Several port protocols are designed to encrypt communications, including Secure Sockets Layer (SSL) and Transport Layer Security (TLS), commonly used with HTTPS (port 443) for secure web traffic. Other protocols include Secure Shell (SSH) on port 22 for secure remote access and File Transfer Protocol Secure (FTPS) on port 990 for secure file transfers. Additionally, Internet Protocol Security (IPsec) can encrypt data at the network layer, often used in Virtual Private Networks (VPNs).
The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80. For other protocols, other default port numbers are used.The default port number depends on the protocol. If a URL starts, for example, with "http://", then the default port number will be 80.

It depends on what SSL is being used for (HTTP, as in secure web pages; FTP; Telnet; etc.). Below is a non-exhaustive list of various port numbers used for protocols with SSL implemented: * HTTP: Port 443 * FTP (Data): Port 989 * FTP (Control): Port 990 * Telnet: Port 992 * IRC: Port 994 * pop3: Port 995 I hope this was the information you were looking for.
Yes, and they frequently do, although on different port numbers for different protocols.
Port numbers are generally not assigned in the same way as an IP address or even assigned at all. Ports are always there. They can be opened, closed or accessed by programs or protocols. So in answer to your question, organisations in general do not assign port numbers as they are not unique.
The Live Mail server typically uses the following port numbers for email communication: for incoming mail (IMAP), it uses port 993 for SSL/TLS connections and port 143 for non-encrypted connections. For POP3, the server uses port 995 for secure connections and port 110 for non-encrypted ones. For outgoing mail (SMTP), it generally operates on port 587 for secure submissions and port 25 for non-encrypted transmissions.

23 is for telnet,25 is for SMTP,20 is for FTP and 110 is for POP3
If I understand the question aright; different port numbers are used to identify different protocols. Port numbers between 1 and 1023 are well-known numbers and standards define which protocol uses which. FTP uses port number 21, HTTP uses port 80.
Different ports are used for each different protocol used by Instant Messaging. Some common protocols are Windows IM clients Port 1863 AOL Instant Messaging Port 5190 Jabber / XMPP Port 5222/5269 (or secure 5223)
NOPE
The SFTP port is used for secure logins, secure file transfer and port forwarding. It can be found on port 22 of the TCP protocol. The name of this port stands for Secure File Transfer Protocol.
