Question

question 4 (1 point)
what is the purpose of the ps command in linux?
to display a snapshot of current processes
to terminate processes
to prioritize cpu allocation
to manage memory usage
question 5 (1 point)
in linux, what is the difference between foreground and background processes?
foreground processes run without user interaction
foreground processes interact with the user, while background processes run without user interface
background processes are automatically terminated
foreground processes consume less memory
question 6 (1 point)
in process scheduling, what does a time slice refer to?
the total time a process can run
the time it takes to load a process into memory
the allocated amount of cpu time given to a process before it is preempted
the time it takes to terminate a process

Explanation:

• Question 4: The ps (process status) command in Linux is used to display information about currently running processes. It shows a snapshot of the processes, including details like process ID, user, CPU usage, etc.
• Question 5: Foreground processes interact with the user (e.g., a text editor where you type commands). Background processes run without user interaction (e.g., a service running in the background).
• Question 6: In process scheduling, a time slice is the allocated amount of CPU time given to a process before it is preempted (i.e., another process gets a turn to use the CPU).

Answer:

• Question 4: To display a snapshot of current processes
• Question 5: Foreground processes interact with the user, while background processes run without user interface
• Question 6: The allocated amount of CPU time given to a process before it is preempted
