Internet Architecture refers to the design and structure of the Internet, which enables communication between devices worldwide. It consists of various layers, including the application layer, where user-facing services like web browsers operate, and the transport layer, which ensures data is sent and received reliably. At the core of Internet Architecture are protocols, such as TCP/IP, that dictate how data is transmitted. This architecture also includes routers and servers that manage data traffic, ensuring efficient delivery. Overall, Internet Architecture is essential for the seamless functioning of online services and connectivity.
