TCP/IP is the standard default.
HTTP - or "Hyper Text Transfer Protocol".
HDLC (High-Level Data Link Control) is a bit-oriented synchronous data link layer protocol cHDLC (Cisco HDLC) was created by cisco to address the HDLC protocol's inability to provide multi-protocol support. Thus, cHDLC frames contain a field for identifying the network protocol being encapsulated. Ethernet networks are packet based and have no concept of a connection or circuit and also lack basic security features By using PPPoE (encapsulation), users can "dial" from one machine to another over an Ethernet network, establish a point to point connection between them and then securely transport data packets over the connection. Answer: security
SMTP uses port number 465 by default. It stands for Simple Mail Transfer Protocol. It is the protocol for sending emails in a network.
Kerberos.
Kerberos is the default protocol used by Windows Vista/XP
The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80. For other protocols, other default port numbers are used.The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80.
