- PC - Buzz - I - IP - IP Ports

Kommunikationskanaler mellem TCP-protokollen og TCP/IP-applikations-protokoller.
16-bit numre: TCP og UDP har totalt 65.535 tilgængelige porte, hvoraf nogle er fast tilknyttet en bestemt protokol.

In order for a computer to connect to multiple Internet services at the same time, the concept of 'port' was introduced. Each computer has 65536 ports available. If your web browser initiates a connection to dshield.org for example, it will pick the first available port ( let say 12345) and use it to send the connection request to dshield.org . DShield.org's web server will reply to port 12345 on your PC. This way, your PC knows that this reply is in response to the request sent to dshield.org earlier.

The first 1024 ports are set aside for 'privileged use'. Usually, only servers that wait for incoming connections use these ports.
