TCP/IP does not stand for internet protocol suite, but it is used when refereeing to this.
In fact, TCP/IP stands for transmission control protocol (TCP) and internet protocol (IP).
These two protocols were the first protocols to make up the internet protocol suite. For that reason, the industry has kept using the two when refereeing to the internet protocol suite as a whole.
The suite has four major layers. These are the application layer, and transport, internet and link layers.

On the application layer, some of the protocols include BGP, DHCP, DNS, FTP, HTTP, IMAP, LDAP, MGCP, NNTP, NTP, POP, ONC/RPC, RTP, RTSP, RIP, SIP, SMTP, SNMP, SSH ,Telnet, TLS/SSL, XMPP, and others.
On the transport layer, the major protocols include TCP, UDP, DCCP, SCTP and RSVP.
The internet layer includes more widely known protocols such as the IP protocol and its extensions IPv4 and IPv6. Other protocols are ICMP, ECN, EGMP, etc.
Lastly, on the link layer there is the ARP protocol, and the NDP, OSPF, PPP, MAC, and other protocols.
