• Defragmentation software

• Compression software

• Word processor

What is the role of the operating system in relation to application software?

• To manage the data acquired by the programs

• All of the above

• To load the programs into memory

• To provide a user interface experience

What is an important part of an operating system in terms of memory?

• Memory management

• Memory defragmentation

• Memory encryption

What is the purpose of handling interrupts in an operating system?

• To handle requests for the processor's attention

• To interact with peripheral hardware

• To manage the computer's memory

• To prevent data loss when the power is switched off

What is multitasking in the context of operating systems?

• Seeming that multiple programs are running in parallel

• Seeming that multiple programs are running sequentially
