Once the TCP handshake completes, data begins to flow between machines. This article breaks down how that data moves across the network using the TCP protocol. Packet flow is handled by two protocols: TCP and UDP. This article covers TCP; UDP will be covered next. Prerequisites: Familiarity with the TCP/IP transport layer and basic socket […]
