TCP/IP Protocol Suite - TSV

The TCP/IP Protocol Suite is a collection of communication protocols that enable data communication over the internet. It consists of four layers: Application, Transport, Internet, and Link layers, including major protocols such as TCP, UDP, IP, ICMP, ARP, DNS, HTTP, FTP, and SMTP. Standardized by the IETF and published as RFC documents, it forms the core of modern internet infrastructure.
