Front 3

UDP

Back 3

User Datagram Protocol
User Datagram Protocol-Transport Layer
-Core member of the IP Suite
-Used to send messages, referred to as Datagram to other hosts on an IP network without prior communications to set up special transmission channels or data paths

Front 4

TCP/IP Suite

Back 4

Networking model and set of communication protocols used for the internet and simliar networks.

Provides end to end connectivity specifying how data should be formatted , addressed , transmitted , routed and received at the destination.

Organized into 4 Layers
-Link Layer
-Internet Layer
-Transport Layer
-Application Layer
