Why is the IP called a connectionless protocol? If so, what is the connection-oriented protocol then?
Thanks.

I think, to b
TCP/IP means "TCP over IP".
TCP
--
IP
Notes:
Edit:
"connection-oriented" mean established end to end connection. For example, you pick up the telephone, call someone = you have a connection.
"connection-less" means "send it, see what happens". For example, sending a letter via snail mail.a
So IP gets your packets from A to B, maybe, in any order, not always eventually. TCP sorts them out, acknowledges them, requests a resends and provides the "connection"
