The data is first stored in main memory and later transferred to the peripheralby DMA.
The write operation directly updates the peripheral’s hardware registermapped at that address.
The CPU triggers an interrupt to notify the peripheral of new data.
The value is cached and updated only after multiple writes.

Both user space and kernel space run with limited privileges
User space applications run with limited privileges and must use syscalls toaccess resources, while kernel space has full access to hardware and drivers
Kernel space is only used for storing user applications, while user spacehandles drivers
