It has a list of port -> protocol

go and buy some books on network programming
how old are you? 7?
"unix network programming" may be a good book to read
tcp/udp and ip are network protocols on a low level, your applications generally use a higher level protocol like http
http typically runs on top of tcp/ip |

| IP is in the network layer, tcp and udp are in the transport layer, http is in the application layer - each dependent upon and "riding on" the previous. |
