Kernel & System Calls
Describe the typical sequence of steps (3-4 steps) when a user program executes a System Call (e.g., read()). Detail the role of the Trap Instruction.
Explain the role of a Device Driver in the OS structure. Describe how it acts as an interface layer between the kernel and the hardware, using a disk drive as an example.
Describe the role of the Device Status Register (DSR) in I/O operations. Explain how the OS uses polling to check the DSR when waiting for an I/O completion.
Distinguish between Policy and Mechanism in OS design (e.g., scheduling). Give an example of each in the context of memory management (e.g., when to swap vs. how to swap).
Compare the architectural differences between a Monolithic Kernel and a Microkernel. State one advantage and one disadvantage for each structure concerning stability and extension.
Explain the need for User Mode and Kernel Mode operation. Specify which mode the operating system runs in and which instructions (e.g., I/O) are considered privileged.
Explain the purpose and advantage of using Loadable Kernel Modules (LKMs). How does this technique contribute to the flexibility and maintainability of a modern monolithic kernel?
Reiterate the importance of Dual-Mode Operation (Kernel/User) for system integrity. Provide an example of how the OS uses this to protect its own data structures from user processes.
Describe the sequence of actions the OS takes when an Interrupt occurs (e.g., I/O device completion). Detail the role of the Interrupt Vector.
Describe the basic sequence of steps (3-4 steps) that an OS follows during the Bootstrapping process, starting from when the computer is powered on (e.g., BIOS, Boot Loader).
List and describe 3 different methods used to pass parameters from a user program to the OS kernel during a system call (e.g., registers, stack).
Describe the role of the Device-Status Table maintained by the OS. Explain how this table helps the OS manage multiple I/O operations simultaneously.
Define a Hybrid Kernel architecture (e.g., Windows NT, macOS). Explain how it attempts to combine the performance of the monolithic approach with the modularity of the microkernel.
