TCP/IP and TCP and IP difference? [closed]

Question

Is there a difference between TCP/IP and TCP and IP?

I thought always TCP/IP is just TCP and IP together but it looks like TCP/IP is a family that has a lot more protocols, not just TCP and IP.

• IP: Internetprotocol
• TCP: Transmission control protocol
• TCP/IP: Main protocols are TCP and IP, but it includes a lot more.

Did I understand that correct, or is that wrong?

Answer 1

In the following link you may distinguish the two models OSI and TCP/IP: http://electronicdesign.com/what-s-difference-between/what-s-difference-between-osi-seven-layer-network-model-and-tcpip

In case of TCP/IP model, it supports other protocols in different layers than 4 and 3, but also TCP protocol could be replaced by UDP or STCP and it will still remain as TCP/IP model.

Answer 2

When TCP and IP are mentioned separately then they mean a transport layer (RFC 793) and a network layer protocol (RFC 791) respectively. But when mentioned in TCP/IP format they mean a stack which TCP/IP suite.
