Question

6 multiple choice 2 points how does an os enhance security and access control? by installing antivirus software by increasing the computers processing speed by managing user permissions and login security by creating backups of all files automatically 7 multiple choice 2 points which of the following best describes a batch operating system? it processes jobs one after the other without user interaction it responds quickly to real - time events the user can interact with the system while it processes jobs it processes multiple tasks simultaneously using more than one cpu 8 multiple choice 2 points in what scenario would a real - time operating system be the best choice? for processing jobs in large batches for controlling airplane systems that require immediate responses for running multiple programs on a smartphone for managing tasks on a home computer

Explanation:

• Question 6:
• Antivirus software is a separate application, not part of the OS's core security and access control.
• Increasing processing speed is related to hardware and performance, not security.
• Creating backups is a data - protection feature, not directly security and access control.
• OS manages user permissions (who can access what resources) and login security (authentication), which are key aspects of security and access control.
• Question 7:
• A batch operating system processes jobs one after another without user interaction.
• Responding quickly to real - time events is a characteristic of real - time operating systems.
• User interaction during job processing is more common in interactive or multi - user systems, not batch.
• Processing multiple tasks simultaneously with multiple CPUs is related to multi - processing systems, not batch.
• Question 8:
• Processing jobs in large batches is for batch operating systems.
• Running multiple programs on a smartphone is more about general multitasking (like in a mobile OS, not necessarily real - time).
• Managing tasks on a home computer is for general - purpose operating systems.
• Real - time operating systems are designed for scenarios like controlling airplane systems that require immediate responses.

Answer:

• Question 6: By managing user permissions and login security
• Question 7: It processes jobs one after the other without user interaction
• Question 8: For controlling airplane systems that require immediate responses
