A microkernel is an OS architecture where only essential functions (like process management, memory management, and inter-process communication) run in kernel mode.
Other services (like device drivers, file systems, etc.) run in user mode.
Advantage: More stable and secure; easier to maintain.
Disadvantage: Can be slower due to more user-kernel interactions.
Strategies used to safeguard data from loss or corruption.
Types:
Kerberos is a network authentication protocol that allows systems and users to prove their identity to each other before accessing resources, ensuring secure communication within a network. It's a trusted third-party system that verifies user identities without sending passwords directly across the network.

m1) explain in detail about CPSR? The Current Program Status Register (CPSR) is a 32-bit special-purpose register in ARM processors. It plays a central role in controlling the state and execution flow of the processor.
###CPSR structure : CPSR has four 8-bit fields: Flags (holds condition flags), Status and Extension (reserved), and Control .Only the Control and Flags fields are used in current ARM designs.
###Key Bits in CPSR: * N (31) – Negative flag * Z (30) – Zero flag * C (29) – Carry flag
