What is virtual memory?
A memory management technique that uses secondary storage when RAM is full.
300
What is a Round robin?
Round robin (RR) is a preemptive scheduling algorithm designed to provide fair time-sharing among processes.
400
What is the role of the Memory Address Register (MAR)?
It stores the address of the memory location currently being accessed.
400
Explain why cache memory is smaller in size compared to RAM
Because cache memory is made using faster and more expensive technology and is designed only to store frequently used data close to the CPU.

What is an interrupt?
A signal that temporarily stops the CPU’s current task to handle an urgent event
400
Why is cache memory placed close to the CPU?
To reduce access time and improve performance
500
Explain one difference between the CPU and the GPU.
The CPU is designed for general-purpose, sequential tasks, while the GPU is optimized for parallel processing of large data sets.
