What are advantages and disadvantages of a layered architecture? - Separation of concerns among logical layers promotes flexibility, scalibility, and maintainability. Multiple applications can reuse the components. It enables teams to work on different parts with minimal dependencies on other teams What are the similarities of the OSI model and five-layered Internet model? - They are both based on layered architecture. The are comparable to each other - see image 1 Both are networking stand...

Network A chain of communication that connects places. NOT THE INTERNET. Your home is its own ____ Hub Dumb, doesn't think, sits at physical layer of OSI model, Connects router to the network, sends data packets to ALL connected devices. Switch Used to connect devices in a specific networks, Builds a MAC address tables and sends accordingly. Is a more complex version of a Hub. Forwards data packets. Sits at Data Link Layer of the OSI model. Router is a point of connection between two or ...

What are advantages and disadvantages of a layered architecture? - Each protocol layer offers different services. Some advantages are scalability, flexibility, and ease of adding / removing components making it easier for cost-effective implementations. Disadvantages include: some layers functionality depends on the information from the other layer and violates the goal of layer separation; one layer may duplicate lower layer functionalities; overhead both in computation and in message ...
