrative controls rather than being inherent to the operating system itself.
Therefore, the traits that accurately describe a multiuser operating system are that many users can log in simultaneously with a unique account, users can protect their information from other users, and resources are shared between users. |
