What are the Ports?

Port



In computer networks, a port is logically a set of network services or a code that provides communication over TCP/IP protocol suite which listens to various sorts of requests in networks while communicating locally or over the internet. Likewise, we could have hardware ports as well which connects different devices to each other. So, every protocol has some specific port or a range in which a port could bind if multiple applications are going to use the same port. There are a number of ports in networks, some of them are as below_


1 - DNS - 53


2 - DHCP Client - 68


3 - DHCP Server - 67


4 - RDP - 3389


5 - LDAP - 389


6 - FTP Server - 20


7 - FTP Client - 21


8 - SSH - 22


9 - Telnet                 - 23


10 - SMTP         - 25


11 - HTTP - 80


12 - HTTPS - 443


13 - POP3 - 110


14 - IMAP - 143


15 - UDP - 0 - 65535


16 - TFTP - 69


17 - GC (Global Catalogue) - 3268


18 - Kerberos - 88


19 - SMB - 445


20 - LDAP On SSL - 689

This number will keep going until you keep learning from computerflicks.
