Q. State three merits of placing functionality in a device controller rather than in the kernel and State three disadvantages.
Answer: Three advantages: Bugs are less probable to cause an operating system crash Performance can be improved by utilizing dedicated hardware as well as hard-coded algorithms The kernel is simplified by moving algorithms out of it Three disadvantages: Bugs are harder to fix-a new firmware version or new hardware is essential Improving algorithms likewise require a hardware update rather than just a kernel or device-driver update Embedded algorithms could disagreement with application's use of the device causing decreased performance.
