IBDP Computer Science: Resource Management

What is a key function of the operating system regarding resource management?

• Managing social media accounts
• Managing the computer's resources, like memory and processing power
• Managing internet connectivity only
• Managing file deletion protocols

Which resource is directly managed by the operating system to improve the system's performance?

• Cloud storage

• The processor

• External USB devices
• User passwords

Virtual memory is used by an operating system to:

• Expand working memory onto a hard disk

• Store user preferences
• Run virtual reality

• Manage user accounts

Multitasking in an operating system allows for:

• Running a single program at a time
• Sequential execution of multiple processes
• Apparent simultaneous execution of multiple processes

• Tasking multiple systems

In the context of operating systems, what does 'paging' refer to?

• Deleting blocks from RAM

• A technique for memory management, involving fixed size blocks

• A technique for memory management, involving logically sized blocks

• A scheduling policy for processes

The primary purpose of scheduling policies in an operating system is to:

• Encrypt user data
• Allocate CPU time to processes
• Give all tasks equal processing time

• Manage network traffic

Interrupts in an operating system allow the CPU to:

• Ignore peripheral device requests
• Respond to asynchronous events from hardware devices
• Periodically check system requirements

• Focus on a single task at a time

Peripheral management by an operating system involves:

• Blacklisting and whitelisting peripheral devices

• Managing external devices connected to the computer
• Controlling cloud storage services
• Managing the deletion of files

An operating system hides the complexity of hardware from users and applications through:

• Data encryption
• Hardware abstraction
• Internet filtering
• User interface customization

The term 'resource limitation' in the context of computer systems most often refers to limitations in:

• User knowledge
• Software availability
• Hardware capabilities
• Internet connectivity
