Isaac and Omar are discussing computer systems. Isaac asks, 'What is the purpose of virtual memory?'

• To increase the speed of the CPU

• To store frequently used data

• To swap pages between main memory and virtual memory when needed

• To store backup data

During a computer science class, Andrei noticed his computer was slowing down significantly. What is disk thrashing?

• When the CPU overheats

• When a computer has to swap pages back and forth too often, causing the computer to slow down

• When the hard drive fails

• When the RAM is full

During a group project, Andrei and Emad are working on a computer. Suddenly, the computer receives a signal that requires immediate attention. What is this signal called?

• A signal sent to a CPU to signify another process is in need of processing time

• A command to start a new programme

• A method to increase memory

• A way to shut down the computer

During a computer science class, Andrei asked, 'What is the purpose of an interrupt service routine (ISR)?'

• To increase the speed of the CPU

• To handle the situation that has triggered the interrupt

• To store data temporarily

• To shut down the computer
