Question

which system utility is the most appropriate tool for safely terminating an application that has frozen and is not responding to user input?
the file explorer/finder, by deleting the applications executable file from the program files directory.
the task manager/activity monitor, by selecting the process and choosing the end task or force quit option.
the system settings/control panel, by adjusting the performance priorities to allocate more memory to the stuck program.
the operating systems command prompt, by using a specialized utility program to restart the frozen applications window.

what is the primary function of a file extension (e.g.,.pdf,.jpg,.exe) in the context of operating system file management?
to determine the files exact size and the specific date it was last modified by the user.
to inform the operating system which application should be used to correctly open and display the file.
to encode the files creation metadata, including the authors credentials and system serial number.
to assign a unique security identifier that dictates which user accounts have read/write access permissions.

a student decides to save all documents for all courses directly onto the computers desktop. which principle of file management does this violate?
utilizing system settings to customize display resolution for better visibility of file icons.
best practice for application management, as the desktop is typically reserved for program shortcuts.
best practices for file organization, as it creates clutter, hinders navigation, and increases backup risk

Explanation:

1. For the first question:

• The File Explorer/Finder deleting the executable is not a safe way to terminate a frozen app as it can cause system instability.
• The System Settings/Control Panel adjusting performance priorities won't terminate a frozen app.
• The command prompt restarting the window is not the standard way.
• The Task Manager/Activity Monitor with “End Task” or “Force Quit” is the correct tool for safely terminating a frozen app.

1. For the second question:

• File extensions do not determine file size and modification date.
• They do not encode author credentials and system serial number.
• They do not assign security identifiers.
• Their primary function is to inform the OS which app to use to open the file.

1. For the third question:

• Saving all documents on the Desktop violates file - organization best practices as it causes clutter, hinders navigation, and increases backup risk. Customizing display resolution is not related. And while the desktop is for shortcuts, the main issue is file organization.

Answer:

1. The Task Manager/Activity Monitor, by selecting the process and choosing the 'End Task' or 'Force Quit' option.
2. To inform the operating system which application should be used to correctly open and display the file.
