Computer Networks A Systems Approach and Top down approach what is the difference

The main difference between the systems approach and top-down approach in computer networking is the perspective from which the network is viewed and analyzed.

The systems approach focuses on the individual components that make up the network, such as the hardware, software, and protocols. It seeks to understand how these components work together to create a functional network and how they can be improved for better performance.

On the other hand, the top-down approach takes a more holistic view of the network, starting from the end-user perspective and working backwards. It focuses on the overall design of the network, including its purpose, goals, and functionality, before delving into the individual components.

In summary, the systems approach is more bottom-up and technical, while the top-down approach is more strategic and user-focused. Both approaches are important for understanding and improving computer networks.
