Port numbers work like telephone extensions. Just as a office telephone system can use a main phone number and give each employee an extension number (like x300, x502, etc.),&#160; a computer has a main address and a set of port numbers to handle incoming and outgoing connections. With TCP and UDP, port numbers start at 0 and go up to 65535. Lower range numbers are dedicated to common Internet protocols like 21 for FTP, 80 for HTTP.</p></div><!-- [DocumentBodyEnd:7598b66e-2783-4082-a75a-a7f674e56267] --> Tue, 23 Aug 2011 22:43:10 GMT CommunityAdmin@leviton.com http://communities.leviton.com/message/3237?tstart=0#3237 2011-08-23T22:43:10Z 1 year, 9 months ago 0
