What is Irql level?

An Interrupt Request Level (IRQL) is a hardware-independent means with which Windows prioritizes interrupts that come from the system’s processors. On processor architectures on which Windows runs, hardware generates signals that are sent to an interrupt controller.

Can you put a 4gb and 8gb RAM together?

“You Can’t Mix RAM Sizes,” or “You Can’t Mix RAM Brands” Most laptops or computers come with at least two slots for RAM sticks, if not more. Most modern motherboards will provide four RAM slots. There’s a prevailing misconception you cannot use different RAM sizes together or that you cannot mix RAM brands.

How does RAM get damaged?

The RAM module can be damaged if its removed while the computer powered up or if its removed while the motherboard still has a residual charge after its been powered off. RAM modules can also be damaged by static discharge if a user touches it and they are not grounded.

How can the CPU recognize the device requesting an interrupt?

Vectored Interrupts: In vectored interrupts, a device requesting an interrupt identifies itself directly by sending a special code to the processor over the bus. This enables the processor to identify the device that generated the interrupt.

Is 12 GB RAM possible?

Yes … It is Possible to have 12 GB RAM .. You can basically use 1x8GB + 1x4GB Ram cards for a dual configuration or use 3x4GB Ram cards for triple configuration…But its Kinda inefficient.. Pc Ram works efficiently when pared with the same RAM cards and either dual configuration or quad configuration…
