25. ComSys - Operating System Quiz

What is multitasking in the context of operating systems?

• Running applications with limited memory

• Running multiple applications at the same time

• Running one application at a time

• Running applications in a sequence

How does the processor give the illusion of simultaneous execution of multiple programs?

• By allocating more memory to each process

• By increasing the speed of the processor

• By running all programs at the same time

• By allocating a small time slice to each process

What happens to the memory locations when a program is closed?

• They are locked and cannot be used again

• They are erased from the memory

• They are shifted around to accommodate new programs

• They are marked as free and available for reuse

How does the operating system manage fragmented memory?

• By allocating more memory to each program

• By keeping track of different program fragments

• By erasing the fragmented memory

• By limiting the number of programs that can run simultaneously

What is the purpose of a device driver in an operating system?

• To manage the memory allocation for different programs

• To monitor the performance of the processor

• To control the multitasking capabilities of the processor

• To translate operating system instructions into commands that hardware understands

Which technology does an inkjet printer use to produce output?

• Dropping droplets of ink onto the page

• Magnetizing particles onto the page

• Fusing toner to the page

• Using a pen to draw across the page

What does the clock in the corner of the screen represent in multitasking?

• The actual time at which the programs are running

• A maintenance task performed by the operating system

• The time allocated to each program by the processor

• The time taken by each program to execute

How does the operating system enable data sharing between multiple programs?

• By allowing copy and paste functionality

• By increasing the memory allocation for each program

• By limiting the number of programs that can be open at the same time

• By running all programs simultaneously

What is the purpose of virtual memory in memory management?

• To eliminate the need for memory management

• To compensate for the shortage of physical memory

• To increase the speed of program execution

• To reduce the number of programs running simultaneously

Why does each peripheral device need its own device driver?

• To control the multitasking capabilities of the peripheral device

• To limit the access of the peripheral device to the memory

• To increase the speed of the peripheral device

• To translate operating system instructions into commands that the hardware understands
