Study Notes
Operating System Architecture
Monolithic Architecture
- A single, large binary file containing the entire OS
- Advantages:
- Easy to implement and manage
- Fast and efficient
- Disadvantages:
- Difficult to modify and maintain
- Failure of one component can bring down the entire system
Microkernel Architecture
- A small core kernel that provides basic services
- Most OS services are implemented as user-level processes
- Advantages:
- Easier to maintain and modify
- More reliable and fault-tolerant
- Disadvantages:
- Slower due to increased context switching
- More complex to implement
Hybrid Architecture
- Combines elements of monolithic and microkernel architectures
- A small kernel provides basic services, and some OS services are implemented as user-level processes
- Advantages:
- Balances performance and maintainability
- Offers a good compromise between monolithic and microkernel architectures
- Disadvantages:
- Complexity can be high
- May inherit weaknesses from both architectures
Layered Architecture
- The OS is divided into layers, each providing a specific set of services
- Each layer communicates with the layers above and below it
- Advantages:
- Easy to understand and modify
- Easier to add new services and features
- Disadvantages:
- May lead to increased overhead and complexity
- Can be slower due to layer switching
Client-Server Architecture
- The OS is divided into clients and servers, each providing specific services
- Clients request services from servers, which then provide the necessary resources
- Advantages:
- Easy to implement and manage
- Scalable and flexible
- Disadvantages:
- Can be slower due to request-response overhead
- May lead to increased complexity
Virtualization Architecture
- A layer of abstraction between the physical hardware and the OS
- Allows multiple OS instances to run on a single physical machine
- Advantages:
- Improved resource utilization
- Easier to manage and maintain
- Disadvantages:
- May lead to performance overhead
- Can be complex to implement and configure
