( Explanation ) When NetBIOS is disabled, SMB runs over TCP/445. Kerberos runs on TCP/User Datagram Protocol (UDP)/88. RPC runs on TCP/135. HTTPS runs on TCP/443.
EIGRP uses port no. 88, but it is not use TCP or UDP, it's uses RTP(Reliable Transport Protocol).
Common Internet Protocol for browsing is TCP/IP.
Telnet use port number 23,and connected to TCP
Most email clients use one of three protocols to receive an email message. They are SMTP (Simple Mail Transfer Protocol), POP (Post Office Protocol), or IMAP (Internet Message Access Protocol).
Port 3389 is the only port you need to open. Windows will attempt to stream sound through User Datagram Protocol (UDP) first. If no port is available for UDP, sound will stream through a virtual channel in Remote Desktop Protocol, which uses port 3389. http://www.microsoft.com/windowsxp/using/mobility/rdfaq.mspx
139 & 445 (udp) and 138 & 137 (tcp)
TCP port 23
An SMTP port is the port used to transfer email using the SMTP protocol. Typically SMTP is configured to use TCP port 25, although some servers will use TCP port 587.
EIGRP uses port no. 88, but it is not use TCP or UDP, it's uses RTP(Reliable Transport Protocol).
IMAP (Internet Message Access Protocol) uses TCP (Transmission Control Protocol) for communication. The standard port for IMAP is 143, while the secure version, IMAPS, typically uses port 993. Unlike UDP, TCP provides a reliable connection, ensuring that messages are delivered in the correct order without loss.
For Send Mail Transfer protocol default port number as is 25. SMTP actually stands for Simple Mail Transfer Protocol. I agree with the port number
Telnet use port number 23,and connected to TCP
Common Internet Protocol for browsing is TCP/IP.

Some users have reported Yahoo! Chat and Upnp as using these ports, but there doesn't seem to be an "official" use of port 5000.TCP Port 5000 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
