Traffic moves over the Internet through a series of connections: a PDA connects to a POP, which connects to an ISP router, which routes data between networks. POPs allow users to connect to the Internet and remotely access servers. ISPs connect customers through various connection lines and provide additional services like data storage and original content. Routers relay data flowing on networks to other networks, with multi-protocol routers supporting multiple protocols.
