ARCHITECTURE OF AN OPERATING SYSTEM

Architecture is the fundamental of an operating system that defines the interconnection between the system components. An operating system can have different architectures:

1.     Monolithic architecture

2.    Layerd archtecture.

3.     Virtual machine architecture

4.     Exokernel architecture

5.    Client server architecture 

6.     Micro kernel architecture

Monolithic Architecture

Monolith means composed all in one piece. The Monolithic application describes a single-tiered software application in which different components combined into a single program from a single platform. Components can be:

• Authorization — responsible for authorizing a user
• Presentation — responsible for handling HTTP requests and responding with either HTML or JSON/XML (for web services APIs).
• Business logic — the application’s business logic.
• Database layer — data access objects responsible for accessing the database.
• Application integration — integration with other services (e.g. via messaging or REST API). Or integration with any other Data sources.
• Notification module — responsible for sending email notifications whenever needed.
