TCP vs UDP
Comparing strict, handshake-established byte streams against fast, lightweight fire-and-forget datagram delivery.

TL;DR
Comparing strict, handshake-established byte streams against fast, lightweight fire-and-forget datagram delivery.
Concept Overview
TCP (Transmission Control Protocol) vs. UDP (User Datagram Protocol) represents the choice of network transport protocol. TCP guarantees perfect, ordered packet delivery via handshakes, while UDP offers ultra-fast, fire-and-forget datagram routing without tracking.
Key Architectural Pillars
TCP
Connection-oriented transport protocol featuring 3-way handshake, error-checking, flow-control, and guaranteed ordered delivery.
UDP
Connectionless transport protocol offering fast datagram transmission without connections, ordered queues, or delivery tracking.
