Both TCP and IP are subprotocols in the OSI model. IP is used for routing purposes, whereas TCP is used for transport control.
If you are asking primarily about internetworking then it would be the IP protocol.
TCP is a sub-protocol within the IP protocol. Think of TCP as one of the instruments in a band.
Transmission control protocol/Internet Protocol or TCP/IP
The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP/IP.
Internetwork Packet Exchange. It was a protocol for Novell NetWare, but TCP/IP is so prevalent now, even IPX sites typically utilize it.
TCP IP is the protocol of choice when it comes to networking due to its ability to confirm the receipt of packets by the intended destination. As such, this protocol in email and web browsing.
the kind of protocl that isa used is the internet protocol (IP/TCP)
No TCP a reliable protocol whereas UDP is unreliable.
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
There are actually more than two protocols associated with Layer 4. According to Wikipedia, there are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Stream Control Transport Protocol (SCTP), Datagram Congestion Control Protocol (DCCP), and Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX).
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
TCP/IP is the standard default.
tcp based protocols,internet protocol,sometimes file transfer protocol also supported by tcp wrappers. tcp is reliable and connection oriented.
