I have been using TCPview lately to see what connections are made by different processes on my PC. Would somebody please explain what the following situations mean? Thanks.

TCP
Local Address: PC1234567890:3883
Remote Address: PC1234567890:0
State: LISTENING
TCP
Local Address: PC1234567890:4696
Remote Address: localhost:4697
State: ESTABLISHED

Local Address: PC1234567890:4697
Remote Address: localhost:4696
State: ESTABLISHED
UDP
Local Address: PC1234567890:1234
Remote Address: .
