Looking for information on a computer port? This page, computer port page 801, has up to 100 port numbers that you can choose from. You may not know it, but there are more than 65,000 TCP ports and 65,000 UDP ports that computers use to communicate!
A port may send/receive data one direction at a time (simplex) or simultaneously in both directions (duplex); port communication may or may not be guaranteed depending on the portocol used. These computer / network ports may also connect internal programs on a single computer system.
