Which port is commonly used by Microsoft SQL Server?

Explanation:
Knowing the default port for Microsoft SQL Server helps you connect to the database server over TCP. By default, SQL Server listens on TCP port 1433 for client connections, so a client specifying host:1433 will reach the default instance. The other ports belong to different services: 445 TCP is used for Windows file sharing (SMB), 3306 TCP is the default port for MySQL, and 1521 TCP is used by Oracle Database. Keep in mind that named instances can use dynamic ports, but 1433 is the standard default for the default SQL Server instance.
