> [!Info] > This page is currently a work in progress. - Just like [[TCP]], operates at the **Transport Layer (Layer 4)** of the OSI model and provides end-to-end communication between applications. - No handshake or ack. - Because no 3 way handshake or order validation, is faster/lower latency. - Used for services that require fast or low latency connections. - Faster but less reliable than TCP. - Examples: - Video streaming, gaming, [[DNS]] lookups, DHCP.
