Which port is used by MQTT in plain form?

Explanation:
MQTT uses a default port for plain, unencrypted TCP connections: 1883. This is the standard port assigned for MQTT traffic without TLS, while using TLS changes the port to 8883. The other numbers correspond to different services—636 is LDAP over SSL (LDAPS), 1433 is Microsoft SQL Server, and 3306 is MySQL—so they aren’t used for MQTT in its plain form.
