<strong>Portlar</strong> Bilgisayar sistemlerinin birbirleriyle haberleşmek için kullandıkları Çıkış Kapılarıdır.Fiziksel ve Mantıksal olarak 2 kısma ayırabiliriz.<br /><strong>Fiziksel Portlar:</strong>LPT,COM,VGA,USB,IEEE 1394,...<br /><strong>Mantıksal Portlar :</strong>Adı üzerinde bunlar biraz daha Sanal.Asıl Haberleşmeyi yapanlar bunlar.Bunların sayısı teorikte <strong>65536</strong> tanedir ama biz günümüz uygulamalrıyla ancak 1000-1500 tanesini kullanabiliyoruz.<br /><br />Bütün portların Listesini burada veremedim.Aşağıdaki Linklerden detaylı bilgi alabilirsiniz.<br /><a href="http://www.networksorcery.com/enp/protocol/ip/ports00000.htm">http://www.networksorcery.com/enp/protocol/ip/ports00000.htm</a><br /><a href="http://www.iana.org/assignments/port-numbers">http://www.iana.org/assignments/port-numbers</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8426998650060774623-1512952333950098692?l=msisaserver.blogspot.com' alt='' /></div>Cryptologhttp://www.blogger.com/profile/11205421327100484747noreply@blogger.com0tag:blogger.com,1999:blog-8426998650060774623.post-33919811548066767202008-08-31T12:26:00.000-07:002008-08-31T12:33:39.484-07:00<a href="http://2.bp.blogspot.com/_dMzn23PQVGk/SLryC2Q-L6I/AAAAAAAAATI/QbLe6SmZzGg/s1600-h/aaavpn.JPG"><img style="float:left;
