16 What is present at each Layer?

17 How to remember OSI Layers?

18 Internet protocol stack
application: supporting network applications FTP, SMTP, HTTP transport: process-process data transfer TCP, UDP network: routing of datagrams from source to destination IP, routing protocols link: data transfer between neighboring network elements Ethernet, i (WiFi), PPP physical: bits “on the wire” application transport network link physical Introduction
