and application protocols that runs over IP. See IP, ICMP, TCP, UDP, FTP,

them. A network layer must know the current network topology to be able to
route packets to their final destination.

TCP, UDP provides for exchange of datagrams without acknowledgements
or guaranteed delivery.

type and location of documents and resources on an Internet. The syntax is
type://host.domain[:port]/path/filename, where type specifies the type of

an anonymous FTP server; telnet is a connection to a Telnet-based service).
