(1/5)
1. Why does an operating system manage hardware and software resources?
easy
A. To prevent the computer from turning on
B. To slow down the computer
C. To delete all user files
D. To make the computer easy and safe to use

Solution

  1. Step 1: Understand the role of the OS

    The operating system controls hardware and software to help users operate the computer easily and safely.

  2. Step 2: Eliminate incorrect options

    The options describing preventing the computer from turning on, slowing down the computer, or deleting user files are harmful or incorrect actions, which are not the OS's purpose.

  3. Final Answer:

    To make the computer easy and safe to use -> Option D

  4. Quick Check:

    OS manages resources to help users [OK]
Hint: OS helps users by managing resources safely [OK]
Common Mistakes:
  • Thinking OS slows down the computer
  • Believing OS deletes user files automatically
  • Assuming OS prevents computer startup
2. Which of the following is a correct reason why an OS manages hardware and software?
easy
A. To make the computer run only one program forever
B. To allow multiple programs to run at the same time
C. To stop the user from opening any software
D. To erase the hardware components regularly

Solution

  1. Step 1: Identify the OS function related to multitasking

    The OS manages resources so multiple programs can share the computer fairly and run together.

  2. Step 2: Remove incorrect options

    The options describing running only one program forever, stopping the user from opening software, or erasing hardware components regularly are not functions of the OS.

  3. Final Answer:

    To allow multiple programs to run at the same time -> Option B

  4. Quick Check:

    OS enables multitasking = To allow multiple programs to run at the same time [OK]
Hint: OS lets many programs share resources fairly [OK]
Common Mistakes:
  • Thinking OS runs only one program forever
  • Believing OS blocks all software
  • Assuming OS erases hardware
3. Consider this scenario: Two users try to print documents at the same time. How does the OS manage this hardware resource?
medium
A. It queues the print jobs and sends them one by one to the printer
B. It allows both printers to print simultaneously without any control
C. It shuts down the printer to avoid conflicts
D. It deletes one user's document automatically

Solution

  1. Step 1: Understand OS resource sharing

    The OS manages hardware like printers by organizing access so users don't interfere with each other.

  2. Step 2: Identify correct management method

    The OS queues print jobs to send them one at a time, preventing conflicts.

  3. Final Answer:

    It queues the print jobs and sends them one by one to the printer -> Option A

  4. Quick Check:

    OS queues hardware access = It queues the print jobs and sends them one by one to the printer [OK]
Hint: OS queues shared hardware tasks to avoid conflicts [OK]
Common Mistakes:
  • Assuming OS allows uncontrolled simultaneous printing
  • Thinking OS shuts down hardware to avoid conflicts
  • Believing OS deletes user data automatically
4. A user complains that their program crashes when trying to access hardware directly. What is the likely OS-related cause?
medium
A. The OS blocks direct hardware access to protect the system
B. The OS allows all programs to access hardware freely
C. The hardware is broken and OS cannot fix it
D. The OS deletes the program automatically

Solution

  1. Step 1: Understand OS protection role

    The OS prevents programs from accessing hardware directly to avoid errors and protect the system.

  2. Step 2: Identify cause of crash

    When a program tries direct hardware access, the OS blocks it, causing the crash.

  3. Final Answer:

    The OS blocks direct hardware access to protect the system -> Option A

  4. Quick Check:

    OS protects hardware access = The OS blocks direct hardware access to protect the system [OK]
Hint: OS blocks unsafe hardware access to protect system [OK]
Common Mistakes:
  • Thinking OS allows free hardware access
  • Blaming hardware without checking OS rules
  • Assuming OS deletes crashing programs automatically
5. How does the OS ensure fair sharing of CPU time among multiple running programs?
hard
A. By shutting down programs randomly to reduce load
B. By letting the first program run forever and blocking others
C. By using a scheduler to assign time slices to each program
D. By giving all programs unlimited CPU access simultaneously

Solution

  1. Step 1: Understand CPU sharing concept

    The OS uses a scheduler to divide CPU time fairly among programs, so each gets a turn.

  2. Step 2: Evaluate options for fairness

    Only By using a scheduler to assign time slices to each program describes fair sharing by assigning time slices; others cause unfairness or errors.

  3. Final Answer:

    By using a scheduler to assign time slices to each program -> Option C

  4. Quick Check:

    OS scheduler shares CPU fairly = By using a scheduler to assign time slices to each program [OK]
Hint: OS scheduler divides CPU time fairly among programs [OK]
Common Mistakes:
  • Believing one program runs forever
  • Thinking OS shuts down programs randomly
  • Assuming all programs run simultaneously without control
