An operating System (OS defines how its components are organized and how they interact to manage processes, memory, files, and devices. The simplest form is the Monolithic System, where all functions are combined into one large program. To improve modularity, the Layered Approach divides the OS into levels, each built upon the other. A Microkernel Structure keeps only essential services in the kernel, moving others to user space for flexibility and security. The Module-based approach allows loading and unloading of components dynamically. In the Client-Server Model, services run as servers while applications act as clients, communicating via messages. Virtual Machine Structures provide an abstraction that allows multiple OSs to run on the same hardware. Many modern OSs adopt a Hybrid Structure, blending monolithic speed with microkernel security. Overall, the structure of an OS ensures efficiency, reliability, scalability, and maintainability in system operation.
