The application layer contains protocols that realize user-facing services (HTTP, SMTP, DNS, FTP, SSH). DNS maps human-friendly names to IP addresses via a distributed hierarchical database with caching, TTLs, and iterative/recursive resolution. Application protocols adopt varied transport semantics: HTTP/1.1 and HTTP/2 use persistent connections and multiplexing to reduce overhead; QUIC provides multiplexed streams over UDP with built-in TLS and improved loss recovery and latency.
