Why Layered Architecture is Required in Computer Network?

Answer: Layered architecture in computer networks ensures modular design, abstraction, interoperability, troubleshooting ease, and scalability. Layered architecture helps to divide the unmanageable and complex task into smaller sub parts and then solve it efficiently.

By dividing complex processes into more manageable components, a layered architectue facilitates modularity and scalability in system design. Distinct layers with well-defined interfaces enable seamless integration and substitution of functionalities,and promoting flexibility. Modifications within one layer can be made without disrupting others, allowing for gradual improvements over time.

Additionally, individual testing of layers streamlines debugging and troubleshooting processes, ensuring efficient performance. In essence, layered architecture provides a structured framework for building resilient and adaptable computer networks, making it an essential aspect of modern network system design and deployment.
