Internet Architecture and Protocolsform the backbone of how the global internet operates, defining both its structural design and the rules for communication between devices. The architecture is built on a layered model, most notably the TCP/IP framework, which organizes functions into layers such as the application, transport, internet, and network access. Each layer has specific responsibilities, from handling physical data transmission to managing logical addressing and ensuring reliable delivery. Protocols like HTTP, FTP, SMTP, and DNSgovern everyday services such as web browsing, file transfers, email, and domain name resolution. Together, this architecture and its protocols ensure interoperability, scalability, and resilience, allowing billions of devices worldwide to communicate seamlessly across diverse networks.
