Understanding CPU Scheduling and Multitasking

What is the primary function of CPU scheduling?

• To increase the speed of the CPU

• To manage the memory allocation

• To decide the order of thread processing

• To enhance the graphics performance

How does the operating system determine which thread gets processed first?

• By the size of the thread

• By the age of the thread

• By the priority value assigned to the thread

• By the color of the thread

What does QoS stand for in the context of CPU scheduling?

• Quality of Service

• Quantity of Speed

• Quick Operating System

• Quantum of Space

What is the main advantage of using libraries in multi-threading?

• They increase the CPU speed

• They reduce the need for extra coding by developers

• They improve the sound quality

• They enhance the graphics quality

What is context switching in CPU scheduling?

• Increasing the CPU clock speed

• Moving a thread from one core to another

• Enhancing the graphics performance

• Decreasing the CPU temperature

Why are e-cores included in desktop CPUs?

• To allow more cores to be packed onto a chip

• To improve battery life

• To increase the CPU clock speed

• To enhance the graphics performance

How do hybrid chips like Intel's Alder Lake improve performance?

• By enhancing the graphics performance

• By using only high-performance cores

• By combining high-performance and power-saving cores

• By increasing the CPU clock speed

What is the role of hardware assist features in newer CPUs?

• To increase the CPU clock speed

• To enhance the graphics performance

• To manage the memory allocation

• To provide advice to Windows on scheduling decisions

What is the default behavior of the Windows scheduler regarding p-cores and e-cores?

• It uses e-cores first

• It uses p-cores first

• It uses both equally

• It does not use either

What is the main benefit of a multi-core model in CPUs?

• It can legitimately multitask

• It can enhance the graphics performance

• It can increase the CPU clock speed

• It can manage the memory allocation
