Port 1433 for TCP is needed to connect to the SQL database instance. By default, SQL will attempt to use 1433. If that port is unavailable, it will automatically choose another port. If this is the case, that port will need to be opened through the firewall instead.UDP port 1434 might be required for the SQL Server Browser Service when you're using named instances. The port number configured by the administrator. See the discussion below in the section Dynamic ports. TCP port 1434 for the default instance.
What service runs on port 143 : IMAP server
An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval.
What is port 1434 used for
SQL Server Browser service uses UDP static port 1434. It reads the registry for the assigned TCP port. SQL Server client library connects and sends a UDP message using port 1434. SQL Server Browser service gives back the port number of a specific instance.
What is the difference between SQL 1433 and 1434 : The default instance of SQL Server listens on Port 1433. Port 1434 is used by the SQL Browser Service which allows connections to named instances of SQL Server that use dynamic ports with out having to know what port each named instance is using, especially since this can change between restarts of the named instance.
UDP 1434 is used for Named SQL Server instances and SQL Browser service listens on this port for any incoming requests to a named sql server instance. The browser service will respond to the client with TCP port no. for the requested named instance. Select the Port type of the rule. Specify the ports 1433 and 1434 to which this rule applies inside the Specific local ports area. In this case, 1433 stands for the SQL server, and 1434 for the SQL server browser. In this step, leave the default selection: Allow the connection.

143 – this is the default port which does not provide any encryption. Port 993 is the secure port for IMAP and it works over TLS/SSL encryption.Port 143 (TCP/UDP) – IMAP – Internet Message Access Protocol – WhatPortIs.com.Open the Command Prompt and type 'telnet [IP address] 1434,' where IP address is the IP address of the remote server you are trying to connect with. If you receive an error message, “Could not open connection to the host, on port 1434: Connect failed,” this means that port 1434 is blocked on your network. Click the New Inbound Rule Wizard dialog and use the following information to create another port exception:

Is port 1434 safe : A Microsoft SQL Server reflection/amplification DDoS vector on UDP port 1434 was discovered and began being abused a few years ago and was immediately abused by attackers.
What is the difference between 993 and 143
143 – this is the default port which does not provide any encryption. Port 993 is the secure port for IMAP and it works over TLS/SSL encryption. Difference Between Port 993 and Port 143
You use port 993 for encrypted communication and port 143 for unencrypted communication. Both the email clients and the email server must use the same port.User Datagram Protocol (UDP)
The DHCP employs a connectionless service model, using the User Datagram Protocol (UDP). It is implemented with two UDP port numbers for its operations which are the same as for the bootstrap protocol (BOOTP). The server listens on UDP port number 67, and the client listens on UDP port number 68.
What runs on port 1434 : SQL Server
SQL Server uses UDP Port 1434 for communication with applications. If you are running an application that requires connectivity with the SQL Server, you must enable port 1434 for SQL Server to listen on.
